    Description / Table of Contents: Summary Glucose reabsorption was studied at different perfusion rates in the single perfused proximal nephron of the rat. At normal plasma glucose levels diffusion of glucose from peritubular blood to tubular fluid is negligible. Per unit tubular length an increment in glucose reabsorption can be demonstrated with increments in perfusion rate. There is a close correlation between this increment in glucose reabsorption and the net reabsorption of water.
    Notes: Zusammenfassung Mit Hilfe der Mikroperfusionstechnik wurde die Glucoseresorption an einzelnen proximalen Tubuli der Rattenniere in situ bei verschiedenen tubulären Perfusionsstromstärken untersucht. 1. Bei normalen Glucosekonzentrationen im Plasma gibt es keine nennenswerte Rückdiffusion von Glucose aus dem peritubulären Raum in die Tubulusflüssigkeit, so daß bei der Bestimmung der Glucoseresorptionsrate dieser Faktor zu vernachlässigen ist. 2. Eine Änderung der Stromstärke in den perfundierten proximalen Tubulussegmenten führt zu einer gleichsinnigen Änderung der Glucoseresorptionsrate. 3. Es besteht dabei eine lineare Korrelation der Glucoseresorptionsrate zur Nettoresorption von Wasser.

    Notes: 14C-tagged triphenylmethyl hexachloroantimonate was used to initiate the polymerization of THF. An activity count on the polymers indicated no incorporation of initiator fragments into the macromolecule. On ascertaining the fate of the tagged trityl fragment it was found that the activity resided in the triphenylmethane isolated from the methanol supernatant. This indicates that at least one sequence of the initiation reaction in this polymerization involves hydride ion abstraction.
