Auswirkungen der renalen Insuffizienz auf die Zusammensetzung der Cerebrospinalflüssigkeit, den Stoffwechsel des ZNS und zentralnervöse Funktionen

A method is described for the determination of urea in plasma and urine. The effects of variations in the experimental conditions are examined and the results of recovery experiments and other tests of precision and accuracy are reported. In comparison with other methods in current use, this method has distinct advantages in sensitivity, simplicity, and precision, thus economizing in time, sample volume, reagents, and equipment.
