Histomorphological effects of the oil extract of Sphenocentrum jollyanum seed on benign prostatic hyperplasia induced by exogenous testosterone and estradiol in adult Wistar rats

Abstract

<span style="font-size: medium;">benefits due to its very potent anti-inflammatory and antioxidant properties. Despite its widespread use, it has not been validated for use in the treatment of benign prostatic hyperplasia (BPH). This study was conducted to examine histomorphological effects of SJ seed on BPH that usually causes bladder outlet obstruction.</span> <span style="font-size: medium;"><strong>Materials and Methods: </strong>There were a total of six groups of animals each comprising 5 adult male rats. Apart from group 1 (normal control), in the remaining five groups, BPH was induced. Group 2 (negative control) was sacrificed immediately after BPH induction; groups 3 and 4 received the extract at 300 and 600 mg/kg respectively by gavages for thirty days; group 5 received finasteride (0.1 mg/kg) for thirty days and group 6 received the extract (600 mg/kg) simultaneously with the steroid administration for thirty days. The animals' were weighed before the experiment and subsequently every three days until the end of the study.</span> <strong><span style="font-size: medium;">Results: </span></strong><span style="font-size: medium;">The extract caused marked decrease in prostate weight of rats with BPH with histo-morphology of the tissue showing degenerated stromal and epithelial cells with few epithelial involutions of glandular tissue. Prostate specific antigen (PSA) level as well as testosterone level significantly (p<0.05) decreased in the treated groups compared to negative control. BPH animals treated with extract</span><span style="font-size: medium;">/finasteride exhibited remarkable increases in anti-oxidant enzymes level with concurrent decreases in peroxidative activity.</span> <strong>Conclusion: </strong>SJ effectively ameliorated prostatic hyperplasia in BPH animals causing marked degenerative changes in prostate stromal and epithelial cells and also exhibited marked anti-oxidant effect.
