[Changes in the filtration-absorption equilibrium in the lungs in response to electrolyte hemodilution]

Abstract

I. v. administration of lactasole increased the capillary filtration coefficient, precapillary resistance and the pressure in the lung artery in anesthetized cats, the capillary hydrostatic pressure and the blood flow diminishing in these conditions. I. v. administration of the Ringer solution increased the capillary filtration coefficient and postcapillary resistance; no shifts of the capillary hydrostatic pressure, precapillary resistance, blood flow or arterial pressure, were found. Possible mechanisms of effects of the hemodilution with above solutions on the filtration-absorption balance in the lungs, are discussed.
