Using 3 outbred dogs with pancreatic, gastric and jejunal fistulas, we examined changes in pancreatic exocrine secretion, duodenal pH and plasma CCK concentration after intragastric or intrajejunal administration of ethanol. Intragastric administration of 20% or 40% ethanol significantly lowered the pH in the duodenal cavity, and pancreatic fluid secretion and bicarbonate excretion were stimula...

Chronic and acute ethanol treatments increased the 3-hydroxybutyrate uptake by lactating rat mammary gland as a consequence of its high afferent concentration, without changing its relative extraction. The uptake of glucose was inhibited in the ethanol treated animals due to intrinsic alterations in the mammary gland metabolism as indicated by the decreased relative extraction and unchanged aff...

BACKGROUND Meconium fatty acid ethyl esters (FAEE) constitute a biomarker of heavy fetal ethanol exposure. Our objective was to measure meconium FAEE in fetal sheep following daily, relatively moderate-dose ethanol exposure in late gestation, and to evaluate their utility in identifying fetal organ-system injury. METHODS Pregnant ewes received ethanol (0.75 g/kg; n = 14) or saline (n = 8) via...

BACKGROUND The commercialization of second-generation bioethanol has not been realized due to several factors, including poor biomass utilization and high production cost. It is generally accepted that the most important parameters in reducing the production cost are the ethanol yield and the ethanol concentration in the fermentation broth. Agricultural residues contain large amounts of hemicel...

The influences of glucose concentration, initial medium acidity (pH), and temperature on the growth and ethanol production of Saccharomyces cerevisiae NK28, which was isolated from kiwi fruit, were examined in shake flask cultures. The optimal glucose concentration, initial medium pH, and temperature for ethanol production were 200 g/l, pH 6.0, and 35oC, respectively. Under this growth conditio...

A method for serial gas chromatographic determinations of acetaldehyde, acetone, and ethanol in alveolar air is described. The concentration of alcohol in alveolar air increased rapidly and then declined linearly following ingestion of ethanol, 0.5 ml/lb body weight, drunk as a 10% solution in 30 min. Acetaldehyde in alveolar air a t first increased rapidly to a maximum concentration, then decr...

OBJECTIVE To describe the successful treatment of accidental ethanol intoxication with hemodialysis in a dog. CASE SUMMARY A 1.5-year-old female intact mixed breed dog was presented in a comatose state believed to be due to ethanol intoxication. The initial 9 hours of supportive care treatment were complicated by multiple seizures and hypothermia, and resulted in only minimal improvement in t...

We investigate the retention force factor of sessile droplets pure (ethanol) and binary (water–ethanol) fluids laden with alumina nanoparticles placed on a critically inclined substrate. It is observed that while critical angle an ethanol droplet increases increase in concentration, for water–ethanol droplets, it reaches to plateau decreases slightly after 0.6 wt % nanoparticle loading. The eff...

AIMS In-vivo and in-vitro studies have shown that ethanol induces hepatocyte damage. The aim of the present study was to evaluate the effect of a broad range of ethanol concentrations on apoptosis and necrosis in primary culture of human and rat hepatocytes. METHODS Human and rat hepatocytes were isolated from human hepatectomies and male Wistar rats (200-250 g) using the classical collagenas...

BACKGROUND Alcohol consumption in pregnancy may result in serious adverse fetal outcome. Non- or low alcoholic wines and beers may be a risk-reduction strategy to help alcohol-dependent individuals to prevent or limit ethanol consumption. The objective of this study was to quantify ethanol concentrations in Canadian beverages claiming to contain no or low alcohol content. METHODS Forty-five d...
