[Retinyl palmitate and oxidative stress reduction in rats].
The effect of retinyl palmitate dose on oxidative stress reduction induced by physical activity was the aim of study. The experiment was carried out on Wistar strain males rats, which were trained by running on trademill with speed 20 m/min. during 10 days. The rats were administered with 7, 5, 15 or 60 microg of retinyl palmitate daily to each one. The level of retinol, lipid peroxides, antioxidant potential in serum and retinyl esters in liver were measured. It was shown that retinyl palmitate reduced oxidative stress, independently to its daily dose.
