羊肠线的研究 (三)含铬量与消化时间的关系
STUDIES ON ABSORBABLE SURGICAL SUTURES(CATGUT)(Ⅲ)ON THE RELATION BETWEEN CHROMIUM CONTENT AND THE TIME REQUIRED FOR DIGESTION IN ACID PEPSIN SOLUTION
-
摘要: 文中介绍了试验羊肠线在酵素里消化时间的方法和含铬量的化学测定法。实验指出,因鞣制方法的不同,铬鞣羊肠线的含铬量和它在酵素里消化时间的关系,很不一致。但是若用同一方法鞣制,含铬量和消化时间是有一定关系的。所以羊肠线制造者可以采用化学定铬含量的方法来作为掌握制造过程和制品性能的一种依据。Abstract: Methods for the determination of chromium content in surgical catgut and its digestion time in pepsin are described. It is shown that with the same process of chromicization the chromium con- tent of surgical catgut has a definite relationship with the time required for its digestion in acid pepsin solution.
