苦参碱对大鼠原位肝移植冷缺血再灌注中肝窦内皮细胞损伤的影响

目的：探讨苦参碱（Mat)对大鼠原位肝移植冷缺血再灌注损伤的肝窦内皮细胞的保护作用及其机制,方法：应用大鼠原位肝移植模型,供肝保存5小时,126只大鼠随机分为对照组,Mat40mg/kg治疗组,Mat80mg/kg治疗组和假手术组,分别检测移植术后1、2、4小时血透明质酸及肝组织细胞间粘附分子－1的含量,并观察肝血窦内皮细胞形态学的改变,结果：与对照组合比较,治疗组术后各时点的透明质酸和细胞间粘附分子－1表达均显著降低,肝血窦内皮细胞形态变化也有明显改善。结论：苦参碱在大鼠原位肝移植冷却血再灌注中保护肝血窦内皮细胞免受损伤。

Effect of matrine on cold ischemia and reperfusion injury of sinusoidal endothelial cells in rat orthotopic liver transplantation

AIM: To study the mechanism and prevention of matrine (Mat) on cold ischemia/reperfusion injury of sinusoidal endothelial cells (SEC) in rat orthotopic liver transplantation (OLT). METHODS: One hundred and twenty-six syngeneic SD rats were randomly divided into four groups (n=18): untreated group, 40 mg/kg treated group, 80 mg/kg treated group, and pseudo-treated group. After 5 h of preservation in Ringer's (LR) solution, orthotopic implantation of the donor liver was performed. At 1, 2, and 4 h after reperfusion of the portal vein, 6 rats were killed in each group to collect the serum and the median lobe of liver for assay. RESULTS: The level of hylluronic acid (HA) and intercellular adhesion molecule-1 (ICAM-1) decreased significantly in both treated groups at different times post-transplantation, and their pathological changes of SEC were ameliorated, too. CONCLUSION: Matrine can prevent SEC from ischemia and reperfusion injury in rat orthotopic liver transplantation.
