A method is described for determining the rate of mechanical expression and resorption of fluid from cartilage and for determining its composition. Human articular cartilage, unlike costal tissue, showed little change in its total or expressible fluid throughout life. The extruded material resembled synovial fluid except for its low protein content and viscosity. It is suggested that the expressed fluid was held osmotically in the ground substance.

Es describite un methodo pro determinar le valor del mechanic expression e resorption de liquido ab cartilagine e pro observar su composition. Human cartilagine articular—per contrasto con tissu costal—monstrava in le curso del vita pauc alteration in su total de exprimibile liquido. Le exprimite material resimilava liquido synovial, excepte que illo habeva un basse contento de proteina e un basse viscositate. Es proponite le these que le exprimite liquido esseva retenite osmoticamente in le substantia de base.
