丁桂儿脐贴对功能性消化不良大鼠和脾虚小鼠的影响

目的:观察丁桂儿脐贴对功能性消化不良大鼠(FD)和脾虚小鼠的影响,探讨其可能的作用机制.方法:采用不规则进食加稀酸喂养制作大鼠FD模型,连续给药14 d后,测定大鼠的体重、血清一氧化氮(NO)、胆碱酯酶(AChE)及胃窦部肥大细胞(MC).采用大黄造成脾虚小鼠模型观察其对胃排空的影响.结果:与模型组相比,丁桂儿脐贴各剂量组体重显著增加(P＜0.05)、丁桂儿脐贴中剂量组(含生药量1.34 g· kg-1)大鼠胃蛋白酶活性明显升高、丁桂儿脐贴高剂量组(含生药量2.67 g·kg-1)大鼠血清NO和胃窦部肥大细胞数显著降低(P＜0.05)、血清AChE含量显著升高.丁桂儿脐贴使脾虚小鼠体重显著增加,胃排空加速,改善脾虚小鼠症状.结论:丁桂儿脐贴对功能性消化不良有明显的改善作用,可显著降低血清NO、升高血清AChE和降低胃窦部肥大细胞数,可能是其治疗FD的机制.

Effect of Dingguier umbilical paste on rats with functional dyspepsia and mice with splenic asthenia

Objective: To observe the effect of Dingguier umbilical paste on rats with functional dyspepsia and mice with splenic asthenia, and investigate the related mechanism. Method: Functional dyspepsia models of rats were made by irregular food intake plus diluted hydrochloric acid. Successional treatments were offered for 14 days. The rats weights, contents of serum NO, AChE and MC were measured. The rats with splenic asthenia were made by rhubarb feed, and observed the affection of gastric emptying. Result: Compared with those in the model control group, the weight of rats in all dosages Dingguier umbilical paste groups increased obviously (P<0.05), pepsin activity of rats in the dosage (1.34 g·kg^-1) Dingguier umbilical paste groups was significantly higher and the contents of NO and quantities of MC in the dosage (2.67 g·kg^-1) Dingguier umbilical paste groups decreased clearly (P<0.05), and the contents of serum AChE in all dosages Dingguier umbilical paste groups rose apparently. The weight of mice with splenic asthenia increased obviously, accelerated gastric emptying, and improved the symptom. Conclusion: Dingguier umbilical paste has significant improvement of indigestion. The related mechanism may be to reduce the content of serum NO and the quantity of MC and enhance the content of serum AChE.
