摘要: 目的:研究竹叶黄酮对小鼠脾细胞的免疫作用。方法:采用分子免疫学、细胞生物学和分子生物学等多种技术评价了竹叶黄酮对小鼠的免疫增强作用。结果:在一定剂量范围内竹叶黄酮可促进小鼠脾脏细胞DNA和蛋白质的合成,促进了细胞的增殖,同时促进了小鼠脾细胞IFNγmRNA的表达,IFNγ的产生与分泌,IFNγ又反过来激活NK细胞,促进T、B细胞分化和CTL成熟,刺激B细胞分泌抗体。结论:一定剂量的竹叶黄酮能增强小鼠的免疫调节能力,并呈明显的剂量效应关系。

Abstract: Objective:Study on immunoregulation of flavonoids from the leaves(FBL)to spleen cells of rat.Methods:The immunities of FBL to spleen cells of rat were evaluated by means of molecule immunology,modern biology of cells and modern molecular biological technology.Results:FBL could hasten synthesization of DNA and protein of spleen cells of rat within a dosage range,accelerate cell proliferation as well as facilitate mRNA expression,exudation and produce of IFNγ.At the same time,IFNγ could activate NK cells,accelerate differentiation of T cells and B cells and maturation of CTL,and catalyze antibody exudation of B cells on the contrary.Conclusion:FBL could enhance immunoregulation function of rat in special dosage and presented typical dose-effect relationship.

Key words: flavonoids from bamboo leaves (FBL), immunoregulation, molecule mechanism, spleen cells
