[Background] The purpose of this study was to clarify the effect of GGA to prevent the ischemia-reperfusion injury in the small intestine. [Methods] 1, Male Wistar rats were divided into two groups. Control group(n=4), was administered a vehicle 4 hour before ischemic condition. GGA group(n=4) was administered GGA (100mg/kg) 4 hour before ischemic condition. Ischemia- reperfusion injury in the small intestine was induced by 40 minute clamping of the root of superior mesenteric artery. After 60 minute reperfusion, cytokines in the blood were measured by RT-PCR. And the extent of damage of the mucosa was evaluated by immunohistochemical stain of HSP70.[Results] IL-1 was significantly lower in GGA group than control group (GGA vs cont : 1.78±0.90 vs 0.92±0.21, p<0.05).IL-6 was significantly lower in GGA group than control group (GGA vs cont : 78.5±40.0 vs 8.6±5.1, p<0.05). INF-_Y, Caspase 3 and TNT-α showed no significant changes. Egr- 1 was significantly lower in GGA group than control group(GGA vs cont 2.02±1.20 vs 0.44±0.28, p<0.05). HSP70 was overexpressed in the GGA group. [ Conclusion] HSP induced by GGA suppressed expressions of Egr-1 and inflammatory cytokines,produced by ischemia-reperfusion injury of small intestine.

[背景]本研究旨在探讨甘草酸对小肠缺血再灌注损伤的保护作用。[方法] 1、雄性Wistar大鼠随机分为两组。对照组（n=4）在缺血条件前4小时给予媒介物。GGA组（n=4）于缺血前4 h给予GGA（100 mg/kg）。夹闭上级肠系膜动脉根部40分钟造成小肠缺血再灌注损伤。再灌注60分钟后，用RT-PCR法检测血中细胞因子的含量。用免疫组化方法检测HSP 70的表达。[结果] GGA组IL-1明显低于对照组（GGA vs cont：1.78±0.90 vs 0.92±0.21，p<0.05）; GGA组IL-6明显低于对照组（GGA vs cont：78.5±40.0 vs 8.6±5.1，p<0.05）。INF-Y、Caspase 3和TNT-α无明显变化。GGA组Egr- 1明显低于对照组（GGA组为2.02±1.20，对照组为0.44±0.28，P<0.05）。GGA组HSP 70高表达。[结论] GGA诱导的HSP可抑制小肠缺血再灌注损伤后Egr-1和炎性细胞因子的表达。
