  • Changing Role of Pharmacist in Revision of Medical Fee, Atsushi Murase, Manabu Kitakoji, Toru Otori, Sumio Matzno, J Community Pharm Pharm Sci, J Community Pharm Pharm Sci, 11(2), 165 - 172, Oct. 2019 , Refereed
    Summary:In order to examine the role of the pharmacist in medical care, we analyzed “arrangement of the previous discussions related to the revision of medical service fees for 2014, 2016 and 2018”. Co-occurrence network analysis suggested that “hospital”, “patient” and “reevaluation” formed strongly connected cluster. “Patient” was also connected with other two groups. One group included “pharmacy”, “drug” and “management” and the other included “home”, “visit” and “nursing”. Furthermore, correspondence analysis suggested that 2014 had relations to “hospital” and “home”, 2016 had relations to “hospital”, “care” and “outpatients” and 2018 had relations not only to “doctor” and “drugs” but also “area”, “visit” and “support”. Therefore, the government’s policy to shift the role of the pharmacist from hospitals to home medical care was clarified.
  • The usefulness of self-evaluation rubric table as a component of a learning management system for a course in statistics, MATZNO Sumio, HACHIKEN Hiroko, 2, 159 - 166, Jan. 2019 , Refereed
    Summary:A self-evaluation rubric system was introduced to statistical classes for university students in order to investigate the relationship between students’ satisfaction and their grades. Two items, “understanding” and “computer skill”, were reviewed according to rubric tables. Principal component analysis revealed that most evaluations patterns indicated the same direction and students could be characterized into three groups. Whereas two factors of “teaching skill” and “students’ activity” were extracted from the post-course questionnaire. Finally, multiple regression analysis revealed that final examination results were well correlated with the evaluation rubric. This suggests that an evaluation rubric system is helpful to predict students’ achievement in class.

    Summary:ObjectivesTo avoid the chelate formation between levofloxacin (LVFX) and aluminium hydroxide in gastrointestinal tract, an ethoxycarbonyl 1-ethyl hemiacetal ester of levofloxacin (LVFX-EHE) was synthesised as a prodrug. MethodsThe effects of aluminium hydroxide on the bioavailability of LVFX following oral administration of LVFX-EHE were investigated in rats. Furthermore, the effects of aluminium hydroxide on small intestinal absorption of LVFX and LVFX-EHE when subjected to a hydrolysis experiment using in situ everted gut sac were investigated, and the minimal inhibitory concentrations (MICs) of LVFX and LVFX-EHE for various intestinal bacteria were measured. Key findingsWhen LVFX-EHE was co-administered with and without aluminium hydroxide, the AUC(0-4 h) values of LVFX hydrolysed from LVFX-EHE were similar to that of LVFX alone. In everted gut sac experiments, LVFX-EHE was efficiently absorbed even in the presence of aluminium ions after 1 h of incubation, whereas the absorption of LVFX decreased significantly in the presence of aluminium ions. MIC values of LVFX-EHE were far higher than LVFX. ConclusionsThis study suggests the benefit of ethoxycarbonyl 1-ethyl hemiacetal esterification of the carboxyl group of new quinolone as a prodrug which is able to avoid chelate formation.
  • Skb5, an SH3 adaptor protein, regulates Pmk1 MAPK signaling by controlling the intracellular localization of the MAPKKK Mkh1, Yuki Kanda, Ryosuke Satoh, Saki Matsumoto, Chisato Ikeda, Natsumi Inutsuka, Kanako Hagihara, Sumio Matzno, Sho Tsujimoto, Ayako Kita, Reiko Sugiura, JOURNAL OF CELL SCIENCE, JOURNAL OF CELL SCIENCE, 129(16), 3189 - 3202, Aug. 2016 , Refereed
    Summary:The mitogen-activated protein kinase (MAPK) cascade is a highly conserved signaling module composed of MAPK kinase kinases (MAPKKKs), MAPK kinases (MAPKK) and MAPKs. The MAPKKK Mkh1 is an initiating kinase in Pmk1 MAPK signaling, which regulates cell integrity in fission yeast (Schizosaccharomyces pombe). Our genetic screen for regulators of Pmk1 signaling identified Shk1 kinase binding protein 5 (Skb5), an SH3-domain-containing adaptor protein. Here, we show that Skb5 serves as an inhibitor of Pmk1 MAPK signaling activation by downregulating Mkh1 localization to cell tips through its interaction with the SH3 domain. Consistent with this, the Mkh13PA mutant protein, with impaired Skb5 binding, remained in the cell tips, even when Skb5 was overproduced. Intriguingly, Skb5 needs Mkh1 to localize to the growing ends as Mkh1 deletion and disruption of Mkh1 binding impairs Skb5 localization. Deletion of Pck2, an upstream activator of Mkh1, impaired the cell tip localization of Mkh1 and Skb5 as well as the Mkh1-Skb5 interaction. Interestingly, both Pck2 and Mkh1 localized to the cell tips at the G1/S phase, which coincided with Pmk1 MAPK activation. Taken together, Mkh1 localization to cell tips is important for transmitting upstream signaling to Pmk1, and Skb5 spatially regulates this process.

  • 中心静脈栄養法(TPN)施行時に脂肪乳剤が血清アルブミン値へ与える影響, 森住 誠, 坂本 千代子, 石原 美加, 松田 光弘, 松野 純男, 北小路 学, 日本病院薬剤師会雑誌, 日本病院薬剤師会雑誌, 51(6), 747 - 750, Jun. 2015 , Refereed
    Summary:静脈栄養時における脂肪乳剤の併用は、糖質の投与量や、総水分量を抑えた高エネルギー投与が可能となる。このようなメリットがあるにもかかわらず、我が国での脂肪乳剤併用率は低いのが実状である。そこで我々は、4週間以上の中心静脈栄養法(TPN)施行患者を対象に、脂肪乳剤の血清アルブミン(albumin:以下、Alb)値に影響を与える因子を重回帰分析にて探索した。その結果、Alb値に影響を与える因子として、非蛋白熱量(non-protein calorie:以下、NPC)における脂肪含有率、開始時Alb値、開始時C-reactive protein(以下、CRP)値、4週間後CRP値が挙げられた。以上の結果から、中心静脈栄養法開始時に低Alb血症でない場合や何らかの炎症性疾患を有する場合でのAlb値改善は困難だが、単に総エネルギー量を上げるのではなく、NPCにおける脂肪含有率がAlb合成に関与することを確認した。本研究から、静脈栄養時における脂肪乳剤の併用は栄養状態の改善に寄与する因子の1つであると考えられた。(著者抄録)
  • An Evaluation of Usage and Utilization of Generic Drugs by Clinical Medicine Departments Using a Questionnaire of Chain Community Pharmacies in Japan, Nagai Noriaki, Kim Yusei, Matzno Sumio, Matsuyama Kenji, Otori Toru, Jpn.J.Drug Inform., Jpn.J.Drug Inform., 16(3), 137 - 142, Nov. 2014 , Refereed
    Summary:The creation of the National Health Insurance program has greatly contributed to giving Japan the world's highest level of life expectancy.  However, the cost of medical care in Japan has increased as a result of an aging society.  In response to this reality, the Japanese government initiated a campaign to promote the use of generic drugs (GEs).  In order to clarify some of the trends that contribute to different clinical medicine department usages of GEs, we carried out a survey of 400 pharmacies.  The survey data was analyzed using linear regression analysis.  Analysis of linear equations derived "utilization" that indicated ease of use of GEs, and a "saturation acceptable value (maximum allowed)" that indicated usage of GEs.  The breakdown for different clinical medicine department usages of GEs was determined as the following: psychosomatic medicine or psychiatry was 11±0.13%, internal medicine was 29±0.18%, orthopedics was 18±0.14%, ophthalmology or otolaryngology was 15±0.14%, other departments was 17±0.15%.  Furthermore, the highest utilization derived by linear regression analysis was orthopedics.  The highest acceptable saturation value was for psychosomatic medicine or psychiatry, while the lowest acceptable saturation value was orthopedics.  The results of the study confirm the importance of establishing evaluation methods for GE usage, and that linear regression analysis is a powerful tool for revealing trends in GE usage among different departments.  Additionally, the study suggests that determining GE spread measures is valuable, since they can serve as an aid to future pharmaceutical administration consideration.
