羧甲基茯苓多糖(CMPM)是茯苓多糖的一种衍生物,具有明显抑制肿瘤生长的作用。本文报道了用酶释放法观察CMPM对健康人外周血NK细胞活性的影响,发现100μg/ml的CMPM对NK细胞活性育促进作用,提示这可能是其增强免疫功能从而抑制肿瘤的机制之一。同时,本文对酶释放法测定NK细胞活性可靠性的研究表明,本法稳定性较好。 Carboxymethylhydrazine polysaccharide (CMPM) is a derivative of Lycium barbarum polysaccharide and has a significant effect in inhibiting tumor growth. In this paper, the effect of CMPM on NK cell activity in peripheral blood of healthy people was observed by enzyme release method. It was found that 100 μg/ml CMPM promoted the activation of NK cells, suggesting that this may be one of the mechanisms that enhance the immune function and thereby inhibit tumors. At the same time, the study on the determination of the activity of NK cells by enzyme release method shows that this method has good stability.
