摘要: [摘要] 目的 探讨细胞间黏附分子 1 ( intercellularadhesionmolecule-1 , ICAM-1 )高表达与大鼠重症急性胰腺
炎(
severeacutepancreatitis , SAP )早期急性肺损伤的关系。方法 40 只健康成年雄性 SD 大鼠,依据随机数字表法
分为研究组(
n =30 )和对照组( n =10 ) 2 组。将 0.1mL / 100g4% 牛黄胆酸钠匀速注入研究组大鼠胆胰管中,将等
量生理盐水匀速注入对照组大鼠胆胰管中,然后对 2 组大鼠的血淀粉酶及血气变化、肺含水率、髓过氧化物酶
( myeloperoxidase , MPO )活性、肺组织学评分及胰腺组织学评分、肺 ICAM-1 表达进行统计分析。结果 研究组大
鼠术后 3 、 6 、 12h 不同时点血淀粉酶和动脉血二氧化碳分压(
partialpressureofcarbondioxideinarterialblood ,
PaCO 2 )水平、肺含水率、 MPO 活性、肺组织学评分和胰腺组织学评分、肺 ICAM-1 积分光密度值和面积均逐渐升
高( P <0.05 );氧合指数和 PaO
2 水平均逐渐降低( P <0.05 )。研究组大鼠术后 12h 血淀粉酶和 PaCO 2 水平、肺含
水率、 MPO 活性、肺组织学评分和胰腺组织学评分、肺 ICAM-1 的面积均显著高于对照组(
P <0.01 );氧合指数、
PaO 2 水平及肺 ICAM-1 的积分光密度值均显著低于对照组( P <0.01 )。结论 ICAM-1 高表达极易引发大鼠 SAP
早期急性肺损伤。