  • Multivariate Quantification of Acupuncture and Moxibustion Treatment in Combination with Questionnaire and Salivary Stress Markers, Sumio Matzno, Chie Ikeda, Kazuomi Watanabe, Ryohei Nakamura, Hanae Takamatsu, Jun Haginaka, Kenji Matsuyama, YAKUGAKU ZASSHI-JOURNAL OF THE PHARMACEUTICAL SOCIETY OF JAPAN, YAKUGAKU ZASSHI-JOURNAL OF THE PHARMACEUTICAL SOCIETY OF JAPAN, 134(5), 655 - 663, May 2014 , Refereed
    Summary:Pain and stress alleviation after acupuncture treatment was assessed in this study. Patients responded to a questionnaire designed to determine the amount of stress they were experiencing, and data were obtained for patient salivary amylase, cortisol, secretary IgA (s-IgA), and leptin receptor (OBRb). As a part of this study on acute pain, 6 factors were extracted from the questionnaire. The second factor (pain removal) was well correlated with salivary amylase activity in patients with cervico-omo-brachial syndrome. An evaluation of cumulative acupuncture treatments showed that salivary cortisol increased and s-IgA decreased. In addition, a decreased s-IgA level significantly correlated with chronic pain removal. The questionnaire correlated well with measurements of salivary markers suggesting that they can be taken as indices of therapeutic efficacy in acupuncture treatment.
  • FTY720 stimulated ROS generation and the Sty1/Atf1 signaling pathway in the fission yeast Schizosaccharomyces pombe, Kanako Hagihara, Aya Mizukura, Yuki Kitai, Mariko Yao, Kouki Ishida, Ayako Kita, Tatsuki Kunoh, Takashi Masuko, Sumio Matzno, Kenji Chiba, Reiko Sugiura, GENES TO CELLS, GENES TO CELLS, 19(4), 325 - 337, Apr. 2014 , Refereed
    Summary:Fingolimod hydrochloride (FTY720) is the first-in-class immune modulator known as sphingosine 1-phosphate (S1P) receptor agonists. FTY720 has also been reported to exert a variety of physiological functions such as antitumor effect, angiogenesis inhibition, and Ca2+ mobilization. Here, we show that FTY720 treatment induced reactive oxygen species (ROS) accumulation, and investigated the effect of FTY720 on the stress-activated MAP kinaseSpc1/Sty1, a functional homologue of p38 MAPK, using a Renilla luciferase reporter construct fused to the CRE, which gives an accurate measure of the transcriptional activity of Atf1 and thus serves as a faithful readout of the Spc1/Sty1 MAPK signaling in response to oxidative stresses. FTY720 stimulated the CRE responses in a concentration-dependent manner, which was markedly reduced by deletion of the components of the Spc1/Sty1 MAPK pathway. The blockade of ROS production by NAC (N-acetyl-l-cysteine) significantly reversed the FTY720-induced ROS accumulation, subsequent activation of the Spc1/Sty1 MAPK pathway, and inhibition of cell proliferation. Cells lacking the components of the Spc1/Sty1 MAPK exhibited higher sensitivity to FTY720 and higher ROS levels upon FTY720 treatment than in wild-type cells. Thus, our results demonstrate the usefulness of fission yeast for elucidating the FTY720-mediated signaling pathways involving ROS.

  • A search for the risk factors for hiccups and evaluation of antiemetic therapy in CDDP-based chemotherapy, using cluster analysis, Hajime Asano, Mizuki Watanabe, Akinori Kawaguchi, Masashi Yanae, Yoshinori Funakami, Tetsuyuki Wada, Sumio Matzno, Yuzuru Yamazoe, Shozo Nishida, Seiji Ichida, Japanese Journal of Cancer and Chemotherapy, Japanese Journal of Cancer and Chemotherapy, 40(8), 1031 - 1036, Aug. 2013 , Refereed
    Summary:Hiccups are often observed in patients treated with cisplatin (CDDP)-based chemotherapy. It has been reported that gender and specific dosages of CDDP and antiemetic drugs (e.g., dexamethasone and 5-HT3 receptor antagonist) using standard therapy are major risk factors in the onset of hiccups. Recently, aprepitant has been added to the antiemetic therapy in CDDP-based chemotherapy. However, it is not known how the onset of hiccups takes place in antiemetic therapy including aprepitant according to the guideline. In this study, we used cluster analysis to classify 229 patients treated with CDDP-based chemotherapy, to investigate the effect of antiemetic therapy on the onset of hiccups and chemotherapy-induced nausea and vomiting (CINV). Our analysis indicated that aprepitant was not a major risk factor for the onset of hiccups in the high CDDP dose group (≧70 mg/m2). However, an effect of antiemesis was confirmed in the standard therapy with aprepitant. In conclusion, we suggest that aprepitant is effective for CINV, without causing the onset of hiccups in patients treated with high-dose CDDP-based chemotherapy.

  • The potential of vitamin K(3) as an anticancer agent against breast cancer that acts via the mitochondria-related apoptotic pathway, Takeshi Akiyoshi, Sumio Matzno, Mika Sakai, Noboru Okamura, Kenji Matsuyama, CANCER CHEMOTHERAPY AND PHARMACOLOGY, CANCER CHEMOTHERAPY AND PHARMACOLOGY, 65(1), 143 - 150, Dec. 2009 , Refereed
    Summary:We tried to clarify the cytotoxic mechanism of VK(3) using the breast cancer cell line MCF-7. Cytotoxicity was measured via intracellular esterase activity. DNA fragmentation was assessed by agarose gel electrophoresis. JC-1 staining was applied to measure mitochondrial dysfunction. Caspase activation and reactive oxidative species (ROS) generation were also measured. VK(3) exhibited cytotoxicity that caused DNA fragmentation in MCF-7 cells with an IC(50) of 14.2 mu M. JC-1 staining revealed that VK(3) caused mitochondrial dysfunction including a disappearance of mitochondrial membrane potential. Additional investigation showed that the mitochondrial damage was induced by the generation of ROS and the subsequent activation of caspase-7 and -9. Our findings demonstrate that VK(3)-induced apoptosis is selectively initiated by the mitochondria-related pathway and might be useful in breast cancer chemotherapy.
