Biochemical and Histopathological evaluation of prostatic tissue under effect of Pterostilbene in benign prostatic hyperplasia rat model

Abstract

Background: Benign prostatic hyperplasia [BPH] is the urologic condition that affects elderly men the most frequently Benign prostatic hyperplasia. Benign prostatic hyperplasia must be distinguished from
 lower urinary tract symptoms and benign prostatic enlargement. which refers to an enlarged prostate, benign prostatic hyperplasia is a purely histological term the development, maintenance, and secretory activity of the prostate and other sex-accessory tissues are stimulated by the presence of certain hormones and growth factors. the pathophysiology of Benign prostatic hyperplasia is significantly influenced by the activity of the enzyme 5α-reductase. It's important to remember that 5-αreductase is responsible for creating Dihydrotestosterone a stronger androgen. Pterostilbene Mostly found in blueberries and grapes and pterostilbene substance with a number of biological properties including anticancer properties. pterostilbene is a lipid-soluble molecule that exists in both cis and trans forms with the latter being more prevalent. The conventional medication for Benign prostatic hyperplasia utilized in this trial was finasteride which inhibits the 5α-reductase enzyme and lowers the amount of Dihydrotestosterone.
 Methods: Forty-eight male rats were divided into six groups; the control group consisted of eight rats who received subcutaneous injections of oil vehicle for a period of 42 days. The induction group consisted of eight rats who received subcutaneous injections of testosterone propionate for a period of fourteen days. The finasteride group consisted of eight rats who received finasteride 0.44 mg/kg by oral gavage for a period of twenty-eight days following the induction of Benign prostatic hyperplasia and Pterostilbene 200 group included 8 rats were given pterostilbene 200mg/kg by oral gavage for 28 days after 14 days of Benign prostatic hyperplasia induction. pterostilbene 100 group included 8 rats were given a pterostilbene 100mg/kg per day kg by oral gavage for 28 days after 14 days of induction Benign prostatic hyperplasia dose and the resveratrol group included 8 rats were given a resveratrol 100mg/kg per day kg by oral gavage for 28 days after 14 days of induction Benign prostatic hyperplasia After twenty-eight days.
 Results: Histological section of prostate Pterostilbene 200 were similar those in control negative revealed numerous variable sizes alveoli that filled with homogenous eosinophilic secretion, had normal epithelial and stromal tissue.
 Conclusion: Pterostilbene have a potent anti-proliferative effect by decrease the hyperplastic nodules for prostate and return epithelial cell to normal and have a very good scavenging activity for free radical [very good as antioxidant] in compare with Vitamin c and resveratrol.
 Aim of study: evaluate the effect of Pterostilbene as Anti proliferative on Benign prostatic hyperplasia and assess the antioxidant activity for Pterostilbene by DPPH Assay.
