摘要
The features of oxidative damage to type II collagen from pig cartilage, induced by · OH, O2- and fulvic acid from epidemic district of KBD, were studied in vitro. The results from amino acid analysis of the damaged collagen are characterized by a decrease in hydroxyproline and proline contents, and an increase in glutamic acid content. The change arc dependent on·OH and FA concentration. It is postulated that the FA or other toxic xenobiotics induce the generation of free radicals, which play the role of the trigger in KBD development.
