激光穴位针刺对淋巴结作用的超微结构研究

EFFECT OF HE-NE LASER ACUPUNCTURE ON LYMPH-NODES IN RAS

氦氖(He-Ne)激光穴位照射,具有镇痛、消炎、提高机体免疫机能、促进血中免疫球蛋白(IgG、IgA、IgM·)浓度升高,并增强细胞免疫机能。但He-Ne激光穴位针刺对机体免疫器官的作用,特别对于产生免疫机能的T。

The lymphocytes and antigen presenting cells in lymph node of rats stimulated by He-Ne laser acupumture were observed by using TEM and SEM to investigate the ultrastructural changes of them. There were numerous actived T-cells which showed deeply indented nucleus, abundant small void mitochondria and fres ribosomes in the paracortex area. The B-cells were gradually differentiated into large lymphocytes, immature and mature plasmatic cells which with a lot of rough endoplasmic reticulum. They were prominently increased in the pulp area. The macrophages had short processes with numerous folds and microvilli and tended to neighboring lymphocytes. The nucleus pores were increased. There were a lot of pinocytosomes, phagosomes, lysosomcs in various size of macrophages. The bundles (5-6nm in diameter) of microfilaments of the macrophages were extended from the cytoplasm to the processes. The interdigitating cells which contained the characterized single layer of rER, numerous polysomes, mitochondria and well-developed Golgi-complex were closed to macrophages and lymphocytes. In conclusion the activities of the cellular immunity and humoral immutVity were enhanced by laser.
