    Summary:Rats stressed by specific alternation of rhythm in temperature (SART) show various symptoms of disautonomia, continuous hypotension and tachycardia. In our study, we investigated postural change-induced orthostatic hypotension (OH) in SART-stressed rats. Each rat was restrained on a board in a supine position under anesthesia. In the SART-stressed rats during rest, both systolic and diastolic blood pressure (BP) were low and heart rate was fast, as in awake rats. Postural change was caused by tilting the rat's head up at a 60°angle for 4min. As indexes of OH, three values were used : (1) the maximum decrease in BP, (2) the reflex ratio, and (3) the area enclosed by the baseline and the time-related BP curve (AUC). In comparison to unstressed rats, SART-stressed rats showed the following changes : the maximum decrease in BP was significantly larger, the reflex-induced recovery from the maximum decrease in BP was significantly smaller, and the AUC was significantly larger. Heart rate in the stressed rats decreased soon after tilting, while it increased in unstressed rats. We conclude that postural change in SART-stressed rats can be used as an animal model of OH.

  • Repeated Cold Stress Reduces Cyclophosphamide-Induced Cystitis/Bladder Pain and Macrophage Activity in Mice, Maho Tsubota, Tomoyoshi Miyamoto, Saki Hiruma, Haruka Saeki, Takaya Miyazaki, Fumiko Sekiguchi, Yoshinori Funakami, Atsufumi Kawabata, PHARMACOLOGY, PHARMACOLOGY, 99(5-6), 286 - 290, 2017 , Refereed
    Summary:We examined the effect of repeated cold (RC) stress on cyclophosphamide (CPA)-induced cystitis/bladder pain in mice, in relation to macrophage activity. CPA, given i.p. at 400 mg/kg, caused bladder pain symptoms accompanying cystitis in both unstressed and RC-stressed mice, which were prevented by the macrophage inhibitor minocycline. A low dose, that is, 200 mg/kg, of CPA still produced bladder pain symptoms in unstressed but not RC-stressed mice. Lipopoly-saccharide-induced cytokine production in peritoneal macrophages from RC-stressed mice was less than that from unstressed mice. Thus, RC stress appears to reduce CPA-induced bladder pain in mice, which may be associated with the decreased macrophage activity. (C) 2017 S. Karger AG, Basel
  • Repeated Cold Stress Enhances the Acute Restraint Stress-Induced Hyperthermia in Mice, Tomoyoshi Miyamoto, Yoshinori Funakami, Erika Kawashita, Ai Nomura, Nanako Sugimoto, Haruka Saeki, Maho Tsubota, Seiji Ichida, Atsufumi Kawabata, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 40(1), 11 - 16, Jan. 2017 , Refereed
    Summary:The rodents exposed to repeated cold stress according to a specific schedule, known as specific alternation of rhythm in temperature (SART), exhibit autonomic imbalance, and is now used as an experimental model of fibromyalgia. To explore the susceptibility of SART-stressed animals to novel acute stress, we tested whether exposure of mice to SART stress for 1 week alters the extent of acute restraint stress-induced hyperthermia. Mice were subjected to 7-d SART stress sessions; i.e., the mice were alternately exposed to 24 and 4 degrees C at 1-h intervals during the daytime (09:00-16:00) and kept at 4 degrees C overnight (16:00-09:00). SART-stressed and unstressed mice were exposed to acute restraint stress for 20-60 min, during which rectal temperature was monitored. Serum corticosterone levels were measured before and after 60-min exposure to restraint stress. SART stress itself did not alter the body temperature or serum corticosterone levels in mice. Acute restraint stress increased the body temperature and serum corticosterone levels, both responses being greater in SART-stressed mice than unstressed mice. The enhanced hyperthermic responses to acute restraint stress in SART-stressed mice were significantly attenuated by SR59230A, a beta(3) adrenoceptor antagonist, but unaffected by diazepam, an anxiolytic, mifepristone, a glucocorticoid receptor antagonist, or indomethacin, a cyclooxygenase inhibitor. These results suggest that SART stress enhances the susceptibility of mice to acute restraint stress, characterized by increased hyperthermia and corticosterone secretion, and that the increased hyperthermic responses to acute stress might involve accelerated activation of sympathetic beta(3) adrenoceptors, known to regulate non-shivering thermogenesis in the brown adipose tissue.
