乌龙茶和茉莉花茶对小鼠免疫功能的影响

乌龙茶和茉莉花茶对小鼠的免疫功能试验结果表明,10%乌龙茶或茉莉花茶灌胃均能引起小鼠的胸腺缩小。1%花茶灌胃,小鼠的脾淋巴细胞自发性~3H-TdR掺入及 Con A 刺激的淋巴细胞转化率均明显增高,但乌龙茶与10%茉莉花茶则未见这种作用。10%乌龙茶能抑制小鼠SRBC溶血素抗体的产生,而花茶对抗体的产生影响不大。1%花茶可使小鼠外周血 ANAE 阳性细胞增多。此外,还对茶叶影响机体免疫功能的机理进行了讨论。

Effects of Oolong Tea and Jasmine Tea on Mouse lmmune Function

Effects of Oolong tea and jasmine tea on mouse immune function wereinvestigated.The weight of thymus in mouse decreasesd when 10% Oolongtea or jasmine tea was given by stomach tube.However,giving 1% jasm-ine tea by stomach tube enhanced the spontaneous uptake of H-TdR bymurine splenic lymphocytes or con A stimulated murine splenic lymohocytestransformation.The enhancement didn't occur when Oolong tea or 10%jasmine tea was given.The anti-SRBC antibody production of the mouse wassignificantly impaired by 10% Oolong tea,while jasmine tea had no signi-ficant effect on the antibody production.The percentage of ANAE positivelymphocyte in murine peripheral blood was significantly increased by10% jasmine tea.Results suggested that tea might have various effects onimmune function,depending upon the processing method and the concentra-tion of the tea used.
