Nitric oxide metabolism in wounds.


Arginine can be metabolized in wounds to nitric oxide and citrulline by nitric oxide synthase or to urea and ornithine by arginase. We investigated the expression of these arginine metabolic pathways over a 3-week period. Groups of 8-10 male Balb/C mice underwent a dorsal skin incision and subcutaneous polyvinyl alcohol sponge implantation. The animals were… (More)
