title: Collagenolytic activity of carrageenin granuloma in rats.
abstract: Collagenolytic activity at various phases of the development of carrageenin granuloma was investigated by measuring the amount of dialysable hydroxyproline formed during incubation in vitro of minced granulation tissue. Collagenolytic activity reached a maximum at day 8 after carrageenin injection and then decreased gradually, while collagen synthetic activity was rapidly decreased from day 4 to day 11. The significance of dialysable hydroxyproline in native collagen breakdown of carrageenin granuloma is discussed.
