Abstract
Amount of creatinine in the 24-hour urine was measured in healthy children, during normal time and after administration of a drug, and it was found that there was almost no variation in the value. Amino-nitrogen and glucuronic acid in the urine were measured after administration of sodium glutamate in healthy children and variation in creatinine ratio in both cases was examined. The ratio tended to increase after administration but the value gradually returned to the original with passage of time.
