title: Assay of free-radical toxicity and antioxidant effect on the Hep 3B cell line: a test survey using lindane.
abstract: The content of reduced glutathione and of glutathione disulfide as well as the activities of glutathione reductase, glutathione peroxidase, glutathione S-transferases, catalase and superoxide dismutases were determined in human hepatoma Hep 3B cells in relation to free-radical toxicity in order to appreciate the defense capacities of these cells compared to data on normal hepatocytes. When Hep 3B cells were exposed to lindane, a known inducer of free-radical production, superoxide dismutase activity appeared as the best-adapted cellular parameter for early detection of the resulting free-radical toxicity.
