The incorporation of selenium and ytterbium into the eyes of mice.

The incorporation of Se and Yb into the eyes of mice has been studied. Selenodiglutathione, (GS)2Se, or ytterbium chloride, YbCl3, were injected intraperitoneally into mice: either alone, combined, or after various time intervals. Instrumental neutron activation analysis was applied as the analytical method for the determination of the levels of Se and Yb. The concentrations of both investigated elements were highest in the retinal tissue of the eye. YbCl3 influenced the distribution of Se in the eye.
