The effect of paternal alcohol exposure on neurochemical and behavioral parameters was investigated using as a model system glial cells derived from newborn rat brain and cultured for 4 weeks. The total brain neurochemical parameters from rats born to mothers sired by an alcohol treated father were also investigated. Enzymatic markers of nerve cell(More)
Because of the important role of glial cells in brain maturation and reports on their delayed proliferation following ethanol exposure, it was considered of interest to investigate the mechanism of ethanol action on these cells. Biochemical parameters related to the apoptotic and necrotic processes in astroglial cells exposed for 1 week to 50 and 100 mM(More)
Beneficial effects of St. John's wort (Hypericum perforatum) in the treatment of stress-evoked memory impairment were recently described. In this study, we tested a hypothesis that St. John's wort alleviates stress- and corticosterone-related memory impairments by restoring levels of synaptic plasticity proteins: neuromoduline (GAP-43) and synaptophysin(More)
The effect of acetaldehyde on astrocytes have been investigated because not only do they play an important role in brain maturation but also recent reports have shown their delayed proliferation following both 'in vivo' and 'in vitro' ethanol exposure. Biochemical parameters related to apoptotic and necrotic processes were examined in primary cultures of(More)
Prenatal exposure to alcohol is associated with a cluster of symptoms called Fetal Alcohol Syndrome with a characteristic pattern of neuroanatomy and biochemical changes. In recent years it has been shown, that stress exposed cells rapidly increase transcription and translation of heat shock protein genes resulting in an increased appearance of these(More)
The aim of the study was to investigate the levels of cerebrospinal fluid (CSF) cytokines during chemotherapy of acute lymphoblastic leukaemia (ALL). Examination of 12 ALL child (6 boys and 6 girls) patients evidenced significant increases in interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) after induction treatment and significant increases(More)
In the present study, we investigated the effect of angiotensin IV (Ang IV) on the acquisition of spatial task by rats, expression and function of ryanodine receptors (RyRs) and on Ca(2+) transport in microsomal membranes isolated from rat hippocampus, the brain structure essential for spatial memory.Wistar rats, injected intracerebroventricularly with 1(More)
Sialylated glycoconjugates seem to play crucial role in the mechanisms that control the most important functions of the body. Sialylation is an important mechanism for the regulation of intercellular interactions that underlie neuronal plasticity as well as immune defense in the central nervous system (CNS). In this study, we analyzed the effect of(More)
OBJECTIVE Heat shock proteins assist cellular protein folding and are required for the normal activity of steroid receptors. In this study we assessed nuclear HSP90 and HSP70 proteins and mRNA levels in cells isolated from induced sputum of chronic obstructive pulmonary disease patients treated for 4 weeks with formoterol (F) or formoterol+budesonide(More)
The aim of this work was to assess the role of ethanol-derived acetate and acetate-mediated histone acetylation in arachidonic acid-induced stress in HepG2 cells and cells overexpressing CYP2E1. Cells were grown for 7 days with 1 mM sodium acetate or 100 mM ethanol; their acetylated histone proteins and histone deacetylase 2 expression was quantified using(More)
