摘要：
H-1-NMR was used to monitor concentration of dimethyl sulfoxide in articular cartilage on patellae from pigs as a function of time and temperature. The resulting diffusion coefficient was 1.12x10(-5).cm(2)/sec at 23 degrees C with an Arrhenius activation energy of 0.95 kcal/mol. Concentration profiles in cartilage of various thicknesses were calculated as a practical aid for the design of protocols to cryopreserve articular cartilage.