  • Enhanced Hyperthermic Responses to Lipopolysaccharide in Mice Exposed to Repeated Cold Stress, Tomoyoshi Miyamoto, Yoshinori Funakami, Erika Kawashita, Shiori Tomita, Ai Nomura, Nanako Sugimoto, Haruka Saeki, Takaya Miyazaki, Maho Tsubota, Seiji Ichida, Atsufumi Kawabata, PHARMACOLOGY, PHARMACOLOGY, 99(3-4), 172 - 178, 2017 , Refereed
    Summary:Lipopolysaccharide (LPS) induces hyperthermia accompanied by various other systemic inflammatory symptoms. The rodents exposed to repeated cold (RC) stress according to a specific schedule are useful as experimental models for autonomic imbalance or fibromyalgia. It is now proven that RC-stressed mice exhibit tolerance to LPS, we examined thermal responses to LPS challenge in RC-stressed mice by monitoring core temperature using the telemetry system. Systemic administration of LPS caused bimodal hyperthermic responses in RC-stressed and unstressed mice. The magnitude of the LPS-induced hyperthermia was greater in RC-stressed mice than in unstressed mice. The RC stress-induced enhancement of hyperthermic responses to LPS was abolished by pretreatment with diclofenac, which is a cyclooxygenase (COX) inhibitor. LPS did not significantly increase COX-2 protein levels in the lung or hypothalamus of RC-stressed or unstressed mice. RC stress did not alter baseline serum corticosterone levels or their increases in response to LPS challenge. These results suggest that RC stress enhances the susceptibility of mice to LPS challenge, leading to greater prostanoid-dependent hyperthermia, which might contribute to tolerance to LPS in RC-stressed mice.

  • Intravenous Administration of Cilostazol Nanoparticles Ameliorates Acute Ischemic Stroke in a Cerebral Ischemia/Reperfusion-Induced Injury Model, Noriaki Nagai, Chiaki Yoshioka, Yoshimasa Ito, Yoshinori Funakami, Hiroyuki Nishikawa, Atsufumi Kawabata, INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES, INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES, 16(12), 29329 - 29344, Dec. 2015 , Refereed
    Summary:It was reported that cilostazol (CLZ) suppressed disruption of the microvasculature in ischemic areas. In this study, we have designed novel injection formulations containing CLZ nanoparticles using 0.5% methylcellulose, 0.2% docusate sodium salt, and mill methods (CLZ(nano) dispersion; particle size 81 +/- 59 nm, mean +/- S.D.), and investigated their toxicity and usefulness in a cerebral ischemia/reperfusion-induced injury model (MCAO/reperfusion mice). The pharmacokinetics of injections of CLZ(nano) dispersions is similar to that of CLZ solutions prepared with 2-hydroxypropyl--cyclodextrin, and no changes in the rate of hemolysis of rabbit red blood cells, a model of cell injury, were observed with CLZ(nano) dispersions. In addition, the intravenous injection of 0.6 mg/kg CLZ(nano) dispersions does not affect the blood pressure and blood flow, and the 0.6 mg/kg CLZ(nano) dispersions ameliorate neurological deficits and ischemic stroke in MCAO/reperfusion mice. It is possible that the CLZ(nano) dispersions will provide effective therapy for ischemic stroke patients, and that injection preparations of lipophilic drugs containing drug nanoparticles expand their therapeutic usage.
  • Phloridzin-sensitive transport of echinacoside and acteoside and altered intestinal absorption route after application of Cistanche tubulosa extract, Tadatoshi Tanino, Noriaki Nagai, Yoshinori Funakami, JOURNAL OF PHARMACY AND PHARMACOLOGY, JOURNAL OF PHARMACY AND PHARMACOLOGY, 67(10), 1457 - 1465, Oct. 2015 , Refereed
    Summary:ObjectivesThe objective of this study was to address the beneficial effects of Cistanche tubulosa extract on improving the low intestinal permeability of echinacoside (ECH) and acteoside (ACT).MethodsAbsorption of ECH and ACT in C.tubulosa extract was characterized using human intestinal Caco-2 cell monolayers with intact compounds. Glucose transporter-dependent absorption of ECH and ACT was confirmed by an in-situ intestinal perfusion technique.Key findingsThe apparent permeability (P-app) was not significantly different between intact ECH and intact ACT. In the presence of phloridzin, the P-app of the ECH and ACT at a high dose was reduced to 20% of the respective non-treatment, but was not altered by phloretin and verapamil. C.tubulosa extract at low and high doses enhanced the P-app of ECH and ACT (both by threefold), resulting in their large participation in sodium-dependent glucose transporter-independent absorption. At a low concentration, concomitant ECH and ACT levels in portal blood were significantly suppressed by phloridzin.ConclusionThe dietary and medicinal C.tubulosa extract enhancing the intestinal absorption of ECH and ACT may serve to better manage human health, although the involvement of phloridzin-sensitive transport should be reduced.
