摘要: The blood clearance and organ deposition of polystyrene and cellulose (DEAE) particles have been studied in the rabbit using labelled material and the technique of gamma scintigraphy in order to investigate the importance of particle size, shape and nature. Small (1.27 μm diameter) polystyrene microspheres were taken up by the reticuloendothelial system of the liver, while large polystyrene particles (15.8 μm diameter) were mechanically filtered by capillary beds of the lungs. Cellulose microspheres and fibres were also taken up …
