He-Ne激光对家兔淋巴结影响的光镜和电镜观察

以Ｈｅ－Ｎｅ激光局部照射家兔颈前部及穴位照射，取颈前淋巴结进行光镜和电镜观察，同时用单向免疫扩散法测血清ＩｇＧ含量。结果表明，局部照射和穴位照射均能使淋巴结内多种细胞的超微结构发生改变，细胞功能表现活跃。穴位照射组血中ＩｇＧ含量较对照组明显升高。说明Ｈｅ－Ｎｅ激光照射增强机体细胞免疫和体液免疫机能是有细胞学基础的。提示穴位照射能增强全身免疫机能，而局部照射只能增强被照部位的免疫机能

Effect of He Ne Laser on Lymph nodes of Rabbits

Effect of He Ne laser irradiation of the cervicales anteriores region and of acupoint irradiation on rabbits is studied. The nodi lymphatici cervicales anteriores were observed by optical microscopy and transmission electron microscopy. The serum IgG was measured with a simple immunodiffusion method. The results showed that the ultrastructures of many kinds of cells in the lymph nodes both region irradiated and acupoint irradiated were changed. The function of the cells appeared activized. The serum IgG of the acupoint irradiation groups was much more than the control group. It was suggested that He Ne laser enhancing of cellular and humoral immunities of the organism was on the basis of changes of the cell ultrastructures. In conclusion, the immunity of the entire organism was enhanced by the laser acupoint irradiation, but the region irradiation only improved the immuniactivities of the irradiated region.