  • Cyclosporin A-sensitive cytotoxicity of flurbiprofen non-stereoselectively mediated by cytochrome P450 metabolism in three-dimensional cultured rat hepatocytes, Tadatoshi Tanino, Yoshinori Funakami, Noriaki Nagai, Yoshihisa Kato, JOURNAL OF PHARMACY AND PHARMACOLOGY, JOURNAL OF PHARMACY AND PHARMACOLOGY, 67(10), 1406 - 1415, Oct. 2015 , Refereed
    Summary:Objectives2-Arylpropionic acid (profen) drugs are associated with severe hepatotoxicity; however, risk factors are still poorly understood. Acyl-coenzyme A (acyl-CoA) thioesters of profen drugs play a more important role in the covalent binding to rat hepatocyte proteins than the respective acyl-glucuronides. Therefore, we examined whether acyl-glucuronides, acyl-CoA thioesters and oxidative metabolites of profen drugs stereoselectively participated in liver damage.MethodsCytotoxicity was determined by measuring lactate dehydrogenase (LDH) leakage from three-dimensional cultured rat hepatocytes.Key findingsLDH leakage was not induced by R-2-phenylpropionic acid and R-ibuprofen greatly forming acyl-CoA thioesters. S-Naproxen metabolized mainly by Uridine 5-diphosphate (UDP)-glucuronosyl-transferase did not enhance LDH leakage. However, flurbiprofen (FLP) induced LDH leakage. A selective cytochrome P450 (CYP) 2C11 inhibitor suppressed 40-50% of the R-FLP and S-FLP-induced cytotoxicity. Borneol non-stereoselectively accelerated the FLP-induced cytotoxicity. The R-FLP-induced cytotoxicity decreased intracellular adenosine triphosphate (ATP) levels to 50% of untreated hepatocytes. An inhibitor of mitochondrial permeability transition pore, cyclosporin A (Cys A), rescued ATP levels and LDH leakage back to control levels.ConclusionThe reactive acyl-CoA thioesters and acyl-glucuronides were not associated with liver damage, denying one of the leading hypotheses. CYP metabolism of FLP non-stereoselectively participated in Cys A-sensitive cytotoxicity, suggesting mitochondrial injury.
  • Hypercalcemia Leads to Delayed Corneal Wound Healing in Ovariectomized Rats, Noriaki Nagai, Fumihiko Ogata, Naohito Kawasaki, Yoshimasa Ito, Yoshinori Funakami, Norio Okamoto, Yoshikazu Shimomura, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 38(7), 1063 - 1069, Jul. 2015 , Refereed
    Summary:Hypercalcemia is often observed in postmenopausal women as well as in patients with primary hyperparathyroidism or malignant tumors. In this study, we investigated the relationship between calcium ion (Ca2+) levels in lacrimal fluid and the rate of corneal wound healing in hypercalcemia using ovariectomized (OVX) rat debrided corneal epithelium. We also determined the effects of Ca2+ levels on cell adhesion, proliferation and viability in a human cornea epithelial cell line (HCE-T). The calcium content in bones of OVX rats decreased after ovariectomy. Moreover, the Ca2+ content in the blood of OVX rats was increased 1 month after ovariectomy, and decreased. The Ca2+ content in the lacrimal fluid of OVX rats was also increased after ovariectomy, and then decreased similarly as in blood. Corneal wound healing in OVX rats was delayed in comparison with Sham rats (control rats), and a close relationship was observed between the Ca2+ levels in lacrimal fluid and the rate of corneal wound healing in Sham and OVX rats (y=-0.7863x+8.785, R=0.78, n=25). In addition, an enhancement in Ca2+ levels caused a decrease in the viability in HCE-T cells. It is possible that enhanced Ca2+ levels in lacrimal fluid may cause a decrease in the viability of corneal epithelial cells, resulting in a delay in corneal wound healing. These findings provide significant information that can be used to design further studies aimed at reducing corneal damage of patients with hypercalcemia.
