ABSTRACT
The present research had the purpose to analyze morphologically the sites of endometrial implants on the external area of the musculature of the anterior abdominal wall of female rats, treated with dexamethasone. For so, these 15 albino female rats were used (Rattus norvegicus albinus), of the lineage Wistar with 90 days of age, that were submitted to the induction of the endometriosis, and divided in the following groups Group I ­ induced female rats to endometriosis and evaluated after 21 days (control); Group II ­ induced female rats to endometriosis and after 21 days, treated with dexamethasone for 10 days; Group III - induced female rats to endometriosis, and after 21 days, treated with dexamethasone for 15 days. The dexamethasone was administered in the dosage of 0,8 mg/day/animal. Our results showed that the chronic inflammatory process in the endometriosis doesn't decrease after treatment with dexamethasone for 10 days, while the treatment with dexamethasone for 15 days reverted the chronic inflammatory process in the endometriosis, besides stimulating the proliferation of glands in endometrial implants.
RESUMEN
El objetivo de la investigación fue analizar morfológicamente los sitios de implantes endometriales sobre la región externa de la musculatura de la pared abdominal anterior de ratones, tratados con dexametasona. Para ello, fueron utilizados 15 ratones albinos (Rattus norvergicus albinus), del linaje Wistar, de 90 días de edad, los cuales fueron sometidos a inducción de la endometriosis y divididos en los siguientes grupos Grupo I ­ ratones inducidos a la endometriosis y evaluados tras 21 días (control); Grupo II ­ ratones inducidos a la endometriosis y tras 21 días, tratados con dexametasona durante 10 días; Grupo III ­ ratones inducidos a la endometriosis, y tras 21 días, tratados con dexametasona durante 15 días. La dexametasona fue administrada en dosis de 0,8mg /día/animal. Nuestros resultados muestran que el proceso inflamatorio crónico en la endometriosis no baja después del tratamiento con dexametasona durante 10 días, mientras que el tratamiento con dexametasona durante 15 días cambió del proceso inflamatorio crónico en la endometriosis y estimuló la proliferación de glándulas en los implantes endometriales.
