Altered lipid parameters in hepatic subcellular membrane fractions induced by fumonisin B1.

abstract：:An improved method was developed for measuring malondialdehyde (MDA) as its thiobarbituric acid (TBA) complex. Samples were initially incubated with 1% potassium iodide and 0.1% butylated hydroxytoluene at 50 degrees C for 20 min, and then with 0.4% TBA at 60 degrees C for 60 min. The MDA-TBA complex formed was extrac...
