✦ Synopsis

Nylon monofilament sutures were tested in a straight pull as well as a conventional knot pull tensile test. In each test, sutures were evaluated following storage under prevailing atmospheric conditions or saturation in whole human blood. Blood saturation decreased the ultimate tensile strength by as much as 20%. The present investigation of sutures that were stored under prevailing atmospheric conditions substantiated the proposal previously made for polypropylene monofilaments-that 60% of the ultimate tensile strength could be established as a fundamental USP criterion for Class I monofilament sutures. *No benefit of any kind will be received either directly or indirectly by the authors. "The criterion would be 0.60 x 1.25 or or 0.75 a, for either unsterilized sutures or sutures sterilized by nonradiation methods (cf. Table I1 of Ref. 2).

It is well known that compression speed can have significant effects on the compaction properties of pharmaceutical powders. This is a challenge during scale up and technology transfer when tableting speeds are significantly increased. This study examined the effects of tableting speed on the compre

## Background and objective: Laser-assisted tissue repair is often accompanied by a high dehiscence rate, which may be due to alterations in suture material after laser exposure. the goal of this study was to investigate the effect of co2 laser irradiation on the tensile strength of microsurgical s
