Popis: The production of thiobarbituric acid reactive substances (TBARS) and the content of reduced glutathione (GSH) were determined in primary monolayer cultures of adult rat hepatocytes and in their co-cultures with rat epithelial cells, both exposed for 90 min to 2 mm tertiary butylhydroperoxide. Under these stress-induced conditions, TBARS production tended to be less increased in co-cultured cells than in conventionally cultured hepatocytes. A total depletion of GSH content was measured in conventional cultures from the third culture day, whereas in co-cultures a decrease in GSH content was observed until the third day of culture, followed by a low but constant GSH level that was maintained until the end of the culture period. Oxidative stress appears to be less pronounced in co-cultures than in conventional cultures; the former cope better with externally induced oxidative stress than do the latter.
