Abstract
Plain and chromic catgut, Dexon, and Vicryl were exposed to the acid-pepsin secretions of the stomach in vivo in dogs. No plain gut was recovered in 24 hours; chromic was found as long as 48 hours after implantation but the breaking strength was reduced markedly. Dexon and Vicryl lost strength slowly in a curve similar to the loss after implantation in other tissues.
摘要
将普通肠线、铬制肠线、聚乙醇酸缝线和聚乳酸羟基乙酸缝线置于犬体内，使其暴露于胃的酸性胃蛋白酶分泌液中。24小时后未发现普通肠线；铬制肠线在植入后48小时仍可找到，但抗张强度明显降低。聚乙醇酸缝线和聚乳酸羟基乙酸缝线强度缓慢下降，其曲线与植入其他组织后的强度下降曲线相似。
