采用两种不同功率的He—Ne激光分别照射小白鼠胸腺区、脾区及腹部,观察体液免疫、细胞免疫及腹腔巨噬细胞吞噬功能。结果表明激光照射组与对照组有显著差异(P<001),故证明激光有免疫调节剂的作用。为激光的临床治疗提供了可靠的理论依据。 Two different power He-Ne lasers were used to irradiate the thymus, spleen, and abdomen of mice, and humoral immunity, cellular immunity, and phagocytic function of peritoneal macrophages were observed. The results showed that there was a significant difference between the laser irradiation group and the control group (P < 001), so it was proved that the laser has the effect of an immunomodulator. It provides a reliable theoretical basis for the clinical treatment of laser.
