- Abstract
Objectives: Lysophosphatidylcholine (LPC) in low-density lipoprotein (LDL) comes into notice as an important atherogenic substance. Methods: Since the effect of probucol, an antioxidative lipid-lowering drug, on LPC molecular species has not been elucidated, two LPC molecular species, stearoyl LPC (SLPC) and palmitoyl LPC (PLPC), were measured in LDL using high-pressure liquid chromatography. LDL was obtained from 11 hyperlipidemic patients, including 9 diabetic patients, in comparison with 11 age- and gender-matched controls. Results and conclusion: Hyperlipidemic patients showed nearly twofold higher levels of SLPC and PLPC per gram of LDL protein than those of controls. All hyperlipidemic patients were treated with oral administration of 500 mg/day of probucol for 3 months. Both LPCs in LDL were significantly reduced to control levels and were increased again up to the pretreatment levels 4 weeks after cessation of the treatment. Therefore, probucol has a potent effect in reducing LPC and may contribute to decreasing the atherogenicity of LDL.
