Research Abstract

F344 rat prostatitis model using lipopolysaccharide(LPS) was established. PhIP(2-amino-1-methyl-6-phenylimidazo[ 4, 5-b] pyridine)-induced abnormal proliferation of rat prostate epithelial cells was enhanced by LPS-induced inflammation. Moreover, clinicopathological studies using human prostate biopsy specimens suggest that infiltration of mast cells or macrophages positively correlated with occurrence or progression of prostate cancer.
