“…Only when these conditions are met can the extent and the rate of drug (or metabolite) transfer be defined quantitatively. The methods developed for the dog (8) have been adapted for patients (86), sampling lumbar rather than cisternal fluid. Steady-state ratios and transfer rates were established for antipyrine, sulfadiazine, and p-aminohippurate.…”

“…Die Theorie über die Diffusion nicht ionisierter Substanzen besagt, daß Membranen wie die Zellwand und die Blut-Liquor-Schranke nur für die Diffusion nichtionisierter Stoffe permeabel sind. Deshalb ist die Verteilung solcher Substanzen zwischen den durch eine solche Mem bran getrennten Räum en vom pH-Gradienten und von der Dissozia tionskonstanten der Substanz abhängig [5,7,8].Für das Ammoniak bedeutet das, daß das nichtionisierte N H S vom alkalischen in das saure Milieu diffundiert. Entsprechende Untersu chungen zeigten, daß das Ammoniak unter experimentellen Bedin gungen tatsächlich diesen Gesetzmäßigkeiten folgt [3,4,6,9].…”
