胃肠舒的药理作用研究

目的:探讨胃肠舒(黄连、吴茱萸等)在调节胃肠功能、保护胃黏膜、止痛、止泻方面的药理作用.方法:观察本品对正常及新斯的明所致小鼠小肠运动亢进和胃排空影响;对无水乙醇诱发大鼠胃溃疡的影响;对大鼠胃液分泌的影响;对蓖麻油所致腹泻的影响;对醋酸诱发疼痛的影响;对大鼠小肠吸收功能的影响.结果:胃肠舒对正常小鼠肠推进无明显影响,对机能亢进小鼠小肠推进有抑制作用;本品可抑制胃排空;抑制胃液分泌;降低胃液酸度和胃蛋白酶活性;对无水乙醇诱发的胃黏膜损伤有明显的保护作用;减少扭体次数,使小鼠累计稀便次数减少,小肠吸收减弱.结论:本品具有使机能紊乱的胃肠功能恢复正常、减轻胃黏膜损伤及止痛止泻的作用.

Study on pharmacological action of Weichangshu

AIM: To study the pharmacological effect of Weichangshu (WCS) (Rhizoma coptidis, Fructus Evodiae., etc.) on rodent gastrointestinal function and gastric mucosa, and to analyze its analgesic and antidiarrheal mechanism. METHOD: Mouse's hypermobility induced by neostigmine and its gastric emptying were treated by WCS in comparison with normal subjects, rat's gastric ulcer induced by absolute ethanol, diarrhea induced by castor oil, pain induced by acetic acid and rat's gastric secretion and absorption were observed. RESULTS: The experimental results showed that WCS did not affect normal mouse's intestinal propulsion but significantly antagonized neostigmine induced intestinal propulsion and inhibited the gastric mucosa injure and decreased the frequency of the writhe and limited diarrhea. CONCLUSION: WCS has power to recover gastrointestinal function and lessen gastric mucosa injury and has analgesic and antidiarrheal effect.
