Resumo
Records of the electrical impedance were obtained by means of surface electrodes placed on ventral and dorsal sides of the left kidney of anesthetized dogs. Changes of the renal electrical impedance resulted from alterations of the glomerular filtration rate caused by decrease of blood renal pressure to 80 and 50 mm Hg either due to constriction of the aorta or bleeding. The relation was established also by using physiological infusion. The results showed that changes of the means of renal electrical impedance were in opposite direction to changes in glomerular filtration rate. The electrodes employed were constituted of two parts: one fixed and another adjustable and flexible, allowing good contact with the renal surface independent of the kidney size.