  • Synergistic action of statins and nitrogen-containing bisphosphonates in the development of rhabdomyolysis in L6 rat skeletal myoblasts, Sumio Matzno, Tomoko Nishiguchi, Takeshi Akiyoshi, Setsuko Anami, Toshikatsu Nakabayashi, Kenji Matsuyama, JOURNAL OF PHARMACY AND PHARMACOLOGY, JOURNAL OF PHARMACY AND PHARMACOLOGY, 61(6), 781 - 788, Jun. 2009 , Refereed
    Summary:Objectives Nitrogen-containing bisphosphonates, which are widely used to treat osteoporosis, act as inhibitors of farnesyl pyrophosphate synthase, one of the key enzymes of the mevalonate pathway, and thus may have the potential to enhance the effect of statins (inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase). In this study, we evaluated the synergistic effect of two nitrogen-containing bisphosphonates, alendronate and risedronate, in statin-induced apoptosis in rat skeletal L6 myoblasts. Methods L6 rat myoblasts were differentiated with drugs. DNA fragmentation was measured and small GTPase was detected by immunoblotting. Key findings Alendronate and risedronate caused dose-dependent apoptosis of L6 myoblasts. Risedronate induced detachment of rho GTPase from the cell membrane, followed by activation of the caspase-8-related cascade. Risedronate-induced apoptosis was synergistically enhanced with atorvastatin and significantly reduced by addition of geranylgeraniol. By contrast, alendronate did not reduce membrane GTPases and the apoptosis was caspase independent. Conclusions These results suggest that risedronate-induced apoptosis is related to geranylgeranyl pyrophosphate depletion followed by rho detachment, whereas alendronate affects are independent of rho. Our results suggest a risk of synergistic action between nitrogen-containing bisphosphonates and statins in the development of rhabdomyolysis when treating osteoporosis in women with hyperlipidaemia.

  • An attempt to evaluate the effect of vitamin K-3 using as an enhancer of anticancer agents, Sumio Matzno, Yuka Yamaguchi, Takeshi Akiyoshi, Toshikatsu Nakabayashi, Kenji Matsuyama, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 31(6), 1270 - 1273, Jun. 2008 , Refereed
    Summary:The possibility of vitamin K-3 (VK3) as an anticancer agent was assessed. VK3 dose-dependently diminished the cell viability (measured as esterase activity) with IC50 of 13.7 mu M and Hill coefficient of 3.1 in Hep G(2) cells. It also decreased the population of S phase and arrested cell cycle in the G(2)/M phase in a dose-dependent manner. G(2)/M arrest was regulated by the increment of cyclin A/cdk1 and cyclin A/cdk2 complex, and contrasting cyclin B/cdk1 complex decrease. Finally, combined application demonstrated that VK3 significantly enhanced the cytotoxicity of etoposide, a G(2) phase-dependent anticancer agent, whereas it reduced the cytotoxic activity of irinotecan, a S phase-dependent agent. These findings suggest that VK3 induces G(2)/M arrest by inhibition of cyclin B/cdk1 complex formation, and is thus useful as an enhancer of G(2) phase-dependent drugs in hepatic cancer chemotherapy.
  • The possibility of simvastatin as a chemotherapeutic agent for all-trans retinoic acid-resistant promyelocytic leukemia, Naoki Tomiyama, Sumio Matzno, Chihiro Kitada, Eri Nishiguchi, Noboru Okamura, Kenji Matsuyama, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 31(3), 369 - 374, Mar. 2008 , Refereed
    Summary:In this study, the authors evaluated the possible use of 3-hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) in anti-leukemic chemotherapy. Cytotoxic potency against HL-60 was as follows; simvastatin (SV)>atorvastatin>cerivastatin>fluvastatin. Interestingly, HL-60-R2, an all-traits retinoic acid (ATRA)-resistant HL-60 variant, was twice as sensitive to SV than HL-60. Further studies revealed the particular mechanism of action of SV induced apoptosis in leukemia. SV directly and rapidly disordered mitochondria with a loss of its membrane potential, reactive oxygen species (ROS) generation and subsequent irreversible damage with cytochrome c leakage and, finally, SV induced apoptosis through caspase-9 activation, whereas several studies have shown that other statins induced apoptosis to leukemia by the depletion of isoprenoids used for the prenylation of small GTPases, which are essential for cellular signal transduction. Our findings suggest that the mitochondrial pathway plays an important role in the higher potency of SV as a new class of agents for anti-leukemic therapy alone and/or in combination with agents.
  • Effects of quinine on the intracellular calcium level and membrane potential of PC 12 cultures, Takeshi Akiyoshi, Naoko Tanaka, Tomoko Nakamura, Sumio Matzno, Kazumasa Shinozuka, Takahiro Uchida, JOURNAL OF PHARMACY AND PHARMACOLOGY, JOURNAL OF PHARMACY AND PHARMACOLOGY, 59(11), 1521 - 1526, Nov. 2007 , Refereed
    Summary:The mechanism for the perception of bitterness appears to be quite complicated, even for quinine, which is a model bitter substance, and thus has yet to be completely elucidated. To investigate the possibility of being able to predict the bitterness of quinine solutions, we examined the effects of quinine on intracellular calcium ion concentration ([Ca2+]i) and membrane potentials in PC 12 cultures. [Ca2+]i and membrane potentials were analysed by fluorescence confocal microscopic imaging using the Ca2+-sensitive probe Calcium Green 1/AM and the membrane potential-sensitive probe bis-(1,3-dibutylbarbituric acid) trimethine oxonol (DiBAC(4)(3)). Quinine elicited an increase in the membrane potential along with a concentration-dependent increase in [Ca2+]i. These increases were inhibited by extracellular Ca2+-free conditions, thapsigargin, which is a Ca2+-pump inhibitor, and U73122, which is a phospholipase C inhibitor. The quinine-induced increase in [Ca2+]i levels was inhibited by nifedipine, an L-type Ca2+-channel blocker, conotoxin, a T-type Ca2+-channel blocker, and BMI-40, which is a bitterness-masking substance. These results suggest that responses in PC 12 cultures may be used as a simple model of bitterness perception.
