Taking advantage of the osteoinducing properties of the osseous matrix and glycerin as a proper medium for tissue preservation, osseous matrix was implanted in rat tibias. Twenty-four rats were used, each receiving two surgical wounds. In one of the wounds an osseous matrix preserved in 98% glycerin was implanted and the other received a matrix without preservatives. Six animals were sacrificed on days 10, 20, 30 and 60 post-implant. After routine histological processing, the specimens were stained in hematoxylin-eosin and Masson's trichrome. The results showed that the matrixes preserved in glycerin presented faster resorption with replacement by newly formed tissue.79-87engazo compoundcollagencoloring agentdiagnostic agenteosinfluorescent dyeglycerolhematoxylinmethyl greenpreservativeallotransplantationanimalbone developmentbone matrixconnective tissuefibroblastfollow upmaleosteoblastosteolysispathologyphysiologyrattibiatissue preservationtransplantationtrichrome stainWistar ratAnimalsAzo CompoundsBone MatrixBone ResorptionCollagenColoring AgentsConnective TissueEosine Yellowish-(YS)FibroblastsFluorescent DyesFollow-Up StudiesGlycerolHematoxylinMaleMethyl GreenOsteoblastsOsteogenesisPreservatives, PharmaceuticalRatsRats, WistarTibiaTissue PreservationTransplantation, HomologousArtigoAcesso aberto2-s2.0-0034567599016995536396809715669282198280568843503367647381
