Table 2 Influence of plasma lipases on the distribution of 14C-free cholesterol (FC) and 3H-phospholipid (PL) from lipid emulsions to plasma lipoproteins of hepatectomized rats in vivo.

From: Plasma lipases and lipid transfer proteins increase phospholipid but not free cholesterol transfer from lipid emulsion to high density lipoproteins.

Fractions Control Heparinized
  14C-FC 3H-PL 14C-FC 3H-PL
CM+ VLDL 61 36 47 16a
  (53 - 74) (27 - 61) (43 - 55) (14 - 22)
LDL + remnants 20 22 34b 38c
  (11 - 24) (10 - 26) (29 - 38) (33 - 42)
HDL 19 42 18 46

  1. Percent distribution of 14C-FC and 3H-PL from lipid emulsion to VLDL, LDL and HDL plasma fractions from anesthetized hepatectomized rats treated with saline (control) or heparin after 30 minutes of an intra-arterial injection of the labeled emulsion. Lipoprotein fractions were obtained by ultracentrifugation. Results are expressed as median (range), n=4. Mann-Whitney test for heparin vs. control comparisons: a: 3H-PL - CM+VLDL, p < 0.03; b: 14C-FC - LDL, p < 0.03; c: 3H-PL - LDL, p < 0.03.
