目的:比较不同灌注保存方式对离体猪心的保护作用。方法以36只健康雄性巴拿马小香猪为实验对象,取出供心后根据保存技术不同分为不保存组、单纯浸泡组和以50 mL灌注容量为基础并递增,间隔时间为2 h的50,100,150 mL,200 mL间断灌注组,每组各6例。心脏灌注液和保存液均为二氮嗪强化的Celsior液(含二氮嗪30μmol/L),保存温度为4℃,保存时间10 h。比较各组左心室心肌细胞凋亡指数( AI)、心肌组织ATP 含量( ATPC )、心肌含水量( MWC)和电镜心肌超微结构。结果心脏保存后,与不保存组比较,心肌细胞发生较多凋亡、心肌组织ATPC 明显降低以及出现不同程度的心肌水肿损伤等。单纯浸泡组AI最高(34.80±0.14)%,ATPC 水平最低(1.85±0.09) nmol/mg,MWC最高(82.03±0.11)%。200 mL间断灌注组AI最低(12.35±0.10)%,ATPC 水平最高(2.32±0.03) nmol/mg,MWC 最低(77.12±0.85)%;电镜心肌超微结构显示,不保存组的心肌结构最为正常,其次为150,200 mL间断灌注组。结论在长时间心脏保存中,间断灌注保存技术对心肌的保护作用优于单纯低温浸泡保存技术;间隔2 h灌注1次,每次灌注容量为200 mL的间断灌注保存技术对心肌的保护效果较好。
目的:比較不同灌註保存方式對離體豬心的保護作用。方法以36隻健康雄性巴拿馬小香豬為實驗對象,取齣供心後根據保存技術不同分為不保存組、單純浸泡組和以50 mL灌註容量為基礎併遞增,間隔時間為2 h的50,100,150 mL,200 mL間斷灌註組,每組各6例。心髒灌註液和保存液均為二氮嗪彊化的Celsior液(含二氮嗪30μmol/L),保存溫度為4℃,保存時間10 h。比較各組左心室心肌細胞凋亡指數( AI)、心肌組織ATP 含量( ATPC )、心肌含水量( MWC)和電鏡心肌超微結構。結果心髒保存後,與不保存組比較,心肌細胞髮生較多凋亡、心肌組織ATPC 明顯降低以及齣現不同程度的心肌水腫損傷等。單純浸泡組AI最高(34.80±0.14)%,ATPC 水平最低(1.85±0.09) nmol/mg,MWC最高(82.03±0.11)%。200 mL間斷灌註組AI最低(12.35±0.10)%,ATPC 水平最高(2.32±0.03) nmol/mg,MWC 最低(77.12±0.85)%;電鏡心肌超微結構顯示,不保存組的心肌結構最為正常,其次為150,200 mL間斷灌註組。結論在長時間心髒保存中,間斷灌註保存技術對心肌的保護作用優于單純低溫浸泡保存技術;間隔2 h灌註1次,每次灌註容量為200 mL的間斷灌註保存技術對心肌的保護效果較好。

Objective To compare the protective effects of different perfusion in isolated hearts of pigs . Methods The Bama miniature pigs′donor hearts were arrested with Celsior cardioplegia solution enhanced with diazoxide ( DE, 30 μmol/L) .Isolated hearts were not preservation in un-stored group and stored in the solution in stactic cold storage group or placed in a device that providing intermittent perfusion with 50, 100, 150, 200 mL solution respectively every 2 hours in intermittent perfusion group for 10 hours at 4℃(n=6 per group).After storage, left ventricle samples were frozen, extracted, then the apoptotic index of cardiomyocytes ( AI), adenosine triphosphate concentrations ( ATPC ), myocardial water content ( MWC ) and myocardial ultrastructure were analyzed.Results After long-time hypothermic storage,compared with un-stored group, there were significantly higher with AI , MWC and lower with ATP C in the stactic cold storage group and intermittent perfusion group.The stactic cold storage group shown the highest AI [(348.0 ±0 .14)%] and MWC [(82.03 ±0.11)%], but lowest ATPC level [(1.85 ±0.09)].The 200 mL intermittent perfusion group shown the lowest AI[ (12.35 ±0.10)% ]and MWC[ (77.12 ±0.85)%], but the highest ATPC level [(2.32 ±0.03) nmol/mg].The myocardial histological results were best in un-stored group and better in the intermittent perfusion which were infusion 150 or 200 mL cardioplegia solution every 2 hours. Conclusions The intermittent perfusion provide better myocardial protection than cold static storage in isolated heart preservation for 10 hours at 4 ℃.Perfusing with 200 mLsolution every 2 hours shown a more superior protective effect.
