title: [Functional load tests for the investigation of the kidneys and water-electrolyte metabolism].
abstract: The paper deals with the application of functional load tests to assess the renal function and water-salt metabolism in human subjects during spaceflight simulating experiments and in cosmonauts in orbit and in the course of postflight recovery. The tests gave insight into mechanisms of the osmotic and volumetric regulation systems and enabled the development upon this knowledge of countermeasures to correct shifts in water-salt homeostasis.
