Effects of PV extract on prostate cell proliferation in a rat BPH model. (A) Respective images showing immunohistochemical analysis of targeting proliferative cell nuclear antigen (PCNA, magnification, ×400). (B) Quantitative analysis of PCNA-positive cells. (C) Expression of cyclin D1. 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.
