Protective Effects of Heparin and Other Sulfated Glycosaminoglycans on Crystal Adhesion to Injured Urothelium

Abstract

Heparin prevented calcium oxalate crystal adhesion to chemically injured rat bladder urothelium. Heparin was the only polysaccharide tested which restored injured urothelium to the functional status of normal, uninjured urothelium with respect to anticrystal adhesion properties. Other sulfated glycosaminoglycans, sulfated polysaccharides and monosaccharides were without restorative or protective effects. 3H-heparin bound to injured urothelium but not to normal urothelium.
