摘要
作者应用组织化学、免疫组织化学染色及自动图象分析仪观测59例急性白血病(AL)患者118次骨髓活检标本骨髓细胞外基质(ECM)成分变化及其与造血细胞增殖的关系。其中男性38例,女性21例,中位数年龄34岁。急性非淋巴细胞白血病(ANLL)41例,急性淋巴细胞白血病(ALL)18例,初诊未治者(PL)27例,难治复发者(RL)32例,正常对照10例。结果显示,AL与正常人骨髓ECM成分有显著性差异(P<0.05);AL网硬蛋白增加,纤维连接蛋白(Fn)、酸性粘多糖减低,中性粘多糖初诊未治者增高,难治复发者减低。ALL和ANLL之间未见显著性差异;RL中难以缓解与复发再治者比较,后者改变更明显,而同复发次数无显著性差异。PL中追踪观察,6/8例(75%)未缓解患者及8/19例(42.1%)完全缓解后复发患者骨髓基质Fn、酸性粘多糖、中性粘多糖有不同程度改变。骨髓基质Fn与造血细胞增殖在正常对照组显示呈正相关,而在AL呈负相关,PL与RL尚存在显著性差异(P<0.05)。提示AL骨髓造血微环境ECM有明显变化,与发病机制及预后关系密切。
he study of 118 bone marrow samples from 59 pa-tients with acute leukemia(AL) was performed histo-chemically, immunohistochemically and morphometri-cally using IBAs-2000 automatic video analyser. Tennormal adults were as control. The result showed thatthere was significant difference in component of extracellular matrix (ECM) of bone marrow between ALand control group. In AL patients , reticulin increased ,acid glycosaminoglycans and fibronectin decreased,neutral glycosaminoglycans increased in previously un-treated patients but decreased in refractory patients.The cell proliferation showed negative and positive re-lated to fibronectin contents in AL and control groups ,respectively. It suggested thatthe development of ALwas related to both the malignant colony hemopoiesisand the alteration of microenviroment ECM.
