[目的 ]观察从藤茶中提取出的一单体化合物 APS对正常小鼠淋巴细胞增殖反应的影响。 [方法 ]利用同位素〔3 H〕 - Td R掺入法 ,测定小鼠淋巴细胞增殖反应的强度。 [结果 ]APS中、大剂量组与阳性对照组比较有显著性差异 ,增强率分别为 1 5 .2 %、 2 6.8%、 5 9.6%。 [结论 ]APS对 Con A诱导的小鼠淋巴细胞增殖有增强作用 ,具有明显的免疫增强作用 [Objective] To observe the effect of APS, a monomer compound extracted from vine tea, on the proliferation of normal mouse lymphocytes. [Methods] The isotope [3 H]-Td R incorporation method was used to determine the intensity of lymphocyte proliferation in mice. [Results] There were significant differences between the APS medium and large dose groups and the positive control group, with the enhancement rates of 15.2%, 2 6.8%, and 5 9.6%, respectively. [Conclusion] APS enhances the proliferation of mouse lymphocytes induced by Con A and has obvious immunopotentiation.