  • Flow cytometric evaluation of synergistic pro-apoptotic effects of statins and clofibrates in im-9 human lymphoblasts, Naoki Tomiyama, Noriko Yasuda, Chihiro Iwano, Sumio Matzno, Kenji Matsuyama, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, 34(9), 876 - 880, Sep. 2007 , Refereed
    Summary:In the present study, we evaluated fibrate-mediated potentiation of statin-induced apoptosis in IM-9 human lymphoblasts. The pro-apoptotic effects of statin and fibrate were measured by flow cytometry with biotin-annexin V, followed by addition of avidin-fluorescein isothiocyanate and propidium iodide. Apoptosis was confirmed using karyopyknotic staining, as well as detection of DNA fragmentation and caspase 3 activation. Incubation of IM-9 cells with both 0.1 mu mol/L cerivastatin and 200 mu mol/L clofibrate had a synergistic effect compared with 0.1 mu mol/L cerivastatin alone or 200 mu mol/L clofibrate alone. The magnitude of apoptosis induced by various combinations of statins and clofibrate were as follows: cerivastatin (0.1 mu mol/L) + clofibrate (200 mu mol/L) > atorvastatin (0.1 mu mol/L) + clofibrate (200 mu mol/L) > pravastatin (100 mu mol/L) + clofibrate (200 mu mol/L). Other fibrates (bezafibrate and clinofibrate) did not show any synergistic effect. Furthermore, karyopyknotic staining, caspase 3 activation and DNA fragmentation demonstrated synergistic pro-apoptotic effects of statin and fibrate. The results of the present study suggest that simultaneous treatment with statins and clofibrate could provide improved therapeutic efficacy in leukaemia patients.
  • Integrin beta 4 regulates migratory behavior of keratinocytes by determining laminin-332 organization, Bernd U. Sehgal, Phillip J. DeBiase, Sumio Matzno, Teng-Leong Chew, Jessica N. Claiborne, Susan B. Hopkinson, Alan Russell, M. Peter Marinkovich, Jonathan C. R. Jones, JOURNAL OF BIOLOGICAL CHEMISTRY, JOURNAL OF BIOLOGICAL CHEMISTRY, 281(46), 35487 - 35498, Nov. 2006 , Refereed
    Summary:hether alpha 6 beta 4 integrin regulates migration remains controversial. beta 4 integrin-deficient (JEB) keratinocytes display aberrant migration in that they move in circles, a behavior that mirrors the circular arrays of laminin (LM)-332 in their matrix. In contrast, wild-type keratinocytes and JEB keratinocytes, induced to express beta 4 integrin, assemble laminin-332 in linear tracks over which they migrate. Moreover, laminin-332-dependent migration of JEB keratinocytes along linear tracks is restored when cells are plated on wild-type keratinocyte matrix, whereas wild-type keratinocytes show rotation over circular arrays of laminn-332 in JEB keratinocyte matrix. The activities of Rac1 and the actin cytoskeleton-severing protein cofilin are low in JEB keratinocytes compared with wild-type cells but are rescued following expression of wild-type beta 4 integrin in JEB cells. Additionally, in wild-type keratinocytes Rac1 is complexed with alpha 6 beta 4 integrin. Moreover, Rac1 or cofilin inactivation induces wild-type keratinocytes to move in circles over rings of laminin-332 in their matrix. Together these data indicate that laminin-332 matrix organization is determined by the alpha 6 beta 4 integrin/actin cytoskeleton via Rac1/cofilin signaling. Furthermore, our results imply that the organizational state of laminin-332 is a key determinant of the motility behavior of keratinocytes, an essential element of skin wound healing and the successful invasion of epidermal-derived tumor cells.
  • Clofibrate-induced apoptosis is mediated by Ca2+-dependent caspase-12 activation, S Matzno, S Yasuda, Y Kitada, T Akiyoshi, N Tanaka, S Juman, K Shinozuka, T Nakabayashi, K Matsuyama, LIFE SCIENCES, LIFE SCIENCES, 78(16), 1892 - 1899, Mar. 2006 , Refereed
    Summary:The mechanism of fibrate-induced myopathy was investigated in this report. When clofibrate (30 to 300 mu M) was applied to L6 rat skeletal myoblasts, dose-dependently apoptosis was observed within 24 h. In the apoptotic myoblasts, a caspase-12 cleavage was observed at 2 It and with following caspases-9 and -3-related cascade activation. In contrast, the neutral protease calpain, that is a key enzyme in ER stress-related apoptosis via caspase-12 activation, was significantly decreased during apoptosis. Next, the authors evaluated a role of calcium-dependent signal(s). When clofibrate was added into medium, cytosolic calcium concentration was rapidly and persistently increased. On the other hand, an addition of 10 mM EGTA depressed sustained calcium phase, and concurrent myoblasts apoptosis was completely inhibited. Taken together, our findings indicate that the clofibrate-induced myopathy is triggered by Ca2+ influx, then activated cytosolic caspase-12 through calpain-independent cascade, and consequently caused apoptotic DNA fragmentation.

    Summary:Rhabdomyolysis is a severe adverse effect of 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins). This myopathy is strongly enhanced by the combination with statins and fibrates, another hypolipidaemic agent. We have evaluated the initial step of statin-induced apoptosis by the detection of membrane flip-flop using flow cytometric analysis. L6 rat myoblasts were treated with various statins (atorvastatin (3 mu M), cerivastatin (3 mu M), fluvastatin (3 mu M), pravastatin (3 mm), or simvastatin (3 mu M)) for 2, 4 or 6 h followed by reacting with FITC-conjugated annexin V for the detection of initial apoptosis signal (flip-flop). Various statin-treated myoblasts were significantly stained with FITC-annexin V at 6h, whereas they were not detected at 2h. Moreover, immunoblot analysis indicated that when the cells were treated with cerivastatin (3 pm), membrane-associated Ras protein was activated and detached until 6 h, resulting in cell death through the consequent activation of caspase-8. On the other hand, since cytosolic Ras activation did not activate, there is still an unknown mechanism in statin-related Ras depletion. In conclusion, statin-induced apoptosis in muscular tissue was directly initiated by the farnesyl-anchored Ras protein depletion from cell membrane with subsequent apoptosis.
