He—Ne激光对小鼠睾丸影响的组织学观察及定量研究

HISTOLOGICAL OBSERVATION AND QUANTITATIVE STUDY ON MOUSE'S TESTIS WITH LASER IRRADIATION

以三种不同剂量的He—Ne激光分别照射三组雄性小鼠的阴囊,取睾丸作组织学观察及定量组织学研究。实验所用激光剂量为临床常用最大剂量的10～75倍。实验结果表明:所用三种剂量的He—Ne激光均无抗生精作用,不影响生殖细胞的正常增殖及雄性激素的分泌。提示以He—Ne激光照射阴襄治疗有关疾病,不致引起生殖细胞损伤及性功能的改变。

Scrota of mice divided into three groups were respectively irradiated by He-Ne laser of three different powers, the testes were taken for histological observation and quantitative histological study. The laser powers for the experiment were 10-75 times as large as the largest one for clinical treatment. The result showed three powers of He-Ne laser for the experiment hadn't an antispermatogenesis effect and could not exert influence on the normal reproduction of the spermatogenic cells and on secretion of the androgenic hormones. It is suggested that treating some diseases by irradiating the scrotum with He-Ne laser doesn't cause the reproductive cell damage and sex function change of the patient.
