    The disposition of inhaled lysine theophylline in volunteers (1984)

    Notizen: Summary Six healthy volunteers received an iv infusion of 317 mg lysine theophylline (equivalent to 197 mg anhydrous theophylline) in order to calculate theophylline clearance by standard methods. They subsequently received a 20 minute inhalation of nebulised lysine theophylline. Serum and salivary theophylline concentrations were measured and all saliva was collected for the first hour. From these concentrations estimates were made of the distribution of theophylline into the blood and saliva with 40% to 94% identified in the blood. Very high salivary concentrations were reached during the inhalation phase with saliva: serum concentration ratios of between 60 and 1600.

    Appearance of a novel form of plant glutamine synthetase during nodule development in Phaseolus vulgaris L. (1983)
    Springer
    Planta 157 (1983), S. 254-258

    Notizen: Abstract The activities of glutamine synthetase (GS), nitrogenase and leghaemoglobin were measured during nodule development in Phaseolus vulgaris infected with wild-type or two non-fixing (Fix-) mutants of Rhizobium phaseoli. The large increase in GS activity which was observed during nodulation with the wild-type rhizobial strain occurred concomitantly with the detection and increase in activity of nitrogenase and the amount of leghaemoglobin. Moreover, this increase in GS was found to be due entirely to the appearance of a novel form of the enzyme (GSn1) in the nodule. The activity of the form (GSn2) similar to the root enzyme (GSr) remained constant throughout the experiment. In nodules produced by infection with the two mutant strains of Rhizobium phaseoli (JL15 and JL19) only trace amounts of GSn1 and leghaemoglobin were detected.
