Abstract
Although recent studies have shown that various stress can induce metallothionein (MT) synthesis in animal tissues, the induction of MT synthesis by exposure to static magnetic fields (SMF) has not been reported. We measured MT levels in the liver, kidney and brain of mice exposed to SMF and also evaluated the effect of SMF exposure on the induction of hepatic MT by treatment with carbon tetrachloride (CCl4). The MT content in the liver was significantly increased by exposure to 4.7 T of SMF for 6, 24, or 48 h, whereas that in the kidney or brain was not changed compared to the control. The combination of CCl4 injection and SMF exposure induced elevation of the hepatic MT content exceeding that induced by either treatment alone. These results indicate that exposure to the strong SMF induces MT synthesis in the liver in mice and enhances the hepatic MT synthesis induced by CCl4 administration.
