The effects of Oleoreupien on prostate and seminal vesicle tissues in streptozotocin induced diabetic rats

Abstract

Diabetes impairs the normal reproductive system function by disrupting spermatogenesis and decreasing sperm count, serum testosterone level and seminal fluid volume. This study aimed to investigate the effects of oleoreupien on tissue changes of prostate and seminal vesicles in diabetic rats. Thirty male Wistar rats were randomly divided into 3 groups (n=10) including control, diabetic and treatment groups. Rats in the treatment group received Oleoreupien (500mg/kg) for 28 days by oral gavage after induction of diabetes by streptozotocin. At the end of the experimental period, samples of prostate and seminal vesicle were obtained and then slides were prepared and stained by H&E method for histological study. Morphological findings indicated increased secretion of prostate and seminal vesicles, significant increase in diameter of secretory units and significant decrease of interstitial connective tissue in the treatment group compared with the diabetic group. Histomorphometric results also indicated that epithelium height of the prostate and seminal vesicles and diameter of the tubules of the prostate significantly increased in the treatment group compared with the diabetic group (p ˂0.05). The study also revealed that gland weight to body weight in the treatment group increased significantly compared with that of the diabetic group (p ˂0.05). According to current findings, oral administration of Oleoreupien prevented diabetic induced tissue changes in prostate and seminal vesicle in rats.
