ABSTRACT
<p><b>OBJECTIVE</b>To investigate the role of Chengqi Shengxue prescription in anti-tumor and immunoregulation and to evaluate its effect on apoptosis and T lymphocyte subsets of tumor-bearing mice.</p><p><b>METHOD</b>S180 ascites tumor and Lewis lung carcinoma tumor-bearing mice were used in the screening. Then 55 mice were treated randomly with the model, cyclophosphamide (30 mg x kg(-1)), or three different dosages of Chengqi Shengxue prescription (2. 4, 1.2, 0.6 g x kg(-1). After the treatment apoptosis of tumor cell and peripheral T lymphocyte subsets of tumor-bearing mice was analyzed by flow cytometry.</p><p><b>RESULT</b>Lewis lung carcinoma was a nsitive tumor cell line to Chengqi Shengxue prescription. Compared with the model group, significantly increased apoptosis was observed after administration of high and medium dose of Chengqi Shengxue prescription (P < 0. 05) by PI staining. Increased early apoptosis in cancer cells was observed in all experimental doses of Chengqi Shengxue prescription by Annexin V and PI double staining (P < 0.01) . The analysis of T lymphocyte subsets showed that the percentage of CD3, CD4 and CD4/CD8 ratio decreased significantly in model group when compared with the normal ones (P < 0.01), while no change was observed in CD8. In administration groups, CD3, CD4 and CD8 were significantly lower than normal ones (P < 0.01) , but CD4/CD8 ratio did not change significantly.</p><p><b>CONCLUSION</b>Chengqi Shengxue prescription has selectively inhibitive effect on the growth of mouse Lewis lung carcinoma and takes an antitransfer role. Its anti-tumor effect may be owing to inducing tumor cell apoptosis. Chengqi Shengxue prescription improves cellular immune function through enhancing CD4/CD8 ratio.</p>
