The Effect of Dalargin on the Level of Corticosterone in Rats with Different Individual Typological Features of Behavior in the PTSD Model
Abstract
The effect of the synthetic analogue of leu-enkephalin (dalargin) on the level of corticosterone in the blood and the mass of the adrenal glands in rats with various typological features of behavior in the model of post-traumatic stress disorder (PTSD) was studied. Groups were formed: active low-anxiety (ALA) and high-anxiety (AHA), as well as passive low-anxiety (PLA) and high-anxiety (PHA) rats. Each of the four groups of rats was divided into three subgroups, where subgroup 1 is an intact control. Twenty days after the first stressful exposure, rats from subgroup 3 were injected intramuscularly with dalargin for seven days, and rats from subgroup 2 were injected with saline solution. It was found that the course of injections of dalargin into rats in the PTSD model had a positive effect on the studied indicators only in the group of active high-anxiety animals.
