目的 :比较经过保存的异种 (猪 )巩膜与同种异体 (兔 )巩膜及人工合成材料作为埋藏材料的术后效果 ,为眼科手术探寻新的应用材料。方法 :在白兔背部及眼睑皮下分别植入甘油保存的猪巩膜、甘油保存的兔巩膜、酒精保存的猪巩膜、医用硅橡胶片。术后 1、4、12周取出 ,进行大体观察和组织学检查 ,部分植片还进行电镜检查。结果 :同种异体巩膜和异种巩膜植片在受体内的转归相似。结论 :保存猪巩膜有希望成为人同种异体巩膜的代用品。
OBJECTIVE: To compare the postoperative effects of preserved sclera and allogeneic rabbit (sclera) sclera and synthetic materials as burial materials, and explore new application materials for ophthalmic surgery. Methods: Rabbit sclera preserved in glycerol, pig sclera preserved in glycerol, porcine sclera preserved in alcohol and medical silicone rubber sheet were implanted subcutaneously in the back of rabbit and eyelid respectively. At 1, 4, 12 weeks after operation, the patients were taken out for general observation and histological examination. Some of the implants were also examined by electron microscopy. RESULTS: Allo-sclera and xeno-scleral implant resection in recipients were similar. CONCLUSIONS: The preservation of the sclera of pigs is promising as an alternative to human sclera.
