AIMS Caffeine is a central nervous system stimulant that produces its primary effects via antagonism of the A(1) and A(2A) adenosine receptor subtypes. Previous work demonstrated a sex difference in neurotoxicity produced by specific adenosine A(1) receptor antagonism during ethanol withdrawal (EWD) in vitro that was attributable to effects downstream of A(1) receptors at NMDA receptors. The cu...
Medicinal plants in genus Lagerstroemia were investigated for phytochemical contents by GC-MS and HPLC with ethanol and hexane extracts and their toxicity MTT and comet assay on human peripheral blood mononuclear cells (PBMCs). γ-Sitosterol is the major component found in all species at 14.70-34.44%. All of the extracts, except for L. speciosa ethanol extract, showed high percentages of cell vi...
To determine whether aqueous and ethanol fractions of the Angelica keiskei leaf exert toxicity when used for cosmetic purposes, we performed the acute eye irritancy test. Animals were treated with sample fractions (100 mg/dose) according to standard procedure guidelines. No significant changes or damage was detected in the fraction-treated groups in terms of ocular lesions in the cornea, the si...
This study compared the effects of toxicity of ethanol and its first metabolite acetaldehyde in rat astrocytes through cell viability and cell proliferation. The cells were treated with different concentrations of ethanol in the presence or absence of a catalase inhibitor 2-amino-1,2,4 triazole (AMT) or with different concentrations of acetaldehyde. Cell viability was assessed using the trypan ...
AIM Ethanol causes oxidative degradation of the mitochondrial genome in the brain. This effect could contribute to the development of brain injury in some alcoholic patients. We investigated the protective effect of caffeic acid phenyl esther (CAPE) and intralipid (IL) on oxidative stress and neurotoxicity induced by ethanol intake. MATERIAL AND METHODS The forty-eight rats were randomly divi...
We compared the preventive capacity of high intakes of vitamin C (VC) and vitamin E (VE) on oxidative stress and liver toxicity in rats fed a low-fat ethanol diet. Thirty-two Wistar rats received the low fat (10% of total calories) Lieber-DeCarli liquid diet as follows: either ethanol alone (Alc group, 36% of total calories) or ethanol in combination with VC (Alc + VC group, 40 mg VC/100 g body...
Ethanol consumption has well-known deleterious effects on memory. However, the mechanism by which ethanol exerts its effects on memory has received little attention, which has retarded the identification and development of effective therapeutic strategies against ethanol toxicity. The aim of this study was to explore the neuronal mechanisms underlying the protective action of curcumin, a natura...
We have shown that 17beta-estradiol protects against ethanol withdrawal toxicity in rats. Here, we investigated whether a cellular model of ethanol withdrawal could be developed in a cultured hippocampal cell line (HT22) and whether an adamantyl-containing nonfeminizing estrogen analog, ZYC26 [(3-hydroxy-2-adamantyl(1)-4-methyl-estra-1,3,5(10)-17-one], protects against ethanol withdrawal toxici...
Previous studies using cell and whole embryo cultures have shown that free radicals play an important role in the ethanol-induced death of mouse neural crest cells (NCCs; a significant cell type with respect to the genesis of alcohol-related birth defects). This investigation was spurred by reports of increased iron in ethanol-exposed fetuses and the knowledge that iron can initiate the product...
BACKGROUND There is mounting clinical evidence that ethanol toxicity to the pancreas is linked with glutathione depletion from oxidative stress but there is not experimental proof that this occurs. AIMS AND METHODS The effect of acute ethanol ingestion (4 g/kg) on the pancreatic content of reduced (GSH) and oxidised (GSSG) glutathione, malondialdehyde (MDA), and carbonyl proteins were therefo...
