TY - JOUR AU - Ciofalo, LeFran, N. AB - Abstract The urine from 40 normal healthy adults was studied before and after they were subjected to a moderate stress, that of running one mile in eight minutes or less. Special emphasis was placed on changes observed in the urinary sediment. In 95% of subjects, pronounced cylindruria occurred after the run. The casts excreted were predominantly hyaline in type, but granular casts were also frequently seen. No cellular casts were noted in any subject. The casts were studied using various light microscopic techniques, and also with the aid of a scanning electron microscope. In addition to the cylindruria, proteinuria occurred in 83% of subjects within one hour after stress. In some instances the levels of protein in the urine were detected as high as 2+ to 3+ using “dipstick” methodology. (Quantitation of these values showed ranges as high as 135 mg/dl.) These protein levels decreased gradually; at 24 hours after the run, no subject had detectable “dipstick” proteinuria.
