15 صفحه اولEquality of the in vivo and in vitro oxygen-binding capacity of haemoglobin in patients with severe respiratory disease.
The in vivo and in vitro oxygen-binding capacity of haemoglobin was determined on 10 occasions in nine patients who required mechanical ventilation. The in vitro sample was tonometered with 97% oxygen for 10 min and then with air, while the in vivo sample was obtained after 20 min of lung ventilation with pure oxygen. Subsequent laboratory procedures were identical for both samples. The mean ox...
متن کاملChemical Nature of the Oxygen-transferring Ferment of Respiration in Plants.
The effect of carbon monoxide on the respiration of animal cells and aerobic bacteria (10), and on anaerobic butyric acid fermentation (6), has shown that the ferments which act as catalysts in these energy-yielding cellular processes are compounds of heavy metals: for carbon monoxide reacts at low temperatures only with heavy metals, and respiration as well as anaerobic butyric acid fermentati...
متن کاملHaemoglobin, oxygen carriers and perioperative organ perfusion.
Under normal conditions, only 20-30% of the delivered oxygen is metabolised. In normovolaemic anaemia, the organism reacts with increases in cardiac output and oxygen extraction. Once these mechanisms are exceeded, allogeneic blood transfusions may be administered. However, such transfusions are associated with serious adverse effects and alternatives such as artificial oxygen carriers are bein...
متن کاملThe Oxygen Affinity of Haemoglobin in Splenectomized Bullfrogs
EVIDENCE obtained from previous studies suggests that one of the factors which influence the affinity of amphibian haemoglobin for oxygen is the locus of erythrocyte formation (Barcroft, 1934; Hall, 1934). It has been shown for the developing bullfrog (McCutcheon, 1936), and also for different species of the class Amphibia (McCutcheon & Hall, 1937), that the oxygen dissociation curve shifts fro...
