Protection of myocardial mitochondria against oxidative damage by selenium-containing abzyme m4G3
Selenium-containing abzyme (m4G3) was prepared and its protection of myocardial mitochondria against oxidative damage was studied using the swelling of mitochondria, quantity of lipid peroxidation products, and change in cytochrome-c oxidase activity as a measure of mitochondrial damage. The results...

| description | Selenium-containing abzyme (m4G3) was prepared and its protection of myocardial mitochondria against oxidative damage was studied using the swelling of mitochondria, quantity of lipid peroxidation products, and change in cytochrome-c oxidase activity as a measure of mitochondrial damage. The results showed that m4G3 could inhibit mitochondrial damage caused by the hypoxanthine-xanthine oxidase system in vitro. Electronic spin resonance (ESR) studies demonstrated that m4G3 could decrease the amount of free radicals generated in the damage system. |
