The aim of this study was to prepare nonwoven materials from poly(epsilon-caprolactone) (PCL) and their antibiotic containing forms by electrospinning, so as to prevent postsurgery induced abdominal adhesions in rats. epsilon-Caprolactone was first polymerized by ring-opening polymerization, and then it was processed into matrices composed of nanofibers by electrospinning. A model antibiotic (Biteral) was embedded within a group of PCL membranes. In the rat model, defects on the abdominal walls in the peritoneum were made to induce adhesion. The plain or antibiotic embedded PCL membranes were implanted on the right side of the abdominal wall. No membrane implantation was made on the left side of the abdominal wall that served as control. Macroscopical and histological evaluations showed that using these barriers reduces the extent, type, and tenacity of adhesion. The antibiotic embedded membranes significantly eliminated postsurgery abdominal adhesions, and also improved healing.
本研究的目的是通过静电纺丝法用聚(ε-己内酯)(PCL)制备非织造材料及其含抗生素形式,以防止大鼠术后诱导的腹部粘连。首先通过开环聚合法使ε-己内酯聚合,然后通过静电纺丝将其加工成由纳米纤维组成的基质。将一种模型抗生素(Biteral)嵌入一组PCL膜中。在大鼠模型中,在腹膜的腹壁上制造缺损以诱导粘连。将普通或嵌入抗生素的PCL膜植入腹壁右侧。腹壁左侧不进行膜植入作为对照。宏观和组织学评估表明,使用这些屏障可减少粘连的程度、类型和韧性。嵌入抗生素的膜显著消除了术后腹部粘连,并且还改善了愈合情况。
