Corticosterone and blood leukocyte variability during stress response

A comparative assessment of the effects of vibration and immobilization stressors on the secretory activity of the adrenal glands and the leukocyte pool of blood is given. It was found that under the action of acute stressors in the blood of laboratory animals, the concentration of corticosterone increases, reflecting both the degree of activation of the components of HPA and the duration of the release of the hormone from the adrenal glands into the blood. In the post-stress period, the concentration of lymphocytes in the blood of rats decreases and neutrophils increase. The severity of these changes is associated with the ability of the stressor to affect GH and determine the level of corticosterone in the blood.
