Abstract:
OBJECTIVE:To study the effects of volatile oil of Pogostemon cablin on the expression of tight junction proteins ZO-1 and Occludin in colonic mucosal epithelial cells of rats with post-infectious irritable bowel syndrome(PI-IBS). METHODS:Rats were randomly divided into normal control group(distilled water),model group(distilled water),Trimebutine maleate tablet group(TMT,0.1 g/kg)and volatile oil of P. cablin low-dose,medium-dose and high-dose groups [2,3,4 g(crude drug)/kg] with 8 rats in each group. Except for normal control group,those groups were given colon perfusion of acetic acid to induce PI-IBS mod-el. After modeling,they were given relevant medicine intragastrically once a day for consecutive 5 days. The expression of ZO-1 and Occludin [by IOD] and their distribution were detected by immunohistochemistry. RESULTS:In normal control group,ZO-1 and Occludin evenly distributed on the top of enterocyte,manifesting as alveolate and punctiform;in model group,ZO-1 and Oc-cludin scattered on the top of enterocyte,showing uneven dyeing or fade;the distribution of ZO-1 and Occludin in volatile oil of P. cablin groups was similar to normal control group,and its dyeing was lighter than that of normal control group. IOD value of ZO-1 and Occludin in model group were lower than in normal control group(P<0.01);those of volatile oil of P. cablin high-dose group and the IOD value of ZO-1 of P. cablin medium-dose group and TMT group were higher than those of model group (P<0.05 or P<0.01). CONCLUSIONS:The volatile oil of P. cablin can up-regulate the expression of tight junction proteins ZO-1 and Occlu-din in colonic mucosal epithelial cells of rats with PI-IBS.
