Three-Dimensional Organization of Lymphatics in the Dog Stomach: A Scanning Electron Microscopic Study of Corrosion Casts

摘要: The three-dimensional organization of the lymphatics in dog stomach was studied by scanning electron microscopy corrosion casts, which were made direct parenchymal injection low-viscosity Mercox-resin into mucosa and muscular layers. Although has been a variety methods, origin their connection each layer not clearly defined. In this study, using because its structural similarity to human stomach, we defined lymphatic structure all gastric layers, with absent upper two-thirds lamina propria mucosae. They first encountered at deepest level propria, immediately above muscularis These composed single-layered irregular meshes. Slender arising from network passed through is mucosae drained plexus, thicker uppermost submucosa. Lymphatic valves frequently seen plexus. From slender connecting extended straight downward without lateral communications plexus This latter large-caliber lymphatics, issued flattened formed layer. subserosal thick tortuous courses efferent lymphatics.
