检测了34例动脉硬化性脑血管病患者(脑出血16例、脑缺血18例)急性发病后1.5~6d内外周血血清(S)IgG、IgA、IgM、C3、C4、CH50与脑脊液(CSF)白蛋白(Alb)以及CSFIgG/SIgG比值,并与20名患动脉硬化的“正常人”(无其他疾病)进行了比较。结果表明:(1)外周血IgG、C3、C4、CH50两组患者较正常人明显增高,两组患者间无显著性差异;三组间IgA、IgM无显著性差异。(2)CSF中IgG两组患者均增高,且出血组更明显;CSFIgG/SIgG比值出血组较缺血组明显增高;两组Alb均增高,出血组更明显。提示该病发病后体液免疫增强,这可能是伴发肺部感染的免疫病理机制之一。出现血脑屏障功能损害且脑出血较缺血更为严重,并可能有IgG的内源性合成,提示急性脑组织损伤后中枢神经系统的免疫应激反应以及中枢神经系统结构的完整性与免疫应答密切相关。上述外周血与CSF各项指标测定结果的不同,说明神经免疫学的特殊性。  相似文献

Serum and CSF immunological findings in ALS   总被引:2,自引:0,他引:2  
Serum and CSF immunological findings were analysed in 37 patients with amyotrophic lateral sclerosis (ALS). ALS patients had significantly higher mean values of serum IgG and complement component C4 and significantly lower mean value of total haemolytic titre of complement (THC) compared with normal controls. Incidence of immune complexes (ICs) was significantly higher in sera of ALS patients than in normal controls. There was no significant difference regarding mean serum levels of IgM, IgA, and complement components C3 and Factor B between patients and controls. The blood-brain barrier (BBB) damage was found in 46% of patients. Intrathecal IgG synthesis was detected in six patients (16%). These results support the hypothesis of immune system involvement in ALS.  相似文献

The scavenger receptor class B type I gene can protect against atherosclerosis; a mononucleotide polymorphism is associated with differences in blood lipid metabolism, postprandial serum lipid levels, insulin resistance, coronary artery disease and familial hyperlipidemia. In this study, the scavenger receptor class B type I gene exon 1 G4A gene polymorphism in atherosclerotic cerebral infarction patients, cerebral hemorrhage patients and normal controls was detected using the polymerase chain reaction-restriction fragment length polymorphism method. The results showed that the GA + AA genotype frequency of scavenger receptor class B type I gene G4A in atherosclerotic cerebral infarction patients was similar to that in cerebral hemorrhage patients and normal controls; however, the A allele frequency was significantly lower than that in normal controls. The serum level of high-density lipoprotein cholesterol in patients with the scavenger receptor class B type I gene G4A GA + AA genotype was significantly higher, while the serum level of low-density lipoprotein cholesterol was significantly lower than that in patients with the GG genotype, in both the atherosclerotic cerebral infarction and cerebral hemorrhage groups. The serum level of high-density lipoprotein cholesterol in patients with the scavenger receptor class B type I gene G4A GA + AA genotype was significantly higher, while the serum levels of low-density lipoprotein cholesterol and total cholesterol were significantly lower than those in normal controls with the GG genotype. Our experimental results suggest that the G4A polymorphism of the scavenger receptor class B type I gene is a possible predisposing risk factor for atherosclerotic cerebral infarction, and that it has no association with cerebral hemorrhage in the Han population in Hunan province of China. The A allele is possibly associated with the metabolism of high-density and low-density lipoprotein cholesterol.  相似文献

脑血管疾病患者血清TNF,IL—8的变化及临床意义   总被引:9,自引:0,他引:9  
目的观察脑血管病患者血清肿瘤坏死因子(TNF)、白细胞介素-08(IL-8)水平的动态变化。方法采用ELISA法分别测定95例脑血管病患者起病<1周及≥4周的血清TNF、IL-8水平。结果脑血管病患者血清NNF、IL-8水平较正常对照组增高,起病<1周者血清TNF、IL-8水平较≥起病4周者升高显著;起病≥4周者脑梗死组血清TNF、IL-8和脑出血组TNF有明显下降,但仍高于正常对照组,脑出血组IL-8与正常对照组无明显差异。结论血清IL-8、TNF水平的动态监测对脑血管疾病(CVD)发生、发展及其预后判断具有一定预测价值。  相似文献

