Summary

The effects of orthostatic changes on the excretion of urokinase were studied in healthy normal volunteers. Urokinase excretion rose (average +69%) significantly (p<.005) while urine volume fell (average–59%) significantly (p <.001) after the subjects had been standing. There was no difference between men and women nor was there an apparent diurnal variation in urokinase excretion of recumbent subjects. A relationship between urokinase excretion and sympathetic nervous system activity is suggested.
