Comparative study on the adhesive capabilities of sodium alginate and guar gum as bone adhesives / 中国海洋药物

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 solidification could be finished in short time,but it had lower viscosity and fit only to the non-ion calcium supply.Conclusion Sodium alginate and guar gum are considered to be the potential natural materials of the bone adhesives.

Comparative study on adhesive strength of three colloid materials and their complexes as bone adhesives / 中国海洋药物

sodium carboxymethylcellulose.Their complexes also obtained the stongest adhesive strength in their saturated water solutions,but their adhesive strength was between their component colloid materials.The complexes integrate the characteristics of the three colloid materials and would provide valuable complex materials for the study of bone adhesives.
