ABSTRACT
Objective:
To explore the expression of TNF a and IL-10 in different layers of laryngeal tissues after laryngeal transplantation and its relationship with acute rejection.Methods:
Laryngeal heterotopic transplantation was performed in Wistar and SD rats(Wistar→SD rats).The SD rats were divided into 4 groupsGroupⅠSham control(receive no transplantation) GroupⅡ(receive transplantation,without cyelosporine A treatment);GroupⅢ(receive transplantation.with 5 mg?kg~(-1)?d cyelosporine A treatment)and GroupⅣ(receive transplantation.with 10 mg?kg~(-1)?d~(-1)cyelosporine A treatment).The transplanted larynx was harvested on 3,7 and 11 days after transplantation for pathological examination.The expression of TNF-?and IL-10 in different layers of grafts was detected immunohistochemically.Results:
Pathological observation showed mild,moderate and severe acute rejection in GroupⅡandⅢon 3.7 and 11 days after transplantation,respectivelythere was no obvious rejection in GroupⅣ.Immunohistochemical staining showed expression of TNF-?and IL-10 in GroupⅡ.Ⅲ.andⅣ,not in GroupⅠ.The ratios of the positive areas of TNF-?and IL-10 in the mucosal and submucosal layers were significantly higher than those in the muscle and cartilage layers of laryngeal tissues(P
