[Comparative analysis of the changes in the organic blood flow in the brain, kidneys, intestines and hindlimbs of cats as affected by adrenaline and noradrenaline].

In experiments on anesthetized cats by using the method of hydrogen clearance it was found that noradrenaline and adrenaline at doses of 0.01-10 micrograms/kg intravenously produced dose-dependent various changes in organ blood flow that were caused by differences in the action on adrenoreceptors and the degree of hypertensive reaction. The vessels of the intestine and kidneys possessed the highest sensitivity to noradrenaline and the cerebral vessels had the least sensitivity.
