Phagocytosis of Colloidal Carbon in a Lymph Node

摘要: Colloidal carbon, injected intramuscularly, migrates rapidly and selectively to a corresponding lymph node by lymphatics, in which the carbon travels as free particles. In node, particles are mainly phagocytosed stored macrophages, exhibit morphologic changes plasma membrane tubules of endoplasmic reticulum. The subsequent migration these cells results wide distribution node. Cytoplasmic also occur sinusoidal no is seen. A possible relation macrophages macrophage postulated. lymphatic endothelial cells, like any other organ, phagocytose only small amount after functional overload macrophages.
