The Protection of Chaishao Chengqi decoction to Intestinal Mucosal Barrier in Rats with severe acute pancreatitis

Abstract

Objective To observe the protection of Chaishao Chengqi decoction to the intestinal mucosal barrier in rats with severe acute pancreatitis.Methods 72 SD rats were randomly divided into normal control group,SAP group and Chaishao Chengqi decoction therapeutic group.10%L-arginine was injected into the rats abdominal to establish SAP models. Chaishao Chengqi decoction 1ml.kg-1 was injected into the rats' stomach of therapeutic group and repeated injections were given per 6 hours until the rats were executed. Normal control group and SAP group were given isodose stroke-physiological saline solution. Specimens were get at 6,12,24 and 48h for detections:①Pathological change of pancreas and Ileal mucous membrane;②Apoptotic index of Ileal mucous membrane;③TNF-α contents of blood serum. Results Apoptotic index of Ileal mucous membrane in SAP group was significantly higher than Normal control group and therapeutic group(P＜0.05);TNF-α contents of SAP group was significantly higher than normal control group and theraroup(P＜0.05);Pathological lesion of pancreas and Ileal mucous membrane of therapeutic group was slighter than SAP group.Conclusions Our experiment suggested that excessus apoptosis of intestinal mucosa was one of the main mechanisms of mucosal barrier function disorder in SAP. Chaishao Chengqi decoction has a protective effect on the intestinal mucosal barrier function. Key words: Severe acute pancreatitis ; Intestinal mucosal barrier ; Chaishao Chengqi decoction ;
