The author measured the value of serum triglyceride, total cholesterol and phospholipid in normal Korean adults and patients with complicated hypertension.

Sera obtained from 295 cases of normal Korean male and female, and also 109 cases of patients with hypertension were analysed for triglyceride, cholesterol and phospholipid. The patterns of serum lipoprotein fraction in 171 normal Korean and 109 patients with complicated hypertension including cerebrovascular diseases and ischemic heart disease were studied by agarose gelelectrophoresis.

The results are summarized as follows;

1. The mean value of serum triglyceride, cholesterol and phospholipid in normal Korean were 85.4±20.5mg%, 187.9±16.7mg%, and 193.4±34.6mg% respectively.

2. Sex and age difference showed no statistical significance in the mean values of serum triglyceride, cholesterol and phospholipid in hypertensive patients.

3. The mean values of serum triglyceride in the patients with complicated hypertension such as cerebral thrombosis gave higher value than in the patients with other cerebral complications.

4. The mean value of α-lipoprotein, pre-β-lipoprotein and β-lipoprotein in normal Korean were 29.6±5.0% (142.6±30.1mg%), 13.0±4.3% (62.7±24.8mg%), and 57.4±30.1% (276.1±56.6mg%) respectively.

5. The α-lipoprotein fraction in normal Korean demonstrated the tendency of decreasing as age is progressing in both sex, but pre-β and β-lipoprotein fraction gave a tendency of increasing by progressing age in both sex, but was not confirmatory in nature.

6. The α-lipoprotein fraction in patients with hypertension gave lower value than in the normal subjects, but the value of pre-β and β-poprotein were elevated significantly among patients with complicated hypertension than in normal person.

7. The incidence of hyperlipidemia in normal Korean and patients with hypertension were 31.9% and 66.5% respectively.

8. The relative incidences of hyperlipidemic probable phenotypes in normal Korean were as follows: 7% of normal person had Type II (IIa 3.3%, IIb 3.7%), 3.5% had Type III, and 21.4% had Type IV.
