目的:观察胰岛素对大鼠肠缺血再灌注后小肠组织损伤的影响。方法:雄性SD大鼠40只随机分为4组,每组10只,手术对
照组、单纯缺血组、再灌注组、胰岛素干预组。于30min 缺血和120min 再灌注后,进行组织病理学和生化检测。结果:(1)单纯缺血
组肠粘膜损害较手术对照组明显升高(P<0.01),超氧化物歧化酶(SOD)活性无明显变化;(2)再灌注组SOD 活性明显降低,与手
术对照组和单纯缺血组相比较差异均有显著性(P<0.01);(3)胰岛素组SOD 活性与再灌注组相比有明显改善(P<0.01)。结论:
肠缺血可以引起肠粘膜损伤,再灌注则可加重这种损伤,胰岛素可以减轻再灌注损伤。 |

Objective: To investigate the effects of insulin on gut injury following intestinal ischemia-reperfusion (I/R). Methods:
Forty male SD rats were randomly divided into 4 groups ,n=10 in each group: (1)control group,(2)simple ischemia group,(3)re-perfusion
group, (4)insulin group. Results: (1) Mucosal injury score were significantly higher in the simple ischemia group than the control group
(P<0.01), the SOD activities have no evident change;(2)The SOD activities of the re-perfusion group were significantly decreased compared
to the control group and simple ischemia group(P<0.01);(3)The SOD activities in the insulin group were significantly higher
compared to the reperfusion group(P<0.01). Conclusion: Intestinal ischemia can damage the intestinal mucosa in rats. Reperfusion can
lead to further injury.Insulin can attenuate the mucosa damage. |
