Abstract:
Cold-provoked intensification of oxygen consumption was correlated with individual radioresistance of mice. There was a positive correlation between the parameters in normoxia and hyperoxia, and a distinct negative correlation in hypoxia. Radiosensitizer of hypoxic cells, metronidasol, severed the correlation no matter what level of oxygenation in the course of irradiation. The hypothesis for intracellular pO2 as a mediator of the dependence of individual radioresistance on the gas exchange reactivity has been put forward.

Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves the...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
