We studied stress-induced organ and hormonal responses in behaviorally active and passive rats against the background of immunization with glutamate–BSA conjugate. The relative weight of the adrenal glands after immobilization was lower in rats immunized with the conjugate in comparison with non-immunized animals. The weight of the adrenal glands in behaviorally active rats decreased in parallel with the decrease in blood corticosterone. In behaviorally active and passive rats immunized with the conjugate, ulcer formation in the stomach was slightly intensified after immobilization. It was hypothesized that immunization with glutamate–BSA conjugate suppresses activity of the hypothalamic–pituitary–adrenal feedback mechanism underlying the production of glucocorticoid hormones, which is manifested in slightly increased ulceration due to attenuation of the gastroprotective action of corticosterone under stress.
