title: [Circadian rhythms of urinary parameters in children with glomerulonephritis].
abstract: Circadian rhythms of urinary parameters were studied in healthy children and those with glomerulonephritis. In healthy children, urinary excretion of many substances rhythmically varied during a day. Variations were related to the volume and specific gravity of urine, to the levels of creatinine, MDA, and SOD activities. Children with glomerulonephritis showed changes in values of circadian rhythm of urine parameters. These disorders included changes in circadian variations and mean daily values, inversion of group and individual excretion patterns, which indicates that there is an external and internal disagreement of biological rhythms in children with glomerulonephritis.
