| Research Abstract |
The myocardium that is the muscle of the heart has repeated contraction and relaxation continuously. In order to reveal the action of the volatile anesthetic to the microvessel which supplies blood to the myocardium, we sliced the cardiac muscle of the rat and observed the myocardial microvessel how vessel diameter would change under the influence of vasoactive drugs and volatile anesthetics. Although the capillary vessels in a myocardium showed the contraction under the vasoconstrictor drug, the stable relaxation response by a vasodilator drug was not observed. It was thought that the method of study was unsuitable.
