It has been proved that a layer of smooth.fibrous tissue can form over the surface of the silicon rubber tissue implanted in the experimental animals.The author concludes that this layer of fibrous tissue is helpful in preventing the abdominal organs from forming adhesions and in repairing the defects of some organs.It may also serve as a support for the growth of new tissues.Clinically,silicon rubber tissue has been successfully used in 48 operations upon child patients,including appendectomies,repairs of bony defects in meningoceles and myotomy for torticollis.%@@ 医学领域内使用的合成高聚物,称为医用高聚物.目前,合成高分子材料用于机体内公认的必需具备的条件有:(1)在化学方面呈惰性,不因机体组织及组织液的影响而变性;(2)在机体内不发生炎症和异物反应,不引起过敏反应;(3)长期放置机体内不丧失强度、弹性和机械度,无膨胀性;(4)与血液接触时不形成血栓;(5)无致癌性;(6)可以耐受常用的消毒方式如煮沸、高压消毒、药液浸泡等方法灭菌;(7)易加工和造型.除此之外,根据使用于不同的器官和部位,还要考虑一些特殊的条件.
