Blood ethanol levels, caloric intake and weight gain were monitored over the 21-day gestational period in the gravid Sprague-Dawley rat as a function of the administration of ethanol in either a liquid diet (Ensure) or an aqueous saccharin solution. The mean daily percentage of ethanol consumed (38% vs 31%), and g/Kg of ethanol consumed (11.9 vs 9.7 g/Kg) were higher for the liquid diet group than the aqueous solution group. Ethanol consumption varied by the trimester in the Ensure but not in the saccharin solution rats. Proportional maternal weight gain, live litter size, and live litter weight did not vary as a function of the method of ethanol administration. Both groups exhibited significant diurnal periodicity in ethanol consumption, and the greatest caloric intake during the second trimester. The implications of these results for ethanol administration in gravid rats is discussed. 相似文献

BACKGROUND: Although thiopurines have a proven role in maintenance therapy for Crohn's disease, an alternative therapy is needed for patients intolerant or resistant to thiopurines. AIM: To evaluate the effectiveness of home enteral nutrition as a maintenance therapy regimen in which half of the daily calorie requirement is provided by an elemental diet and the remaining half by a free diet. We refer to this home enteral nutrition therapy as 'half elemental diet'. METHODS: Between 2002 and 2005, 51 patients in remission from two hospitals were randomly assigned to a half elemental diet group (n = 26) or a free diet group (n = 25). The primary outcome measure of this study was the occurrence of relapse over the 2-year period. RESULTS: The relapse rate in the half elemental diet group was significantly lower [34.6% vs. 64.0%; multivariate hazard ratio 0.40 (95% CI: 0.16-0.98)] than that in the free diet group after a mean follow-up of 11.9 months. Compliance was similar in the two groups. No adverse event occurred in any of the patients throughout the study. CONCLUSION: This randomized-controlled trial shows the effectiveness of an half elemental diet, which is a promising maintenance therapy for Crohn's disease patients. 相似文献

Background Acute gastrointestinal symptoms affect 90% of patients during pelvic radiotherapy. Elemental diet is protective in animal models. A nonrandomized study suggested benefit from a partial elemental diet. A pilot study suggested that radiotherapy patients only tolerate oral elemental diet comprising one-third of total calories for 3 weeks.
Aim To assess the feasibility and efficacy of replacing one-third of normal diet with elemental diet during the first 3 weeks of pelvic radiotherapy in reducing acute gastrointestinal toxicity.
Methods Patients were randomized to elemental diet or no intervention. Toxicity was assessed using the Inflammatory Bowel Disease Questionnaire, Vaizey Incontinence scale and Radiation Therapy Oncology Group tool. Faecal calprotectin measured intestinal mucosal inflammation.
Results Twenty-nine women and 21 men, median age 61.5 years were randomized. Patients taking elemental diet did not have lower gastrointestinal toxicity ratings or inflammatory markers ( P > 0.2). The mean dose taken was 21% (2–36%) of total caloric requirements.
Conclusions Patients cannot tolerate large volumes of oral elemental diet. The quantities consumed in this study produced no therapeutic benefit. Future studies should aim to replace a higher proportion of nutritional intake for a longer duration of radiotherapy treatment. 相似文献

Early postoperative feeding with elemental diet. 总被引:7,自引:0,他引:7
The value of early postoperative feeding with an elemental diet was assessed in 30 patients after major gastrointestinal operations. The patients were allocated at random to conventional treatment (control group) or feeding with the elemental diet (ED group). The clinical and metabolic course of the 15 patients in the ED group was significantly better than that of the controls. Patients in the ED group lost less weight and had a shorter stay in hospital. Negative nitrogen balance was more pronounced in the control group throughout the seven postoperative days. Energy intake was higher in the ED group. Provided elemental feeding is used with caution, it may be given from the first postoperative day. Patients do better metabolically and require shorter stays in hospital. 相似文献

