METHODS: A limb ischemia-reperfusion injury model in rats was established. The animals were randomly divided into three groups: control group, IR group and IPC group. The contents of diamide oxidase, nitric oxide, endothelin-1 (ET-1) and ratio of nitric oxide/endothelin-1 (NO/ET-1) in the plasma and the gut were measured. The leavels of myeloperoxidase, ratio of DNA chain, total nitric oxide synthase, inducible nitric oxide synthase and constitutive nitric oxide synthase in the gut were determined.

雄性Wistar大鼠18只，随机分为对照组，缺血再灌注组和缺血预适应组，每组6只，分别测定血浆和小肠组织二氨氧化酶、一氧化氮、内皮素-1(ET-1)、NO/ET-1比值的含量变化及小肠组织的髓过氧化物酶、DNA双链百分率(ratio of DNA chain %)、总一氧化氮合酶、诱导型一氧化氮合酶、结构型一氧化氮合酶的水平；免疫组化法检测小肠组织的诱导型一氧化氮合酶、内皮型一氧化氮合酶的表达。

The damage of hepatic kupffer cells function and intestine mucosae protective screen function caused cooperatively by ischemia, hypoxia, microcirculatory disarrangement, inflammatory mediators (O〓, OH〓 etc) and cytokines (TNF-α, IL-1, IFN-γetc), the functional damage easily results in bacterial translocation and endotoxemia, as the damage mitigates the clearance of bacteria and toxin.

缺血、缺氧、微循环障碍、炎症介质及细胞因子（TNF-α、IL-1、IFN-γ等）共同作用，使肝脏Kuppfer细胞和肠粘膜屏障功能受损，对内毒素清除能力减弱致内毒素血症，是肝功能衰竭的重要病生环节，亦是继发多脏器衰竭的始动因素，但ALF致病确切机制目前尚不十分清楚。

RESULTSdiabetic rats showed typical symptoms involving elevated serum glucose and weight loss (2)The rats in DM+VaD group reacted slower and made more error numbers in Y-maze than the rats in VaD group did, with a prolonged total reacting time in a whole day.(3)More neurons with serious damages, such as edema, ischemia or pyknosis could be found in DM+VaD group than in VaD group. More disarrangement of cone neurons, obvious glia proliferation, and more neuron apoptosis were found in CA area of hippocampus. CONCLUSIONS (1)2-VO in STZ-induced diabetic rats succeeded in establishing VaD animal models.(2) The cognitive dysfunction induced by VaD rats had been deteriorated by diabetes mellitus.(3)Morphology evidences proved that diabetes mellitus aggravated brain damages induced by VaD.PART II Effect of diabetes mellitus on the cholinergic nervous systemin CA1 area of hippocampus of VaDOBJECTIVE To estimate the role of cholinergic nervous system in hippocampus during the process of cognitive dysfunction aggravated by diabetes mellitus in DM+VaD group. METHODS Observe the changes of ChAT protein by immunohistochemistry stain. Chose three rats randomly from each group at each pointat two week, four week, and eight week, then sepa
