OBJECTIVE
Benign prostatic hyperplasia (BPH) is the most common prostate problem in older men. The present study aimed to investigate the inhibitory effect of Panax ginseng C.A. Meyer (P. ginseng) on a rat model of testosterone-induced BPH.
METHODS
The rats were divided into 3 groups (each group, n=10): control, testosterone-induced BPH (20 mg/kg, subcutaneous injection), and P. ginseng (200 mg/kg, orally) groups. After 4 weeks, all animals were sacrificed to examine the blood biochemical profiles, prostate volume, weight, histopathological changes, alpha-1D adrenergic receptor (Adra1d) mRNA expression, and epidermal growth factor receptor (EGFR) and B-cell CLL/lymphoma 2 (BCL2) protein expression.
RESULTS
The group treated with P. ginseng showed significantly lesser prostate size and weight than the testosterone-induced BPH group. In addition, P. ginseng decreased the mRNA expression of Adra1d as well as the expression of EGFR and BCL2 in prostate tissue.
CONCLUSIONS
These results suggest that P. ginseng may inhibit the alpha-1-adrenergic receptor to suppress the development of BPH.
