title: Effect of indomethacin and naproxen on collagen cross-linking.
abstract: The influence of indomethacin and naproxen on rat dermal collagen cross-linking was investigated in vivo. The analyses of skins showed that the naproxen group had a decrease in percent reversibility of neutral salt-soluble collagen gel, susceptibility of insoluble collagen to denaturing agents and pronase and alpha/beta ratio of neutral salt-soluble collagen whereas the aldehyde content was significantly increased. Indomethacin was ineffective for all these parameters. The results indicated that both the inter and intra-molecular cross-linking of collagen was increased in the naproxen treated group while indomethacin did not influence the collagen cross-linking.
