Does pretreatment with bilirubin protect islet against oxidative injury during isolation and purification?
We concluded that oxidative stress during islet isolation and purification can be mitigated by BR pretreatment. BR exerts antioxidant and cytoprotective properties by reducing lipid peroxidation (MDA) and enhancing islet viability and function. Pretreatment with BR may become a simple, clinical applicable means to improve human islet isolation and transplantation outcomes.
CuZn-SOD plays a protective role in the pathogenesis of selective hippocampal injury after brief ischemia, whether the insult is relatively mild or intense. Furthermore, CuZn-SOD may reduce both necrotic and DNA fragmented neuronal death after global ischemia.
