A Calorimetric Study of Baker’s Cyst Biological Tissues

Resumo

The results of calorimetric studies of a histological preparation of a surgically excised Baker’s cyst are presented. The measurements were performed on a DSC 204 F1 Phoenix differential scanning calorimeter (Netzsch, Germany). The measurement error of the temperature dependences of the specific heat capacity of the samples analyzed did not exceed 2%. The denaturation temperature, which corresponded to the peak of the thermal signal, was 68.1°C for Baker’s cyst tissues and the denaturation enthalpy was 4.352 J/g. No thermal effects were observed on the thermograms when the samples were re-scanned; this is indicative of irreversible changes related to complete denaturation of collagen in the samples.
