Effects of ionizing radiation on proteins in lyophilized or frozen demineralize...
Antebi,Uri; Mathor,Monica Beatriz; Silva,André Ferreira da; Guimarães,Rodrigo Pereira; Honda,Emerson KiyoshiOBJECTIVE: The aim was to study the effects of application of ionizing radiation (gamma and electrons) as sterilizing agents at doses of 15 kGy, 25 kGy and 50 kGy, on lyophilized or frozen demineralized bone tissue for use in transplants. METHODS: Five human femoral diaphyses from different donors of musculoskeletal tissue were demineralized and preserved as lyophilized or frozen at -80 °C. The samples were div...
