title: The anticollagenolytic potential of lymecycline in the long-term treatment of reactive arthritis.
abstract: OBJECTIVE
  We sought to determine the antiinflammatory properties of lymecycline in the long-term treatment of reactive arthritis (ReA).
  
  
  METHODS
  Quantitative assay of collagenase activity by densitometry after sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
  
  
  RESULTS
  Therapeutic levels of lymecycline do not directly inhibit the activity of human neutrophil interstitial collagenase, but can prevent the oxidative activation of latent human neutrophil collagenase.
  
  
  CONCLUSIONS
  This non-antimicrobial, anticollagenolytic property of lymecycline may contribute to its therapeutic efficacy in the treatment of patients with ReA.
