Sažetak
Aging is a multi-factorial process which involves deprivation in body's metabolism. Brain mitochondria are prone to oxidative damage owing to their high metabolic rate. The decline in antioxidant system during aging augments the neuronal damage to mitochondrial components like antioxidant system, Kreb's cycle enzymes and electron transport chain complexes. Since brain is an organ rich in fatty acids, lipid peroxidation products like hydroxynonenal are predominant. Those lipid peroxidation products conjugate with amino acids to form adducts which alter their structural and functional properties. Epigallo catechin gallate is a potent antioxidant which is rich in green tea extract. This study elucidated the antioxidant potential of epigallo catechin gallate to counteract the mitochondrial oxidative damage in brain. The study comprised of young (3– 4 months old ; 150 ± 20 g) and aged (above 24 months ; 420 ± 20 g) male albino rats of Wistar strain in Groups I and II. Groups III and IV comprised of young and aged rats supplemented with epigallo catechin gallate (2 mg/kg body weight) for 30 days. Antioxidants, Kreb's cycle enzymes and electron transport chain complexes were assayed in the mitochondrial fraction. Hydroxynonenal expression was carried out using immunohistochemical analysis. Epigallo catechin gallate supplementation decreased the expression of hydroxynonenal in aged brain, up-regulated the antioxidant system and augmented the activities of Kreb's cycle enzymes and electron transport chain complexes in aged brain mitochondria thus proving its antioxidant potential at the level of mitochondria.
