摘要: 目的:建立兔隔离肺灌注系统,并进行阿霉素隔离肺灌注化疗的有效性和对肺组织及全身的安全性评估。方法:将16只家兔分为实验组(建立隔离单肺灌注系统,使用阿霉素进行灌注化疗)及对照组(使用阿霉素静脉化疗),分别应用荧光分光光度法检测兔血清及肺、心、肝、肾组织中阿霉素含量、计算肺湿/干重量比、HE染色后观察肺组织学改变。结果:实验组兔血清阿霉素含量为(0.055±0.125)mg•L-1,对照组的血清阿霉素含量为(1.075±0.931)mg•L-1,实验组兔血清阿霉素含量较对照组明显减少(P<0.001);与对照组比较,实验组兔左肺中阿霉素含量显著升高(P<0.001);而心、肝、肾组织中阿霉素含量明显减少(P<0.001)。实验组兔左肺(隔离灌注肺)的湿/干重量比为6.491±0.248,右肺的湿/干重量比为5.937±0.361,双肺的湿/干重量比差异无显著性(P>0.05);HE染色结果显示实验组与对照组均未见肺泡壁增厚、间质及肺泡水肿等改变。结论:隔离肺灌注化疗可在肺组织局部得到较高的化疗药物浓度,并最大限度减少全身毒性,同时保证了灌注肺的安全性,为晚期肺癌及肺转移癌提供了一种安全、有效的治疗方法。

Abstract: Abstract:Objective To establish an animal model of isolated lung perfusion(ILP) system to evaluate the effects of the ILP chemotherapy with adriamycin(ADM) and the safety to the lung and body.Methods Total 16 rabbits were divided into 2 groups.One group(experiment group) was established the ILP system and carried the perfusion chemotherapy with ADM.One group(control group) was carried the normal vein chemotherapy with ADM.Then the ADM levels in the tissues of two lungs,heart,liver and kidney were examined by fluorescence spectrophotometry.The ratio of wet to dry lung weight was detected,and the pathological changes were observed after HE staining.Results The serum ADM levels were(0.055±0.125) mg•L-1 in experiment group and (1.075±0.931) mg•L-1 in control group,the serum ADM level in experiment group was lower than that in control group(P<0.001).Compared with control group,the ADM level in the left lung increased(P<0.001),but the ADM levels in the heart,liver,kidney decreased.The ratio of wet to dry weight of the left lung in experiment group was 6.491±0.248,and 5.937±0.361 in control group,there was no significant difference(P>0.05).No alveolar wall thicken,alveolar and mesenchyma edema were found in two groups.Conclusion ILP chemotherapy can get high drug concentration in the local lung tissue.It can decrease the toxicity to the whole-body and guarantee the safe of the perfusioin lung.It provide a safe and effective therapy for the advanced lung cancer and lung metastasis cancer.
