  Objectives: Demineralized bone matrix(DBM)is mainly composed of collagen and bone morphogenetic proteins(BMPs).Collagen is a good scaffold for the migration,adhesion of dental pulp cells and the deposition of dentine,BMPs has been reported to induce dental pulp stem cells(DSPCs)to differentiate into odontoblast-like cells.The two main components are favorable for the formation of dentin,which suggests the possibility of its application as a pulp capping material.In this study,we established an experimental model of pulpotomy in rats and observed the histological changes of pulp tissue,the formation of reparative dentin and the expression of related factors: runt transcription factor 2(Runx2),type I collagen(COLI),osteocalcin(OCN)and dentin sialoprotein(DSP),to investigate the feasibility of its application as a pulp capping material.

近年来,新型药物传递系统迅速发展,壳聚糖以其自身的特点,如生物相容性、生物可降解性、多种生物活性成为了广泛应用的辅料。壳聚糖及其衍生物的纳米粒可以作为药物、基因运输和释放的载体,达到缓释、控释、靶向释放药物的目的。本文以壳聚糖为材料,制备乳糖化油酰壳聚糖(Lac-OCH),并对其理化性质进行了研究。首先对壳聚糖进行化学修饰,即壳聚糖与油酰氯的酰化反应制得油酰壳聚糖(OCH),修饰的目的是在壳聚糖分
