Effects of PV extract on the epithelium thickness of the prostate gland in a rat BPH model. (A) Representative images of hematoxylin and eosin (H&E)-stained prostate tissues (magnification, ×400). (B) The epithelial thickness of the prostate gland. NC, PBS- and corn oil-dispensed rats; BPH, PBS- and testosterone-dispensed rats; BPH + FIN, testosterone- and finasteride-dispensed rats; BPH + PV60, testosterone- and PV 60 mg/kg-dispensed rats; BPH + PV80, testosterone- and PV 80 mg/kg-dispensed rats. Representation of results as average ± SD. Comparison ## p < 0.01 with the NC group; comparison ** p < 0.01 with the BPH group.
