title: Plasma apolipoprotein profiles of male and female rats.
abstract: To determine if sex differences exist in the apolipoprotein profile of the rat, the concentrations of the major apolipoproteins and lipids of 12-week-old male and female rats were measured in the plasma as well as in the individual lipoprotein fractions. Plasma apo B, triglyceride, and cholesterol concentrations were significantly higher in male rats than in female rats. Plasma concentrations of apo A-I, apo E, apo A-IV, and apo C-III did not differ between the sexes. Male rats had higher concentrations of apo B in the very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), and the low density lipoproteins (LDL). These results further support the evidence that sex hormones influence lipoprotein metabolism in the rat.
