[Granular biogenic amine-containing cells of the rat endometrium as components of the system of mononuclear phagocytes].

[Article in Russian]


To 10 non-inbred white mature rats 24 h before sacrifice 7.0 ml of Indian ink colloid solution has been injected intraperitoneally. Histochemical reactions of Falk-Hillarp (catecholamines, serotonin) have been performed on nonfixed cryostat slices of the uterus, those of Cross, Even, Rost (histamine) against non-specific esterase and acid phosphatase. Before carrying out these reactions, the slices have been examined under luminescent microscope LUMAM-I3 by means of luminescent and usual illumination in order to reveal cells, possessing autoluminiscence and containing phagocyted Indian ink particles. Presence of autoluminescence, phagocyted material, catecholamines and serotonin, histamine, nonspecific esterase, acid phosphotase, prostaglandin E2 in the same granular cells of the rat endometrium have been stated. All cellular properties revealed are specific for macrophages. A conclusion is made that granular biogenic amine-containing cells of endometrium can be considered as belonging to the system of mononuclear phagocytes.
