Thermal analysis of rat bone tissue.
The paper describes thermoanalytical data obtained from rat limb bones by TG, DTG and DSC. Analyses were performed on bone samples from femurs, tibiae and humeri, either crude and extracted with acetone and/or sodium dodecylsulphate. The DSC curves show an endothermic reaction at 85 degrees C and a sharp exothermic peak at 337 degrees C, followed by an exothermic profile between 350 degrees-650 degrees C. Mean weight changes are: 34.28% total weight loss (25 degrees-800 degrees C); 7.33% water loss (25 degrees-200 degrees C); 26.21% organic loss (200 degrees-800 degrees C). Thermal analysis on diaphyseal and epiphyseal bone samples evidences an organic content of 24.54% for diaphyseal compact bone tissue and of 30.62% for epiphyseal trabecular bone tissue (p < .005). The values obtained from different bones and by different treatment of samples are compared.
