|Title:||Influence of hormonal replacement on the ventral lobe of the prostate of rats (Rattus norvegicus albinus) submitted to chronic ethanol treatment|
|Abstract:||The harmful influence of the chronic alcohol ingestion on the male reproductive system leads to important alterations including hypogonadism and feminization, besides the morphological and functional disorganization of the different sexual glands. So, the aim of this study was to analyse the structural changes on the ventral lobe of the prostate of rats with hormonal replacement associated to chronic alcohol ingestion. A total of 30 rats (Rattus norvegicus albinus) was divided into three groups: control-received water; alcoholic-received ethanol diluted to 20% and hormone-treated alcoholic-received ethanol diluted to 20% associated with the administering of testosterome (5 mg/kg of weight) during the last 30 days of treatment. After 150 days of treatment, the animals were sacrificed, the prostate removed and submitted to transmission and scanning electron microscopies, histochemical analysis for acid phosphatase, testosterone level and stereologic analysis. In the alcoholic group the results demonstrated reduction of the total cellular volume and disorganization of the organelles involved in the secretory process. It was characterized a partial recovery of the cellular volume after treatment with testosterone. It was concluded that the ethanol impaired the cellular morphology and the hormonal replacement by itself did not bring about efficient remodeling of the organelles responsible for the secretory process.
