[Neurologic complications of aortic dissection]

MÉSZÁROS István, MÓROCZ József, SZLÁVI József, SCHMIDT János, NAGY László, KATÓ Csaba, TORNÓCI László

[Introduction - Beside the damages of the cardiovascular system the lesions of the the nervous system are the most common complications of aortic dissection. This is usually an early event, therefore the dissection of the aorta may manifest itself as an acute primary neurologic disease. The aim of this study is to describe the frequency and distribution of acute neurologic symptoms occurring in aortic dissection and the distribution of their clinico-pathologic features and to establish... tovább »

[Investigation of insertion/deletion polymorphism of the ACE gene on stroke patients]

PONGRÁCZ Endre, TORDAI Attila, CSORNAI Márta, NAGY Zoltán

[Introduction - This is the first Hungarian paper on the insertion/deletion polymorphism of ACE gene in stroke patients. According to literature data, the role of this polymorphism is controversial in the pathogenesis of stroke. The aim was to study the prevalence of the polymorphism in healthy persons and in stroke patients. Patients and methods - Blood samples from 173 unrelated healthy donors and 253 stroke patients were investigated by polymerase chain reaction (PCR). Preivous stroke was... tovább »

[β-amyloid peptide-induced intracellular calcium level changes in Alzheimer fibroblasts]

PALOTÁS András, KÁLMÁN János, LASKAY Gábor, JUHÁSZ Anna, JANKA Zoltán, PENKE Botond

[Rationale - β-amyloid peptides, comprising the major neuropathological lesions of Alzheimer's disease, have been found to form depositions in various peripheral tissues, including the skin. Neurons in the disorder succumb to the altered ionic homeostasis and some other factors caused by this toxic peptide. In line with these findings, our study aimed to find differences in biochemical processes of cultured cutaneous fibroblasts derived from sporadic Alzheimer patients and from agematched... tovább »

[MR examination of thoracic herniation of the spinal cord]

KENÉZ József, BARSI Péter, VÁRALLYAY György, BOBEST Mátyás, VERES Róbert

[Transdural herniation of the spinal cord is thought to be previously extremely rare and very often misdiagnosed. Possible reasons may be iatrogenic and traumatic or in about one third of cases it may be unknown, where the probable origin might be a congenital dural defect. The pathology may show characteristic and misleading MR patterns of the thoracic spine, emphasising the importance of these patterns. This anomaly can lead to progressive Brown-Sequard syndrome. Surgical intervention,... tovább »

[Identification of gliomas by morphological and immunocytochemical analysis in cell cultures]

FAZEKAS Ilona, KEREKES Edit, HEGEDŰS Balázs, NYÁRY István

[Introduction - The morphology and immunocytochemical properties of 250 different monolayer cultures derived from various human brain tumor specimens were investigated on purpose to support and complement the neuropatholgical diagnosis. In this study analyses of 124 glioma cases are presented. Methods - The tumor samples were mechanically dissociated and seeded on glass coverslips. After the formation of the monolayer cultures were fixed and stained by May-Grünwald- Giemsa method for the... tovább »

[Electrophysiological investigations in Parkinson’s diseae]

SZIRMAI Imre, GERTRÚD Tamás, TAKÁTS Annamária, PÁLVÖLGYI László, KAMONDI Anita

[Objective - Post-movement beta synchronization is an increase in EEG beta power after movement termination. Its characteristics in movement disorders are not well described. Tremor dominant Parkinson’s disease shows unique clinical, anatomical and biochemical features. In our study we examined the relation between the laterality of tremor and size of post-movement beta synchronisation in tremor dominant Parkinson’s disease. Methods - In a self-paced movement paradigm we measured movement... tovább »
