regeneruojant celiulozę iš celiuliozės diacetano acetono tirpale, gautas celiuliozės gelis. Liofilizavus gelį gautas porėtas celiuliozės karkasas. Nustatyta, kad sintetiniame kūno skystyje ant atitinkamai modifikuotos celiuliozės formuojasi hidroksiapatitas.
Itroduction. Cellulose is an abundant renewable, biocompatible, non-toxic and biodegradable polymer. It has wide range of applications in variuos areas such as the textile, food paper, pharmaceutical industry and the biomedical field as tissue engineering material. Despite the good mechanical properties the potential of cellulose for bone replacement is limited because that it does not bond directly to bone under physiological conditions. The aim of this work was to investigate method for covering porous cellulose matrix with a bioactive hydroxyapatite layer. [...].
