Changes of hippocampal neurons after perinatal exposure to ethanol.

The effect of ethanol on the structural development of the central nervous system was studied in offspring of Wistar rats, drinking 20 % ethanol during pregnancy and till the 28th day of their postnatal life. The structural changes in the hippocampus and dentate gyrus were analyzed at the age of 18, 35 and 90 days. A lower width of pyramidal and granular cell layers, cell extinction and fragmen...

Ethanol impairs memory by reducing the synaptic connection of the hippocampal spatial neurons

Background and Objective: Ethanol has undesirable effects on memory and synaptic communication. However, its impact on the learned spatial memory is unclear. We investigated the damaging effects of ethanol on place neurons of rat’s hippocampal CA1.Materials and Methods: Sixty four male Wistar rats (250 g) were administered high (1-8 g/kg) or low (0.05-0.1 g/kg) doses of ethanol intraperit...

Plasticity of GABAA receptors after ethanol pre-exposure in cultured hippocampal neurons.

Alcohol use causes many physiological changes in brain with behavioral sequelae. We previously observed (J Neurosci 27:12367-12377, 2007) plastic changes in hippocampal slice recordings paralleling behavioral changes in rats treated with a single intoxicating dose of ethanol (EtOH). Here, we were able to reproduce in primary cultured hippocampal neurons many of the effects of in vivo EtOH expos...

Glycosylation is altered by ethanol in rat hippocampal cultured neurons.

AIMS Glycoproteins, such as adhesion molecules and growth factors, participate in the regulation of nervous system development. Ethanol affects the synthesis, intracellular transport, distribution, and secretion of N-glycoproteins in different cell types, including astrocytes and hepatocytes, suggesting alterations in the glycosylation process. We analysed the effect of exposure to low doses of...

Thallium stimulates ethanol production in immortalized hippocampal neurons

Lactate and ethanol (EtOH) were determined in cell culture medium (CCM) of immortalized hippocampal neurons (HN9.10e cell line) before and after incubation with Thallium (Tl). This cell line is a reliable, in vitro model of one of the most vulnerable regions of central nervous system. Cells were incubated for 48 h with three different single Tl doses: 1, 10, 100 μg/L (corresponding to 4.9, 49 a...
