Dense collagen scar forms at the cut ends of transected nerves, and impedes nerve regeneration. To minimize scarring, we treated rats with the proline analog, cis-hydroxyproline, from day 4 to 21 after sciatic nerve transection and reanastomosis. Twenty-eight days after surgery, there was 47% less collagen in the distal nerve stump of treated rats than of controls. Seventy days after surgery, posterior tibial nerve content of the myelin lipids, sulfatide, and unesterified cholesterol, was 40% higher in treated rats than in controls.
