Increased metallothionein content in rat liver induced by X irradiation and exposure to high oxygen tension.
X irradiation and exposure to high oxygen tension are known to induce lipid peroxidation. The effects of these stresses on hepatic content of metallothionein, which may be involved in the regulation of zinc and copper metabolism, have been studied. The amount of metallothionein in rat liver was increased 11-fold by a high dose of X irradiation (1000 R). Increased metallothionein content (about 15 times) was also observed in liver of rats exposed to high oxygen tension for 3 days.
