Time course of total and distrectual weight gain after refeeding in anorexia nervosa.

Anorectic patients who achieve complete recovery from the eating disorder can obtain a favorable psychosocial outcome but the long-term nutritional outcome is ill-defined. We investigated the time course of total and distrectual body composition during and after refeeding in 32 female patients with anorexia nervosa. Patients were enrolled at their lowest weight (T0) and re-examinated after a 15% weight gain (at a mean of 3 months, T1; n=17) and after 3 years of stable weight recovery (T2; n=8). At T2 patients were compared to a control group of 8 healthy females matched for age and body mass index. All subjects underwent dual X-ray absorptiometry and anthropometry at each visit. At T0, the 32 subjects were at 61%+/-8% of ideal body weight (IBW) with severe reductions in fat mass (FM; 7.1%+/-4.5%), fat free mass (FFM) and bone mineral content (BMC). At T2, the 8 subjects had gained 40% of initial weight, but remained at 85.1%+/-7.7% of IBW ( p<0.01 vs. controls), with a percent FM comparable to that of controls and an absolute FFM still deficient. BMC did not improve at T2 and remained 79% of that in controls. FM depletion was more severe in the limbs than in the trunk and at T2 the trunk/limb FM ratio remained greater than that in controls. These data strongly suggest that continued nutritional surveillance and support is necessary throughout these patients' lives, even after correction of the psychiatric illness and of severe underweight.

Ethyl alcohol induced skin temperature changes evaluated by thermography. Preliminary results.

The authors have investigated the validity of thermography in the study of ethyl alcohol induced hand blood flow changes in normal subjects before and after a standard meal. The superficial temperature changes of the hand of ten healthy subjects, 7 males and 3 females, 25-40 years old, were recorded in 4 conditions: a) on an empty stomach, b) after ingestion of a standard dose of ethyl alcohol (25 cc of whisky at 40%, corresponding to 10 g of alcohol), c) after a standard meal (1200 Kcal), d) after a standard meal and a standard dose of alcohol. Three male subjects were not drinkers. Arterial blood pressure and ECG were monitored during the different phases of the experiment. Results show a typical time course of the hand temperature in response to intake of alcohol, stronger in fasting non drinkers subjects. Our results confirm the valuable role of thermography in the study of alcohol-induced calorigenic effects.

Some blood parameters of water buffalo in different physiological conditions.

The Authors have studied the changes of GOT, GPT, ALP, CPK and Se in buffaloes under different physiological conditions (age, diet, different pre and post partum times). 99 adult buffaloes were classified in 8 groups on the basis of different pre, post partum time intervals. Moreover, other 39 animals were divided into 4 groups: A = 60-90 day old animals, fed with reconstituted milk supplemented with Vit E; B = same age, fed with maternal milk; C = 6-8 month old animals; D = 12-18 month old animals. In the various classes of animals blood ALP, GPT, GOT, CPK and Se were monitored. Results showed that the high variability in blood activity of the studied enzymes suggest that in establishing their reference values the physiological condition of the subject and the time interval from the parturition must be taken into account. The fact that Se was not detectable in many pregnant animals suggests that the prevention of myodistrophy in buffalo calves must be effected in prenatal epoch.
