title: [Change in local blood flow in the kidney cortex of the rabbit in prolonged hypotension].
abstract: The local blood flow in the renal cortex was studied on rabbits of the puberty age by means of the hydrogen clearance method during a prolonged bleeding. It has been established that at the beginning of bleeding the changes of systemic arterial pressure and the cortical blood flow of the Kidney have the same direction, though reduction of the latter passes ahead of the reduction of arterial pressure, which indicates the centralization of blood circulation. During the reduction of the systemic arterial pressure to 32-53% of the normal level equilibration a stabilization of the renal blood flow was observed. Microcirculation in the renal cortex ceases when the arterial pressure is 20-25 mm Hg/min.
