Histochemical properties of the human mast cells (MCs) adjoining epithelia of epidermal and enterocoelodermal types have been studied. Slices from organs and tissues obtained from 40 corpses of persons died as a result of a sudden trauma were used as controls. Pathological material was presented by 48 diseases. Analysing peculiar histochemical properties of the MCs, situated near the epithelia, it was possible to reveal their two varieties. The MCs of the first variety give positive reaction to heparin only, while those of the second variety give positive reaction to heparin, protein, neutral and/or sialocontaining carbohydrate component. The both varieties of the MCs were found under normal and pathological conditions situating in the approximate vicinity to the epidermal epithelia. Near the enterocoelodermal epithelia (exept Müller's epithelium) both under normal and pathological conditions only the first variety of the MCs were revealed. Under Müller's epithelium, both under normal and pathological conditions, in some cases, only the first MCs variety was revealed, while in others - both varieties. A suggestion was made that peculiar histochemical properties of the MCs adjoining the epithelia and their derivatives express certain intertissue integration.
