【摘要】 本文采用 MTT法观察螺旋藻粗粉及提取物对 CTL L细胞和正常 BALB/ c小鼠脾细胞分泌 IL - 2的影响。实验结果表明 ,所用的螺旋藻的 3个组份在实验浓度范围内对 CTLL细胞无增殖活化作用、螺旋藻粗粉及提取物多糖、藻兰蛋白 1、0 .1和 0 .0 1g· L-1浓度时均对正常小鼠脾细胞分泌 IL - 2有促进作用 ,藻兰蛋白部分作用最强 ,其它提取物作用次之 ,在上述浓度范围内 IL - 2分泌水平有剂量依赖关系。高浓度 (1g· L-1)粗粉及提取物具有协同 Con A(2 mg· L-1)刺激小鼠脾细胞分泌 IL - 2的作用更多还原

【Abstract】 It has been shown that Spirulina platensis can regulate imminological functions.We report here that crude extract and purified components (phycocyanin and polysaccharide) from Spirulina platensis can induce secretion of IL 2 in splenocyte of BALB/C mice by means of MTT method.In the present study,we showed that all experimental components can’t enhance proliferation of CTLL which was used in MTT method,but induce IL 2 secretion in splenocyte of BALB/C mice in three different concentration (0.01,0.1,1 g·L -1 ).Indeed the purified components especially phycocyanin part showed stronger IL 2 inducing activity than the crude one.IL 2 level was grow up when the incubation time of splenocyte and Spirulina platensis increased.In the concentration of 1 g·L -1 ,detected Spirulina platensis in our study assist IL 2 inducing of ConA (2mg·L -1 ) in splenocyte of BALB/C mice.更多还原
