舒肝丸抗实验性胃溃疡的作用

目的　研究舒肝丸抗实验性胃溃疡的作用及其机制。方法　采用小鼠水浸应激性、利血平性及无水乙醇性胃溃疡模型观察舒肝丸对胃溃疡的保护作用 ;幽门结扎收集胃液观察其对大鼠胃液分泌的影响 ;采用小鼠胃排空方法观察舒肝丸对胃运动的影响 ;以热板法和扭体法观察其镇痛作用。结果　舒肝丸对小鼠水浸应激性、利血平性及无水乙醇性胃溃疡模型均有明显的保护作用 ;能抑制大鼠胃酸及胃蛋白酶的分泌 ,促进胃黏液的分泌 ;抑制正常小鼠胃排空及新斯的明所致的胃排空亢进 ,对阿托品所致的胃排空迟缓有协同作用 ,但作用不明显 ;可提高小鼠的热痛阈 ,减少小鼠的扭体次数。结论　舒肝丸具有抗实验性胃溃疡的作用。该作用可能与其抑制胃液分泌、促进胃黏液分泌、抑制胃平滑肌运动及镇痛作用有关

The action of Shuganwan on experimental gastric ulcer

Objective To study the action of Shuganwan(SHGW) on experimental gastric ulcer in mice. Methods The anti-ga stric ulcer action of SHGW was observed on the gastric ulcer induced by water im mersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secr etion in rats was studied by pyloric ligation. The effect on gastrointestinal mo tility was observed by gastric emptying in mice. The analgesic effect was tested by the hot-plate test and writhing method. Results SHGW m arkedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGW significantly inhibited the secretion of gastric a cid and pepsin and promoted the secretion of gastric mucus. SHGW markedly delaye d gastric emptying in normal mice and when gastric emptying was stimulated by ne ostigmine. SHGW mildly strengthend the effect of atropine on gastric emptying. S HGW enhanced hot pain threshold and decreased the number of twisting body in mic e. Conclusion Shuganwan may have anti-gastric ulcer ac tion. The mechanism of the action might be associated with its inhibition of the secretion of gastric juice, promotion of the secretion of gastric mucus,inhibit ion of activity of gastric smooth muscle and analgetic effect.
