Seven different suture materials were implanted into the oral tissues of 12 cats. The sutures and surrounding tissues were retrieved en bloc from each of two cats on days one, three, seven, 14, 21, and 28 postimplantation. Tissue reaction and suture duration were evaluated by gross visual observation and histological examination. Chromic gut disappeared between days three and seven; polyglactin 910 disappeared between days 14 and 21; and polyglycolic acid disappeared as early as seven to 14 days. Polydioxanone still was intact at day 28 and is recommended as an absorbable material for procedures in which longer healing time is anticipated. All the nonabsorbable suture materials (i.e., polypropylene, stainless steel, and nylon) were intact at day 28 postimplantation. Visual inspection showed polypropylene to have the least tissue reaction.
将七种不同的缝合材料植入12只猫的口腔组织。在植入后的第1、3、7、14、21和28天，从两只猫中各取出一组缝合线及其周围组织。通过大体观察和组织学检查评估组织反应和缝合线存留时间。铬制肠线在第3至7天之间消失；聚乙醇酸910在第14至21天之间消失；聚乙醇酸早在第7至14天就消失了。聚二氧六环酮在第28天仍保持完整，推荐作为预期愈合时间较长的手术中使用的可吸收材料。所有不可吸收缝合材料（即聚丙烯、不锈钢和尼龙）在植入后第28天均保持完整。肉眼检查显示聚丙烯的组织反应最小。
