Resumo
Costal cartilage has been sterilized with gamma radiation using
60Co sources at two different doses, 25 kGy and
50 kGy, for storage in tissue banks. Samples of costal cartilage were deep-freezing as method of preservation.
Thermogravimetry (Shimadzu TGA-50) was used to verify the water release of costal cartilage before and after
irradiation. The TG tests were carried out at heating rate of 10°C/min from room temperature to 600°C under a
flow rate of 50 mL/min of compressed air. Samples of costal cartilage were divided in 2 parts. One part of them
was kept as reference material; the other part was irradiated. This procedure assures better homogeneity of the
sample and reproducibility of the experimental results. The obtained data have shown that the TG curves have
the same pattern, independently of the sample. Non-irradiated samples showed great variability of
thermogravimetric curves among different donors and for the same donor. Further experimental work is being
carried out on human cartilage preserved in glycerol in high concentration (> 98%) to compare with those deepfreezing.
