摘要：

This study describes the potentiality of crosslinked hydrogels comprised of gelatin and polyacrylic acid (CHGP) as a biological glue for soft tissues and compares its bonding strength with that of fibrin glue. Water-soluble carbodimide (WSC) was used to crosslink the mixture of gelatin and polyacrylic acid (PAA). An addition of PAA to gelatin increases bonding strength and reduces the gelation time and WSC concentration. Increasing the gelatin, WSC and PAA concentration increases the bonding strength. There is a critical concentration to have a maximum bonding strength. The cured hydrogel exhibited sufficient adhesion to mouse skin with a higher bonding strength than fibrin glue. The in vitro test has been done for evaluating CHGP toxicity.
