[Effect cold adaptation to the ouabain-sensitive component of kidney respiration in rats]

In the course of intermittent cold adaptation (0 degrees C, for 16 weeks) the rats demonstrated an increase in the rate of oxygen consumption by a suspension of kidney pieces. The increase of oxygen consumption by 60% is ouabain-sensitive. Together with the data on Na, K-ATPase activation this indicates the main role of the Na-pump in the increased respiration of the kidneys on cold adaptation.
