摘要: 目的: 研究中药香加皮水提取物(cortex periplocae extract,CPE) 对小鼠免疫功能的调节作用。 方法: 无菌分离小鼠淋巴细胞,与不同浓度CPE(250、125、64、32、16、8 μg/ml)共同培养一定时间后,采用MTT法测定其对刀豆素A(ConA)诱导的小鼠淋巴细胞转化能力的影响,采用LDH酶释放法测定对NK细胞杀伤活性的影响;采用对肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)敏感的L929细胞,使用生物法测定CPE对单核细胞产生TNF-α的影响。各实验均设对照组。 结果: CPE在8~64 μg/ml的浓度范围内可不同程度的提高小鼠体外淋巴细胞转化率和NK细胞杀伤活性,以及促进单核细胞分泌TNF-α,与对照组比较差异均具有统计学意义(P均<0.05)。 结论: 一定剂量的CPE可以提高小鼠淋巴细胞的免疫功能,从而发挥抗肿瘤作用。

Abstract: OBJECTIVE: Study on the immunoregulatory function of cortex periplocae extract(CPE) on mice lymphocytes. METHODS: We separated mice lymphocytes with aseptic manipulation and cultivated them with CPE(concentrations were 250,125,64,32,16,8 μg/ml), Then the effect of CPE on the proliferative activity of mice lymphocytes induced by ConA was measured by using MTT method. The activity of NK cells was assayed by a released LDH assay. The content of tumor necrosis factor-α(TNF-α) was evaluated by biological method. RESULTS: CPE within the range of 8 to 64 μg/ml could markedly stimulate the mice lymphocyte to proliferate and enhance the activity of NK cells. It stimulated monocytes to produce TNF-α as well. CONCLUSION: CPE showed immunoregulatory activity on mice lymphocytes. This could be used clinically for modulating immune response or for treating tumors and other diseases.