  • PKC/MEK inhibitors suppress oxaliplatin- induced neuropathy and potentiate the antitumor effects, Masanobu Tsubaki, Tomoya Takeda, Tadahumi Tani, Hirotaka Shimaoka, Naohiro Suzuyama, Kotaro Sakamoto, Arisa Fujita, Naoki Ogawa, Tatsuki Itoh, Motohiro Imano, Yoshinori Funakami, Seiji Ichida, Takao Satou, Shozo Nishida, INTERNATIONAL JOURNAL OF CANCER, INTERNATIONAL JOURNAL OF CANCER, 137(1), 243 - 250, Jul. 2015 , Refereed
    Summary:Oxaliplatin is a key drug commonly used in colorectal cancer treatment. Despite high clinical efficacy, its therapeutic application is limited by common, dose-limiting occurrence of neuropathy. As usual symptomatic neuropathy treatments fail to improve the patients' condition, there is an urgent need to advance our understanding of the pathogenesis of neuropathy to propose effective therapy and ensure adequate pain management. Oxaliplatin-induced neuropathy was recently reported to be associated with protein kinase C (PKC) activation. It is unclear, however, whether PKC inhibition can prevent neuropathy. In our current studies, we found that a PKC inhibitor, tamoxifen, inhibited oxaliplatin-induced neuropathy via the PKC/extracellular signal-regulated kinase (ERK)/c-Fos pathway in lumbar spinal cords (lumbar segments 4-6). Additionally, tamoxifen was shown to act in synergy with oxaliplatin to inhibit growth in tumor cells-implanted mice. Moreover, mitogen-activated protein kinase kinase (MEK) 1/2 inhibitor, PD0325901, suppressed oxaliplatin-induced neuropathy and enhanced oxaliplatin efficacy. Our results indicate that oxaliplatin-induced neuropathy is associated with PKC/ERK/c-Fos pathway in lumbar spinal cord. Additionally, we demonstrate that disruption of this pathway by PKC and MEK inhibitors suppresses oxaliplatin-induced neuropathy, thereby suggesting that PKC and MEK inhibitors may be therapeutically useful in preventing oxaliplatin-induced neuropathy and could aid in combination antitumor pharmacotherapy.
  • Differential Expression of the 5-HT3A and 5-HT3B Receptor in Differentiated NG108-15 Cells, Hajime Asano, Akinori Miyamoto, Mariko Nakao, Chiyuki Wakaki, Takuma Iida, Yoshinori Funakami, Tetsuyuki Wada, Seiji Ichida, NEUROCHEMICAL RESEARCH, NEUROCHEMICAL RESEARCH, 37(8), 1738 - 1746, Aug. 2012 , Refereed
    Summary:Previous work from this laboratory has shown that the serotonin (5-HT) induced response is significantly augmented in differentiated NG108-15 (NG) cells treated with dibutyryl cAMP (Bt(2)cAMP) due to qualitative and quantitative changes in the expression of the 5-HT3 receptor as demonstrated by specific [H-3] LY-278584 (a selective 5HT(3) receptor antagonist) binding. In this study, we investigated whether there is any change in the relative expression of the 5-HT3A and 5-HT3B subunits in NG cells differentiated following Bt(2)cAMP treatment cells. The major findings of this study were that the relative amount of 5-HT3B subunit mRNA in Bt(2)cAMP-treated NG cells 5 days following Bt(2)cAMP-treatment was greater than that in the untreated cells. In contrast, the relative expression of the 5-HT3B subunit protein in the Bt(2)cAMP-treated NG cells was much less than in the untreated cells, but the relative expression of the 5-HT3A subunit in the Bt(2)cAMP-treated NG cells was similar to the untreated cells. Therefore, no relationship between mRNA and protein expression for 5-HT3A and 5-HT3B subunits in Bt(2)cAMP treated and untreated NG cells were observed. It was also found that fluorescent intensity for the 5-HT3B subunit in the cell body of the Bt(2)cAMP treated and untreated NG cells gradually decreased from the day 1-5 after Bt(2)cAMP treatment. However, in specific areas such as the varicosity and nerve endings of the Bt(2)cAMP treated cells, staining intensity for the 5-HT3B subunits was stronger than in the untreated cells at the all time points, peaking at day 5 post-treatment. These results suggest that the augmented response induced by 5-HT acting via 5-HT3 receptors in differentiated NG cells may be due to changes in the relative amount of the 5-HT3B subunit, particularly the ratio and distribution of the 5-HT3A to (3B) subunits.
