Emulsions of polystyrene latex particles of 2200 A size were administered to rats in food and by stomach tubes. Electron microscopic study of jejunum, liver, and kidney showed the latex particles were picked up by intestinal epithelium, carried through the cytoplasm within intact vesicles, discharged into the interstices of the lamina propria, and entered the lymphatics of the mucosa. The process was identical with that previously shown for lipid particles. The latex particles were also demonstrated in the lumen of glomerular capillaries, in the hepatic sinusoids, in the spaces of Disse of the liver, and in the process of being taken into the liver cells by pinocytotic vesicles at the cell membrane. The value of latex particles of known size in the study of body processes of handling submicroscopic particles was thus demonstrated. Further evidence was gained for the significant role of the liver in removing particles of this general size range from the bloodstream.
