|Increasing evidence suggests that thymoquinone (TQ), the principal bioactive constituents of Nigella sativa oil, exhibits antiinflammatory, anti-oxidant and anticancer effects on in vitro and in vivo models. Benign prostatic hyperplasia (BPH) is the most common age-related disease in men. The present study was intended to address the possible protective effects of TQ on the histopathological changes related to the BPH induced by testosterone in rats. A total of 34 adult male Wistar rats were divided into four groups. A negative control group (n=10) received vehicle orally (corn oil, 2 ml/kg) and two groups were injected testosterone subcutaneously (3 mg/kg) to induce BPH. Animals receiving testosterone were randomized to untreated BPH group (n=6,) and BPH+TQ treated group (n=6, 50 mg/kg orally) for 14 days. Histological changes and the mRNA levels for transforming growth factor beta1 (TGF-β1), an inflammatory cytokine, and vascular endothelial growth factor-A (VEGF-A), a biomarker of angiogenesis, were assayed in the prostate tissue. There were significant increases in prostate weight, prostate body weight ratio, and the expression levels of TGF-β1 and VEGF-A in the untreated BPH group compared to the control group. Histological examination of the prostate in the BPH group showed morphological abnormalities such as a higher degree of proliferation in the glandular epithelial and stromal area with numerous intraluminal papillary folds. In TQ treated rats, however, a reduction in the prostate weight, prostate body weight ratio, epithelial hyperplasia and the expressions of TGF-β1 and VEGF-A were observed compared to the BPH rats. These results suggested that TQ inhibited the development of BPH and might be a useful herbal treatment for BPH.|
