Effect of Annona muricata leaf ethanol extract on testosterone-induced benign prostatic hyperplasia in Wistar rats
Main Article Content
Abstract
Benign prostatic hyperplasia (BPH) has become the most common urological disease among aging men. This study investigated the inhibitory effect of Annona muricata leaf ethanol extract on a BPH animal model. Thirty male Wistar rats with weight range from 80-100g were divided into six groups: normal control (NC), testosterone-induced negative control (TC), Finasteride treatment control (FT), and the A. muricata low, medium, and high dose treatment groups: AML (100 mg/kg), AMM (200 mg/kg) and AMH (400 mg/kg) b.w respectively. BPH was induced by subcutaneous injection of testosterone propionate (5.0 mg/kg/b.w) for 28 consecutive days. Plant extract in vitro antioxidant activities were determined. After 14 days post-treatment, a 40% increase in prostate weight in the TC reflected a significant increase (p<0.05) in prostate index. The AMM and AMH groups showed significant reductions (p<0.05) in the prostate index, at approximately 50%. Prostate inhibition percentage of the FT at 45.26% and the AML, AMM and AMH at 43.4%, 42.1% and 44.4% were non-significant (p>0.05). In vitro antioxidant capacities were exhibited at 94.4% DPPH and 60% FRAP inhibition. This study therefore suggests that A. muricata is a potential candidate for the treatment of BPH.