  • Specific Alternation of Rhythm in Temperature (SART) Stress-Induced Irritable Bowel Syndrome-Like Changes in Mice and Effects of Drugs, Yoshinori Funakami, Eiji Itoh, Taeko Hata, Tetsuyuki Wada, Seiji Ichida, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 33(9), 1545 - 1549, Sep. 2010 , Refereed
    Summary:Stress is closely associated with the manifestation and progress of irritable bowel syndrome (IBS). For the purpose of establishing experimentally the relationship between IBS and stress, the transportation capacity of the small intestine in specific alternation of rhythm in temperature (SART)-stressed animals was studied using charcoal transportation method. The charcoal suspension was administered orally into the stomach of fasting mice. Mice were sacrificed after a certain time and %charcoal transit (%CT) of the small intestine was measured. The %CTs in SART-stressed mice were greater than those in unstressed or continuously cold-stressed mice. This increase in %CT remained for I week after discontinuation of SART stress loading. Cholinergic blockers decreased %CTs in SART-stressed mice. Increases in %CT by a cholinesterase inhibitor were less in SART-stressed mice than in unstressed mice. Increases of %CT in SART-stressed mice were suppressed by Neurotropine. These results suggested that the parasympathetic hypertonicity, not just cold, played a role in the increases in the transportation capacity in SART-stressed mice and that these animals can be a useful tool for elucidation of the mechanism of IBS.
  • Changes in Characteristics of the Specific Binding of [H-3]LY-278584, a 5-HT3-Receptor Antagonist, on Differentiated NG108-15 Cells, Kayoko Matsushima, Takashi Imanishi, Hajime Asano, Yoshinori Funakami, Tetsuyuki Wada, Seiji Ichida, JOURNAL OF PHARMACOLOGICAL SCIENCES, JOURNAL OF PHARMACOLOGICAL SCIENCES, 113(3), 281 - 284, Jul. 2010 , Refereed
    Summary:We have reported previously that the concentration of intracellular Ca2+ evoked by serotonin (5-HT) was significantly augmented in differentiated NG108-15 (NG) cells treated with dibutyryl cAMP and the enhanced response occurred via 5-HT3 receptors. We investigated changes in the characteristics for specific binding of [H-3]LY-278584 (a specific antagonist of the 5-HT3 receptor) on membranes from differentiated NG cells. The results indicated that the K-d and B-max values for the specific binding to differentiated NG cells were significantly smaller and larger, respectively, than those for undifferentiated NG cells. The binding was significantly inhibited by 10 nM tropisetron, a specific 5-HT3 receptor antagonist, but not by any other types of 5-HT receptor antagonists. These results suggested that the enhanced response by 5-HT in differentiated NG cells was due to both qualitative and quantitative changes in the 5-HT3 receptor.
  • Characteristics for Enhanced Response of Serotonin-Evoked Ion Dynamics in Differentiated NG108-15 Cells, Takashi Imanishi, Kayoko Matsushima, Akinori Kawaguchi, Hajime Asano, Yoshinori Funakami, Tetsuyuki Wada, Takashi Masuko, Shigeru Yoshida, Seiji Ichida, NEUROCHEMICAL RESEARCH, NEUROCHEMICAL RESEARCH, 34(5), 1011 - 1019, May 2009 , Refereed
    Summary:Characteristics for the up-regulated response in the concentration of intracellular calcium ion ([Ca(2+)] (i) ) and in the sodium ion (Na(+)) current by serotonin (5-HT) were investigated in differentiated neuroblastoma x glioma hybrid NG108-15 (NG) cells. The results for the changes in [Ca(2+)] (i) by 5-HT were as follows, (1) The 5-HT-induced Ca(2+) response was inhibited by 3 x 10(-9) M tropisetron (a 5-HT(3) receptor blocker), but not by other types of 5-HT receptor blockers; (2) The 5-HT-induced Ca(2+) response was mainly inhibited by calciseptine (a L-type Ca(2+) blocker), but not by other types of Ca(2+) channel blockers or 10(-7) M TTX (a voltage-sensitive Na(+) channel blocker); (3) When the extracellular Na(+) was removed by exchange with choline chloride or N-methyl-d-glucamine, the 5-HT-induced Ca(2+) response was extremely inhibited. The results for the 5-HT-induced Na(+) current by the whole cell patch-clamp technique were as follows, (1) The 5-HT-induced Na(+) current in differentiated cells was significantly larger than that in undifferentiated cells; (2) The ED(50) value for 5-HT-induced Na(+) current in undifferentiated and differentiated cells was almost the same, about 4 x 10(-6) M each other; (3) The 5-HT-induced Na(+) current was completely blocked by 3 x 10(-9) M tropisetron, but not by other 5-HT receptor antagonists and 10(-7) M TTX. These results suggested that 5-HT-induced Ca(2+) response in differentiated NG cells was mainly due to L-type voltage-gated Ca(2+) channels allowing extracellular Na(+) to enter via 5-HT(3) receptors, but not through voltage-gated Na(+) channels.
