[Localization of histamine in uterine structures].
By means of luminescent-histochemical method of Cross, Even, Rost histamine is revealed in all uterine structures. Visual and fluorometric data demonstrate uneven distribution of histamine in the organ's structures. A high content of histamine is specific for macrophages and mast cells, less high--in tegmental epithelium and endometrial glands. A low level of histamine have endometrial stroma, smooth myocytes, cells of the serous membrane and vessels. Basing on the literature data, concerning various sensitivity of the uterine tissues to estrogens and regarding effect of the estrogens upon histamine metabolism in the uterine and regarding interconnection of the histamine receptors in the uterus and the estrogens, a suggestion is made that various contents of histamine in the uterine structures depend on various amount of the histamine receptors in them and on different abilities of the uterine tissues to inactivate histamine. The ability of macrophages to accept free forms of bioamines, as it is described in the literature, evidently can be spread to the uterine macrophages, where a high content of histamine is revealed.
