目的:观察针刺对多发梗塞性痴呆大鼠海马NF-κB和IκB蛋白表达的影响,探讨针刺治疗多发梗塞性痴呆的作用机制。方法:通过栓子注入法制作多发梗塞性痴呆模型,造模成功大鼠随机分为模型组、针刺组和非穴组,并设正常组和假手术组。针刺处理3周后,运用免疫组化方法分析海马NF-κB和IκB的蛋白表达水平。结果:与正常组相比,模型组海马NF-κB及IκB蛋白表达显著升高。同时,针刺组大鼠海马NF-κB、IκB蛋白表达水平明显高于模型组。结论:针刺能够增强多发梗塞性痴呆大鼠海马NF-κB、IκB的蛋白表达水平,发挥神经保护作用,改善痴呆动物的学习记忆能力。  相似文献

Minaprine, an aminopyridazine derivative, represents a new class of antidepressants; in addition minaprine has been shown to possess cholinomimetic properties in rodents. Thus it seemed of interest to study the efficacy and tolerance of minaprine in the treatment of depressed mood, behavioural impairment and cognitive deterioration of senile dementia. A total of 122 patients were included in this three-month, randomized, double-blind, placebo-controlled, multicentric trial; 63 patients suffered from senile dementia of Alzheimer's type (SDAT) and 59 from multi-infarct dementia (MID). In both SDAT and MID, minaprine (100 mg bid) was more effective than placebo in relieving depressed mood. In some MID patients, minaprine also improved behavioural impairment. In SDAT patients, minaprine seemed to improve some aspects of cognitive function, as judged by a limited battery of psychometric tests. Overall, minaprine appeared to be more effective in MID, although longer treatment and/or higher dosage may be necessary in SDAT. The incidence of side-effects was low in both treatment groups.  相似文献

目的:研究AD和MID患者脑影像学改变与认知障碍之间的关系。方法:调查112例门诊和住院AD和MID患者,测定脑C19项指标和MMSEI 1项因子。结果:AD组三、四脑室、基底池、外侧裂、前后角、脑沟及侧脑室的宽度大于MID组,时间地点定向力、语言即刻记忆、注意和计算及图形描画等5项因子分明显低于MID组;AD组三、四脑室、前角和侧脑室宽度分别与地点定向、注意计算、阅读和语言理解因子分呈显著负相关;MID组后角、三脑室、侧脑室及脉络丛球部宽度分别与时间、定向、阅读理解及图形描画因子分呈显著负相关。结论:AD患者脑室系统扩大和认知损害程度比MID患者严重而广泛。MMSE测查结果结合有关病史是MID早期诊断及与AD鉴别诊断的重要依据。  相似文献

Summary Autopsied brains from 55 patients with dementia between 59–95 years of age (mean age 77.9±8.1 years) and 19 non-demented individuals between 46–91 years of age (mean age 74.3±10.5 years) were examined to establish histopathological criteria for normal ageing, primary degenerative [Alzheimer's disease (AD)/senile dementia of Alzheimer type (SDAT)] and vascular (multi-infarct) dementia (MID) disorders. Senile/neuritic plaques, neurofibrillary tangles, microscopic infarcts and perivascular serum protein deposits were quantified in the frontal lobe (Brodmann area 10) and in the hippocampus. The demented patients were classified according to the DSM-III criteria into AD/SDAT and MID. Operationally defined histopathological criteria for dementias, based on the degree/amount of the histopathological changes seen in aged non-demented patients, were postulated. The demented patients were clearly separable into three histopathological types, namely AD/SDAT, MID and AD-MID, the dementia type where both the degenerative and the vascular changes are coexistent in greater extent than are seen in the non-demented individuals. Using general clinical, gross neuroanatomical and histopathological data three separate dementia classes, namely AD/SDAT, MID and AD-MID, were visualized in two-dimensional space by multivariate data analysis. This analysis revealed that the pathology in the AD-MID patients was not merely a linear combination of the pathology in AD/SDAT and MID, indicating that AD-MID might represent a dementia type of its own. The clinical diagnosis for AD/SDAT and MID was certain in only half of the AD/SDAT and one third of the MID cases when evaluated histopathologically and by multivariate data analysis. AD/SDAT, MID and AD-MID were histopathologically diagnosed in 49%, 24% and 27%, respectively, of all the dementia cases studied. Opposite correlation between the number of tangles, plaques and the patient age in non-demented and AD/SDAT cases were observed, indicating that the pathogenesis of tangles and plaques in the two groups of patients might be different and that AD/SDAT might not be a form of an exaggerated ageing process.  相似文献

Summary Cerebral glucose metabolism of 18 patients with multi-infarct dementia (MID) and 10 age-matched normal subjects were examined with positron emission tomography and the18-F-fluoro-deoxy-glucose technique. MID patients had significantly lower glucose metabolism in all the grey matter regions measured and were also characterized by more individuality in metabolic pattern. MID patients were also evaluated as to intelligence quotient (IQ). A positive correlation between IQ as shown by the Tanaka-Binet test and glucose metabolism for the entire grey matter was found. The clinical applicability of this test for predicting cerebral metabolism is discussed.  相似文献

Morphometric analysis of thrombocytes from patients with Alzheimer's disease, from patients with multi-infarct dementia, and from young and agematched healthy control donors, did not reveal any Alzheimer-related increase in internal membranes. Biochemical analysis showed a reduced cholesterol content of thrombocyte membrane preparations from Alzheimer patients relative to age-matched controls, but not relative to multi-infarct dementia patients. Overall distribution of protein kinase C activity (PKC) between cytosol and membrane, in resting as well as in activated thrombocytes from Alzheimer patients, was similar to that in the control groups. However, both Alzheimer and multi-infarct dementia patients had lower cytosolic levels of basal kinase and PKC activities than age-matched controls, while only Alzheimer patients had lower cytoskeletal PKC activity than controls.  相似文献

The concept of vascular dementia remains controversial. Indeed, in many instances what is called vascular dementia may neither be vascular nor dementia. However, while overdiagnosis may be frequently made, underrecognition of vascular factors in dementia also seems common. Recent works show that focal/multifocal cognitive and executive dysfunction which may follow sequential or more rarely single-strategic stroke should be differentiated from more diffuse progressive intellectual decline mimicking a degenerative disorder (such as Alzheimer's disease) which may smoothly develop in over one fourth of stroke patients.  相似文献

A double-blind placebo-controlled trial of the calcium antagonist Nimodipine in 10 patients with multi-infarct dementia (MID) shows that there is no improvement when compared with 10 patients on placebo assessed by clinical ratings and sequential NMR imaging. The value of repeated NMR imaging in measuring changes in MID is described.  相似文献
