Lung microsomal membranes that contain the redox active components associated with the mixed-function oxidase system can be peroxidized in vitro. To investigate the characteristics of rat lung microsomal lipid peroxidation, we performed experiments using a variety of peroxidation initiators and microsomes obtained from normal and vitamin E-deficient rats. We found that lung microsomes obtained from normal rats are peroxidized much less than liver microsomes obtained from the same animals. Only initiation systems using very high concentrations of ferrous iron produced any significant peroxidation of normal rat lung microsomes. Lung microsomes obtained from vitamin E-deficient rats were found to be much more susceptible to peroxidation. Glutathione (GSH) was effective in inhibiting peroxidation when lung microsomes from normal rats were peroxidized. GSH was not effective in decreasing peroxidation when microsomes from vitamin E-deficient rats were peroxidized in the same system. We conclude that both GSH and vitamin E protect lung microsomal membranes from peroxidation. Glutathione protection appears to be related to the presence of a sulfhydryl group.
