To establish a murine carotid artery transplantation model for the study of the chronic rejection, 80 rats were divided into two groups, an allotransplant (ACI-Lewis) group and an isotransplant (Lewis-Lewis) group (control group). The donor carotid artery and the recipient carotid artery were anastomosed by using a polyethylene cuff (internal diameter: 0.7 mm, length: 3 mm).The pathological changes of carotid artery transplant were observed 14, 28 and 56 days after the transplantation. The results showed that the model was successfully established in 95% of the animals. The chronic rejection-associated arteriosclerosis was induced 28 days after the transplantation. The new chronic rejection model of carotid artery by using cuff technique caused fewer traumas and was easy to make. The pathological changes of the transplant mimicked the chronic rejection-associated arteriosclerosis found in human transplant. 相似文献

目的探讨分次切除在皮肤病损治疗中的应用价值。方法通过10年来对498例皮肤病损患者接受分次切除治疗的观察和分析,评估了皮肤病损分次切除的疾病适应证、部位适应证、切口的合理安排和优缺点等。结果所有病例中切除次数为2次的病例457例,治疗时间5~13月,平均(8.06±3.45)月;3次及以上41例,平均(3.12±0.32)次,治疗时间12~21月,平均(13.76±1.34)月。术后随访6~13月,复发5例,其中色素痣3例,疤痕疙瘩2例。色素痣再次手术切除后无复发,疤痕疙瘩采取切除加放疗后无复发。结论分次切除在较大面积及特殊部位的皮肤病灶切除术中有其特有的优点和临床应用价值。 相似文献
