Abstract We analyzed correlations between apolipoprotein B (apo B), cholesterol and phospholipids (preponderant lipids) in low-density lipoproteins (LDL) as well as between apolipoprotein A1 (apo A1) and these same lipids in high-density lipoproteins (HDL), during the acute phase of myocardial infarction. In LDL, a very elevated and stable correlation (r) was observed between these parameters, and the coefficients of regression (b) did not differ significantly during the period studied. In HDL, there was a decrease in r and b values from day 1 to day 2, then an increase after day 2. We hypothesize that these disturbances in HDL composition may be due to a greater endocytosis of LDL at day 2, leading to intracellular increase in cholesterol and phospholipids. Part of these lipids could be taken up by HDL molecules, causing a transient overload.

Low density human plasma lipoproteins Sf 17+, Sf 13, and Sf 6, high density lipoproteins 2 and 3, and a lipoprotein-free plasma protein fraction were isolated from human plasma by ultracentrifugal methods. It was found that human plasma lipoproteins are immunochemically distinct from the non-lipoprotein containing plasma protein fraction. Lipoprotein fractions of a given hydrated density, isolated from different individuals, were found to be immunochemically indistinguishable by qualitative absorption tests. Qualitative antigenic differences were shown to exist between low density lipoproteins and high density lipoproteins. Quantitative precipitin reactions showed that low density lipoproteins Sf 6 and Sf 13 were immunochemically very similar. However, they differed with respect to the amount of antigen nitrogen required for maximum precipitation. Agar diffusion analyses were performed; the results suggest heterogeneity of lipoproteins by this criterion.
