Antioxidant action of grape seed polyphenols and aerobic exercise in improving neuronal number in the hippocampus is associated with decrease in lipid peroxidation and hydrogen peroxide in adult and middle-aged rats.

Antioxidant action of grape seed polyphenols and aerobic exercise in improving neuronal number in the hippocampus is associated with decrease in lipid peroxidation and hydrogen peroxide in adult and middle-aged rats. Exp Gerontol. 2017 Nov 22;: Authors: Abhijit S, Tripathi SJ, Bhagya V, Shankaranarayana Rao BS, Subramanyam MV, Asha Devi S Abstract The present study explored the effects of swimming training and grape seed proanthocyanidin extract (GSPE) on neuronal survival in the hippocampus (HC) of middle-aged rats along with oxidative stress (OS) parameters. Further, the bioavailability of the GSPE, catechin, epicatechin and gallic acid were measured in the HC and plasma. Male Wistar rats were grouped into: sedentary control, SE-C; swimming trained, SW-T; SE-C, supplemented sedentary, SE-C(PA) and swimming trainees, SW-T(PA). The supplement was a daily dose of 400mg GSPE/kg body weight. Swimming training lasted for 2h/day and for 14weeks. Glutathione level was increased in response to single and combined interventions in the middle-aged rats. Adult trainees showed increased glutathione peroxidase activity unlike middle-aged wherein increase was seen in SE-C(PA) alone. Lowered catalase activity with age in the HC increased in response to the combined interventions although single interventions were also effective. HC from both ages showed decrease in lipid peroxidation and hydrogen peroxide levels in response to the interventions. G...
