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.
Key words:
the uterus of pigs, myometrium, ratio of tissue components, histochemistry, glycogen, neutral
and acid sulfated glycoproteins, proteoglycans, glycosaminoglycans, hyaluronates, total and cationic protein,
RNA, arginine, gistidine, lysin
