    Abstract:
    OBJECTIVE: To investigate the effect of Jianpi Yiqi Qingyou decoction on lymphocyte subsets and IL-2 mRNA in gastric tissue in rats with chronic superficial gastritis. METHOD: Wistar rats were randomly divided into 6 groups (11 for each): a blank control groups, the model of the control groups, the treatment groups (low-dose groups of traditional Chinese medicine, moderate-dose groups of traditional Chinese medicine, high-dose groups of traditional Chinese medicine) and lansoprazole groups. The models were made with the method in reference except a blank control groups. These rats are drinking freely with 0. 02% ammonia, continuous 90 days, and made preparations for experimental animal model of superficial gastritis. Making the model were detected by HE dying. The count of CD3+, CD4+ and CD8+ T cells were detected by immunohistochemistry. Using reverse transcriptase polymerase chain reaction (RT-PCR), the expression levels of IL-2 mRNA in gastric tissue were quantified. RESULT: Compared with that in model groups, the content of CD3+ T cells and CD4+ T cells in gastric tissue obviously increased in high dose of traditional Chinese medicine groups , the content of CD8+ T cells in gastric tissue obviously decreased in high dose of traditional Chinese medicine groups and the difference was significant (P < 0.01). The expression levels of IL-2 mRNA in gastric tissue obviously increased in moderate and high doses of traditional Chinese medicine groups, and the difference was significant compared with that in model group (P < 0.01). CONCLUSION: Jianpi Yiqi Qingyou decoction can obviously improve the content of CD3+ T cells and CD4+ T cells and the expression levels of IL-2 mRNA, decrease the content of CD8+ T cells in gastric tissue, improve immunity of rats. So the research results can provide some evidences for the treatment for chronic superficial gastritis.
