5类茶叶对ConA刺激的小鼠脾淋巴细胞^3H—TdR掺入的影响

Effect of Five Sorts of Tea on the Uptaking of 3H-TdR by ConA Stimulated Splenic Lymphocyte of Mice

研究了5类茶对 ConA 刺激的小鼠脾淋巴细胞~3H-TdR 掺入的影响。结果表明,用2%的茉莉花茶、绿茶、红茶和白茶灌胃,均能显著促进 ConA 刺激的正常和血虚小鼠脾淋巴细胞转化,但乌龙茶的促进作用不显著。对不同浓度 ConA 刺激的正常和血虚小鼠脾淋巴细胞的增殖反应,2%的茉莉花茶、绿茶、红茶和白茶也分别高于对照组。小鼠脾淋巴细胞活化所需的最适 ConA 浓度,健康小鼠为12.5μg/ml(绿茶、红茶和白茶)和17.5μg/ml(茉莉花茶),血虚小鼠为22.5μg/ml。上述结果表明,2%的茉莉花茶、绿茶、红茶和白茶均能显著增强或改善正常和血虚小鼠的细胞免疫功能。

Effect of five sorts of tea on the uptaking of ~3H-TdR by ConA stimu-lated splenic lymphocytes of mice were investigated.Results indicated that2% jasmine tea,green tea,black tea,or white tea given by stomachtube could significantly enhanced ConA stimulated healthy and blood-deficentroutine splenic lymphocyte transformation.The enhancement didn't occurwhen,2% Oolong tea was given.The proliferative response of routinesplenic lymphocytes stimulated by various concentration ConA were alsomarkedly higher than those of control groups respectively.In healthy mice,optimum concentrations of ConA stimulated mutine splenic lymphoeytetransformation were 12.5 μg/ml(green tea,black tea and white tea)and17.5 μg/ml(jasmine tea).In mice with blood-deficiency,optimum concen-tration was 22.5 μg/ml.Results indicated that 2% jasmine tea,green tea,black tea and white tea infusions could remarkably increased or improved thecell immunity in healthy and blood-deficientmice.
