Comparative study on the adhesive capabilities of sodium alginate and guar gum as bone adhesives

摘要

目的比较研究海藻酸钠和瓜儿胶作为骨骼黏合材料的黏合性能。方法通过测定两种胶体的动力黏度、固化时间和对钙离子的作用,探讨相应的黏合性能。结果瓜儿胶的黏度较高,能适应多种形式的补钙剂,但其固化性能还有待改进;海藻酸钠固化性能优越,能在瞬间完成固化,但其黏度比瓜儿胶低,只能适应非离子钙型的补钙剂。结论海藻酸钠和瓜儿胶都是较有潜力的天然骨骼黏合剂。 【英文摘要】 Objective To comparatively investigate the adhesive capabilities of sodium alginate and guar gum as bone adhesives.Methods The adhesive capabilities were analysed and discussed by measuring their kinetic viscosities,solidification time and the reaction with calcium ions.Results Guar gum had higher kinetic viscosity and could fit to the supply of both ion calcium and non-ion calcium for the bone cure,but its capability of solidification need to be improved.Sodium alginate had higher solubility and its solidi...
