Resumo
Foram empregados 30 ratos, machos, linhagem Wistar. Implantou-se sob a pele segmentos de 3cm de comprimento de linha de pescamantida em formalina, linha de pescaautoclavada uma vez, linha de pescaautoclavada duas vezes e fio de náilon cirúrgico. Cada animal recebeu dois tipos de material de sutura, em locais paralelos e eqüidistantes da coluna vertebral. Foram sacrificados com cinco, 15 e 90 dias de pós-operatório para que se procedesse o exame histopatológico. Pelo grau de reação tecidual pode-se concluir que: a maior reação ocorreu com a linha de pesca mantida em formalina e a menor com o fio de náilon cirúrgico; as linhas de pescaautoclavadas uma e duas vezes se comportaram de forma semelhante e apresentaram um reação intermediária.
Thirty male Wistar rats were implanted under the skin with surgical nylon or fishing line maintained in formalin or fishing line autoclaved once or twice. Two different types of 3cm length suture material were implanted in each animal parallel and equidistant sites from the vertebral column. The animals were sacrificed at five, 15 and 90 days postoperative for histopathological examination. The greatest tissue reaction was observed in those animals implanted with fishing line maintained in formalin and the smallest reaction in those implanted with surgical nylon. Animals implanted with once and twice autoclaved fishing line showed similar and intermediary reaction.
