[Histochemical changes of the glycosaminoglycans in the uterine cervix of pregnant rats after local injection of hyaluronidase].

Purpose: to study the histochemical changes related to the uterine cervix glycosaminoglycan of the albino female rat, after local administration of hyaluronidases at the end of pregnancy.

Methods: ten female rats with positive pregnancy tests were randomly distributed in two numerically equal groups. The control group (Cg) was built up with rats that received a single dose of 1 mL of distilled water in the uterine cervix, under anesthesia, at the 18th pregnancy day.
