目的  研究血管內(nèi)皮生長因子（VEGF）、誘導(dǎo)型一氧化氮合酶（iNOS）及內(nèi)皮型一氧化氮合酶（eNOS）在人胃癌表達(dá)的相關(guān)性及與胃癌血管生成的關(guān)系，探討NO和VEGF的相互作用及NO在VEGF促腫瘤生長中的作用機(jī)理。
方法  應(yīng)用免疫組化方法檢測34例胃癌組織中VEGF、iNOS和eNOS的表達(dá)及分布，用血管內(nèi)皮細(xì)胞第Ⅷ相關(guān)抗原（FⅧRAg）行免疫特異性染色計數(shù)腫瘤微血管密度（MVD）。
結(jié)果  34例胃癌組織中，表達(dá)iNOS者占73.5%，表達(dá)eNOS者占82.4%，表達(dá)VEGF者占91.2%； VEGF與iNOS的表達(dá)具有相關(guān)性（P lt;0.005），VEGF與eNOS的表達(dá)則無相關(guān)性（P gt;0.05）； 表達(dá)VEGF的胃癌其MVD明顯高于不表達(dá)VEGF的胃癌（P lt;0.025），表達(dá)iNOS的胃癌其MVD明顯高于不表達(dá)iNOS的胃癌（P lt;0.05），表達(dá)eNOS的胃癌MVD與不表達(dá)eNOS的胃癌差異無顯著性意義（P gt;0.05）。
結(jié)論  胃癌組織中MVD隨著VEGF和iNOS表達(dá)的增加而增加，提示兩者對胃癌的血管生成起促進(jìn)作用； VEGF與iNOS的表達(dá)具有相關(guān)性，提示iNOS在VEGF的生成和發(fā)揮作用過程中起重要作用。
