胃痛消痞方对脾胃虚寒型功能性消化不良大鼠胃肠动力和胃动素的影响

目的:观察胃痛消痞方对功能性消化不良(FD)大鼠胃肠动力、血浆胃动素(MOT)的影响.方法:将66只大鼠以食醋灌胃建立FD模型,随机分为空白组、模型组、中药(低、中、高)剂量组、多潘立酮组;分别用生理盐水、不同浓度的胃痛消痞方、多潘立酮,每日2次灌胃治疗14 d:观测各组大鼠血浆MOT水平、小肠推进比、胃内排空率.结果:与模型组比较,各浓度胃痛消痞方均能明显提高血浆MOT含量、提高小肠推进比,差异有统计学意义(MOT含量:104.57 pmol/L±14.05 pmol/L,124.90 pmol/L±15.21 pmol/L,125.84 pmol/L±27.67 pmol/L vs 81.95 pmol/L±12.02 pmol/L,P<0.01;小肠推进比:55.62%±2.92%,56.91%±4.65%.59.04%±3.24%vs 51.80%±3.57%,P<0.01),空白组、中药中、高剂量组之间小肠推进比无明显差异(P>0.05),但均高于多潘立酮组(P<0.01);能提高胃排空率,与多潘立酮组无统计学差异(P>0.05).结论:胃痛消痞方能通过提高血浆中MOT水平,从而促进脾胃虚寒型FD大鼠的胃肠动力.

Influence of Weitongxiaopi Decoction on gastrointestinal motility and plasma motilin levels in rats with functional dyspepsia caused by spleen- stomach deficiency-cold

AIM: To observe the impact of Weitongxiaopi (WTXP) Decoction on gastrointestinal motility and plasma motilin levels in rats with functional dyspepsia ( FD ) duetosplen - stomach deficiency-cold. METHODS: FD was induced in 66 rats by giving vinegar. The rats were then randomly divided into six groups: normal control group, model control group, low-dose WTXP Decoction group, medium-dose WTXP Decoction group, highdose WTXP Decoction group and domperidonegroup. The latter five groups were given normal saline, d...
