Abstract Intravenous injection of a reacting dose of horse serum (2 ml/kg) into sensitized rabbits and dogs was followed by lowering of the blood pressure in the main arteries and by slowing of the blood flow, disturbance of the laminar pattern of flow, aggregation of the blood cells, and blood stasis in the terminal segments of the pial vessels. The arterioles and venules were dilated. After injection of a smaller reacting dose of serum (1 ml/kg) into rabbits, elevation of the blood pressure in the main arteries, acceleration of the blood flow in the pial vessels, and spasm of the arterioles and venules were recorded initially, followed by a fall of blood pressure, dilatation of the arterioles and venules, and the development of the microcirculatory disturbances described above.
