Ozone exposure modifies prostaglandin biosynthesis in perfused rat lungs
Research Communications in Chemical Pathology and Pharmacology
|September 1, 1976
Abstract:
Exposure of perfused rat lungs to 3.0 ppm of ozone produced a rapid onset of edema and an increased resistance to inflation. Both the Km and Vmax of the enzymic conversion of arachidonic acid to prostaglandins were decreased by ozone exposure suggesting an uncompetitive inhibition of prostaglandin synthetase by O3. Reduced glutathione failed to prevent the inhibition of prostaglandin synthesis by O3.
