Values of APO-1 and APO-B in humans according to age and sex.

Two series of 100 subjects each, males and females, have been studied for the determination of plasma values of apo-A1, the major peptide of HDL, and of apo-B, the major peptide of LDL. To minimize a possible influence of variations in plasma lipid levels, two series of subjects were selected with very similar mean values of plasma cholesterol and triglyceride. Despite this criterion of selection apo-A1 was significantly lower in males (127 +/- 18 mg/l) than in females (137 +/- 15 mg/l) while the reverse was true for apo-B (99 +/- 16 mg/l in males vs. 91 +/- mg/l in females). Both apo-B and apo-A1 showed a tendency to increase with advancing age with the greatest increase for apo-A1 (in both sexes) and for apo-B (only in males) from the 3rd to the 4th decade of age.

Chemical composition of ultracentrifugal fractions in different patterns of human atheroslcerosis.

The chemical composition of ultracentrifugal fractions of VLDL (d less than 1006), LDL (d 1006-1063) and HDL (d less than 1063) has been studied in males affected by atherosclerosis of different vascular beds. Thirty-seven subjects affected by post-infarction cardiopathy (M.I.) showed significantly higher values of total-C, VLDL-C and LDL-C when compared to 52 controls. Twenty-three patients affected by non-occlusive ischaemic heart disease (I.H.D.) showed higher values than controls of total-C, VLCL-C, LDL-C, total TG, VLDL-TG, and GDL-TG. Twenty-three patients with atherosclerosis of the inferior limbs (P.A.) were characterized by increased levels of total-TG, VLDL-TG, VLDL-C, HDL-C. A group of patients who had suffered a stroke from cerebro-vascular disease (C.V.D.) did not show any significant difference from controls. In the M.I. group, 56% of the patients had a high level of C-VLDL. Patients with I.H.D. were characterized mostly by an increase in C-LDL, Patients with P.A. showed the highest values of total -TG, VLDL-TG and LDL-TG. Some of the observed differences are probably due to different metabolic backgrounds. Some other differences may be due to variations in dietary habits after heart infarction. Patients with levels of plasma cholesterol and triglyceride beyond the 90th percentile of the normal group showed many abnormalities in the chemical composition of their lipoproteins. It is noteworthy that increased amounts of cholesterol may collect in lipoprotein classes different from LDL while increased amounts of triglyceride may collect in classes different from VLDL.
