It was shown in experiments on cats anesthesized with nembutal that sodium hydroxybutyrate given in doses of 100 and 200 mg/kg increases the coronary blood flow in the intact myocardium. At the same time oxygen consumption by the heart rises to a far less degree. The drug provokes negligible hypertension, raises the systolic and cardiac outputs, and enhances myocardial contractility. It was discovered in experiments on dogs with the ischemized heart that sodium hydroxybutyrate in a dose of 200 mg/kg increases the blood supply both to the intact and ischemized myocardium areas. Changes in myocardial ischemia duration and in the hemodynamics produced by sodium hydroxybutyrate are similar to those caused by the drug in experiments with the intact heart.

D010101 Oxygen Consumption The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346) Consumption, Oxygen,Consumptions, Oxygen,Oxygen Consumptions
D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