目的探讨雌激素对绝经后妇女脑梗死及血脂水平的影响。方法 用放射免疫分析法和全自动生化分析仪测定50例绝经后妇女脑梗死患者及24例正常人血清E2、TC、TC、HDLC、LDL-C水平。结果 绝经后老年与非老年组脑梗死患者血清E2和HDLC水平均明显低于对照组,而TC、TC、LDLC水平均明显高于对照组(P<0.05~P<0.01)。上述各指标,以老年组改变为最明显,与非老年组相比有显著性差异(P<0.05)。同时老年组有多灶梗死者也明显多于非老年组(P<0.05)。相关分析,E2与IC、IC、LDLC呈负相关,与HDL-C水平呈正相关。结论 绝经后妇女脑梗死患者血清雌激素水平降低是导致脂代谢紊乱及脑梗死发生的主要危险因素。  相似文献

Abstract: The possibility of immunological mechanisms causing headaches has been proposed in the past. To investigate the immunological system activation in patients with chronic headaches, we evaluated the k/Λ ratios of immunoglobulins in 40 : patients with migraine and 49 : patients with tension-type headache. Nineteen healthy volunteers composed the control group. The serum k and Λ levels of immunoglobulins were determined by using the enzyme-linked immunosorbent assay (ELISA) techniques. The k/Λ ratios of IgG in the patients with tension-type headache were sigaiflcantly higher than those in the controls. The k/Λ ratios of IgA and IgM in the patients with headaches were higher than those in the controls, but they were not statistically significant. The total concentrations of IgG, IgA and IgM were significantly higher in the patients with migraine. In the patients with tension-type headache, the total concentrations of IgG and IgA were sigaificantly higher than those in the controls. The high levels of k/Λ ratios of IgC in the patients with tension-type headache and the increase in the total concentrations of immunoglobulins in the patients with migraine and tension-type headache, observed in this study, suggest that the humoral immunological system activation might exist, and it might be related to the etiology of tension-type headache and migraine.  相似文献

Symptoms of respiratory tract disease were recorded for half a year in 32 epileptic patients receiving phenytoin, and in 25 controls. There were 16 patients with normal IgA concentration in serum and nasal secretion, and 16 with a reduced concentration of IgA either in serum or in nasal secretion, or in both. Both groups of patients had significantly more frequent respiratory symptoms than did the controls ( P < 0.01). There was no difference when the patient group with decreased IgA concentrations was compared to that with normal IgA levels. All the four patients with IgA deficiency both in serum and nasal secretion had, however, more frequent symptoms than any of the controls. There was no difference regarding respiratory tract disease in patients taking phenytoin only, compared to those combining phenytoin and other anticonvulsants. IgG and IgM levels in nasal secretion showed no direct relationship to the frequency of respiratory symptoms.  相似文献

目的探讨重型颅脑损伤病人早期实施肠内营养对免疫功能及并发症的影响。方法对168例重型颅脑损伤病人(GCS≤8分)半随机分为肠内营养组(EN组)和肠外营养组(PN组),每组84例。用免疫组化法测定两组患者在入院后10d血清中IgG、IgA、IgM及IgE含量及T淋巴细胞亚群CD4+、CD8+、CD4+/CD8+值,对比两组的免疫功能变化。结果重型颅脑损伤后病人免疫功能明显下降,而EN组患者血清中的IgG、IgA、IgM显著高于PN组(P0.05);CD4+水平及CD4+/CD8+比值明显高于PN组(P0.05);IgE明显低于PN组(P0.05)。EN组的并发症发生率明显低于PN组(P0.05)。结论重型颅脑损伤病人可导致机体免疫功能下降,早期肠内营养支持可提高人体免疫功能,减少并发症的发生。  相似文献
