[The elimination of stress-related changes in the thymus with the action of laser radiation on the endocrine glands].

: Experiments were carried out on male rats to study the stress-limiting effect of impulse infrared laser radiation (0.89 micron). The thymus and thyroid gland were subjected to 2 W localized impulse laser radiation with an impulse length of 7 x 10(-8) sec. and 3.000 Hz frequency. The following data were estimated: thymus weight, thymocyte population, acridine orange binding by thymocyte nucleus, protein content in thymocytes, the level of peroxide oxidation of lipids in thymocytes. It was revealed that the effect of laser radiation depends on the sequence of its application to stress animals rather than on its localization: its stress-limiting features were more effective when applied to stress animals rather than as a prophylactic measure.