  • Evaluation of apoptosis and necrosis induced by statins using fluorescence-enhanced flow cytometry, N Yasuda, S Matzno, C Iwano, M Nishikata, K Matsuyama, JOURNAL OF PHARMACEUTICAL AND BIOMEDICAL ANALYSIS, JOURNAL OF PHARMACEUTICAL AND BIOMEDICAL ANALYSIS, 39(3-4), 712 - 717, Sep. 2005 , Refereed
    Summary:The purpose of this study was to evaluate the apoptosis, and necrosis induced by five kinds of statins in IM-9 human lymphoblasts with fluorescence-enhanced flow cytometry using avidin-biotin complex. IM-9 human lymphoblasts (2 x 10(4) cells/cm(2)) were seeded into tissue culture plates and incubated with five kinds of statins. Statin-treated cells were first incubated with biotin-annexin V, followed by addition of avidin-FlTC and propidium iodide, and then subjected to flow cytometry. The fluorescence intensity was enhanced using an avidin-biotin complex system, resulting in successful separate determination of the statin-induced apoptosis and necrosis by flow cytometry, which enabled us to quantitatively evaluate the statin-induced cell damage. Flow cytometric analysis results in the intensity of statin-induced apoptosis in IM-9 cells as follows: atorvastatin = cerivastatin > fluvastatin > simvastatin > pravastatin. The intensity of statin-induced necrosis in IM-9 cells was expressed as follows: atorvastatin = cerivastatin > fluvastatin = sunvastatin > pravastatin. The total damage of IM-9 cells induced by five kinds of statins were expressed as the sum of both percentages of apoptosis and necrosis as follows: atorvastatin =. cerivastatin > fluvastatin = simvastatin > pravastatin. Our studies show that fluorescence enhancement with avidin-biotin complex is useful for the identification and quantitation of annexin-positive apoptosis cells and thus, the fluorescence-enhanced flow cytometry was shown to be applicable for screening of statins as new anti-leukemia agents.

  • Effect of quinine solutions on intracellular Ca2+ levels in neuro-2a cells - Conventional physiological method for the evaluation of bitterness, T Nakamura, T Akiyoshi, N Tanaka, K Shinozuka, S Matzno, T Nakabayashi, K Matsuyama, M Kashiwayanagi, T Uchida, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 26(11), 1637 - 1640, Nov. 2003 , Refereed
    Summary:The purpose of the present study was to examine the effect of quinine on intracellular Ca2+ ([Ca2+](i)) levels in cultured neuro-2a cells, and to investigate the possibility of using [Ca2+](i) levels to predict the bitterness of quinine solutions. [Ca2+](i) levels in neuro-2a cells increased following stimulation by quinine in a concentration-related manner. There was a good linear correlationship between the quinine-induced increase in [Ca2+](i) levels increase and the bitterness scores of the quinine solutions as assessed in human gustatory sensation tests (r(2)=0.918). The quinine-induced increase in [Ca2+](i) levels was inhibited by thapsigargin (an inhbitor of the Ca2+ pump into intracellular stores), U73122 (an inhibitor of phospholipase C) and omega-conotoxin (an N-type Ca2+- channel blocker), but not by nifedipine (an L-type Ca2+-channel blocker).
  • Risk of rhabdomyolysis by the concomitant use of vitamin supplements and HMG-CoA reductase inhibitors, Tazuya-Murayama Keiko, Matzno Sumio, Yamada Kazuko, Nakabayashi Toshikatu, Uchida Takahiro, Matsuyama Kenji, Mishima Motohiro, Japanese journal of food chemistry, Japanese journal of food chemistry, 10(2), 78 - 84, Aug. 29 2003 , Refereed
    Summary:HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A) reductase (EC inhibitors (statins) are used for hypercholestemia. HMG-CoA reductase is the rate-limiting enzyme of cholesterol biosynthesis. Rhabdomyolysis is one of the most serious side effects by statins. On the other hand, vitamins are used widely and easily for supplements of nutrition in daily use. Statins are one of the most marketable drugs for hypercholesterolemia. Vitamins are taken without prescription as supplements of nutrition ; the patient who prescribed statins may take vitamins. So the interaction with statins and vitamins were studied by using the in vitro assay system with L6 rat myoblasts. The myopathy was increased by the presence of vitamin A, vitamin D and nicotinic acid. Especially the severe injury was induced to the cells by vitamin A and vitamin D. The other vitamins, vitamin B_1, B_6, B_<12>, vitamin C and vitamin E did not show the reaction on the L6 cells. Taking vitamins together with statins increase the risk of rhabdomyolysis. The results of this study suggest that it is desirable for the person takes statins not to take vitamin A, vitamin D and nicotinic acid.
  • Evaluation of the synergistic adverse effects of concomitant therapy with statins and fibrates on rhabdomyolysis, S Matzno, K Tazuya-Murayama, H Tanaka, S Yasuda, M Mishima, T Uchida, T Nakabayashi, K Matsuyama, JOURNAL OF PHARMACY AND PHARMACOLOGY, JOURNAL OF PHARMACY AND PHARMACOLOGY, 55(6), 795 - 802, Jun. 2003 , Refereed
    Summary:Rhabdomyolysis is a severe adverse effect of hypolipidaemic agents such as statins and fibrates. We evaluated this muscular cytotoxicity with an in-vitro culture system. Cellular apoptosis was determined using phase-contrast and fluorescein microscopic observation with Hoechst 33342 staining. L6 rat myoblasts were treated with various statins and bezafibrate under various conditions. With statins only, skeletal cytotoxicity was ranked as cerivastatin>fluvastatin>simvastatin>atorvastatin> pravastatin in order of decreasing potency. Combined application of fibrates enhanced atorvastatin-induced myopathy, which causes little apoptosis alone. These results suggest that statins and fibrates synergistically aggravate rhabdomyolysis.
  • Calcium channel blocking and vasodilating actions of the novel dihydropyridine derivative AE0047, M Nishikawa, M Gohda, H Shinyama, S Matzno, K Yamanaga, H Kido, N Nakamura, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, 25(5), 347 - 354, May 1998 , Refereed
    Summary:1. The pharmacological characteristics of AE0047, a newly synthesized dihydropyridine (DHP) derivative, were investigated in vitro. 2. In bovine aortic membrane, AE0047 and other DHP calcium channel blockers (nitrendipine, nicardipine) displayed concentration-dependent antagonism to specific [H-3]-PN200-110 binding sites with the following values for inhibition constants (K-i) obtained: 20.8+/-8.9, 12.3+/-4.5 and 3.9+/-1.0 nmol/L for AE0047, nitrendipine and nicardipine, respectively, 3. In guinea-pig ventricular myocytes, AE0047 blocked the L-type calcium current, with values for the dissociation constant (K-d) and Hill coefficient of 11.4+/5.7 nmol/L and 0.852+/-0.061, respectively, indicating in the terms of Hill's hypothesis that one drug molecule blocks one calcium channel molecule. 4. In rat aorta, AE0047 inhibited Ca-45 uptake induced by high K+ (100 mmol/L) by 55%. 5. AE0047 and nitrendipine concentration dependently relaxed rat aortic strips contracted with 30 mmol/L KCl. The response to nitrendipine reached a plateau within 60 min and disappeared after drug washing, Interestingly, AE0047 required 5 h or more to produce a plateau of response, with no effect of drug washing, This confirmed the slow onset and long duration of its vasodilating action, 6. With AE0047, tissue content in rat aorta increased more slowly than with nitrendipine and release of AE0047 from tissue was also slower. 7. The data suggest that AE0047 is incorporated slowly into smooth muscle membranes, approaches receptors slowly through the membrane bilayer and accumulates in the membrane because of its high lipophilicity, resulting in an antihypertensive action that is slow in onset and of long duration.
