Glutathione depletion and anaesthesia in mice alter heme and drug metabolising enzymes
The effects of enflurane and isoflurane on heme metabolism, its regulation, and on some parameters involved in the hepatic drug metabolising system in animals under GSH depletion were investigated. A single dose of the anaesthethics (1 ml kg-1, i.p.) was administered to control and GSH depleted mice...
