title: The removal of exogenous triglycerides in haemorrhagic hyperlipidaemia in rabbits.
abstract: Bleedings (15 ml/day/kg b.wt.) on two consecutive days caused a threefold increase in plasma triglycerides (TG) in rabbits. Both in normal and in haemorrhagic rabbits the elimination of injected TGs (fat emulsion) was exponential, the fractional removal rate in the haemorrhagic group being slower than normal. In order to rule out the possible effect of the TG pool in haemorrhagic rabbits and the possible changes in endogenous TGs during the test, the TGs were fractionated by the polyvinylpyrolidone density gradient method. Again, both in normal and in haemorrhagic rabbits the elimination of exogenous TGs was exponential, the removal rate of haemorrhagic animals being retarded. Accordingly, the changes in endogenous TGs were negligible. The results are regarded as indicative of an elimination defect as one factor in the pathogenesis of haemorrhagic hyperlipidaemia.
