Ultracentrifugal analysis of the plasma of squirrel monkeys at various times after the injection of [Me-14C]choline revealed the specific activities of lecithin in both high (HDL) and low (LDL) density lipoproteins to be similar. This was also true f

The concentration of lysophosphatidylcholine (monoacyl sn-glycerol 3-phosphorylcholine) in intima plus inner media of atherosclerotic aorta from squirrel monkeys was nearly eight times that in comparable control tissue. Plasma levels of the same comp

We have studied the effect of long-term hyperlipemia and atherosclerosis in squirrel monkeys on the metabolism of lysolecithin-14C (1-palmitoyl-1′-14C sn-glycerol 3-phosphorylcholine) in order to explain elevated plasma and arterial concentrations

Lysolecithin concentrations in the aortic intima plus inner media are greatly increased with atherosclerosis in squirrel monkeys, and with the associated hyperlipemia more than half of plasma lysolecithin is found in the lipoproteins. To explain thes

The effects of two forms of early deprivation on the compo sition of neural tissues were assessed. Female rhesus monkeys (Macaca mulatta) were fed a low protein diet prior to conception or from gesta- tional day 50 until the infants were delivered by

Primary cultures of rabbit hepatocytes were incubated with rabbit high density (HDL) and low density (LDL) lipoproteins in order to compare the surface transfer of free cholesterol with the uptake of apoproteins. Hepatocytes were maintained for vario

We studied the metabolism of different classes of lipoprotein in squirrel monkeys and rabbits. Lipoproteins were labeled in vivo in donor animals with [ 3 H]leucine and [ 3 H] cholesterol. The rate of disappearance from plasma of recipient squirrel m

To explore the effect of the type of dietary fat and the level of cholesterol on the rate of cholesterol absorption, 13 different male squirrel monkeys were used for 39 different tests. The plasma isotope ratio technique of Zilversmit, which involved

Primary cultures of rabbit hepatocytes which were preincubated for 20 h in a medium containing lipoprotein-deficient serum subsequently bound, internalized and degraded 125I-labeled high-density lipoproteins2 (HDL2). The rate of degradation of HDL2 w

We studied plasma lipoprotein and hormone concentrations in rhesus monkeys that had consumed either a low protein (3.8% of kilocalories) or a control protein (13.9%) purified diet since birth (6-10 yr before the beginning of this experiment) in order
