Abstract

The effects of 12 weeks eicosapentaenoic acid (EPA) administration (2.7 g/day) on plasma lipoprotein subfraction levels and on activities of lecithin: cholesterol acyltransferase (LCAT) and lipid transfer protein (LTP) were investigated. Plasma VLDL-C, VLDL-TG, VLDL-PL, VLDL-apo B, VLDL-apo C-II and VLDL-apo C-III levels were decreased by 32.8% (P less than 0.05), 31.2% (P less than 0.01), 31.5% (P less than 0.05), 32.5% (P less than 0.05), 34.7% (P less than 0.05) and 34.1% (P less than 0.05), respectively. EPA did not change plasma IDL-TC, IDL-TG, IDL-PL and IDL-apo B levels. Plasma large, light LDL (LDL1)-TC, LDL1-PL and LDL1-apo B levels were decreased by EPA by 18.7% (P less than 0.02), 19.1% (P less than 0.01) and 23.3% (P less than 0.01) while LDL1-TG level was not changed. Plasma small, heavy LDL (LDL2)-TC level was increased by 25.7% (P less than 0.02) while LDL2-TG, LDL2-PL and LDL2-apo B levels were not altered. Plasma HDL2-TC, HDL2-TG, HDL2-PL and HDL2-apo A-I levels stayed unchanged by EPA treatment. EPA did not affect plasma HDL3-TC, HDL3-PL and HDL3-apo A-I levels but decreased HDL3-TG level significantly (P less than 0.02). LCAT activity was not altered by EPA. LTP activity was increased by 24.8% at 4 weeks (P less than 0.02) and by 32.1% (P less than 0.001) at 12 weeks EPA treatment. We conclude that EPA reduces plasma large, light LDL levels as well as plasma VLDL amounts and stimulates LTP activities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
