Administration of platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine; PAF) did not alter the rate of triacylglycerol entry into the plasma. The gastrointestinal absorption of [1-14C]triolein was, however, inhibited by PAF, yet there was increased accumulation of [14C]lipid in the plasma and hypertriglyceridaemia. The half-life of injected [9,10(n)-3H]triolein in the plasma increased by 47%, and there was decreased accumulation of [3H]lipid in brown adipose tissue. This was accompanied by a decrease in lipoprotein lipase activity. The hypertriglyceridaemia induced by PAF appears to be mainly due to decreased peripheral removal, one important site affected being brown adipose tissue.
