Although mammalian urinary tract epithelium (urothelium) is generally considered impermeable to water and solutes, recent data suggest that urine constituents may be reabsorbed during urinary tract transit and storage. To study water and solute transport across the urothelium in an in vivo rat model, we instilled urine (obtained during various rat hydration conditions) into isolated in situ rat...

There is abundant evidence that glycosaminoglyeans are linked covalently to the protein in tissues (Mathews & Lozaityte, 1958; Muir, 1958). This fact suggested that isolation and characterization of glycosaminoglycan-peptides, particularly uronic acid-containing glycopeptides in normal urine, will assist in the understanding of the normal metabolism of glycosaminoglycans in tissues. The present...
