摘要
Several macroscopic physical properties of mineralized turkey leg tendon were measured including wet density, composition, volume fractions of the major components, sonic velocity in three axes, longitudinal modulus and dimensional changes on drying. Where possible the properties were related to density. Typically the wet density of unmineralized tissue is 1.09 g/cc, where for fully mineralized tissue it is 1.6 g/cc (compared with 2.06 to 2.10 g/cc for compact cow bone). Longitudinal sonic velocity axially is 3.22 km/sec, 2.57 km/sec transversely and 2.21 km/sec in thickness. The axial longitudinal modulus is 16.7 GPa compared to the axial Young's modulus of 8.53 GPa. MTLT shrinks 0.5% axially, 4.75% transversely and 4.15% in thickness. The anisotropy is equally exhibited in its microscopic structure when observed optically. Least squares second order curves were fitted to the water, mineral and organic component experimental values. Apparently the water in MTLT is replaced by mineral, unlike the process in bone where there is less organic matter as the mineral content increases and the water fraction changes much less. The generalized packing model for collagen was used to relate the data to the ultrastructure. The distribution of the major components between the intrafibrillar and extrafibrillar volumes as a function of the density was calculated. The results show the intrafibrillar volume fraction increases with density, the water content of the intrafibrillar volume remains almost constant, but the water fraction of the extrafibrillar volume decreases from 51 to 8% of the water in the tissue. It is concluded that the mineralization process in MTLT differs from that in bone.
