The metabolism of one-carbon compounds (C1 compounds) in higher plants mainly includes methanol metabolism,formaldehyde metabolism and formic acid metabolism,which is an important part in C1 unit metabolisms.

Effects of Different Profenofos Levels on the Activity of SOD and MDA of Rapes;

Study of NOS, MDA and immediate-early gene in rats' brain induced by methyl mercury;

Effects of Chlorpyrifos and Podophyllotoxin on Anti- oxidative Enzymes and the MDA of Vegetable(Brassica rapa L.);

ObjectiveTo explore the changes of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) in the brain of mice after irradiated by electromagnetic radiation (EMR) and therapeutic effect of curcumin.

The balance function, brain index, and the content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in the mouse cerebral cortex were tested after training.

Serum levels of malondialdehyde (MDA), superoxidase (SOD) and glutathione peroxidase (GSH-PX) were measured by chemocolorimetry in these subjects.

The biomass photosynthesis activity of Ruppia maritima and Potamogeton pectinatus and the proline,malondialdehyde(MDA),catalase(CAT),and chlorophyll contents in their leaf-tissues in response to salinity were studied by investigating the plants cultured with reclaimed wastewater of different salinities.

The effect of cadmium on the activities of superoxide dismutase(SOD),catalase (CAT),glutathione peroxidase(GPx) and the content of malondialdehyde(MDA) were observed in gonad of sea urchin Strongylocentrotus intermedius.

After 3d exposure,the superoxide dismutase(SOD)activities and malondialdehyde(MDA)contents in kidney and brain tissue were measured as indicators of oxidative da.
