Non-metallothionein-bound cadmium in the pathogenesis of cadmium nephrotoxicity in the rat.

abstract：:Cadmium (Cd(2+)) is a widespread environmental pollutant, which is associated with a wide variety of cytotoxic and metabolic effects. Recent studies showed that intoxication with the heavy metal most importantly targets the integrity of the epithelial barrier. In our study, the lung epithelial cell line, NCI H441, was...
