The establishment of an animal model for laryngeal allotransplantation in rat has enabled us to correlate clinical impressions of laryngeal allograft rejection with histologic data. In this study we used both clinical and histopathologic criteria to define the sequence and time parameters of rejection in histoincompatible vascularized rat laryngeal allografts.

The establishment of an animal model for laryngeal allotransplantation in rat has enabled us to correlate clinical impressions of laryngeal allograft rejection with histologic data. In this study we used both clinical and histopathologic criteria to define the sequence and time parameters of rejection in histoincompatible vascularized rat laryngeal allografts. Of the 31 rats receiving vascularized laryngeal allografts, 18 served as experimental group, in which allogeneic transplantations were performed from inbred SD to outbred Wistar rats, 13 rats used as controls receiving laryngeal histocompatible transplants. The clinical phenomena of rejection aas started at 3 days post operation, characterized by noticeable dermal swelling and lymphadenectasis of the recipient's neck. At this time, the graft appeared slightly edematous. These changes progressed and were more pronounced by 1 week. Two weeks after operation, the recipients exhibited an inflammatory scar tissue encasing the graft, the normal laryngeal architecture of grafts was invisible. Gross clinical evidence of rejection was well correlated with pathologic findings. Three days following transplantation, there was a slight histologic difference between the experimental group and the control group. Five days later, the surface respiratory epithelium exhibited progressive squamoi metaplasia, and minor salivary glands were mostly atrophic, afterwards extensive loss of acini emerged, with predominant lymphocyte and polymorphonuclear leukocyte infiltration throughout the lamina propria, sub mucosa and the laryngeal adventitia. The arteriolar walls showed fibrinoid changes, with reactive intimal proliferation,and thickening of vessel wall. Focal thrombosis were frequently found. By 2 weeks, the normal architecture of the laryngeal allografts had nearly completely been replaced by fibrovascular connective and granulation tissues. Definition of the time sequence and histopathology of rejection will allow future determination of the efficacy of various immunosupressive agents.

为探讨大鼠同种异体喉移植免疫排斥反应发生的时间和发展过程,共实施大鼠喉移植术31只。其中对照组(n=13):供、受体均为封闭群SD大鼠,属同系喉移植术。实验组(n=18):供体为封闭群SD大鼠,受体为Wistar大鼠,属同种异体移植术。免疫排斥反应开始于术后第3天,表现为受体颈部皮肤肿胀,淋巴结肿大,7天后颈部皮肤硬肿显著,移植物组织水肿,逐渐被纤维结缔组织包裹。相应的组织学变化特点是:术后第3天变化与对照组基本相同,5天后实验组粘膜上皮逐渐出现鳞状上皮化生,固有层和粘膜下层腺体发生萎缩并消失,横纹肌变性坏死,上述各层组织出现进行性淋巴细胞、单核细胞和多形核白细胞浸润,血管纤维素样变性,管壁增厚,管内血栓形成,14天后喉移植物的正常组织结构被纤维结缔组织和肉芽组织取代,最终出现完全性变性坏死。由此判断了同种异体喉移植免疫排斥反应发生的时间、顺序和程度,为免疫抑制剂的应用及功效评价提供了客观依据。

目的探讨受区炎性疤痕吻合血管游离皮瓣移植术中的血管的正确判断和处理方法,提高游离皮瓣手术的成功率。方法受区炎性疤痕,需行游离皮瓣修复7例,其中桥式交叉吻合1例,血管移植3例,扩大清创至正常区域吻合3例。结果所有皮瓣均完全存活,未出现血管危象,术后功能恢复良好。结论受区慢性感染所致的炎性疤痕内的血管不可行血管吻合,吻合处应位于正常组织内,以提高皮瓣存活率,减少术后血管危象发生。

Purpose: To investigate the clinical application and value of Multi - slice Helical CT virtual endoscopy in central airway benign diseases.Materials and Methods: Twenty - nine patients of central airway benign diseases (2 tracheal bronchus, 1 trachea diverticulum, 1 bronchus atresia, 1 esophageal trachea fistula^ bronchial tuberculosis,3 relapsing polychondritis,2 inflammatory scar,2 lancination, 1 blood clot,5 mucus blots,and 2 vessel oppression) underwent multi - slice helical CT virtual endoscopy(VE) examination (collimation 2.5mm or 5.0mm,p = 1.25 or 1.75, reconstruction interval 1.6mm or 2mm). Mucus was confirmed by follow - up CT exam and fibrobron - choscope(FOB) , the others by fibrobronchoscope (FOB) . Results: Anatomical abnormalities and mucus were all diagnosed definitely and showed clearly, the others were showed complemental information which were useful for location and narrow estimation. The coherence with FOB was very good (22/24) .Conclusion:Benign diseases can be showed sufficiently on virtual endoscopy. VE did the complemental role on the diagnoses. Anatomical abnormality and mucus could be diagnosed definitely, which could avoid FOB or repeated examination.

目的:探讨多层螺旋CT仿真内镜(virtual endoscopy,VE)在中央气道良性病变评价中的价值。材料和方法:29例中央气道良性病变,包括解剖性异常5例(气管性支气管2例、气管憩室1例、先天性支气管闭锁1例、食管气管瘘1例),炎症性病变14例(支气管内膜结核9例、复发性多软骨炎3例、慢性炎症瘢痕2例)和其他10例(外伤性气管支气管撕裂2例、支气管腔内血凝块1例、支气管腔内痰栓5例、血管压迫2例)。痰液经CT复查或纤微支气管镜证实,其余病例均经纤维支气管镜(Fibrobronchoscope,FOB)及活检证实。采用多层面CT机,准直2.5mm或5mm,p=1.25或1.75,重建间隔1.6mm或2mm,容积性VE观察。结果:解剖性异常和疾液栓VE明确诊断(12/12),显示详细;其他气道良性疾病能一定程度上显示补充信息,对有辅助定位及判断良性狭窄的程度或范围有一定的诊断价值。与FOB有较好的一致性(22/24)。结论:VE能充分显示良性病变,对横断面起很好的补充说明作用。解剖性异常和多数痰液栓能明确诊断,可免除FOB或重复检查。
