[Histochemical characteristics of mast cells in hemangiomas].

Mast cells of hemangiomas localized in the skin and in the mucous membrane of the oral cavity, have a similar histochemical characteristics of protein and carbohydrate components. The histochemical characteristics of the carbohydrate component indicate either a high (as compared with the norm) degree of sulfating of heparin molecules, or quantitative accumulation of its molecules in the mast cells cytoplasm. Moreover, in mast cells there were revealed protein and a neutral carbohydrate component. An assumption is put forward that histochemical changes in mast cells in hemangiomas were of compensatory-adaptive character and were directed to prevent the thrombogenesis in hemangiomas.
