Experiments were carried out on male rats to study molecular background of stress-limiting effect of impulse infrared laser radiation (0.89 mu). The motor cortex was subjected to 4.8 W local impulse laser radiation with an impulse length 10(-8) sec, 3000 Hz base frequency and 10 Hz modulating frequency during 10 minutes. The following data were estimated: DNA synthesis in the cells of the cortex, skeletal muscles and thymus recorded by 3H-thymidine inclusion in nuclear DNA, 11-OCS content in blood plasma. It was revealed that IR radiation stimulated DNA synthesis in all the examined tissues of intact animals and animals after proactive physical load (swimming). The preliminary laser radiation was an effective stress-limiting factor for the cortex and thymocytes of swimming rats, but did not prevent decreasing 3H-thymidine inclusion in muscles' nuclear DNA initiated by swimming.
在雄性大鼠身上进行了实验，以研究脉冲红外激光辐射（0.89微米）的应激限制作用的分子背景。对运动皮层进行4.8瓦的局部脉冲激光辐射，脉冲长度为10(-8)秒，基频为3000赫兹，调制频率为10赫兹，持续10分钟。评估了以下数据：通过3H-胸腺嘧啶核苷掺入核DNA记录的皮层、骨骼肌和胸腺细胞中的DNA合成，血浆中11-OCS的含量。结果显示，红外辐射刺激了完整动物以及进行主动体力负荷（游泳）后的动物的所有检测组织中的DNA合成。预先的激光辐射对游泳大鼠的皮层和胸腺细胞是一种有效的应激限制因素，但不能阻止游泳引发的肌肉核DNA中3H-胸腺嘧啶核苷掺入量的减少。
