Bromine and selenium in human aorta

The bromine and selenium concentrations of healthy and atheromatous human aorta and of other organs are reported. No relation between age and concentration in the aorta is found. The selenium levels of the aorta are similar to those of other internal organs; the content of the three layers show no significant differences. The bromine concentrations of the media are higher than those of the other layers, which are similar to those of the internal organs. A possibly greater concentration of bromine in atheromatous medial tissue is indicated.
