[STEREOMETRICAL AND HISTOCHEMICAL ORGANIZATION OF THE PIGS MIOMETRIUM].

There are too functionally ambiguous layers in myometrium of pigs. One of them is inner circular and the other one is outer longitudinal layers of smooth muscle cells bundles. The length of myocytes in both layers of the myometrium was significantly increased deepening of gestation periods. Ratio of circular and longitudinal layers, connective tissue, vasculature of the myometrium is not the same in cranial, fetal and interfetal segments of horns. It changes depending on the physiological state. Glycogen, neutral glycoproteins, acidic sulfated glycoproteins and proteoglycans, hyaluronates, RNA, amino acids, lysine, histidine and arginine have been histochemically identified in the tissue components of the muscle tunic. Their dynamics and qualitative distribution have cellular and tissue specificity in different physiological periods.
