Effect of acute urea loading on urinary concentrating ability and renal handling of urea. Three hundred micromoles of urea were injected (ip) just after the first 2-h urine collection (time 0). A: urinary osmolality (Uosm). B: urinary output. C: urinary urea concentration (Uurea). D: urea excretion (excr.). E: nonurea solute concentration (Unon-urea solutes). F: excretion of non-urea solutes. Values are means ± SE; n = 6. *P < 0.01 compared with wild-type mice. #P < 0.01 compared with UT-B knockout mice.