One hundred and sixteen patients with acute remitting multiple sclerosis (MS) took part in a double-blind controlled trial of treatment with polyunsaturated fatty acids and were randomly allocated to one of four groups. Two groups received linoleic acid, one alone as a spread and one with gamma-linolenic acid in capsules (Naudicelle); and two control groups received oleic acid, one as a spread and one in capsules. Rates of clinical deterioration and frequencies of attacks were not significantly different between treated and control groups. Exacerbations were shorter and less severe in patients receiving a high dose of linoleic acid than in controls, but those receiving a lower dose--that is, Naudicelle--showed no such difference. Thus supplementing the diet with 20 g linoleic acid marginally affected the duration and severity of relapses of MS but had no effect on overall disability. The dose of Naudicelle used provided insufficient supplementation. 相似文献

Background : Elemental diet is considered an effective primary treatment for active Crohn's disease, but it is usually given by a feeding tube.
Methods : Twenty-two patients (12 males, median age 30 years, range 18–60) with moderately active Crohn's disease were enrolled in a randomized study in which the efficacy of an elemental diet administered orally was compared to high-dose corticosteroids in achieving clinical and laboratory remission. Ten patients were treated by oral elemental diet (Peptamen, Clintec, USA) and 10 received corticosteroids. Both treatment regimens lasted 2 weeks. The two groups did not differ with respect to age, sex, body weight, location of disease, treatment or disease activity prior to the study. In all patients studied, simple Crohn's disease activity index, nutritional status (expressed as body mass index), percentage of ideal body weight, fat mass, fat free mass, erythrocyte sedimentation rate, interleukin-6, intestinal permeability (expressed as permeability index), prealbumin, retinol binding protein and multiskin test were evaluated before and after treatment.
Results : After 2 weeks of treatment, there were significant improvements in simple Crohn's disease activity index, erythrocyte sedimentation rate, permeability index, body mass index, prealbumin, retinol binding protein and multiskin test in the elemental diet group. There were significant improvements in simple Crohn's disease activity index and fat free mass in the corticosteroid group.
Conclusions : These data suggest that, in the short term, an oral elemental diet is at least as effective as steroids in inducing remission of mild-moderately active Crohn's disease, but it may be more effective in improving the nutritional status of these patients, probably through a more rapid restoration of normal intestinal permeability. 相似文献

To better predict food effects on the bioavailability/bioequivalence of drugs and drug products from in-vitro data, a dissolution medium that simulates the initial composition of the postprandial stomach was developed. First, the physical parameters of two homogenized standard breakfasts often administered to assess food effects in pharmacokinetic studies were measured. These included pH, buffer capacity, osmolality, surface tension and viscosity. Subsequently, the match of the physical parameters of several commercially available liquid meals, including long-life milk, Ensure and Ensure Plus to those of the breakfasts was evaluated. Of the three liquid meals studied, Ensure Plus had the closest physicochemical behaviour to that of homogenized standard breakfasts. By increasing the viscosity of Ensure Plus with 0.45% pectin, it was possible to obtain a medium that closely resembles the FDA standard breakfast. 相似文献

To assess the hypolipemic and antiatherosclerotic activity of diprophyllinyl-4-benzyloxybenzoate guinea-pigs were kept on a high-lipid diet alone or with the tested compound for 21 days, and rabbits--for 3 months. It was found that diprophyllinyl-4-benzyloxybenzoate displays a distinct hypolipemic activity, particularly with respect to cholesterol, both in guinea-pigs and rabbits. It also depresses the cholesterol and the trigliceride content in liver homogenates and shows a tendency to normalize the low-density-lipoprotein fraction in guinea-pigs, as well as cholesterol of the high-density lipoprotein fraction, and malon dialdehyde in rabbits. The area of intima covered with atheromatous plaques was smaller in rabbits receiving the high-lipid diet with diprophyllinyl-4-benzyloxybenzoate than in those receiving that diet alone. 相似文献
