Abstract

BACKGROUND: Recently biphasic agarose gel electrophoresis method using Chol/Trig ComboTM for simultaneous detection of cholesterol and triglyceride on lipoprotein fractions has been developed to facilitate the classification and interpretation of abnormal lipoprotein patterns of patients with hyperlipidemia. The author analysed serum lipid profiles using Chol/Trig ComboTM in the patients of OPD in Department of Internal Medicine.
METHODS
Measurement of serum cholesterol and triglyceride using enzymatic method was performed in the sera of 415 patients from April, 2006 to July, 2006. Simultaneously, we electrophoresed serum cholesterol and triglyceride using Chol/Trig ComboTM with analysis software (ED BANK, Helena Laboratories, Saitama, Japan).
RESULTS
According to ATP III guideline, we set up standard cholesterol as 200 mg/dL and triglyceride as 150 mg/dL, respectively, and the patients were classified into control, hypercholesterolemic, hypertriglyceridemic and hypercholesterolemic/hypertriglyceridemic groups, respectively. Hypercholesterolemic group had higher HDL and LDL, hypertriglyceridemic group had higher HDL, VLDL and the rates of positive modified LDL, hypercholesterolemic/hypertriglyceridemic group have higher VLDL and the rates of positive modified LDL than the control. Otherwise, the rates of positive modified LDL were 19.8% in the control, 23.6% in the hypercholesterolemic group, 50.9% in hypertriglyceridemic group, and 39.3% in hypercholesterolemic/hypertriglyceridemic group.
CONCLUSIONS
The frequency of the rates of positive modified LDL and VLDL was higher in the hypertriglyceridemic group than those in the control.
