Effect of laser radiation on thymus hormones production

Irradiation of the epithelial cells from human (cell line HTSC) by arsenid-gallium laser (0.89 nm, 1500 Hz) induces an enhancement of thymic hormone production. The concentration of α-1-thymosin was substantionally increased on the days 1 and 5 in culture after irradiation. The increase of thymulin level in cultural supernatants was less pronounced and displayed after irradiation during 3-4 minutes. Local laser irradiation of thymus region of rats (5 minutes, 10 times) induce the increase of serum concentration of α-1-thymosin and the decrease of serum level of thymulin 2 days after irradiation. 10 refs.; 2 figs
