Abstract

BackgroundAtypical prostatic hyperplasia APH is a pseudoneoplastic lesion that can mimic prostate adenocarcinoma because of its cytologic and architectural features. Suspension of date palm pollen DPP is an herbal mixture that is widely used in folk medicine for male infertility. The aim of the present study was to evaluate the effect of DPP suspension and extract on APH-induced rats.

MethodsAPH was induced in adult castrated Wistar rats by both s.c. injection of testosterone 0.5 mg-rat-day and smearing citral on shaved skin once every 3 days for 30 days. Saw palmetto 100mg-kg, DPP suspension 250, 500 and 1000 mg-kg, and lyophilized DPP extract 150,300 and 600 mg-kg were given orally daily for 30 days. All medications were started 7 days after castration and along with testosterone and citral.

ResultsThe histopathological feature in APH-induced prostate rats showed evidence of hyperplasia and inflammation. Immunohistochemical examination revealed that the expressions of IL-6, IL-8, TNF-α, IGF-1 and clusterin were increased, while the expression of TGF-β1 was decreased that correlates with presence of inflammation. Moreover, histopathological examination revealed increased cellular proliferation and reduced apoptosis in ventral prostate. Both saw palmetto and DPP treatment has ameliorated these histopathological and immunohistochemical changes in APH-induced rats. These improvements were not associated with reduction in the prostatic weight that may be attributed to the persistence of edema.

ConclusionDPP may have a potential protective effect in APH-induced Wistar rats through modulation of cytokine expression and-or upregulation of their autocrine-paracrine receptors.
