Neonatal rats were exposed to 6.6 g/kg of alcohol each day between postnatal days 4 and 10 while artificial-rearing procedures were used, in a manner which produced high peak and low trough blood alcohol concentrations each day. Gastrostomy controls were reared artificially with maltose/dextrin isocalorically substituted for alcohol in the milk formula, and(More)
The effect of alcohol on body and brain growth of the neonatal rat was examined. An artificial rearing procedure was used to administer a milk formula containing 2.8% alcohol to rat pups during days 4-10 postpartum. Mean blood alcohol levels taken at hourly intervals between feelings at the end of the second day of exposure ranged between 151 and 163 mg/dl.(More)
Fetal alcohol syndrome (FAS) is now well documented, but factors that affect the severity of the accompanying central nervous system damage are still not well understood. In a series of experiments, artificially reared neonatal rats were exposed to alcohol during postnatal days 4-10 (during the brain growth spurt of the rat) to evaluate the consequences of(More)
To investigate whether or not blood alcohol concentration during the brain growth spurt has an influence on the permanency of alcohol-induced central nervous system damage, an artificial rearing technique was used to administer a daily dose of alcohol (6.6 g/kg/day) to neonatal rats during postnatal days 4 to 10. The alcohol was administered either in a(More)
Three separate groups of pregnant Sprague-Dawley rats were (1) fed a liquid diet containing 35% ethanol-derived calories, or (2) pair-fed this diet containing an isocaloric amount of maltose-dextrin instead of ethanol,or (3) fed laboratory chow ad libitum. Their offspring were killed after reaching at least 60 days of age, and their brains were processed(More)
Neonatal rats were exposed to alcohol during a period of brain development equivalent to part of the human third trimester. Rat pups were fed a milk formula containing either alcohol (9.8 g/kg/day) or isocaloric maltose/dextrin using artificial rearing techniques from postnatal days 4-10. Blood alcohol concentrations reached 345.8 +/- 15.6 mg/dl on(More)
Adult rats, exposed to ethanol in utero exhibit aberrant mossy fiber-like Timm staining in the distal infrapyramidal region of the hippocampus at midtemporal levels. The present study utilized the anterograde transport of HRP to verify that the aberrant pattern of Timm staining represented a terminal field of the dentate granule cells. One or more(More)
The increased proliferation of cancer cells is directly dependent on the increased activity of the endoplasmic reticulum (ER) machinery which is responsible for protein folding, assembly, and transport. In fact, it is so critical that perturbations in the endoplasmic reticulum can lead to apoptosis. This carefully regulated organelle represents a unique(More)
These data suggest the presence of peripheral opioid receptors that are involved in the clinical perception of pain. This is a radical change in our traditional thinking of opioid pharmacology and pain management. Most clinicians have been taught that opioids work through the central nervous system. These new data depart from this traditionally held view of(More)
