Samples of kidney cortex, diaphragm, and atrial and ventricular muscle were taken from hamsters and ground squirrels to determine whether the low body temperature of hibernation caused loss of potassium and gain of sodium. Gradients between tissues and plasma are maintained or even increased during hibernation.
