摘　　要：由化学分析和扫描电镜观察结果表明:经较大剂量^(60)Coγ线照射后,猫皮皮片胶原耐热碱和胶原酶水解能力明显下降,但皮片经0.01％—0.10％戊二醛预处理能提高其耐辐照能力。照射-冻干组皮片明显优于相应的冻干-照射组皮片。The results of chemical analysis and scanning electron microscopicobservation show that large dose of ^(60)Co gamma radiation decreases substantially thechemical and biological stability of porcie dermal collagen after hydrolysis withhot alkali. and collagenase, But pretreatment with 0.01%--0.1% glutaraldehyde isbeneficial for the improvement of its stablity; radiation in the wet state is betterthan in dry.
