为了研究给予补中益气汤的时间长短引起的作用差异,以给药32周及1周的小鼠脾脏NK细胞的YAC-1细胞为靶点,探讨了细胞毒性以及脾脏的NK细胞数和CD4/CD8的比值。结果,给予补中益气汤32周,脾脏NK细胞的细胞毒性轻度增强,而给药1周呈明显增强。NK细胞数和CD4/CD8的比值,给药32周为明 In order to study the effect of the duration of administration of Buzhong Yiqi Decoction, the YAC-1 cells of mouse spleen NK cells administered at 32 weeks and 1 week were used as targets to investigate the cytotoxicity and the number of NK cells in the spleen and The ratio of CD4/CD8. As a result, after administration of Buzhong Yiqi Decoction for 32 weeks, the cytotoxicity of spleen NK cells was slightly increased, and it was significantly increased after 1 week of administration. Number of NK cells and CD4/CD8 ratio, 32 weeks after administration
