Effect of JPHSKL on the quantity of 5-Hydroxytryptamine of colonic mucosa of diarrhea-predominant irritable bowel syndrome rats / 重庆医学

ABSTRACT

Objective To observe the effect of Jian Pi Hua Shi Ke Li(JPHSKL) on IBS‐D ,gastrointestinal peptide hormones of rats 5‐HT ,and explore the therapeutic mechanism .Methods 60 clean‐level Wistar rats were used in the experiment .The rats were randomly divided into normal group ,model group ,JPHS low ,middle ,high and Deshute group(10 rats in each group) .Used gavage senna and restraint stress to establish D‐IBS rat model .The drug contrations of JPHSKL low ,midle ,high group were 1 .5 ,2 .5 ,4 .0 g/mL ,3 mg/mol in Deshute group .Once each day ,for 2 weeks ,the other groups were nomol group without any treatment and mod‐el group which building successful .Immunohistochemical SABC method to observe 5‐HT level of colonic specimens .Results The 5‐HT level in colonic tissue of the rats in IBS‐D model were obviously higher than the nomal group(P0 .05) .Conclusion JPHSKL can im‐prove gastrointestinal function of IBS‐D model rats ,effect mechanism is relating to decrease the level of 5‐HT in colonic mucosa .