  • Possible mechanism for the anti-atherosclerotic action of the calcium channel blocker AE0047 in cholesterol-fed rabbits, K Hayashi, T Imada, T Yamauchi, H Kido, H Shinyama, S Matzno, N Nakamura, Y Kagitani, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, 25(1), 17 - 25, Jan. 1998 , Refereed
    Summary:1, The present study was designed to investigate the antiatherosclerotic effect of AE0047, a calcium channel blocker, and to compare it with that of nilvadipine in cholesterol-fed rabbits, Furthermore, the effects of AE0047 on low-density lipoprotein (LDL) oxidation were studied in vitro, 2, A 7 week treatment period with AE0047 (3 and 10 mg/kg, p.o.) led to a dose-dependent reduction in the lipid deposition area by Oil Red-O staining (surface index) without affecting serum lipid levels, There was no reduction in the surface index following treatment with the same dose of nilvadipine (10 mg/kg), 3, In a vehicle-administered high-fat diet group of rabbits, levels of total cholesterol (TC) and esterified cholesterol (EC) and calcium content in the aorta were increased approximately two-to three-fold over those of the normal diet group, Increased levels of TC and EC and calcium content were reduced to the same levels as the normal diet group by AE0047 treatment, whereas nilvadipine did not affect TC and EC levels, 4, In an in vitro study, AE0047 (10 mu mol/L) inhibited LDL oxidation and the aggregation of apolipoprotein (Ape) B-100 induced by Cu2+, Furthermore, AE0047 inhibited the degradation of oxidized LDL by macrophages. In contrast, the same dose of nilvadipine (10 mu mol/L) did not inhibit either LDL oxidation or the aggregation of ApoB-100, 5, In summary, AE0047 inhibited LDL oxidation, resulting in a decrease of its uptake into macrophages and an inhibition of cholesterol esterification. This leads to an anti-atherosclerotic effect of AE0047, Thus, AE0047 may have therapeutic potential in preventing cardiovascular disease in hypertensive patients.
  • Inhibition of cholesterol biosynthesis by squalene epoxidase inhibitor avoids apoptotic cell death in L6 myoblasts, S Matzno, T Yamauchi, M Gohda, N Ishida, K Katsuura, Y Hanasaki, T Tokunaga, H Itoh, N Nakamura, JOURNAL OF LIPID RESEARCH, JOURNAL OF LIPID RESEARCH, 38(8), 1639 - 1648, Aug. 1997 , Refereed
    Summary:The relationship between the inhibition of cholesterol biosynthesis and occurrence of myopathy was studied in L6 myoblasts using two lines of cholesterol biosynthesis inhibitors, 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor (simvastatin) and squalene epoxidase inhibitors (TU-2078 and NB-598). All inhibitors completely inhibited the cholesterol synthesis in L6 myoblasts at doses of 1 and 3 mu M. Simvastatin (3 mu M) inhibited the fusion reaction of L6 myoblasts followed by the severe cellular damage. The myoblasts also had failed actin fiber formation and creatinine phosphokinase (CPK) production. Additionally, this agent also caused apoptotic cell death in differentiated L6 muscle fiber, indicating that skeletal myopathy by HMG-CoA reductase inhibitors seems to occur not only in differentiating immature myoblasts but also in matured skeletal myotubes. In contrast, TU-2078 and NB-598 had no effect on the fusion reaction of differentiating myoblasts or on the cellular viability of muscle fiber at 3 mu M, enough to completely inhibit cholesterol biosynthesis. It is conceivable that the mevalonate depletion and subsequent failure of ras farnesylation induced by simvastatin might cause the defects in differentiation and maintenance of the muscle fiber. Squalene epoxidase inhibitors did not show this adverse effect presumably because of the enzyme inhibition downstream of farnesyl synthesis. The present findings suggest the safe use of squalene epoxidase inhibitors in lipid-lowering therapy.
  • Possible mechanism of action of AE0047, a calcium antagonist, on triglyceride metabolism, K Hayashi, M Gohda, S Matzno, Y Kubo, H Kido, T Yamauchi, N Nakamura, JOURNAL OF PHARMACOLOGY AND EXPERIMENTAL THERAPEUTICS, JOURNAL OF PHARMACOLOGY AND EXPERIMENTAL THERAPEUTICS, 282(2), 882 - 890, Aug. 1997
    Summary:We evaluated the effect of AE0047, a dihydropyridine-type calcium antagonist, on the plasma lipid levels of obese Zucker rats, In rats treated orally with 3 to 10 mg/kg/day AE0047 for 7 days, plasma triglyceride CTG) and TG-rich lipoprotein levels dose-dependently decreased, whereas those of high-density lipoprotein cholesterol increased. Total cholesterol and low-density lipoprotein levels did not change. To elucidate the mechanism by which AE0047 decreases plasma TG levels, we examined the effect of AE0047 on the synthesis and secretion of TG-rich lipoproteins in human intestinal cell line Caco-2, as well as on the association and degradation of very low density lipoprotein (VLDL) in human hepatoblastoma cells HepG2. When Caco-2 cells were grown on a membrane filter and C-14-oleic acid was added to the apical side, 10(-5) and 10(-6) M AE0047 inhibited basolateral secretion of C-14-TG. AE0047 also suppressed the basolateral secretion of apolipoprotein B. In HepG2 cells, AE0047 increased the cellular uptake of I-125- VLDL. These results suggested that AE0047 decreased plasma TG level by the inhibition of intestinal chylomicron secretion and the enhancement of hepatic uptake of VLDL. AE0047 may be beneficial for the treatment of hypertensive patients with hypertriglyceridemia to reduce the risk factors of coronary heart disease.
  • AL0671, a new potassium channel opener, inhibits nonenzymatic glycation of protein and LDL oxidation, T Yamauchi, S Matzno, T Imada, M Eda, Y Inoue, N Nakamura, GENERAL PHARMACOLOGY, GENERAL PHARMACOLOGY, 27(2), 257 - 262, Mar. 1996 , Refereed
    Summary:1. The effects of AL0671, a navel potassium channel opener, on protein glycation and low density lipoprotein (LDL) oxidation were tested. 2. AL0671 dose dependently inhibited both fluorescence development of bovine serum albumin and cross linking of lysozyme. These inhibitory effects for glycation were no less potent than aminoguanidine. 3. AL0671 dose dependently inhibited both increase in negative charge and apo B-100 fragmentation during incubation of LDL with Cu2+. In addition, AL0671 significantly decreased the LDL degradation in rat peritoneal macrophages. 4. Neither pinacidil nor levcromakalim inhibited protein glycation and LDL oxidation. 5. Antioxidant properties of AL0671 might be due to its potent electron donating ability, and this agent is expected to be useful for hypertensive diabetes.
