Use of anabolic steroid altered the liver morphology of rats / El uso de esteroides anabólicos altera la morfología del hígado de ratas

The aim of this research was to investigate the effect of testosterone propionate administration in the liver of rats. The rats were divided in the following groups: Initial control (SC), Aged control (SE) and Anabolic group (SA). Testosterone propionate was administered three times per week during 16 weeks. Using morphoquantitative techniques, we quantified the volume densities of lobular and non-lobular parenchyma, area and number of nuclei of hepatocytes. The data were analyzed statistically using mean and standard deviation, ANOVA one-way and level of significance about p0.05. Our results showed an increase in capillaries, perisinusoidal spaces and biliary ducts in SE group compared to SC. SA group showed a decrease in hepatic cells, non-lobular volume density and hepatocytes nuclei area, but also an increase in capillaries, perisinusoidal spaces, biliary ducts, number of hepatocytes and non-hepatocyte nuclei compared to SC. We conclude that a direct toxicity may have occurred, with consequent loss of the cells.

El objetivo fue investigar el efecto de la administración de propionato de testosterona en el hígado de ratas. Las ratas se dividieron en los siguientes grupos: control inicial (CI), control de Edad (CE) y grupo anabólico (GA). El propionato de testosterona se administró tres veces por semana durante 16 semanas. Utilizando técnicas morfocuantitativas, determinamos las densidades de volumen del parénquima lobular y no lobular, área y número de núcleos de los hepatocitos. Los datos fueron analizados estadísticamente con la media y desviación estándar, la prueba de ANOVA de una vía y un nivel de significación p0,05. Nuestros resultados mostraron un aumento en los capilares, espacios perisinusoidales y conductos biliares en el grupo CE en comparación con CI. El GA mostró una disminución en las células hepáticas, la densidad de volumen no lobular y el área de los núcleos de hepatocitos, como también un aumento en los capilares, espacios perisinusoidales, conductos biliares, número de hepatocitos y núcleos no hepatocíticos en comparación AL CI. Concluimos que una toxicidad directa puede haber ocurrido, con la consiguiente pérdida de las células.

Luteinizing hormone reduction by the male potency herb, Butea superba Roxb.

To determine if Butea superba Roxb., a traditional Thai male potency herb, has androgenic activity in 60-day-old male Wistar rats, we measured its effects on the pituitary-testicular axis and sex organs. Intact and orchidectomized adult male rats were subdivided into five groups (10 rats/group): distilled water, Butea superba (BS)-10, BS-50, BS-250, and testosterone propionate (TP). They received 0, 10, 50, and 250 mg·kg body weight-1·day-1 BS in distilled water by gavage and 6 mg·kg body weight-1·day-1 TP sc, respectively, during the 30-day treatment period. Blood was collected every 15 days and luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone were measured. Changes of weight and histological appearance of sex organs were determined at the end of the 30-day treatment and 15-day post-treatment periods. TP treatment reduced serum FSH and LH levels and significantly increased the weight of the seminal vesicles and epididymis, in accordance with histopathological changes, in both intact and orchidectomized rats. No changes in serum testosterone, LH, and FSH levels were observed in any of the intact rats treated with BS, but a significant increase in seminal vesicle weight was observed only in the BS-250 group. Although a significant reduction in serum LH was detected in the BS-50 and BS-250 groups of orchidectomized rats, no significant change in weight or histology of sex organs was observed. Thus, we conclude that B. superba needs endogenous testosterone to work synergistically to stimulate the accessory sex organ of intact animals and can potentially exhibit an LH reduction effect in orchidectomized animals.
