[Changes of local vaginal immune regulation in rats infected with vulvovaginal candidiasis].
Objective: To study the disease process of vulvovaginal candidiasis (VVC) infection in rat model of VVC, and to study the immuno-repairing effect of different treatments on vaginal epithelium and the ultra-structural changes of vaginal epithelial cells. Methods: The VVC model of female rats were established. After successful modeling, the rats were treated with no treatment (model control group), nystatin and Kangfu Xiaoyan suppository. ⋯ Immunohistochemical staining showed, the expressions of IFN-γ and IgG in the four cytokines which played a protective role increased after Kangfu Xiaoyan suppository treatment, significantly different from that of model control group (P<0.05), but there were no significant differences of the IFN-γ and IgG expression between Kangfu Xiaoyan suppository group and those of nystatin group (P>0.05); the expression of IL-17 was increased after nystatin treatment, but decreased after Kangfu Xiaoyan suppository treatment, and the difference between the two groups had statistical significance (P<0.05). Conclusions: The ultrastructure of vaginal epithelial cells after VVC infection could be damaged obviously, the local immune state is disordered, and the antifungal drug nystatin has a good therapeutic effect on VVC, it could significantly repair the damaged vaginal epithelium structure after VVC infection and strengthen the protective immune function of vaginal epithelium. Kangfu Xiaoyan suppository, one of Chinese medicine, has similar therapeutic effect with nystatin.