  • Synthesis and pharmacological evaluation of N-(6-functionalized-amino-3-pyridyl)-N'-bicycloalkyl-N''-cyanoguanidines as antihypertensive agents, M Eda, T Takemoto, T Okada, H Sakashita, S Matzno, M Gohda, K Hayashi, N Nakamura, C Fukaya, CHEMICAL & PHARMACEUTICAL BULLETIN, CHEMICAL & PHARMACEUTICAL BULLETIN, 44(2), 307 - 313, Feb. 1996 , Refereed
    Summary:A series of amino acid conjugates of N-(6-amino-3-pyridyl)-N'[exo-bicyclo[2.2.1]hept-2-yl]-N ''-cyanoguanidine (4) were prepared and evaluated as antihypertensive agents. The parent compound 4 showed potent potassium channel-opening and antihypertensive activities, but with undesirable changes of the urinary balance of electrolytes. However, alanine and histidine congeners (9,19) reduced this undesirable side effect of 4 through improved pharmacokinetics without loss of antihypertensive activity. They also provided additional information on the structural requirements for pinacidil-type potassium channel openers.
    Summary:1. We evaluated the mechanism of activation by AL0671, a novel potassium channel opener, of potassium current in rat aortic smooth muscle cells. 2. Under conditions of whole cell recording, AL0671 (1-1000 mu M) markedly increased potassium current with a Hill coefficient of 2 and dissociation constant of 1.5 x 10(-4) M. This activation was completely inhibited by intracellular ATP. 3. Under inside-out patch conditions, the ATP-sensitive K+ channels (K-ATP) treated with AL0671 (100 mu M) showed prolongation of the slower open time component and shortening of the slower closed time component without modification of channel conductance.
    Summary:Antihypertensive drugs are expected to have a lipid-lowering effect for use in treating ischemic heart disease. We evaluated the effect of (+)-N-(6-amino-3-pyridil)-N'-[(1S,2R,4R)-bicyclo-[2.2.1]hept-2-yl]-N''-cyanoguanidine hydrochloride (AL0671), a newly synthesized cyanoguanidine-derivative potassium channel opener, on serum lipid and lipoprotein levels in obese Zucker rats, a genetically engineered model of type IV hyperlipidemia. AL0671 dose-dependently decreased systolic blood pressure in obese Zucker rats. Serial administration (for 1 or 2 weeks) of AL0671 (5 mg/kg/day) significantly decreased serum total triglyceride, chylomicron and very-low-density lipoprotein levels with increasing high-density lipoprotein cholesterol, whereas low-density lipoprotein levels did not change. AL0671 (5 mg/kg/day) increased lipoprotein lipase activities 4-fold and hepatic triglyceride lipase activities 3-fold in postheparin plasma. Another urea-derivative compound, AL0674, whose potassium channel-opening activity is diminished, did not affect serum lipid and lipoprotein levels. These results suggested that AL0671 activates both lipoprotein lipase and hepatic triglyceride lipase activities through its potassium channel-opening activity followed by decreasing triglyceride-rich lipoproteins in genetically obese hyperlipemic rats. Therefore, AL0671 might be beneficial in the treatment of hypertensive patients with hypertriglyceridemia (probably with insulin resistance).
    Summary:The previous paper reported on the synthesis and pharmacological evaluation of N-(6-amino-3-pyridyl)-N'-bicycloalkyl-N''-cyanoguanidine derivatives, from among which three compounds were selected as potent potassium-channel openers. In the present study, selected compounds were tested for antagonism of potassium-induced contraction of rat aorta, hypotensive activity in normotensive rats, and diuretic activity in spontaneously hypertensive rats. This led to further evaluation of compound (+/-)-10 and selection of (+)-N-(6-amino-3-pyridyl)-N'-[(1S,2R,4R)-bicyclo[2.2.1]hept-2-yl]-N''-cyanoguanidine ((+)-10) (AL0670) for development as an antihypertensive agent. Although AL0670 is regarded as a pinacidil-type K+-channel opener, it showed different pharmacological and conformational profiles from pinacidil.
    Summary:This report describes the synthesis and pharmacological evaluation of a series of novel potassium channel openers related to the pinacidil-type compounds. Thioureas, cyanoguanidines, and pyridine N-oxides were systematically evaluated for their effects on both the inhibition of spontaneous mechanical activity in rat portal vein (in vitro) and their antihypertensive activity (in vivo), and the structure-activity relationship for this series of compounds was discussed. Good correlation between in vitro and iv antihypertensive activity was observed for these compounds. Among them, cyanoguanidines bearing a conformationally rigid unit such as a norbornyl group generally possessed potent activity in both in vitro and in vivo studies. Especially, N-(6-amino-3-pyridyl)-N'-cyano-N''-(1-methyl-2-norbornyl)guanidine (23d) was identified as a more potent potassium channel opener in vitro (EC(100) = 3 x 10(-8) M) than pinacidil (EC(100) = 10(-7) M).
    Summary:A monoclonal antibody (MAb) against human acrosome-reacted sperm was attached to paramagnetic polystyrene beads. Human sperm prepared by the swim-up method were 1) incubated in m-BWW, 2) incubated and ionophore treated, or 3) incubated with 5% seminal fluid. After treatment, sperm were mixed with the beads and incubated for 1 hr. Variously treated sperm showed different binding abilities to the beads. Sperm bound to the beads were collected by a magnet and subjected to triple staining. Most of the collected sperm were acrosome reacted. The results suggested that the beads can be used to estimate the acrosomal status of sperm, and that the use of antibody-coated paramagnetic beads provides a convenient way of collecting acrosome-reacted sperm. The acrosomal status detected by the beads was also compared with the ability of sperm to fuse with zona-free hamster eggs. It was found that greater bead-binding ability correlated with more sperm fusing with zona-free hamster eggs.
  • Fingolimod (FTY720) stimulates Ca2+/calcineurin signaling in fission yeast, Kanako Hagihara, Ayako Kita, Aya Mizukura, Mariko Yao, Yuki Kitai, Tatsuki Kunoh, Takashi Masuko, Sumio Matzno, Kenji Chiba, Reiko Sugiura, PLoS ONE, PLoS ONE, 8(12), e81907, Dec. 03 2013 , Refereed
    Summary:Fingolimod hydrochloride (FTY720) is the first in class of sphingosine 1-phosphate (S1P) receptor modulator approved to treat multiple sclerosis via down-regulation of G protein-coupled S1P receptor 1 by its phosphorylated form (FTY720-P). Many studies have revealed that FTY720 exerts various biological effects, including antitumor activities, angiogenesis inhibition, Ca 2+ mobilization and apoptosis, independently of S1P receptors. However, the exact mechanisms underlying their effects or signaling pathways mediated by FTY720 have not been completely established. To gain further insights into molecular mechanisms of FTY720 action, the effect of FTY720 on Ca2+ signaling in fission yeast was analyzed. The addition of Ca 2+ enhanced the sensitivity induced by FTY720, and mutants lacking genes required for calcium homeostasis, including calcineurin and its downstream transcription factor, Ppb1-responsive zinc finger protein (Prz1), were hypersensitive to FTY720 and CaCl2. The effect of FTY720 on calcineurin signaling was monitored by utilizing a luciferase reporter construct fused to three tandem repeats of the calcineurin-dependent response element (CDRE), which gives an accurate measure of calcineurin activity. The addition of FTY720 increased calcineurin activity as well as Ca2+ influx in a concentration-dependent manner. Notably, the FTY720-mediated Ca2+ influx and calcineurin activation were reduced markedly by the deletion of yam8+ or cch1+ encoding putative subunits of a Ca 2+ channel. Consistently, the deletion of Pmk1 mitogen-activated protein kinase (MAPK), which plays an important role in the activation of the Yam8/Cch1 channel, markedly decreased the intracellular Ca2+ levels upon FTY720 treatment. These results suggest that the FTY720-stimulated Ca 2+/calcineurin signaling activation partly involves the Yam8/Cch1 channel in fission yeast. © 2013 Hagihara et al.