  • Effects of some beta-adrenoceptor antagonists on orthostatic hypotension in repeatedly cold-(SART-) stressed rats, Yoshinori Funakami, Taeko Hata, Eiji Itoh, Seigo Itano, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 30(2), 303 - 308, Feb. 2007 , Refereed
    Summary:Rats stressed by specific alternation of rhythm in temperature (SART) show various symptoms of disautonomia, increased pulse rates, continuous hypotension, and severe orthostatic hypotension (OH) when they are subjected to postural change. The OH symptoms are improved by muscarinic M-2-receptor blockers. In the present study, effects of beta-adrenoceptor blocking agents on OH in SART-stressed rats were investigated. Anesthetized rats were restrained on a board in the supine position, and direct blood pressure and ECG were measured automatically using Fluclet (R) Jr.2. Postural change was performed by raising the rat's head up to a 60 degrees angle for 4 min. Unstressed rats treated with hexamethonium showed large decrease in blood pressure, small reflex from the bottom of pressure and decreased tachycardia reflex, whereas isoproterenol showed little changes. In SART-stressed rats, isoproterenol alleviated the decrease in blood pressure in postural change, brought large reflex from the bottom of pressure and increased tachycardia reflex, whereas hexamethonium had little changes. Propranolol and atenolol induced the similar changes as those seen by hexamethonium. ICI-118,551, a selective beta(2)-adrenoceptor antagonist showed large reflex from the bottom of pressure and increased tachycardia reflex in stressed rats, whereas little changes in unstressed rats. In conclusion, it was suggested that the hypotension in OH manifestation time of rats reflects the state of peripheral blood vessels, and beta(1)-adrenoceptors played a role in compensatory tachycardia reflex and beta(2)-adrenoceptors in blood pressure reflex. The circulatory regulation in SART-stressed rats seems to be poorly functioning in nervous reflex in postural changes.
  • Effects of AF-DX116 and other muscarinic receptor antagonists on orthostatic hypotension in autonomic imbalanced (SART-Stressed) rats, T Hata, Y Funakami, E Itoh, JOURNAL OF PHARMACOLOGICAL SCIENCES, JOURNAL OF PHARMACOLOGICAL SCIENCES, 97(3), 386 - 392, Mar. 2005 , Refereed
    Summary:SART (specific alternation of rhythm in temperature)-stressed rats are an animal model of autonomic imbalance created by exposing animals to repeated cold stress. The SART-stressed rats have been shown to easily develop orthostatic hypotension (OH). In this study, effects of AF-DX116, a selective M-2 antagonist, and other muscarinic receptor antagonists on OH were investigated in SART-stressed and unstressed rats. Each anesthetized rat was canulated into the left common carotid artery, and blood pressure (BP) and heart rate were measured. Stimulation for postural change was initiated by head-up tilting. As the indices of OH, the maximum fall of BP, % reflex (recovery from maximum fall), and the area enclosed between the baseline and the recovery Curve for BP (AUC) were used. Large AUC and small % reflex in SART-stressed rats were changed, becoming similar to those of the unstressed rats by AF-DX116 and methoctoramine. Atropine and methylatropine had similar effects to AF-DX116. However, the effects of methoctoramine, atropine, and methylatropine were less than that of AF-DX116. Pirenzepine was not effective. In conclusion, it was suggested in SART-stressed rats that OH was related to hyperactivity in the parasympathetic nerve and the M2 receptor played the major role in OH.
