Abstract

The aim of this work was to confirm in vitro biocompatibility of a new gel-derived glass-crystalline material containing hydroxyapatite and wollastonite phases. For the purpose of comparison, studies were also carried out for a material of the same chemical composition obtained by the traditional melting method. We examined the behaviour and response of cells cultured in the presence of the studied materials. The level of activation of macrophages in culture was determined using three different methods: measurement of respiratory burst by chemiluminescence, nitrite assay and by bioassay of secreted cytokines after immunoelectrophoresis of acute phase proteins from hepatoma cells. All our results show a relatively low, close to control level, activation of macrophages exposed to the studied materials. This indicates a good biocompatibility of both the gel-derived material and the material obtained by the traditional melting method
