PG - 518-23 AB - The levels of lipid hydroperoxides and antioxidants in plasma samples from Nagase analbuminemic rats (NAR) and control Sprague-Dawley rats (SDR) were measured in comparison with those from normal human subjects. Cholesteryl ester hydroperoxide (CE-OOH) was detected, but phosphatidylcholine hydroperoxide was not. The levels of CE-OOH and the ratios of CE-OOH/CE were found to increase significantly in the order of human < SDR < NAR, suggesting that oxidative stress increases in the same order. NAR have a significantly lower level of ascorbate and lower ratio of ubiquinol/ubiquinone concentrations than SDR. This also suggests that NAR are subject to more oxidative stress than SDR, since ascorbate and ubiquinol are the most effective plasma antioxidants against oxygen radicals.
