Selective Accumulation of Cd 115 by Cortex of Rat Kidney. ∗

Abstract

Summary

Using radioisotopes another element, cadmium, has been found to selectively accumulate in one tissue, the kidney cortex of the rat, in concentrations sufficient to warrant its use as a research tool. The cortex of the young rat, which contains only one-third the number of nephron units found in the adult, is unable to concentrate Cd¹¹⁵ at the adult level. The studies reported indicate a possible physiological role of cadmium in renal function.
