    Notes: Summary The effect of cholestyramine on the absorption of phenprocoumon and acetylosalicylic acid has been studied in volunteers by comparing their serum concentrations after a single oral dose either of the drug alone or simultaneously with the resin in a crossover repetition arrangement. In four volunteers cholestyramine 8 g significantly reduced the absorption of a simultaneous 15 mg dose of phenprocoumon. The effect of the latter on coagulation, as measured by the thrombotest method was also diminished. The absorption of acetylosalicylic acid 500 mg was delayed by cholestyramine but there was no appreciable effect on the total amount absorbed. These results are in accordance with the stronger binding of phenprocoumon to cholestyramine inin vitro experiments.

    Optical pumping of ions in buffer gases (1972)

    Notes: Abstract A method for polarizing thermal ions in buffer gases directly by optical pumping is presented in detail. The production and storage of Sr+ (and Ba+) ions in noble gases, their diffusion and relevant collision processes are discussed. An arc discharge hollow cathode for the generation of intense ionic resonance lines is described. The Sr+ (52 S 1/2) and electron spin polarizations are treated by rate equations. Fitting the solutions to experimental data obtained from transient signals yields an estimate of a few times 103Å2 for the Sr+ion-electron spin exchange cross section.
