Study on role of Chengqi Shengxue prescription in anti-tumor and immunoregulation / 中国中药杂志

<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>

Evaluation on phytoestrogen effects of ten kinds of Chinese medicine including flos carthami / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the phytoestrogenic effects of ten kinds of Chinese medicine including flos carthami, radix cyathulae, radix salviae miltiorrhizae, fructus ligustri lucidi, fructus lycii, radix clycyrrhizae, herba cistanches, herba epimedii, fructus psoraleae and semen cuscutae.</p><p><b>METHOD</b>240 female Kunming mice weighting 9 - 12 g were randomly divided into two main groups A and B. A group was divided into 12 small groups: 1 solvent control group, 1 diethylstilbestrol control group and 10 Chinese medicine groups. B group was also divided into 12 small groups: 1 solvent control group, 1 diethylstilbestrol control group and 10 Chinese medicine antagonistic groups. Mice in ten antagonistic groups were administered both Chinese medicine and diethylstilbestrol everyday. After administered(op) for 4 days, blood was collected and serum was separated. The effect of the pharmacological serum on proliferation rate of MCF-7 (ER+) was analyzed by MTT-assay.</p><p><b>RESULT</b>In A group, proliferation rates of MCF-7 cells treated with serum from eight Chinese medicine groups including flos carthami, radix cyathulae, radix salviae miltiorrhizae, fructus lycii, herba cistanches, herba epimedii, fructus psoraleae and semen cuscutae were coued markedly increase respectively. While serum from fructus ligustri lucidi group could markedly decrease the proliferation rate of MCF-7 cells. In B group, the increased proliferation rate of MCF-7 cells caused by diethylstilbestrol was significantly reduced in seven Chinese medicine antagonistic groups including flos carthami, radix cyathulae, radix salviae miltiorrhizae, radix clycyrrhizae, herba epimedii, fructus psoraleae and semen cuscutae. While the increased proliferation rate could be markedly enhanced in herba cistanches group.</p><p><b>CONCLUSION</b>Six kinds of Chinese medicine such as flos carthami, radix cyathulae, radix salviae miltiorrhizae, herba epimedii, fructus psoraleae and semen cuscutae show both estrogenic effects (when administered indepently) and antiestrogenic effects (when administered together with diethylstilbestrol). Such bidirectional effects depends on the internal estrogen level.</p>
