[HISTOLOGYCAL AND HISTOCHEMICAL CHARACTERISTICS OF AREOLAE IN THE PIG PLACENTA].
Rounded white lustreless dome-shaped wheels are detected by visually from allantochorion side in the in fetal areas epiteliochorial pig's placenta on day 30 of pregnancy. These structures are located over the opening of the uterine glands. Areolaes consist from maternal and foetal parts. Areola include glandular epithelium, chorial and endometrial stroma at the mouth of the uterine glands, areolar cavity-enhanced formed by endometrial and chorial invaginations. Chorion gives in cavity radial folds lining differences high epithelium. Glycogen, neutral and acid sulfated glycoproteins, proteoglycans, glycosaminoglycans, hyaluronates, total and cationic protein, RNA, arginine, gistidine, lysin were founded in structural components of areoles during gestation period. Numerous areolas serve as specialized sites for absorption the secrets of uterine glands; they are form a powerful functional system of histotrophic nutrition.
