Paper Abstract

In order to study the effect of HeNe laser on macrophages phagocytosis, the are over liver and spleen of the mice was irradiated with NeHe laser at the dosage of 63.7J/cm2 for 3,5,7, and 10 days respectively, 5 min each day, then observing the phagocytosis of macrophages of the immune organs after trypan blue injecting live mice, and made quantitative analysis of macrophages phagocytosis by image analysis system. The results showed that the four indexes: number of trypan blue granule (GN), area of granule (GA), ratio of granule area to cell area (GA/CA) and granule integral optical density (IOD) at irradiated groups were higher than that of control group (P<0.01). Comparison between different irradiated groups were higher than that of control group (P<0.01). The study indicated that HeNe laser with appropriate dosage can activate macrophages of the immune organs, and enhance their organic immunity.
