Abstract:
Circadian rhythms of the substances related to lithogenesis such as volume, pH, creatinine, calcium, magnesium, uric acid, phosphorus, citrate and oxalate in urine of 10 healthy men who led method of urine sampling at 2 hours interval from 6 :00 were evaluated to midnight and a 6 hours : The urine volume, pH, excretory amounts and concentration of calcium, magnesium, uric acid, citrate and oxalate except creatinine and phosphorus in 24-hour fractionated urine were shown to increase during postprandial period between 8:00 and 10:00 and between 22:00 and midnight. The creatinine excretion was minimal variations in all fractionated urine. The phosphorus excretion was modestly pronounced about dinner, but low value between 10:00 and noon. Therefore, almost lithogenic and inhibitory substances in urine were relatively increased after breakfast and dinner so that lithogenesis were thought to be intimately concerned with diet.
