[Histochemical studies of the secretory capability of myometrial cells during pregnancy]

Investigations of many authors carried out on animals have shown the ability of myometrium cells to synthesize and secrete proteins and glycoproteid products in the period of pregnancy. The author's own studies have been carried out on human and animal material. In the muscles slices of gravid uterus as markers of appropriate cytoplasmatic structures were found out: S-nucleotidase, TPP-ase, succinat dehydrogenase, acid phopshatase and additionally glycogen. On the basis of the results obtained it may be concluded that in myometrium cells of gravid uterus morphological features of Golgi Apparatus (bacilliform, crescent, vesicular and granular structures) and mitochondria as well as the amount of glycogen manifest metabolic activity of these cells. Considering heterogenity of morphological forms of Golgi Apparatus and frequent charateristic polar localization round the nucleus it may be supposed that the cells charakterized by these features may possess the ability of secreting synthesized proteins or other products.
