加味增液汤对复方地芬诺酯诱导的便秘小鼠的影响

目的: 考察在增液汤（包括玄参、生地、麦冬）基础上增加铁皮石斛和/或生白术对复方地芬诺酯诱导的便秘小鼠的影响。方法: 采用复方地芬诺酯建立小鼠便秘模型，制备增液汤+生白术+铁皮石斛、生白术+增液汤、增液汤水煎液及麻仁胶囊溶解液，分别灌胃给药后检测便秘小鼠排便、小肠推进情况及血清超氧化物歧化酶（SOD）活力。结果: 增液汤+生白术+铁皮石斛与生白术+增液汤促进排便及小肠推进的疗效优于增液汤及麻仁胶囊溶解液；增液汤+生白术+铁皮石斛可显著提高便秘小鼠血清SOD活力，优于增液汤及麻仁胶囊溶解液。结论: 生白术（或生白术+铁皮石斛）可增强增液汤对复方地芬诺酯诱导的小鼠便秘的疗效，铁皮石斛+生白术+增液汤可提高便秘小鼠血清SOD活力。

Effects of Jiawei Zengye decoction on diphenoxylate-induced constipation in mice

AIM: To study the effect of dendrobii officmalis caulis (DOC) and/or atractylodismacrocephalaerhizoma (AMR) based on Zengyedecoction (ZYD), including scrophulariaeradix, rehmanniaeradix, ophiopogonisradix on diphenoxylate-induced constipation in mice. METHODS: Diphenoxylate was used to establish the mouse model of constipation, the decoction of DOC+AMR+ZYD, AMR+ZYD and ZYD, the dissolving liquid of Maren capsule (MRC) were prepared, after the gavage administration of them respectively, the defecation, small intestine propulsion and serum SOD activity in constipated mice were detected.RESULTS:The efficacy of promoting defecation and small intestine propulsion by DOC+AMR+ZYD and AMR+ZYD was better than that of ZYD and MRC; DOC+AMR+ZYD significantly increased serum SOD activity in constipated mice and the efficacywas superior to ZYD and MRC. CONCLUSION:DOC+AMR and AMR enhanced ZYD efficacy on diphenoxylate-induced constipation in mice,DOC+AMR+ZYD elevated the constipated mice serum SOD activity.
