【摘要】 本文采用两种不同功率N₂激光对大鼠穴位照射后,观察其免疫功能状态的变化。结果表明低能量激光照射与大能量激光照射之间有明显差别。主要显示剂量与反应间关系具有累积作用。同时指出对激光照射盾引起机体免疫学效应有较高的敏感性,在制定治疗剂量与安全剂量时可作为观察指标。更多还原

【Abstract】 In this paper, we report the changes in the immunity indices in rats produced by skin irradiation with two different output of nitrogen laser (0.2 and 3 mJ)respective]y. The changes in the immunity indices of the low intensity (0.2mJ) and high intensity(3mJ)groups were compared. Results showed that there were slig-ht changes only in the low intensity group, as compared with the control group, where in the high intensity group significant changes were found. The relationship between the dose of laser irradiation and biological reponse was briefly discussed.更多还原
