          Abstract

          Des microinjections d’une solution contenant du <sup>24</sup>Na et de I’inuline <sup>14</sup>C ont été effectuées dans des anses capillaires de la papille du rein, chez le hamster en diurèse saline. L’excretion des indicateurs a été étudiée dans I’urine urétérale en fonction du temps. Dans les 16 expériences pratiquées on observe une excrétion de <sup>24</sup>Na notable (en moyenne 6% de la dose), relativement constante et précédant I’excrétion d’inuline <sup>14</sup>C; de plus, cette excrétion de <sup>24</sup>Na est absente dans I’urine du rein controlatéral (3 expériences). L’excrétion de sodium observée traduit un passage direct à travers les parois d’un segment médullaire des néphrons possédant une très haute perméabilité au sodium; qualitativement, ces résultats permettent de localiser ce segment le long des anses de Henle (probablement leur segment grêle); quantitativement, ils semblent compatibles avec un échange complet entre les ions sodium de I’urine intratubulaire et du milieu interstitiel de la medulla.
