氦氖激光对离体小鼠腹腔巨噬细胞功能的影响

The Effect of phagocytolysis of Mice Macrophagus Cells of Peritoneal Cavity Irradiated in Vitro with Helium Neon Laser

为探索低功率激光照射治疗的机理，本实验用氦氖激光（功率１０．２ｍＷ）照射离体小白鼠腹腔巨噬细胞观察其吞噬鸡红细胞的功能。当照射１５分钟时（光剂量１．１４Ｊ／ｃｍ２），巨噬细胞吞噬功能达最大值，以后开始下降，照射至４０分钟时（光剂量３．０４Ｊ／ｃｍ２），巨噬细胞吞噬功能下降至对照组以下，出现抑制现象。

In order to investigate the therapeutic mechanism with the low power heliumneon laser irradiation, the experiment was inspected a function of the phagocytolysis chick red blood cells, which was irradiated in vitro using output power 10.2 mW of the HeNe laser to the mice macrophagus cells in the peritoneal cavity. After the laser irradiated 15 min (dose 1.14 J/cm 2), the level of the phagocytolysis rose a maximum. The phagocytolysis action appeared repression as the laser irradiated 40 min (dose 3.04J/cm 2). The relation between the laser irradiated dose and the phagocytic function of the macrophage show a parabolic curve
