CHANGES IN COLLAGEN METABOLISM PARAMETERS DURING EMOTIONAL STRESS ^{[№ 2 ' 2010]}
The paper examines the influence of emotional stress on the functional activity of systems that provide adaptation and change in intensity of the processes of collagen metabolism in these conditions. Exam stress was selected as a model of emotional stress. At the exam the students showed activation of the sympathetic-adrenal and hypothalamic-pituitary-adrenal systems, reducing the intensity of the collagen synthesis. The level of collagen degradation in the exam stress in normosthetic and concordant students remained unchanged, while the diskordant students displayed increased collagen degradation activity.
