摘要 目的:研究白细胞介素-1β、肿瘤环死因子α和白细胞介素-6在瘢痕组织中的表达,并对其意义进行探讨.方法:本文运用免疫组化法,分别应用抗白细胞介素-1β、肿瘤坏死因子α和白细胞介素-6的单克隆抗体,对20例烧伤患者肉芽和瘢痕组织中白细胞介素-1β、肿瘤坏死因子α和白细胞介素-6的表达水平进行了检测.结果:在伤后一个月的肉芽和三个月的瘢痕组织中白细胞介素-1β、肿瘤坏死因子α和白细胞介素-6有较多表达阳性的细胞,而在伤后一年的晚期瘢痕组织中,上述细胞因子表达阳性的细胞则明显减少.表达阳性的细胞主要为单核巨噬细胞、成纤维细胞和淋巴细胞.结论:免疫细胞通过直接产生或诱导产生的这些细胞因子,对成纤维细胞的增殖调控具有重要的作用。 Aim:Toinvestigatetheroleofcytokinesinthepostburncicatricialtissue.Methods:Wecolectedbiopiesfrom20casesofgranulationandscartissues.ThelevelsofTNFα,IL-1βandIL-6wereimmunohistochemicalydetectedinthesebiopsieswithanti-IL-1β,TNFαandIL-6monoclonalantibodies.Results:Therewerecytokinepositivelyex-pressingcelsinthesamplesofgranulationandscartissues.Thenumberofthesecytokinepositivelyexpressingcelsintheearlystagecicatricialtissueswasmorethanthatofthelatestageones(P<0.05).Thesestainingcelsweremainlydistributedinmacrophages,fibroblastsandlymphocytesofthegranulationandscartissues.Conclusion:TheresultssuggestthatIL-1β、TNFαandIL-6maytakeanimportantpartintheproliferationandmodulationoffibrolasts,whichhasadirectbearingonthedevelopmentofhyperplasticscars.
