BACKGROUND Previous studies have demonstrated individual differences in susceptibility to the detrimental effects of prenatal ethanol exposure. Many factors, including genetic differences, have been shown to play a role in susceptibility and resistance, but few studies have investigated the range of genetic variation in rodent models. METHODS We examined(More)
Research has shown variations in susceptibility to alcohol-related birth defects in humans. Genetic differences are one reason for this variability. This study compared three inbred mouse strains to determine whether they differ in their susceptibilities to ethanol teratogenesis because previous studies have generated conflicting data. Pregnant C57BL/6J(More)
Both maternal and fetal genetic factors influence variations in response to prenatal ethanol exposure. To assess the effect of maternal genotype on the incidence of ethanol teratogenesis, a reciprocal cross study was conducted in an animal mode using the relatively susceptible C57BL/6J (B6) and the relatively resistant DBA/2J (D2) inbred mice. This mating(More)
Behavioral studies using mice have suggested circadian influences on response to ethanol. Studies examining possible circadian influences on ethanol elimination are ambiguous as to whether changes in elimination contribute to circadian variations in response. Therefore, the linear declines in blood alcohol concentrations (BACs) were assessed in long-sleep(More)
Genetic differences in susceptibility to fetal alcohol effects (FAE) have been suggested by both human and animal studies. The Long-Sleep (LS) and Short-Sleep (SS) mouse lines, selectively bred for differences in ethanol-induced narcosis, provide a model for studying differential alcohol sensitivity in the etiology of FAE. LS and SS mice were intubated with(More)
A quantitative, multidimensional animal model of the alcohol withdrawal syndrome is desirable for investigating individual differences in susceptibility to alcohol dependence. Following exposure to control or ethanol diets for 7 or 14 days, we measured respiration rates, body temperature, acoustic startle responses, and heart rates in Long-Sleep (LS) and(More)
Concentration-dependent effects of ethanol upon behavior and upon physiological regulatory mechanisms have been suggested. In a previous study, we found that the concentration of an acute ethanol injection confounded dose-response relationships for measures of blood pH, PCO2, and PO2. Two lines of mice that differ in CNS sensitivity to the hypnotic effects(More)
The effects of ethanol on blood pH, PCO2, and PO2 were measured in LS and SS mice in an attempt to ascertain whether these lines of mice, which differ in CNS sensitivity to the behavioral effects of ethanol, also differ in sensitivity to physiological effects of this drug. Long-sleep (LS) female mice were injected intraperitoneally with 1.8, 2.5, 3.3, or(More)
Alcohol sensitivity may influence the severity of alcohol-related birth defects (ARBD). To examine this hypothesis, pregnancy outcome and offspring development were examined in alcohol-sensitive Long-Sleep (LS) mice and alcohol-resistant Short-Sleep (SS) mice following prenatal ethanol exposure. Dams were intragastrically intubated twice per day (6 hr(More)
An animal model was used to see if maternal genetic factors contribute to ethanol-induced fetal malformations. Susceptible C57BL/6J (B6) and resistant Short-Sleep (SS) mice were used in a reciprocal cross-breeding design. This design produced four fetal genotypes: true-bred B6B6 and SSSS liters and hybrid B6SS and SSB6 litters. Dams were intubated with(More)
