title: [The cell number in spontaneous uncentrifuged urine].
abstract: The leucocytes and erythrocytes in spontaneous urines were determined in the counting chamber at native and experimentally reduced pH values after standing for various periods. The pH value remained constant for up 6 h, whereby the disintegration of cells increases with rising pH values. The investigations do not rule out a circadian rhythm of cell excretion referring to the quantity of cells/time. Depending on the absolute number of cells the methodic variation coefficient lies between 4 and 25%.
