Selenium concentration in the prostate

Samples of healthy tissue were taken from each of six prostatectomy specimens (55-72 yr), digested with acids, and analyzed for selenium by atomic fluorescence spectroscopy. The concentrations for five specimens were 1.32 +/- 0.09 microg Se/g dry wt (range 1.24-1.42) and 0.213 +/- 0.012 microg Se/g wet wt (range 0.200-0.229). The other specimen, from a 58-yr-old man who was the only one within this study to take a 200-microg Se/d dietary supplement, contained 2.72 microg Se/g dry wt and 0.421 microg Se/g wet wt.
