摘　　要：目的探讨维生素C(Vitamin C,VC)对巨噬细胞增殖、迁移和吞噬能力的影响。方法体外无菌分离和培养大鼠腹腔巨噬细胞,培养液中加入VC处理24 h,然后利用Brd U和WST技术检测巨噬细胞的增殖能力,荧光微球法检测吞噬功能,划痕实验和Transwell小室检测迁移能力。结果 VC组中巨噬细胞Brd U阳性率和WST吸光度均显著高于对照组(P<0.05),提示VC能够促进巨噬细胞的增殖;在培养液中加入荧光微球后巨噬细胞能吞噬微球,且VC组巨噬细胞吞噬的微球数量显著多于对照组(P<0.05);另外巨噬细胞穿过Transwell小室及划痕后迁移的速度在VC处理后也明显加快(P<0.05)。结论VC能显著提高巨噬细胞的增殖、迁移与吞噬能力。Objective To investigate the effects of Vitamin C （VC） on macrophage proliferation, migration and phagocytic activity. Methods Macrophages isolated from SD rats were cultured in a basic medium supplement with or without VC for 24 hours. Then the proliferation of macrophages was assessed by BrdU and WST assays, while the phagocytic activity was detected by the phagocytosis of lumispheres which were administrated into the culture medium for 3 hours, and the migration was measured by scratching test and Transwell assay. Results The percentage of BrdU positive cells was significantly increased in the VC treated group while the intensity of WST test was higher in VC group than that of control group （P〈0.05）. The number of lumispheres in each macrophage of VC group was much more than that of control group（P〈0.05）. Moreover, VC could accelerate the migrating rate of macrophages when the cells were tested by scratching test and Transwell assay （P〈0.05）. Conclusion VC could enhance the proliferation, migration and phagocytosis of macrophages.
