目的觀察普伐他汀(pravastatin)對異種胰島移植物存活的影響。方法將豬→小鼠胰島移植模型分成A組(對照組)、B組(CsA組)、C組(普伐他汀組)、D組(CsA+普伐他汀組)。觀察指標(biāo): 移植物存活時(shí)間、病理檢查、免疫組化染色、血清NO含量及移植物IFNγ mRNA的表達(dá)。結(jié)果A、B、C和D組移植物平均存活時(shí)間分別為(6.2±0.82) d、(9.2±1.92) d、(7.2±1.30) d及(11.2±1.76) d,D組存活時(shí)間明顯長于其它3組(P<0.05); D組移植物浸潤細(xì)胞較其它3組少。術(shù)后第4天,血清NO水平A組為(105.8±19.3) mmol/L,明顯高于B組的(88.2±21.4) mmol/L(P<0.05)、C組的(70.7±17.8) mmol/L(P<0.01)及D組的(56.3±16.4) mmol/L(P<0.01),出現(xiàn)移植排斥時(shí),C、D組的血清NO水平分別為(83.7±10.6) mmol/L及(71.3±13.8) mmol/L,仍較A組低(P<0.05),B組為(104.7±16.3)mmol/L,與A組比較差異無顯著性意義(P gt;0.05)。術(shù)后第4天血清IFNγ mRNA表達(dá),D組為23.5±4.6,較A組的28.8±4.8低(P<0.05),而B、C組與A組間差異無顯著性意義(P gt;0.05)。結(jié)論普伐他汀能抑制巨噬細(xì)胞活性,延長異種胰島移植物存活,尤其與CsA聯(lián)用效果更好。
