Abstract:

Benign prostatic hyperplasia (BPH) is an important key health concern for aging men. Polyphenolic compounds have been found to possess important roles in the inhibition of numerous ailments that involve reactive oxygen species and inflammation. Diosmin is a citrus flavone that possesses antioxidant, anti-inflammatory, antiproliferative, and anticancer activities, so based on these properties of diosmin, we decided to evaluate its effect on testosterone propionate (TP)-induced BPH. A total of 30 Wistar rats were randomly assigned to five groups having six animals in each. This study was of 28 days in which TP (5 mg kg) was administered to induce BPH in the last 10 days of the study. It was found that diosmin at the doses of 20 and 40 mg kgsignificantly reduced malondialdehyde and xanthine oxidase formation in a dose-dependent manner; however, it replenished catalase, glutathione (GSH), and GSH-dependent enzymes, that is, glutathione peroxidase, glutathione reductase, and glutathione--transferase significantly against TP-induced BPH. Further, immunohistochemical study showed that diosmin alleviated inflammatory markers (nuclear factor kappa-light-chain-enhancer of activated B cells, cyclooxygenase-2, and interleukin-6). It was also found that diosmin downregulated the expression of androgen receptor and decreased the prostate-specific antigen concentration dose-dependently, significantly against TP-induced BPH. Diosmin also restored histoarchitecture of the prostate in a dose-dependent manner. Findings from the present study revealed the protective role of diosmin against TP-induced BPH in Wistar rats.
