THE GASEOUS METABOLISM OF THE DOG'S KIDNEY

Abstract

The apparent O metabolism of the kidney was estimated in 9 dogs by the method of Barcroft and Brodie. The oxygen consumption varied from 0.009 to 0.113 cc. per gm. per min., the higher figures usually accom-panying the greater blood flow and more profuse diuresis. The injection of urea, caffeine, Na2SO4, or certain drugs was not followed by any characteristic effect on apparent O metabolism. In 2 kidneys perfused with constant blood flow diuresis induced by caffeine or Na2SO4 was not accompanied by an increase in the amount of O disappearing from the blood per min.
