title: Urinary volume, creatinine and thiocyanate of Africans of a tropical savanna region.
abstract: For 130 healthy African subjects of savanna region, the 24 h urine output was found to be of the order of 1000 ml. This appears somewhat less than levels found among temperate region peoples. These results permit one to grossly evaluate 24 h excretion of substances on rapid field studies. The creatinine urine excretions found, confirm the known characteristics--the variability with age, sex and amount of muscular tissue. Further the 24 h excretion cannot be accurately measured when one calculates it on the basis of urine creatinine excretion of a single micturition; therefore for an accurate measure one needs controlled 24-h urine collections. The urine thiocyanate excretion of this non-goitrous population on a low cassava diet is significantly lower than that found in an endemic goitrous population.
