Studies of myofibrillar ATPase in ragweed-sensitized canine pulmonary smooth muscle

The maximal shortening velocities of tracheal and pulmonary vascular smooth muscle from ragweed-sensitized dogs were significantly higher than those of muscles from their littermate controls. Myofibrils of tracheal and pulmonary vascular smooth muscle from ragweed-sensitized and control dogs were ob...

Summary:The maximal shortening velocities of tracheal and pulmonary vascular smooth muscle from ragweed-sensitized dogs were significantly higher than those of muscles from their littermate controls. Myofibrils of tracheal and pulmonary vascular smooth muscle from ragweed-sensitized and control dogs were obtained with use of Triton X-100 homogenizing solution. The myofibrillar adenosinetriphosphatase (ATPase) activities of the sensitized tissues were significantly higher (P less than 0.05) than those of their respective controls.
