摘要: Abstract Oxidative damage to heme proteins in rat liver tissue slices was studied. Tissue were incubated KrebsRinger phosphate (KRP) buffer at 37°C with and without the presence of prooxidants. The absorbance spectra (500–640 nm) obtained from both spontaneous prooxidant-induced oxidation analyzed a protein analysis program (HPSAP) development this laboratory. dominant fresh nonperfused slice hemoglobin reduced cytochromes mitochondria. In an oxidized slice, major product hemichrome. Bromotrichloromethane, t -butyl hydroperoxide, ferrous ion accelerated oxidative reactions, amount products dependent on incubation time as well type concentration
