[Connective tissue under emotional stress].

The data pointing to morphofunctional changes in connective tissues of rats after exposure to acute experimental stress are presented. These changes were shown to be dependent on resistance of animals to emotional stress. Animals predisposed to the emotional stress developed more pronounced changes in connective tissues evident as tissue hemorrhages and edema, accumulation of hyaluronic structures, and degranulation and devastation of mast cells. Water immersion stress in these rats resulted in a significant decrease in uronic acids in the skin, damages of endotheliocytes and disruption of plasmalemma and basal membrane of the wall of the aortic arch ascending segment.