  • A role for corticotropin-releasing factor in repeated cold stress-induced anxiety-like behavior during forced swimming and elevated plus-maze tests in mice, H Nishikawa, T Hata, E Itoh, Y Funakami, BIOLOGICAL & PHARMACEUTICAL BULLETIN, BIOLOGICAL & PHARMACEUTICAL BULLETIN, 27(3), 352 - 356, Mar. 2004 , Refereed
    Summary:SART (specific alternation of rhythm in temperature) stress is known to cause anxiety-like behavior in mice/rats in several anxiety-related behavioral tests. In the present study, we investigated possible roles for corticotropin-releasing factor (CRF) and glucocorticoids in SART stress-induced anxiety-like behavior in two different anxiety-related behavioral tests. In the forced swimming test, CRF, administered intracerebroventricular (i.c.v.) at 0.5-2 pmol/mouse, dose-dependently reduced immobility time in unstressed and SART-stressed mice. alpha-Helical CRF, a specific CRIT receptor antagonist, administered i.c.v. at 0.1-1 nmol/mouse, dose-dependently increased immobility time in SART-stressed mice, but not in unstressed mice. In the elevated plus-maze test, CRF at 10-20 pmol/mouse significantly decreased the time spent in open arms in unstressed mice. CRF at a high dose tended to decrease this time in SART-stressed mice, but this decrease was not statistically significant. alpha-Helical CRIT failed to modify the time in unstressed mice. In contrast, alpha-helical CRF at 0.38 and 0.75 nmol/mouse increased the time in SART-stressed mice. Both immobility time in the forced swimming test and time spent in open arms in the elevated plus-maze test in unstressed and SART-stressed mice were unaffected by adrenalectomy. These results suggest that CRIT plays an important role in anxiety-like behavior caused by SART stress.
  • Blood pressure and heart rate are increased by AF-DX 116, a selective M-2 antagonist, in autonomic imbalanced and hypotensive rats caused by repeated cold stress, T Hata, E Itoh, Y Funakami, K Ishida, S Uchida, JAPANESE JOURNAL OF PHARMACOLOGY, JAPANESE JOURNAL OF PHARMACOLOGY, 85(3), 313 - 321, Mar. 2001 , Refereed
    Summary:Rats exposed to SART (specific alternation of rhythm in temperature) stress, which are ideal animal models for vagotonia-type dysautonomia, show various changes in cardiac and circulatory systems. In this study, attention was directed to cholinergic function in the SART-stressed rat heart and the effects of AF-DX 116, a specific muscarinic M-2 antagonist, on blood pressure and heart rate. The results were compared with those obtained for atropine and pirenzepine. In SART-stressed rats, systolic and diastolic blood pressures (SBP and DBP) were lower than in unstressed rats. Oral AF-DX 116 resulted in greater elevation of DBP than SEP in unstressed rats. In stressed rats, greater and more prolonged elevation of SEP than in unstressed rats was noted, particularly at higher doses. A dose-dependent SEP change in stressed rats, caused by intravenous AF-DX 116, was shifted upward in parallel with that in unstressed groups, unlike with oral administration The positive chronotropic effect of this drug was smaller in stressed rats than in unstressed rats, in contrast to the presser effect. SART-stressed rats may thus have an enhanced sympathetic tone in the heart, as well as changes in muscarinic M-2 receptors at sympathetic nerve endings and at the heart muscle. The effects of AF-DX 116 on blood pressure and heart rate thus may arise from peripheral action and AF-DX 116 may be useful for treating hypotension related to autonomic imbalance of the vagotonia type.

