Lipid peroxidation in developing rat brain during undernutrition.
The effect of undernutrition has been studied in relation to lipid peroxidation, both in vitro and in vivo, in the brain of developing rats. Lipid peroxidation in brain homogenates as well as in the mitochondrial fraction of brain was significantly higher in undernourished groups than in controls. This difference was maximal at the 12th postnatal day. Following rehabilitation for two weeks, this increased lipid peroxidation in brains of undernourished rats could no longer be observed. Determination of malonaldehyde levels in vivo did not show an appreciable difference between control and undernourished animals.
