AIMS The effect of 'binge drinking' coupled or not with chronic nicotine administration on nucleus accumbens (NAc) glutamate, arginine, taurine and hydroxyl radical levels has been investigated in these present studies. METHODS AND RESULTS Ethanol, 2 or 3 g/kg, has been administered to male or female adult rats in a 'binge-type' regime for 3 weeks, +/- nicotine, and changes in glutamate, argi...

Morinda citrifolia is a member of the Rubiaceae. It is a Shrub or compacted to twisted small tree up to 8 m high with square stems and large stipules between nodes and petioles. Leaves are opposite, petiolate, glossy, mostly ovate, 15-35 cm long. Flowers white, up to 15 mm long, with a tubular corolla and 5 spreading lobes, the flowers borne on a globose syncarp. Fruit a large fleshy syncarp up...

The developing brain is vulnerable to the effects of ethanol. Glutamate is the main mediator of excitatory signals in the brain and is probably involved in most aspects of normal brain function during development. The aim of this study was to investigate vulnerability to and the impact of ethanol toxicity on glutamate uptake signaling in adolescent rats after moderate pre and postnatal ethanol ...

Iron can potentiate the toxicity of ethanol. Ethanol increases the content of cytochrome P450 2E1 (CYP2E1), which generates reactive oxygen species, and transition metals such as iron are powerful catalysts of hydroxyl radical formation and lipid peroxidation. Experiments were carried out to attempt to link CYP2E1, iron, and oxidative stress as a potential mechanism by which iron increases etha...

Background and objectives: Solanum trilobatum plant parts such as berries and flowers are normally used for the treatment of respiratory illnesses. The toxicity profile of the plant and its parts are not clear. Hence, the present study was planned to investigate the toxicological effects of ethanol extract of leaves of S. trilobatum (EEST) using acute and sub-...

background t-2 toxin is a mycotoxin, exposure to which causes dermal and systemic toxicity. crataegus pontica (a member of the rosaceous family) is a small tree with caduceus foliage that is widely distributed throughout the western and central areas of iran. objectives this study was performed to examine the healing effects of creams prepared using crataegus pontica leaf extract on dermal toxi...

The mechanisms underlying alcoholic liver disease are not completely understood, but lipid accumulation seems to be central to the cause of this disease. The peroxisome proliferatoractivated receptor (PPAR ) plays an important role in the control of lipid homeostasis, metabolism of bioactive molecules, and modulation of inflammatory responses. To investigate the roles of PPAR in alcoholic liver...

Autophagy is an intracellular pathway by which lysosomes degrade and recycle long-lived proteins and cellular organelles. The effects of ethanol on autophagy are complex but recent studies have shown that autophagy serves a protective function against ethanol-induced liver injury. Autophagy was found to also be protective against CYP2E1-dependent toxicity in vitro in HepG2 cells which express C...

Effects of ethanol on the gastrointestinal tract are reviewed, and an overview of possible mechanisms of ethanol damage to the alimentary tract is presented. Ethanol toxicity most commonly results in metabsorption. Mechanisms contributing to ethanol-induced calcium malabsorption are considered in detail as a prototype for problems encountered in evaluating effects of toxicants on intestinal fun...

Alcohol intoxication results in neuronal apoptosis, neurodegeneration and manifest with impaired balance, loss of muscle coordination and behavioral changes. One of the early events of alcohol intoxication is mitochondrial (Mt) dysfunction and disruption of intracellular redox homeostasis. The mechanisms by which alcohol causes Mt dysfunction, disrupts cellular redox homeostasis and triggers ne...
