不同剂量的He-Ne激光对妊娠母鼠子代的生长及行为的影响

目的：He-Ne激光对妊娠母鼠进行照射后，观察对其子代的致变效应。方法：取雌雄小白鼠若干。当母鼠怀孕后开始进行激光照射，随机分成4组，照射时间为0,10，30,60min。当子鼠出生30d后，对其进行生长和行为的观察。结果：不同剂量的He-Ne激光照射妊娠母鼠，其子代的体重，学习记忆力、耐寒能力和缺氧环境适应能力有所不同。结论：He-Ne激光对生物体的致变效应是存在的，且与激光的剂量有关。

Effects of He-Ne laser of different dosage irradiation gravid Mouse:study young mice in the growth And behavior

Aim:Different dosage He-Ne laser irradiate gravid mice,observe the effects of causing change to young mice.Method:Take some male and female mice.After female mice become pregnant,they are irradiated by laser.Gravid mice are divided into 4 groups,and the time of irradiation are 0,10,30,60 min.When young mice grow 30d,they are observed in growth and behavior.Result:After gestation mice are irradiation by He-Ne laser of different dosage,its filial generation in avoirdupois,recall ability of study,ability of bear cold and the adaptability of circumstance in lacking oxygen are different.Conclusion:When He-Ne laser irradiate organism the effect of causing change is existent ,and the effect is relate to dosage of laser.
