Mucosubstances in the cervix uteri of the Indian langur monkey, Presbytis entellus entellus (Dufrense).

Mucosubstances in the cervix uteri of the Indian langur monkey, Presbytis entellus entellus was studied during non-pregnancy, pregnancy and lactation. Cells of the cervical epithelium and glands elaborated neutral, sialo- and sulfomucins during non-pregnancy. The concentration of these mucins was low during early pregnancy but increased during late pregnancy. The concentration of mucins was higher during later part of pregnancy than during non-pregnant stage which decline during lactation. Significance of mucins in cervix uteri and probable hormonal control over their elaboration is discussed.
