摘要:: The specific role of nutritional status during gestation in exacerbating or mitigating fetal toxicity of ethanol (EtOH) remains unclear. We used an intragastric infusion model (Total enteral nutrition, TEN) to appropriately control for dietary EtOH consumption and caloric intake. Time impregnated female Sprague Dawley rats (250-300 g) were surgically cannulated with intragastric cannulae (on gestation day 4) and infused either control or EtOH-containing diets. Rats were fed 220 kcal/ kg3/4/d (NRC recommended caloric intake for gestation) or 160 kcal/ kg3/4/d (undernourished to 72% of control) diets containing either 12 g/kg/d EtOH or an isocaloric amount of carbohydrates from gestation days 6-15. Maternal hepatic gene expression profiles were assessed on GD15. The present data dissect specific effects of nutritional status during gestation and EtOH intake and the interaction thereof. The data reveal a highly significant interaction between undernutrition and EtOH consumption. Experiment Overall Design: Four groups of time impregnated female Sprague Dawley rats were utilized. Experiment Overall Design: Group 1: Control, TEN-220, control group fed normal (non-EtOH containing) diets at 220 kcal/ kg3/4/d. Experiment Overall Design: Group 2: Ethanol-220, EtOH-220 (EtOH group fed EtOH containing diets) at 12 g EtOH/kg/d diets at 220 kcal/ kg3/4/d. Experiment Overall Design: Group 3: Control-160, TEN-160, (undernourished control group fed normal (non-EtOH containing) diets at 160 kcal/ kg3/4/d. Experiment Overall Design: Group 4: Ethanol-160, EtOH-160, (undernourished rats fed EtOH containing diets) at 12 g EtOH/kg/d diets at 160 kcal/ kg3/4/d
