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...

A single dose of the anaesthethics (1 ml kg-1, i.p.) was administered to control and GSH depleted mice, animals were sacrificed 20 min after. As a consequence of GSH depletion, a significant inhibition in δ-Aminolevulinic acid synthetase activity, the first enzyme of heme bioxynthesis, and a striking induction in Heme oxygenase activity, the main enzyme of heme metabolism, were observed. Cytochrome P-450 levels and the activities of P-4502E1 and glutathione S-transferase were increased. These changes in heme metabolism and drug metabolising enzyme system were not altered further by the administration of enflurane or isoflurane. These findings would indicate that the status of oxidative stress produced by GSH depletion could not be affected by these anaesthetics and/or that disturbances in heme metabolism were already too important to undergo further variations. © 2005 Elsevier B.V.
