title: Effect of various lysosomes and endotoxin on vascular permeability in frogs and mice.
abstract: Blood-lymph permeability increasing effects of frog liver lysosomes, Escherichia coli 0111 endotoxin, bradykinin and serotonin were demonstrated in frogs with a method developed by the authors. These actions were expressed in a faster dye saturation in the lymph as compared to that of the controls. 2. The method is based on the determinations of concentration of Evans blue transported as protein-bound dye into the lymph. 3. Frog liver and polymorphonuclear leukocyte lysosomes had a capillary permeability increasing action tested by local skin response when injecting Evans blue intravenously in mice. 4. All these phenomena are similar to events described earlier in mammalian systems.
