Alcohol abuse is associated with both acute and chronic pancreatitis. Repeated episodes of acute pancreatitis or pancreatic injury may result in chronic pancreatitis. We investigated ethanol-induced pancreatic injury using a mouse model of binge ethanol exposure. Male C57BL/6 mice were exposed to ethanol intragastrically (5 g/kg, 25% ethanol w/v) daily for 10 days. Binge ethanol exposure caused...
A potential in vitro model for studying the mechanisms of alcohol-induced hepatocyte injury is the WIF-B cell line. It has many hepatocyte-like features, including a differentiated, polarized phenotype resulting in formation of bile canaliculi. The aim of this study was to examine the effects of ethanol treatment on this cell line. WIF-B cells were cultured up to 96 h in the absence or presence...
Ethanol-induced neuro-developmental abnormalities are associated with impaired insulin and IGF signaling, and increased oxidative stress in CNS neurons. We examined the roles of ethanol and its principal toxic metabolite, acetaldehyde, as mediators of impaired insulin/IGF signaling and oxidative injury in immature cerebellar neurons. Cultures were exposed to 3.5mM acetaldehyde or 50mM ethanol ±...
Although alcoholism is a worldwide problem resulting in millions of deaths, only a small percentage of alcohol users become addicted. The specific neural substrates responsible for individual differences in vulnerability to alcohol addiction are not known. In this study, we used rodent models to study behavioral and synaptic correlates related to individual differences in the development of eth...
BACKGROUND Hyperhomocysteinemia plays an important role in the development of hepatic steatosis, and studies indicate that homocysteine-lowering treatment inhibits the development of fatty liver. OBJECTIVE We evaluated the effects of L-serine on alcoholic fatty liver and homocysteine metabolism. METHODS In a binge ethanol study, male C57BL/6 mice were divided into 4 groups: control, ethanol...
The effectiveness of ethanol pretreatment on preventing calcification of glutaraldehyde-fixed porcine aortic bioprosthetic heart valve (BPHV) cusps was previously demonstrated, and the mechanism of action of ethanol was attributed in part to both lipid removal and a specific collagen conformational change. In the present work, the effect of ethanol pretreatment on BPHV aortic wall calcification...
The effect of buspirone, a drug with mainly 5-HT1A-agonist activity, on voluntary ethanol intake was tested in a rat model of alcoholism. In this model the treatment consists of an injection of ethanol (2.0 g/kg) or saline once a week, preceded by a 24 h choice between water and ethanol (10% w/v). This weekly injection of ethanol reduces voluntary ethanol intake in male rats. Maximal inhibition...
In this study, the effects of ethanol and age on the morphology of the locus coeruleus (LC) and on the severity of ethanol-withdrawal symptoms were studied during a 5-week intermittent ethanol exposure. Young (3-4 months) and old (29-30 months) male Wistar rats were given highly intoxicating doses of ethanol by intragastric intubations for 4 days, followed by a 3-day ethanol-withdrawal period. ...
Ethyl glucuronide (EtG) is a direct ethanol biomarker and U.S. Department of Health and Human Services has advised that specificity studies at low EtG levels are needed for distinction of ethanol consumption and incidental exposure. The authors report urinary EtG excretion with ethanol abstinence, dermal exposure and oral consumption. EtG concentration by sensitive liquid chromatography-tandem ...
Alcohol drinking during adolescence is associated in adulthood with heavier alcohol drinking and an increased rate of alcohol dependence. Past research in our laboratory has indicated that peri-adolescent ethanol consumption can enhance the acquisition and reduce the rate of extinction of ethanol self-administration in adulthood. Caveats of the past research include reinforcer specificity, incr...
