HISTOLOGICAL EVALUATION OF ENDOMETRIOSIS IN RATS, DURING THE PHASES OF THE ESTROUS CYCLE

ABSTRACT

The present research was aimed to morphologically analyze the endometrial implant sites of on the external area of the musculature of the abdominal wall of female rats, during the estral cycle. Sixteen albino female rats were used (Rattusnorvegicusalbinus), of the lineage Wistar with 90 days of age, obtained from the lab. animal rearing facilities of the Department of Morphology and Animal Physiology of UFRPE, which were submitted to the induction of the endometriosis. The histologic analysis of the implants was accomplished by means of light microscopy, using Hematoxilin-Eosin (H-E) and Mallory’s Trichrome staine. The collected material was fixated in Boüin's liquid and processed for inclusion in paraplasts. The results showed that the proestrus, estrus and diestrus phases were more favorable for the development of the endometrial implants in female rats, when compared to the metaestrus phase.
