MBP对PBMC产生IFN-γ和NO的影响

目的探讨T细胞非特异性活化在CNS脱髓鞘性疾病中的作用。方法分离实验性自身免疫性脑脊髓炎(EAE)易感性BALB/c小鼠外周血单个核细胞(PBMC),采用体外细胞培养方法在体外与碱性髓鞘蛋白(MBP)共培养,测定培养上清液中IFN-γ、NO水平。结果经MBP刺激的PBMC产生IFN-γ[(43.83±6.06)pg/mL]和NO[(180.76±20.75)μmol/L]明显增加,与对照组产生的IFN-γ[(28.52±2.18)pg/mL]和NO[(95.61±13.09)μmol/L]相比差异有统计学意义(P<0.01)。结论在CNS脱髓鞘性疾病发病过程中,活化的T细胞、单核细胞等分泌致炎细胞因子和其他有害物质增多。     

急性脑血管病患者血清髓鞘碱性蛋白含量研究

用酶联免疫吸附法对３０例急性脑血管病（ＣＶＤ）患者及３２位正常人血清髓鞘碱性蛋白（ＭＢＰ）含量进行检测。结果表明：急性ＣＶＤ组患者血清ＭＢＰ含量显著高于正常人组（Ｐ＜０．０１）；血清ＭＢＰ含量与急性ＣＶＤ的严重程度相关。提示检测血清ＭＢＰ含量对急性ＣＶＤ诊断及预后判断有重要价值     

脑塞患者血清髓鞘碱性蛋白测定及临床意义

测定急性脑梗塞患者血清髓鞘碱性蛋白含量变化，探讨其临床意义，方法：采用酶联免疫吸附检测法测定了４２例急性脑梗塞患者血清ＭＢＰ含量，并对其中３８例患者进行了动态观察。     

肾移植术后脑桥中央髓鞘溶解症2例报告

桥脑中央髓鞘溶解症(central portime myclinolysis,CPM)病因目前尚不明确,肾移植术后出现本病实属罕见,现将我们收治2例报告如下.     

垂体瘤术后脑桥外髓鞘溶解症

脑桥外髓鞘溶解症(extropontine myelinolysis EMP)是一种罕见的疾病，其特征是在脑的某些特定区域出现脱髓鞲改变。最常受累的部位是基底节和丘脑，患者多表现为行为异常和锥体外系的症状和体征，本病发病机制不清，多数学者认为EPM是由于血钠水平迅速改变使脑组织承受较大梯度的渗透压改变而致。     

脑桥外髓鞘溶解症MRI表现(附1例报告)

脑桥外髓鞘溶解症（extropontine myelinolysis EPM）是少见病，国内报道很少．现报告1例经MRI确诊病例。     

血浆置换术治疗格林—巴利综合征12例

格林—巴利综合征(GBS)是一组累及周围神经髓鞘的自身免疫性神经病，可伴有植物神经症状和呼吸衰竭，若不及时抢救治疗可导致死亡，我们用CS—3000Plus细胞分离机对重型和极重型GBS患者，配合临床进行了12例抢救治疗，取得了良好的治疗效果。现报告如下：     

急性脑血管病患者血清及脑脊液髓鞘碱性...

Myelin basic protein (MBP) was measured in the serum and CSF of patients with acute cerebrovascular disease (CVD, 34 cases), demyelinating disorders (DMD, 30 cases) and other neurological diseases (OND, 26 cases) by using a double antibody radioimmunoassay (RIA). Patients with acute CVD had a mean serum MBP concentration and positivity rate much higher than those with DMD and OND. The differences were significant (P < 0.05). In CSF, MBP levels in patients with acute CVD and patients with DMD were significantly greater than those in OND patients (P < 0.05). The results also show that there was a linear relationship between the CSF MBP levels and the serum MBP levels in patients with acute CVD (r = 0.72, P < 0.01), but no such relationship in patients with DMD and OND. The amount of serum MBP was also significantly correlated to the severity of acute CVD, to the level of consciousness disorder and limb paralysis, and to the extent and site of the cerebral lesion at CT-scan (P < 0.05). This study shows that the measurement of brain specific MBP in serum as a marker of cerebral damage may have clinical value in the diagnosis and prognosis of patients with CVD.
