【 摘 要 】

The size distributions of electrophoretically isolated subfractions of the very low density human plasma lipoproteins have been determined using electron microscopy. The primary and secondary particles observed in plasma of normal subjects after fat ingestion appear to have similar size distributions. Particles produced by corn oil feeding can be fixed by the osmium tetroxide reaction while those produced by butter fat feeding could not be fixed or made visible by this technique. Good agreement between particle size as measured by electron microscopy and particle size as predicted by ultracentrifugal analysis was obtained.
