title: Study of in vivo biocompatibility and dynamics of replacement of rat shin defect with porous granulated bioceramic materials.
abstract: Biocompatibility of porous granulated bioceramic materials (hydroxyapatite, beta-tricalcium phosphate, hydroxyapatite-b-tricalcium phosphate complex (80:20 wt%), carbonate-containing hydroxyapatite, and silicon-containing hydroxyapatite) was shown in a subcutaneous test on BDF1 mice. Dynamic (up to 8 months) observation showed gradual replacement of the granular substance with de novo forming bone tissue with hemopoiesis foci on a model of fenestral defect in the shin bone in Wistar rats. By the rate of resorption, the materials rank as follows: silicon-containing hydroxyapatite<hydroxyapatite<hydroxyapatite-beta-tricalcium phosphate<beta-tricalcium phosphate<carbonate-containing hydroxyapatite. The rate of resorption in bone tissue defect was significantly higher than in the subcutaneous test, but lagged behind (even for tricalcium phosphate and carbonate-containing hydroxyapatite) bone tissue formation de novo.
