The effect of the absorbable material to the artery was evaluated using femoral artery of the rabbit. We make three groups of these arterial samples ; first group is control study (only the vessel isolation). Second group was one-sutured by the absorbable material (polydioxaon ; PDS), third group was one-sutured by the nonabsorbable material (nylon). Each groups we extract the artery 2,4,6,8,12 weeks after work, and observe the sample. In histological examinations, prolonged inflammatory reaction around the stitch was observed in the nonabsorbable suture group, but excellent healing without healing any inflammatory reaction was a constant finding in the absorbable group.

以家兔股动脉为实验材料，评价可吸收材料对动脉的影响。我们将这些动脉样本分成三组，第一组是对照研究（仅分离血管）。第二组用可吸收材料（聚二氧六环; PDS）一次缝合，第三组用不可吸收材料（尼龙）一次缝合。各组分别于术后2、4、6、8、12周取材，观察标本。在组织学检查中，在不可吸收缝线组中观察到缝线周围的炎症反应延长，但在可吸收缝线组中观察到愈合良好且无任何炎症反应。
