Résumé
Objective To observe the effectof Invigorating Spleen and Eliminating DampnesGranuleon calcitonin gene related peptide(CGRP) in ramodelof diarrhepredominanirritable bowel syndrome (D-IBS) .Method60 Wistaratwere ran-domly divided into the control group(n=10) and the constructing model group (n=50) .Then ,the constructing model group warandomly re-divided into the model group (n= 10) ,positive control group (n= 10) ,invigorating spleen and eliminating dampnesGranulelow ,middle and high dose groups(n=10 each) .The D-Ibramodel waestablished by the restrainstresstimulation and gavage of folium sennae decoction fo2 week.The expression of CGRP in small intestinal mucosal membrane in each group wadetected by the immunohistochemical method .ResultIn the model group ,the CGRP positive arewadecreased ,which showed the statistical difference compared with the control group (P＜0 .05);the CGRP positive arein varioutreatmengroupwaincreased ,which showed the statistical difference compared with the model group (P＜0 .05);in the invigorating spleen and e-liminating dampnesgranulemiddle and low dose group,the CGRP positive arewaincreased with the statistical difference com-pared with the positive control group (P＜0 .05) ,while withouthe statistical difference compared with the invigorating spleen and eliminating dampnesgranulehigh dose group (P＞0 .05) .Conclusion Invigorating spleen and eliminating dampnesgranulea-chievethe therapeutical effecby increasing the level of CGRP in local intestinal tissue .
