BACKGROUND Lung transplantation is a well-established treatment of end-stage lung disease.A rodent model is an inexpensive way to collect biological data from a living model after lung ***,mastering the surgical technique takes time owing to the small organ *** To conduct rat lung transplantation using a shunt cannula(SC)or modified cannula(MC)and assess their *** Rat lung transplantation was performed in 11 animals in the SC group and 12 in the MC *** devised a method of rat lung transplantation using a coronary SC for coronary artery bypass surgery as an anastomosis of pulmonary arteri-ovenous vessels and *** same surgeon performed all surgical proce-dures in the donor and recipient rats without using a magnifying *** success rate of lung transplantation,operating time,and PaO2 values were com-pared after 2-h reperfusion after *** Ten and 12 lungs were successfully transplanted in the SC and MC groups,*** the SC group,one animal had cardiac arrest within 1 h after reperfusion owing to bleeding during pulmonary vein *** opera-ting time for the removal of the heart-lung block from the donor and preparation of the left lung graft was 26.8±2.3 and 25.7±1.3 min in the SC and MC groups,respectively(P=0.21).The time required for left lung transplantation in the recipients was 37.5±2.8 min and 35.9±1.4 min in the SC and MC groups,respectively(P=0.12).PaO2 values at 2 h after reperfusion were 456.2±25.5 and INTRODUCTION Lung transplantation is a well-established treatment of end-stage lung *** immune and non-immune mech-anisms in lung transplantation are highly complex,and post-transplant complications such as infections and primary and chronic lung allograft dysfunction must be reduced to improve ***,there is a need for immunological and pathophysiological analyses using animal lung transplantation *** rat lung transplantation model was f
