目的比较四君子汤和理中汤对腹泻型IBS(D-IBS)大鼠胃肠转运功能、胃肠激素P物质(SP)、胆囊收缩素(CCK)的影响。方法受试动物按随机数字表法分为空白对照组(n=10)和模型组(n=60)。以番泻叶(0.4g/m L)煎剂按10 m L/kg容量灌胃并结合粗制...目的比较四君子汤和理中汤对腹泻型IBS(D-IBS)大鼠胃肠转运功能、胃肠激素P物质(SP)、胆囊收缩素(CCK)的影响。方法受试动物按随机数字表法分为空白对照组(n=10)和模型组(n=60)。以番泻叶(0.4g/m L)煎剂按10 m L/kg容量灌胃并结合粗制棉绳束缚大鼠两后肢的复合法建立D-IBS大鼠模型,造模成功后D-IBS大鼠随机分为3组,即模型组、四君子汤干预组、理中汤干预组,每组10只,四君子汤干预组和理中汤干预组每日剂量分别为四君子汤(20 g/kg)和理中汤(20 g/kg)干预后,通过测定各组大鼠胃肠转运功能、血清及小肠SP、CCK水平差异比较四君子汤和理中汤对D-IBS的干预效应。结果与空白组比较,D-IBS模型大鼠胃残留率和小肠推进率显著升高(P﹤0.01),血清及小肠CCK、SP水平均显著升高(P﹤0.01);经中药干预后,四君子汤和理中汤均能降低胃残留率和小肠推进率(P﹤0.05),降低血清及小肠CCK水平(P﹤0.05),四君子汤和理中汤组比较,以理中汤作用显著(P﹤0.05);在抑制SP表达方面,四君子汤和理中汤有降低血清SP水平的趋势,但四君子汤组与模型组比较组间差异无统计学意义(P﹥0.05),理中汤组与模型组比较组间差异有统计学意义(P﹤0.05);而且四君子汤和理中汤均能降低小肠组织SP水平(P﹤0.05),理中汤组与四君子汤比较以理中汤作用显著(P﹤0.05)。结论四君子汤和理中汤调节D-IBS大鼠胃肠转运功能和血清及小肠SP、CCK水平的作用相似,且理中汤调节作用优于四君子汤。展开更多
AIM:To study the relative efficacy of cisapride, metoclopramide,domperidone,erythromycin and mosapride on gastric emptying(GE)and small intestinal transit(SIT) in morphine treated mice. METHODS:Phenol red marker meal ...AIM:To study the relative efficacy of cisapride, metoclopramide,domperidone,erythromycin and mosapride on gastric emptying(GE)and small intestinal transit(SIT) in morphine treated mice. METHODS:Phenol red marker meal was employed to estimate GE and SIT in Swiss albino mice of either sex.The groups included were control,morphine 1 mg/kg(s.c.15 rain before test meal)alone or with(45 rain before test meal p.o.)cisapride 10 mg/kg,metoclopramide 20 mg/kg, domperidone 20 mg/kg,erythromycin 6 mg/kg and mosapride 20 mg/kg. RESULTS:Cisapride,metoclopramide and mosapride were effective in enhancing gastric emptying significantly(P<0.001) whereas other prokinetic agents failed to do so in normal mice.Metoclopramide completely reversed morphine induced delay in gastric emptying followed by mosapride. Metoclopramide alone was effective when given to normal mice in increasing the SIT.Cisapride,though it did not show any significant effect on SIT in normal mice,was able to reverse morphine induced delay in SIT significantly(P<0.001) followed by metoclopramide and mosapride. CONCLUSION:Metoclopramide and cisapride are most effective in reversing morphine-induced delay in gastric emptying and small intestinal transit in mice respectively.展开更多
