Plasma apolipoprotein A levels in healthy human adults.

The apolipoprotein A concentration in the plasma of ten healthy human subjects was measured immunologically on three occasions at monthly intervals and the following results recorded. 1. There was no difference between fasting and non-fasting apoprotein A concentrations. 2. Apoliportein A levels were higher in females than in males (p less than 0.001). 3. The correlation coefficient calculated for high density lipoprotein cholesterol and apolipoprotein A was 0.62. 4. The apoprotein values varied widely between subjects and ther were considerable concentration differences from month to month in the plasma of each individual.

Diagnosis of type III hyperlipoproteinemia by chromatography of plasma lipoproteins on columns containing agarose.

Agarose column chromatography has been used to separate plasma lipoproteins into very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Applied to the diagnosis of primary type III hyperlipoproteinemia, the procedure is capable of demonstrating three characteristic and specific changes from normality in the elution pattern of lipoproteins from patients with this condition. In the type III profile there is (a) incomplete separation of VLDL from putative LDL material, (b) early elution of the type III LDL with respect to a normal LDL marker, and (c) relative deficiency of type III LDL with elution characteristics of normal LDL. We advocate the use of this method in the diagnosis of type III hyperlipoproteinemia.
