Abstract
Summary
The vascular response of the perfused isolated dog kidney to acute periods of hypothermia has been carried out in specially designed experiments to remove interfering vascular effects of altered blood viscosity and extravascular pressure. Results show an active renal vasoconstriction occurring during the rewarming period, resulting from the release of adrenergic agents by the stressed animal. It is concluded that both active and passive components of renal resistance are involved during certain phases of hypothermia.
