RESPONSE OF ADRENAL BIOGENIC AMINES IN FEMALE RATS TO WATER-IMMOBILIZATION STRESS
Adrenal glands of 30 female rats were examined using luminescent-histochemical methods. The animals were divided into two groups: control rats and rats, which were subjected to water-immobilization stress lasting one hour daily during the period of 10 days. Animals were removed from the experiment in 30, 60 and 90 days after the end of exposure. It was found that the effect of water-immobilization stress changed the level of biogenic amines in the adrenal glands, the organ weight, the ratio (ST+HST)/CA and the number of luminescent granular cells. All these changes are of undulating nature and depend on the period of the study. It is probable that the alert stage developed in rats in 30 days after the end of exposure. In 60 days the stage of exhaustion begins. On the 90th day the stage of recovery forms in rats.
