This study was carried out to compare serum lipid levels in 20 chronic alcoholics to those in 30 normal subjects. The mean systolic blood pressure in normals and chronic alcoholics were 113.0$pm$16.9mmHg and 125.5$pm$13.4mmHg, respectively. The differences between the two groups were significant(p〈0.01). The serum total cholesterol and triglyceride were 158.8$pm$32.9mg/이 and 104.6$pm$48.8mg/이 in normals and 204.9$pm$45.8mg/이 and 206.5$pm$128.9mg/이 in chronic alcoholics, respectively. The differences between the two groups were significant(p〈0.001 and p〈0.01). The serum HDL-cholesterol and LDL-cholesterol were 45.7$pm$10.0mg/이 and 92.2$pm$28.5mg/이 in normals and 46.6$pm$19.6mg/이 and 116.7$pm$49.8mg/이 in chronic alcoholics, respectively. The differences between the two groups were not significant. Results of this study confirms the high level of serum lipids, especially of triglyceride in chronic alcoholics.
