Protective Effects of Ulinastatin on Rabbit Lung Transplantation / 中国医师杂志

ABSTRACT

Objective To explore the protective effects of Ulinastatin on lung transplantation. Methods Orthotopic pulmonary autograft transplantation models of 24 New Zealand rabbits were established and randomly divided into four groups groupⅠ (control group,n=6), groupⅡ(given 6000U/kg UTI 30min before ischemia, n=6), groupⅢ(given 12000U/kg UTI 30min before ischemia, n=6), groupⅣ(given 12000U/kg UTI respectively 30min before ischemia and during reperfusion, n=6). Then blood samples were taken from left and right atrium respectively before ischemia, and 30min after reperfusion for white blood cells counting. lung tissue DMA content was measured and lung biopsy were performed respectively before ischemia and 2h after reperfusion. Results Compared with groupⅠ, in groups Ⅱ,Ⅲ and Ⅳ, the white cell ratio of right atrium/left atrium was significantly lower, the ratio of wet/dry lung tissue weight and lung tissue DMA content were lower, and the pathological lesion was less. Conclusion Ulinastatin has protective effects on rabbit lung transplantation.
