Oxygen consumption in skeletal muscle during reactive hyperemia.
Igo-192. rggg.---The surgical technique of isolation of the blood supply of the gracilis muscle of the dog has been developed for analysis of the oxygen consumption during reactive hyperemia. The time course of the blood flow, A-V oxygen difference and the oxygen consumption follow the same pattern. Immediately after the release of the arterial occlusion, there is an increase in all three value...

متن کاملLow Po₂ conditions induce reactive oxygen species formation during contractions in single skeletal muscle fibers.
Contractions in whole skeletal muscle during hypoxia are known to generate reactive oxygen species (ROS); however, identification of real-time ROS formation within isolated single skeletal muscle fibers has been challenging. Consequently, there is no convincing evidence showing increased ROS production in intact contracting fibers under low Po₂ conditions. Therefore, we hypothesized that intrac...

Physiol. 224(4) : 763-768. 1973.-In isolated, autoperfused preparations of the cat soleus (n = 10) and gracilis (n = 9) muscles, blood flow and venous and tissue Po2 were measured at several levels of perfusion pressure. Oxygen consumption (Vo2, steadystate conditions) de...
