[Effect of experimental hypokinesia on adrenergic reactivity of the cardiovascular system in rabbits]

In the experiments on rabbits under prolonged hypokinesia the functions of the cardiovascular system and the adrenergic reactivity of blood pressure were studied. The increase of the heart rate at rest, clear tendency to the decrease of the arterial blood pressure and no changes of the venous pressure are shown. The reliable decrease of the maximum size and duration of the blood pressure reactions to adrenaline are demonstrated. These changes prove the decrease of the functional possibilities and adrenergic reactivity of the cardiovascular system under hypokinetic conditions.
