Schizophrenia is a social disease that occurs in 0.5-1% of the population. It shows a high variability in both clinical picture and theory of its pathogenesis. Its clinical manifestations are accompanied by biochemical, immunological and structural changes. A pivotal role in the development of psychotic disorders is attributed to the impaired limbic system.(More)
We report a 18-year-old female patient with livedo reticularis and neurological disturbances. CT scan showed two big ischemic focuses in the pons, moreover MRI revealed small disseminated ischemic focuses in the pons and deep structures of both brain hemispheres. MRA demonstrated no changes in the big extracranial and intracranial arteries. Since the(More)
Three patients (of two unrelated Polish families) with early-adult onset dementia were subjects of the study. Two cases, previously diagnosed as familial Alzheimer's disease (FAD) with cerebral amyloid angiopathy (CAA), were confirmed by genetic and neuropathological studies, and one case of CADASIL was ultrastructurally confirmed by the presence of(More)
Under pathological conditions, microglial cells undergo activation, which is manifested by the expression of histocompatibility locus antigens class II (HLA II) on their surface as well as by proliferation and varied morphological forms. In schizophrenia, characterised by an essential role played by immunological mechanisms, quantitative analysis of(More)
A study of microglial activation and its contribution to the CNS immune response was performed on the brain autopsy material of 40 patients with definite sporadic Creutzfeldt-Jakob disease (sCJD). Spatial patterns of microglial activation and prion protein disease-associated (PrPd) deposition were compared in cerebellar and cerebral cortices using(More)
Ultrastructural analysis of the skeletal muscle in adult-onset Pompe disease revealed lysosomal and cytoplasmic glycogen storage, autophagic vacuoles and abnormal mitochondria. Significant glycogen accumulation within lysosomes causes their rupture and release of glycogen into the cytoplasm. Excess cytoplasmic glycogen could lead to damage of the structure(More)
Glycogen storage disease type II (GSD II) is an autosomal recessive deficiency of acidalpha-1,4-glucosidase(GAA) caused by mutations in the GAA gene located on human chromosome 17 (17q 25.2-q 25.3). Although its pathophysiology is partially understood, it has not yet been elucidated whether the level of GAA deficiency is directly proportional to the level(More)
Alcohol ingestion by female rats during pregnancy and/or lactation leads to developmental anomalies of different organ systems, retardation and immune system impairment in their offspring. In humans, these disorders are termed foetal alcohol syndrome (FAS), or foetal alcohol effect (FAE) if abnormalities are of lesser degree. The study materials consisted(More)
This report presents a case of widespread intramedullary giant cell ependymoma arising from the central canal of the C4 segment of the spinal cord in a 28-year-old man admitted to hospital with tetraplegia and signs of increased intracranial pressure, eight months after surgical spinal cervical decompression without tetraplegia improvement. Magnetic(More)
CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy) is an inherited systemic vascular disorder affecting mainly the central nervous system. We performed detailed ultrastructural examination of the small vessels in the skin and skeletal muscle of a 51-year-old patient with bilateral cerebral white matter(More)
