Ultrasonic radiation produced a dose-dependent linear increase in lipid peroxidation in the liposomes membrane as reflected in the measurement of conjugated dienes, lipid hydroperoxides and malondialdehydes. Ultrasound induced malondialdehyde production could not be inhibited by any significant degree by superoxide dismutase or histidine or dimethyl furan but was very significantly inhibited by butylated hydroxytoluene, cholesterol, sodium benzoate, dimethyl sulphoxide, sodium formate and EDTA. The scavenger studies indicated the functional role of hydroxyl radicals in the initiation of ultrasound induced lipid peroxidation.