  • Methods of preventing vinorelbine-induced phlebitis: An experimental study in rabbits, Emiko Kohno, Saori Murase, Mayumi Nishikata, Noboru Okamura, Sumio Matzno, Takashi Kuwahara, Kenji Matsuyama, International Journal of Medical Sciences, International Journal of Medical Sciences, 5(4), 218 - 223, Jul. 22 2008 , Refereed
    Summary:Purpose: In order to identify methods for preventing phlebitis caused by intravenous administration of vinorelbine (VNR), we established a procedure for estimating the severity of phlebitis in an animal model. Methods: Four different factors (administration rate, dilution, flushing, and infusion of fat emulsion) were evaluated for alleviation of phlebitis caused by VNR infusion. VNR was diluted with normal saline to prepare test solutions with concentrations of 0.6 mg/mL or 0.3 mg/mL for infusion into the auricular veins of rabbits. Two days after VNR infusion, the veins were subjected to histopathological examination. Results: VNR did not cause obvious loss of venous endothelial cells, the most sensitive and common feature of phlebitis, but VNR infusion led to inflammatory cell infiltration, edema, and epidermal degeneration. Tissue damage was significantly decreased by shortening the administration time and by diluting the VNR solution for infusion from 0.6 mg/mL to 0.3 mg/mL. However, there was no effect of flushing with normal saline after VNR infusion, while treatment with fat emulsion before and after VNR infusion only had a minimal effect. Conclusion: Rapid infusion and dilution are effective methods of reducing phlebitis caused by the infusion of VNR, but the efficacy of flushing with normal saline or infusion of fat emulsion was not confirmed. © Ivyspring International Publisher.

    Summary:The effects of vancomycin hydrochloride (VCM) and teicoplanin complex (TEIC) on hepatic function and renal function were evaluated in rats. VCM was injected via the jugular vein at doses of 40, 100, and 250 mg/kg, and TEIC was injected via the jugular vein at doses of 10, 30, 40, 50, and 60 mg/kg, both after being dissolved in 1 ml of saline solution. Increased doses of VCM significantly increased the integrated plasma concentrations, from 0 to 8 h, for blood urea nitrogen (BUN0-8) and serum creatinine (SCr 0-8). TEIC gave rise to a slight increase in both BUN0-8 and SCr0-8 as its dose was increased. On the other hand, TEIC significantly increased the integrated plasma concentrations, from 0 to 8 h, for aspartate aminotransferase (AST0-8), and alanine aminotransferase (ALT0-8), at doses from 40 mg/kg to 60 mg/kg, though VCM did not increase these concentrations. This study suggests the importance of paying attention to hepatic function - in addition to renal function - when TEIC is administered to patients with methicillin-resistant Staphylococcus aureus (MRSA). © Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases 2006.

    Summary:The petal of Hibiscus mutabilis L. f. versicolor MAKINO shows a white color after the flowering, and it gradually changes in the red. Though it is reported that the color changes are due to the storage of the anthocyanin in the petal vacuole, the mechanism has not been clarified. Thus, the mechanism of the color change was elucidated by expression analysis of mRNA of anthocyanidin synthetase (ANS) in the petal. Extraction and purification of mRNA: petals of white, pink and red organization of freezed fresh H. mutabilis were crushed in the liquid nitrogen and total RNA was extracted using the CTAB method, followed by the refinement of each mRNA by Purification Kit (TaKaRa). The several kinds of primer of actin and ANS were designed from the homology with other plants respectively and then RT-PCR was done using these primers. On cDNA fragment amplified by RT-PCR, the base sequence was analyzed by the conventional mannner. Using the primer which efficiently amplified the cDNA fragment, the expression of mRNA of the ANS with the change of the flower color was examined by RT-PCR. The amplified fragment of about 600bps was assigned to that of actin and the amplified fragment of about 500bps expressed only in the deep red petal was assigned to that of the ANS of H. mutabilis, referring to the sequence of actin and the ANS respectively. The amino acid sequence of mRNA of actin of H. mutabilis showed a homology over 91% with those of the other type plant and that of the ANS showed a homology over 82%. The expression level of mRNA of the ANS was consistent with the increase in the deep red from the white color. Furthermore, the color change was dependent on temperature but not the light.

Research Grants & Projects

  • Ministry of Education, Culture, Sports, Science and Technology, Grants-in-Aid for Scientific Research(基盤研究(C)), Possible mechanism of action of metabolic syndrome induction in patients treated with atypical antipsychotic agents, In this study, the authors evaluated the effect of atypical antipsychotic agents (SGAs) on metabolic syndrome induction. Using neuroblastoma cell lines, one of SGAs, olanzapine, induced 5HT_<2C> mRNA transcription in PC12 autonomic neuroblastoma. Furthermore, olanzapine also induced PPAR_γ translation and subsequent fat accumulation in 3T3L1 mouse adipoblastoma cell line. These results suggest that olanzapine induces metabolic syndrome by synergistic effect of both an activation of sympathetic nervous system and an elevation of direct differentiation of adipose tissues.
  • Ministry of Education, Culture, Sports, Science and Technology, Grants-in-Aid for Scientific Research(基盤研究(C)), Evaluation of New Agents modified Vitamin K of anticancer which inhibited cdc 25 phosphatase, The possibility of vitamin K3 (VK3) as an anticancer agent was assessed. VK3 dose-dependently diminished the cell viability (measured as esterase activity) with 1050 of 13. 7mM and Hill coefficient of 3. 1 in Hep G2 cells. It also decreased the population of S phase and arrested cell cycle in the G2/M phase in a dose-dependent manner. G2/M arrest was regulated by the increment of cyclin A/cdk1 and cyclin A/cdk2 complex, and contrasting cyclin B/cdk1 complex decrease. Finally, combined application demonstrated that VK3 significantly enhanced the cytotoxicity of etoposide, a G2 phase-dependent anticancer agent, whereas it reduced the cytotoxic activity of irinotecan, a S phase-dependent agent. These findings suggest that VK3 induces G2/M arrest by inhibition of cyclin B/cdk1 complex formation, and is thus useful as an enhancer of G2 phase-dependent drugs in hepatic cancer chemotherapy.
