摘要 目的:观察哮喘豚鼠外周血、肺和骨髓组织嗜酸性粒细胞(EOS)百分比和肺组织Eotaxin和CCR3的表达及激素对其影响。方法:健康雄性豚鼠40只,以卵白蛋白(OVA)致敏和激发制作哮喘模型,随机分为正常组(A组)、哮喘组(B组)、地塞米松干预组(C组)、布地奈德干预组(D组),每组10只,在末次激发6h后处死豚鼠;取豚鼠颈动脉血、骨髓和肺组织,分别制备血涂片、骨髓涂片和肺组织切片;外周血和骨髓涂片用Wright染色,光学显微镜下计数细胞总数和EOS百分比;肺组织切片HE染色,光学显微镜下计数细胞总数和EOS百分比;肺组织切片用Eotaxin和CCR3多克隆抗体免疫组化染色,光学显微镜下分别计数阳性细胞百分比;用Westernblot法测定肺组织中Eotaxin蛋白表达变化。结果:豚鼠外周血、骨髓和肺组织中EOS百分比,A组为(1.33±0.52)%、(1.17±0.41)%、(1.67±0.52)%;B组为(4.83±0.98)%、(3.17±0.75)%、(4.00±0.89)%;C组为(2.68±1.03)%、(1.67±0.82)%、(2.83±0.75)%;D组为(2.67±0.52)%、(1.83±0.75)%、(2.67±0.52)%;B组与A、C、D组比较差异有统计学意义(P<0.05),A组与C、D组比较差异有统计学意义(P<0.05),C组与D组比较差异无统计学意义(P>0.05),但C组较D组降低骨髓EOS百分比似乎更明显;豚鼠肺组织Eotaxin和CCR3多克隆抗体免疫组化染色阳性细胞百分比,A组为(2.29±0.35)%、(2.07±0.15)%;B组为(3.27±0.42)%、(3.66±0.47)%;C组为(2.80±0.22)%、(2.98±0.45)%;D组为(2.75±0.31)%、(2.65±0.25)%;B组与A、C、D组比较差异有统计学意义(P<0.05),A组与C、D组比较差异有统计学意义(P<0.05),C组与D组比较差异无统计学意义;免疫印迹法检测发现豚鼠肺组织Eotaxin在A、B、C、D组表达量分别为0.447±0.026、0.836±0.012、0.639±0.034、0.668±0.023,B组表达较A、C和D组明显升高(P<0.01),C组与D组比较差异无统计学意义,但仍高于A组(P<0.05);相关性分析结果提示哮喘豚鼠肺组织中EOS百分比和Eotaxin和CCR3在肺组织的表达皆呈正相关(r=0.852,P<0.001)、(r=0.671,P<0.001)。结论:哮喘豚鼠外周血、骨髓和肺组织EOS均明显增加,并与肺内Eotaxin和CCR3的表达相一致,激素可通过抑制Eotaxin和CCR3的表达和活性,有效发挥抗EOS炎症作用,是激素控制哮喘发病的重要机制。
