The proteoglycan content and the axial periodicity of collagen in tendon.

摘要: The glycosaminoglycan content and the axial periodicity of collagen was determined in various regions rabbit flexor digitorum profundus tendon. This tendon, which passes from calf to toes round inner side ankle, contains a thickened sesamoid-like pad where it is subjected friction pressure. Other tendon are subject only longitudinal tension. In tensional areas order 62 nm tissue contained less than 0.2% proteoglycan on dry weight basis. region, however, significant 13-15% less, constituted about 3.5% weight. Also, predominant dermatan sulphate, whereas sesamoid chondroitin sulphate. possible interrelationships between peroidicity this discussed.
