作者采用大功率He—Ne激光照射口腔溃疡病灶区,观察临床效果,检测激光照射对血中免疫球蛋白、补体、循环免疫复合物水平及淋巴细胞转化率的影响。结果表明,激光照射治疗复发性口腔溃疡,有良好的临床效果,治愈率82％,总有效率达100％;激光照射具有免疫增强效应,照射前后系列免疫指标比较(P<0.01),差异有高度显著性。 The authors used high-power He-Ne laser irradiation of oral ulcer lesions to observe the clinical effect of laser irradiation on serum immunoglobulin, complement, circulating immune complex levels and lymphocyte transformation rate. The results showed that the laser irradiation treatment of recurrent oral ulcer, a good clinical effect, the cure rate was 82%, the total effective rate of 100%; laser irradiation with immune enhancement effect, before and after irradiation series of immune indicators (P <0.01), the difference was Highly significant.
