不同吸氧方式对小鼠骨髓放射效应的影响

①目的 探讨在直线加速器照射下,低浓度氧吸入、碳合氧吸入以及高-低氧吸入等三种不同的方式对小鼠骨髓细胞放射生物效应的影响。②方法 昆明小鼠随机分为空气组,高氧组,低氧组,高-低氧组。用6MV-X线不同剂量全身单次照射,配合剂量效应曲线,求出不同吸氧方式的放射防护系数（RPF）并用图像分析仪测定白细胞介素-3（IL-3）基因蛋白相对含量。③结果 高氧组碳合氧的吸入显示了放射增敏作用,其RPF为0.86,低氧组低氧放疗具有放射防护作用,其RPF为1.41,高-低氧组高-低氧放疗也表现出一定的放射防护作用,RPF为1.09;高-低氧组与空气组IL-3基因蛋白的表达差异无统计学意义（F=5.37,q=2.87,P〉0.05）,而高氧组和低氧组与空气组相比,IL-3基因蛋白的表达分别减少和增加,差异有统计学意义（q=3.37、4.23,P〈0.05）。④结论 IL-3的免疫组化定量表达可能是辐射所致骨髓早期损伤的分子标志。高-低氧放疗可消除高氧加重的骨髓辐射损伤,在一定程度上具有放射防护作用。     

Recombinant human Flt3 ligand exerts both direct and indirect effects on hematopoiesis

Objective To investigate the direct effects of the Flt3 ligand (FL) on hematopoiesis, such as the stimulation of the formation of hematopoietic colonies and the proliferation of dendritic cells, as well as the indirect stimulation of hematopoiesis, especially via the proliferation of endothelial cells.Methods Mononuclear cells from human cord blood were plated in methylcellulose medium containing different cytokines to induce hematopoietic colony formation. Dendritic cells (DCs) were induced from the mononuclear cells with a cytokine cocktail with or without recombinant human soluble FL (rhFL; 100ng/ml).The Flt3 receptors on the surface of a human microvascular endothelial cell line (ECV) were analyzed by flow cytometry. The proliferation of ECV stimulated by rhFL was measured with the microculture tetrazolium assay. The levels of FL, IL-6, IL-8, G-CSF and GM-CSF in the supernatant of ECV cultures were measured by enzyme linked immunoabsorbent assay (ELISA).Results rhFL stimulates colony formation from cord blood when used as a sole stimulant. FL in combination with other cytokines increased colony formation significantly. The number of DCs was approximately 2.5 times higher when rhFL was used. rhFL stimulates the proliferation of ECV on which Flt3 receptors are expressed. Furthermore, ECV secretes FL, IL-6, IL-8, G-CSF and GM-CSF, which were augmented by tumor necrosis factor-α and rhFL.Conclusions rhFL enhances hematopoietic colony formation and DC proliferation from human cord blood cells.

具骨髓间充质干细胞表型的成体干细胞移植造血

目的为了探索骨髓成体干细胞是否能重建超致死剂量射线照射后小鼠的造血功能.方法采用液体培养分离,培养,扩增雄性小鼠骨髓成体干细胞,作为供体细胞,将受体雌性小鼠预先经Cs137全身照射850rad后在4 h内从尾静脉输入细胞.受体小鼠分为5组,每组10只a正常小鼠不经任何处理;b输入6×106cell/只(0.3ml)新鲜全骨髓;c输入6×106 cell/只(0.3 m1)去基质细胞的造血细胞;d输入6×106cell/只(0 3 m1)经培养后的成体干细胞,输注细胞后第1天上、下午肌肉注射各一次Granulocyte colony stimulating factor(G-CSF)等细胞因子;e注射D-Hanks液0.3ml/只.观察各组小鼠的存活情况,小鼠在输注前查尾静脉血,计细胞总数、涂片、分类,输细胞后每周各组分别取小鼠肝、脾、股骨,固定作病理切片,另外一侧股骨冲出骨髓,计数一条股骨有核细胞数、涂片、测定colonyforming unit-granulocyte/macrophage(GM-CFU)值.结果输全骨髓组外周血有核细胞和骨髓有核细胞数及GM-CFU值在输注后的第1,2周都高于单输成体干细胞组,但单输基质细胞组有核细胞逐渐恢复,小鼠存活好,至输注后第3周,无论外周血或骨髓中的有核细胞都较第2周明显恢复,GM-CFU也明显升高,而单输造血细胞和D-hnks液组小鼠存活7～8 d死亡.结论小鼠超致死剂量照射后,输入经培养后的同种小鼠骨髓成体干细胞配合G-CSF等细胞因子注射可重建小鼠造血功能.     

小鼠骨髓基质细胞形态及其对造血的调控

应用体外骨髓基质细胞贴壁培养的方法,观察了小鼠骨髓贴壁细胞的形态及其对造血的调控作用。结果表明,两类大小、形态、吞噬功能及组化染色有所差异的基质细胞群体分别具有巨噬细胞和成纤维细胞样特征。贴壁细胞对粒—单系祖细胞的增殖表现为明显的刺激作用,而对多能造血干细胞无明显调控。提示骨髓基质细胞在造血祖细胞阶段的分化增殖过程中具有一定作用。     

用小鼠骨髓内皮细胞条件培养液代替造血刺激因子培养CFU— …

利用大于１０ｋＤ组分的小鼠骨髓内此细胞条件培养液（ｍＢＭＥＣ－ＣＭ）作刺激物体外琼脂培养ＣＦＵ－ＧＭ,与ｍＧＭ－ＣＳＦ合用培养ＨＰＰ－ＣＦＣ获得成功。就培养ＣＦＵ－ＧＭ和ＨＰＰ－ＣＦＣ而言,用细胞因子作刺激物与并用大于１０ｋＤ组分的ｍＢＭＥＣ－ＣＭ作刺激物相比较,以后者的ＣＦＵ－ＧＭ及ＨＰＰ－ＣＦＣ产率最高。     

First use of G-CSF in chlorpromazine-induced agranulocytosis: a report of two cases.

Chlorpromazine-induced agranulocytosis is an uncommon disorder associated with a high frequency of fatality. We describe two patients with chlorpromazine-induced granulocytosis in whom granulocyte colony stimulating factor (G-CSF) administration enhanced the speed of neutrophil recovery. No toxicity was noted with G-CSF and both patients made a successful recovery. We propose there is a role for such cytokine therapy in patients with life-threatening agranulocytosis in order to speed the recovery of neutrophils.     

芍药苷对放射线致血虚证小鼠骨髓Epo和G-CSF基因表达的影响

目的:考察芍药苷对放射线致血虚证小鼠的生血作用及对骨髓Epo、G CSF基因表达的影响,为阐明芍药苷补血作用的分子机制提供依据。方法:采用3.5Gy60 Coγ射线全身1次性照射,制备小鼠血虚证模型,检测外周血象,骨髓集落培养观察并计数CFU GM、BFU E、CFU E、CFU mix ,RT PCR观察并检测骨髓Epo和G CSF基因表达。结果:芍药苷显著升高放射线致血虚证小鼠外周血白细胞数量和骨髓CFU GM、BFU E、CFU E、CFU mix数量,上调骨髓Epo和G CSF基因表达。结论:芍药苷具有生血作用,促进骨髓Epo和G CSF基因的表达可能是其生血作用的机制之一。
