HISTOCHEMICAL ASPECTS OF THE STATE OF MUCOSAL SUBPOPULATION OF THE MAST CELLS OF THE JEJUNUM AFTER ANTIORTHOSTATIC DISPLAYING
Mast cells (MCs) regulate adaptational mechanisms of the organism systems when exposed to space flight factors, especially weightlessness. They also influence the state of the connective tissue integrative and buffering metabolic environments and the intensity of the transport of metabolites from the capillaries to the functional elements of the body. The digestive system MCs are highly sensitive to gravity. This paper presents research results regarding the status of the mucosal subpopulation of MCs of the Mongolian gerbils’ jejunum in a simulated weightlessness environment.
