Abstract
The cross-links from NaB3H4-reduced bone collagen of chronically uraemic rats and pairfed controls were compared. The ratio of the reduced cross-links deltadelta'-dihydroxylysinonorleucine to delta-hydroxylysinonorleucine was significantly increased in the uraemic animals. The observed increment in the dihydroxylysinonorleucine:hydroxylysinonorleucine ratio was accentuated as the uraemic state advanced. The data indicate that osteodystrophy of chronic renal insufficiency is characterized by an alteration of the quantitative relations between cross-links and aldehydic precursors of bone collagen.
