Zinc, cadmium and selenium concentrations in separated epithelium and stroma from prostatic tissues of different histology.

The concentration of Zn, Cd and Se in unseparated tissues and epithelial and stromal fractions of normal prostate gland, BPH and prostatic carcinomas of different histological grading were determined by flameless AAS. There were distinct differences in the content of Zn, Cd and Se in the epithelial and stromal fractions depending on histology. In all cases the concentration of these elements in the epithelial fractions was higher than in stromal fractions. These differences are discussed.
