title: [Effect of cyclic nucleotides and isopropylnoradrenaline on oxygen tension and absorption].
abstract: Isopropylnoradrenaline (ISO), 3',5'-AMP and dibutyryl-3',5'-AMP decreased the oxygen tension (pO2) in the liver and the spleen and increased the body oxygen consumption (VO2). Time dynamics of these two effects was closely correlated for ISO and 3',5'-AMP. An increase of heat output was not accompanied by any significant changes in the respiration coefficient. Pempidine and dihydroergotamine failed to prevent 3',5'-AMP effects; inderal somewhat decreased these effects. Apparently, the catecholamine influence upon pO2 was a result of the VO2 increase through 3'5'-AMP effects are largely direct, but they include the in vivo and beta-receptor component; 2',3'-AMP decreased pO2 and VO2.
