Aim:Benign prostatic hyperplasia and prostate cancer is an internationally important health problem of the man,particularly in developed *** aim of this exploratory study was to evaluate whether significant difference in the levels of Zn and some other trace elements of prostatic fluid exist between the inflamed and malignantly transformed ***:prostatic fluid levels of Br,Fe,Rb,Sr,and Zn were prospectively evaluated in 52 patients with benign prostatic hyperplasia and 24 patients with prostate *** were performed using 109Cd radionuclide-induced energy dispersive X-ray fluorescent *** fluid samples were divided into two *** was used for cytological study to exclude prostatitis,while the other was intended for trace element ***:Mean values±standard error of means for concentration(mg/L)of trace element in the prostatic fluid of hyperplastic prostate were:Br 2.32±0.30,Fe 11.5±1.8,Rb 1.70±0.23,Sr 1.41±0.26,and Zn 488±*** contents of Rb and Zn were significantly lower(approximately 3.2 and 7.7 times,respectively)in fluid of cancerous prostate compared with those in fluid of hyperplastic ***:There are significant differences in trace element contents in the fluid of hyperplastic and malignantly transformed *** great decrease in levels of Rb and Zn in the fluid of cancerous prostate might demonstrate ;an involvement of these trace elements in etiology and pathogenesis of malignant prostate *** was supposed that the differences in Rb and Zn levels in prostatic fluid can be used as tumor markers.
