Abstract：
:We studied the circadian oscillation of lipid peroxides (TBARS) in the pineal gland of rats adapted to light:dark 12:12 h regimen. The concentration of TBARS was determined at 3-h intervals during 24 hours. TBARS of pineal gland oscillated rhythmically during the 24 h period. The maximal concentration of lipoperoxidative products was found at 20.00 h and 02.00 h and the lowest values at 08.00 h and 23.00 h. The determination of antioxidant capacity is needed for explaining the mechanism of TBARS oscillations in the pineal gland.
