Concentrations of metals in the Harderian glands of male and female hamsters

Abstract 1. 1. Harderian glands of male hamsters possess lower concentrations of Na, Mn and Ca and higher concentrations of Fe and Mo than those of females. 2. 2. Pinealectomy has little influence on metallic concentrations in these glands. 3. 3. Gonadectomy increases concentrations of Na, Cu and Mn in the male and Fe in the female and decreases Mo in the male. 4. 4. Blinding decreases Zn in both sexes and Mn in the female and increases Ca in the male and Cu and Mo in the female. 5. 5. The data strongly suggest that Mo is associated with cell type II in the male and Mn with cell type I in both males and females.
