Abstract:
ObjectiveTo investigate the establishment of stable mice orthotopic left lung transplant model MethodsForty male Balb/c mice randomly served as recipients and donors.Each couple had the similar weight. Three-cuff technique was used to establish mice orthotopic lung transplant model.The micro CT of chest and the artery blood analysis were detected at first month after transplantation.ResultsThe achievement ratio was 95％.More than 90％ of the recipients survived after surgery.Cold ischemia time was (35.6±5.9) min,warm ischemia time was (25.3±7.2) min,donor lung back up time was (21.0±5.6) min,and the whole surgery time was (85±15)min.The long-term survival time achieved more than 30 days with functional lung graft.Micro CT showed clear left lung graft field one month after surgery,and left bronchus cuff was still open.The PaO2 of the artery blood was ( 106.9±5.8 ) mmHg before clipping right lung hlium,and after clipping that was (105.0±8.7) mmHg with the difference being not significant between them (P＞0.05).Histologically,the lung graft appeared very similar to the right lung one month after surgery.The pulmonary alveoli were aerated well.ConclusionBased on our experience of the orthotopic lung transplantation model in mice,through practicing,we independently and successfully established orthotopic lung transplantation model in mice.Compared to the method established by the other country,our method is easier to perform and more stable.This will benefit the basic research related to lung transplantation.
