Effect of PFE on the prostatic hyperplasia in TP-induced rats. Prostatic tissues were stained with a H&E solution for histological examination (magnification, 200×). Representative photomicrographs of prostate sections are shown. NC (normal control group), corn oil injection (s.c.) + PBS administration (p.o.); BPH (control group), TP (3 mg/kg)/corn oil injection (s.c.) + PBS administration (p.o.); Fin (positive control group), TP (3 mg/kg)/corn oil injection (s.c.) + finasteride administration (10 mg/kg, p.o.); PFE (PFE-treated group), TP (3 mg/kg)/corn oil injection (s.c.) + PFE administration (200 mg/kg, p.o.). BPH, benign prostatic hyperplasia; Fin, finasteride; H&E, hematoxylin and eosin; PBS, phosphate-buffered saline; PFE, Ponciri fructus extract; p.o., peroral; s.c., subcutaneously; TP, testosterone propionate
