Renal cadmium deposition and injury as a result of accumulation of cadmium-metallothionein (CdMT) by the proximal convoluted tubules--A light microscopic autoradiography study with 109CdMT.

Chronic, but not acute, exposure to inorganic Cd produces renal damage. However, a single injection of cadmium bound to metallothionein (CdMT) produces renal injury. It is hypothesized that an interorgan redistribution of Cd as CdMT is responsible for the chronic nephrotoxic effect of Cd.

Carbon tetrachloride-induced hepatotoxicity: studies in developing rats and protection by zinc.

This investigation was designed to evaluate carbon tetrachlorid (CCl4)-induced hepatotoxicity in developing rats and in adult rats pretreated with zinc. Hepatotoxicity of CCl4 in rats as young as 4 days of age was similar to that in adults. However, CCl4 metabolism, measured by in vitro binding of 14CCl4 to hepatic microsomal protein and lipid, was significantly lower in 4- and 14-day old rats than in adults.
