The intensity of lipid peroxidation was estimated by the content of its molecular products − diene conjugates (DC), and TBA-reagents and schiff bases in liver homogenate of rats (N = 30) which were ad-ministered small subtoxic doses of sodium fluoride. It has been found that oral administration of sodium fluoride in rats at doses of 1/10 and 1/100 LD50 promotes diene conjugates content in all periods of observation. In rat liver, starting from the 20th day, the gradual increase of TBA-reagents and schiff bases was clearly defined. Enhanced CL intensity estimates by 37 and 134% was detected in the case of sodium fluoride action at a dose 1/10 LD50, respectively. ER -