    Summary:<p>We investigated the preventive effect of extract containing metabolic products of <i>Bacillus subtilis natto</i> (NFE extract) on essential hypertension. The spontaneously hypertensive rat (SHR rat) and stroke-prone SHR rat (SHR-SP rat) were used in this study, and the NFE extract was administered by free drinking for 6-14 weeks of age (6, 7 weeks of age, 25 mL/day/rat; 8-14 weeks of age, 30 mL/day/rat). The administration of NFE extract did not affect the food intake and body weight in the WKY, SHR and SHR-SP rats. Significant changes in systolic (SBP) and diastolic (DBP) blood pressure levels between WKY rats administered with and without NFE extract were not observed for rats 6-14 weeks of age. On the other hand, the SBP and DBP in SHR and SHR-SP rats increased with aging, and the administration of NFE extract significantly attenuated the increased SBP, DBP in SHR and SHR-SP rats. In conclusion, the administration of NFE extract prevents increased blood pressure in SHR and SHR-SP rats. These findings provide significant information that can be used to design further studies aimed at elucidating the precise mechanism for decrease of blood pressure by NFE extract.</p>

    Summary:シスプラチン(CDDP)を含む化学療法の副作用として、高頻度に吃逆が生じることが知られている。その危険因子としては、CDDP投与量、制吐剤や性別など様々な因子が報告されている。しかし、制吐薬適正使用ガイドライン(以下、ガイドライン)に推奨されている、アプレピタント(APR)、セロトニン3(5-HT3)受容体拮抗薬、ならびにデキサメタゾン(DEX)の3剤併用療法(以下、3剤併用療法)施行時の吃逆発現因子についての統一された見解は得られていない。本研究では、CDDPを含む化学療法を受けた患者229例についてクラスター分析を行い、対象を系統分けすることで、3剤併用療法施行時に伴う吃逆の発現因子について調査した。また、ガイドライン制定前の高用量DEXと5-HT3受容体拮抗薬による制吐療法(以下、2剤併用療法)施行時と3剤併用療法施行時との吃逆発現率ならびに制吐効果について比較・検討を行った。その結果、高用量CDDP(≧70mg/m2)投与患者における吃逆発現率は、3剤併用療法施行時が2剤併用療法施行時に比べ低かった。一方、制吐効果については、3剤併用療法が2剤併用療法に比べ高かった。本研究から、高用量CDDP投与時においてガイドラインに推奨されている3剤併用療法施行時のAPR併用は、吃逆発現に影響しないことが示唆された。また、制吐療法として3剤併用療法は2剤併用療法よりも有効であることが示された。(著者抄録)

    Summary:Various kinds of stress affect our health in the mind and body. In this paper, hypotension and orthostatic hypotension(OH), especially influence of stress on OH are introduced. Differing from acute stress-induced hypertension, SART(specific alternation of rhythm in temperature) stress, a kind of repeated cold stress, causes hypotension in experimental animals. The stressed animals are in a state of autonomic imbalance. OH is easily and highly elicited under the stress by postural change. Four types of OH observed in the stressed rats resemble the types of OH observed on human in the patterns of blood pressure change. The OH was improved by treatment with muscarinic M_2 receptor antagonists differently from M_1 antagonists with no or anti effects. These results show that manifestation of the SART stress-induced OH is associated greatly with parasympathetic nerve, and that the SART-stressed rats are useful for elucidation of a mechanism of OH, and development of medication.

    Summary:反復低温負荷により作製され,vagotonia型自律神経失調症のモデル動物であり,低血圧・頻脈状態にあるSART(specific alternation of rhythm in temperature)ストレスラットを用いて,ストレスと起立性低血圧の関係をHead-up tilt試験により調べた.SARTストレスラットでは麻酔下でも意識下と同様,収縮期,拡張期血圧ともに低く,心拍数の多いことが認められた.このラットを麻酔下で背位固定し,急速に水平位から頭部を上昇し60°傾斜にする体位変換刺激を与えて低血圧を起こし,その状態を4分間持続した.このときにみられる血圧変化から,3つの指標を算出して,起立性低血圧の程度を正常ラット(非ストレス群)と比較した.SARTストレス群では,起立(60°head-up)による血圧の最大低下値が大きく,血圧上昇の反射率は有意に小さく,時間-血圧曲線-基線下面積は有意に大きかった.起立後の心拍数は非ストレス群では直後から増大したが,SARTストレス群では変化しないか,逆に減少した.このようにSARTストレスラットは体位変換によって容易にかつ重篤な起立性低血圧を惹起することが認められた.このような結果から,SARTストレスラットは起立性低血圧の実験動物モデルとしての有用な可能性を秘めていると考えられる(著者抄録)

  • Ministry of Education, Culture, Sports, Science and Technology, Grants-in-Aid for Scientific Research(若手研究(B)), A basic research in relation to stress and hypotension, The SART (specific alternation of rhythm in temperature)-stressed rat, which is a model animal of autonomic imbalance, is associated with low blood pressure and tachycardia under both consciousness and anesthesia. Additionally, orthostatic hypotension (OH) is developed easily by postural manipulation of SART-stressed rats. Accordingly, we studied the influence of the adrenalin α1 receptor agonist phenylephrine on stress-induced OH. In SART-stressed rats, prolonged intravenous administration of phenylephrine reduced OH. Sympathetic dysfunction is suggested to be a factor underlying SART stress-induced OH.
