FUNCTIONAL STATE OF VESSEL ENDOTHELIAL CELLS IN HYPERTROPHIC GINGIVITIS IN ADOLESCENTS
*Kamilov K. P. and Saidova N. A.
Endothelium - the inner lining of blood vessels - takes an active part in the regulation of vascular tone, producing various biologically active substances (BAS). Biologically active substances that act on the endothelium are produced by platelets, leukocytes, mast cells or are activated in the blood plasma, some of the substances are synthesized in the endothelium itself and act on the endotheliocytes either after they are brought into the bloodstream or paracrine.[5,11,12] The effect on the endotheliocytes of biologically active substances is associated with the presence of specific receptors on endotheliocytes, the stimulation of which causes vasodilation or vasocostriction.
