Autogenous transplantation of rib cartilage, preserved in glycerol, to the malar process of rats: A histological study.

Allogeneic Transplants of Rib Cartilage Preserved in 98% Glycerol or 70% Alcohol into the Malar Process of Rats: A Comparative Histological Study.

“…It is also possible that after the grafts have been reduced by resorption to a certain size, the preservation method no longer influences the process. Apart from these considerations , graft resorption occurred in a manner similar to that described in the literature [6,17,[22][23][24][25] Thus, the present study showed no advantages of one method over the other, since the grafts were well tolerated in both cases and the resorption rates were the same after 60 days. However, larger grafts or other tissue grafts may behave differently.…”

“…Preservation of cartilage in 98% glycerol [6] and 70% alcohol [7,8] planted into the malar process of rats showed comparable inflammatory reactions. The preserved material underwent faster substitution by bone].…”

“…SCARSO FILHO et al [16] observed resorption of the extremities of glycerol-preserved cartilage grafts after 7 days. If the perichondrium is maintained, it will protect the transplanted cartilage from resorption , even if devitalized by preservation in glycerol [6]. Fresh allogeneic cartilage, transplanted into the same host bed, initiates its resorption process earlier [21].…”

“…Implantes de materiais biológicos têm sido utilizados com finalidade de constituir molde ou arcabouço para o desenvolvimento de tecidos próprios do receptor, que poderão permanecer no leito receptor durante tempo indefinido. 19 Neste experimento, notou-se que o processo inflamatório ocorrido na intimidade do enxerto se caracterizou pela formação de tecido de granulação, presença de fibroblastos, grande quantidade de vasos sanguíneos e fibras colágenas neoformadas, ou seja, intensa atividade de fibroplasia (Figura 5). A força de tensão na maioria dos tecidos normais é diretamente proporcional ao conteúdo de colágeno.…”

Autogenous transplantation of rib cartilage preserved in glycerol, after removal of the perichondrium, to the malar process of rats. A histological study. (Part I).

“…Autogenous cartilage preserved in glycerol shows more intense new bone formation than fresh tissue, with comparable degrees of inflammatory reaction [20]. The present study was designed to verify whether bone neoformation and graft substitution could be further enhanced by transplantation of autogenous cartilage preserved in glycerol after removal of the perichondrium.…”
