Studies were undertaken to analyze the role of moisture content of foods in producing dietary obesity. Female CD rats consumed more energy when offered a sucrose solution and plain water to drink than when they were only given plain water, regardless of the sugar content of their diet (0-65%). This suggested that the overeating that commonly occurs when sucrose solutions are offered may not be due to sucrose per se. In subsequent experiments, rats were fed modified AIN-76 diets high in sucrose, starch or fat for 28-42 d. For some rats, the diet was liquefied by adding water to make a 32% suspension. Plain drinking water was always available. Rats fed high carbohydrate liquid diets, with or without solid diet, consumed 8-15% more energy than rats fed solid diet only. Rats fed liquid diets also gained 43-206% more weight than did rats fed solid diets. Analysis of carcass composition revealed that the liquid diets increased body fat. For high fat diets, the results were more complicated. Addition of water to a low cellulose, high fat diet did not increase adiposity, whereas addition of water to a high cellulose, high fat diet did increase adiposity. These results suggest that the obesity-inducing effects of feeding sugar solutions or cafeteria diets may be due, in part, to the high water content of these foods.

A 64-year-old man presented with mediastinal and bilateral hilar adenopathy, and a biopsy of a scalene node revealed non-Hodgkin's lymphoma. One week after a cycle of combination chemotherapy, he developed an esophagobronchial fistula. Following a resolution of pneumonia by antibiotics, a cervical esophagostomy was made and, after the improvement of his general condition with parenteral hyperalimentation, he was given one course of combination chemotherapy which was continued until the mediastinal lymph node shadow completely disappeared. A subcutaneous bypass operation was performed on the stomach. After receiving one more cycle of intensification chemotherapy, he was discharged. Three months later, a bronchoscopy showed healing of the fistula. Nine months postoperatively, there is no evidence of the lymphoma or the esophagobronchial fistula recurring. Esophageal involvement is rare in malignant lymphoma and this is only the sixth reported case of esophageal fistula of the respiratory tract in association with lymphoma, and just the second to be treated successfully.

Among the compromised physiological responses affected by aging is an impaired response to glucose. Since administration of 2-deoxy-D-glucose (2DG) produces both analgesic and hyperphagic responses in young adult rats, the present study examined whether systematic variations in these responses occurred as a function of age. Separate cohorts of 4, 9, 14, 19 and 24 month old female rats received ascending doses of 2DG (0, 50, 250, 450, 650 mg/kg) with tail-flick latencies and jump thresholds assessed 30, 60 and 120 min later. Then the same rats received 2DG injections (0, 650, 1200 mg/kg) and food intake was assessed 5 hr later. Significant decreases in 2DG analgesia were observed on the tail-flick test as a function of age with the maximal decrease observed at the highest 2DG dose. Significant decreases in 2DG analgesia were generally observed on the jump test as a function of age, although this effect was not as robust as that observed on the tail-flick test. Finally, significant and systematic decreases in 2DG hyperphagia were observed as a function of age following both the 650 mg/kg and the 1200 mg/kg doses. The observed decrements in the analgesic and hyperphagic responses to 2DG as a function of age appear to represent an orderly alteration in responses to glucoprivation through adulthood.

The effects of continuous intravenous (i.v.) or intraperitoneal (i.p.) infusion of regular insulin on food intake (FI) and body weight (BW) were examined. When rats were infused i.v. with insulin at 0.2 IU/h for 14 days, BW increased until the 10th day and then plateaued, whereas FI was augmented until the end of treatment. The 24-h hyperphagia was mainly due to a diurnal increase in FI--resulting mainly from a large augmentation in meal number, with unchanged meal size. Nocturnal meal number increased and meal size decreased so that nocturnal FI was not affected. At the cessation of infusion, rats became hypophagic and lost weight. Another group of animals, infused with a lower dose (0.1 IU/h), showed that the increases in BW and FI were dose-dependent. Insulin infused (0.2 IU/h) for 14 days via an i.p. catheter increased FI and BW. The 24-h increase in FI was again mainly due to an enhanced diurnal intake, but at the cessation of insulin infusion rats did not lose BW. In rats infused with insulin at 0.1 IU/h for 14 days, BW and FI did not increase. In rats infused via an implanted minipump with insulin at 0.1 IU/h for 7 days, however, BW increased significantly over controls for the first 3 days, without any significant change in FI, the discrepancy between results observed here and other results is discussed, these effects suggest a relative ineffectiveness of the i.p. route compared to i.v.

In a rabbit model, a variety of hyperalimentation solutions have been shown to have an adverse effect on the right atrium, pulmonary artery and pulmonary parenchyma when infused for one week into the right atrium. High concentrations of dextrose combined with amino acids produced the greatest morbidity and mortality. No clear relation exists between pH or osmolarity and toxicity. The pulmonary injury seen in this model may explain the occasional development of pulmonary hypertension in patients receiving long term total parenteral nutrition.

Secretory IgA (S-IgA), an immunoglobulin present in secretions, prevents the adherence of bacteria to mucosal cells and is the principle component of the gut mucosal defense system. The purpose of this study was to determine whether the route of nutrient administration affects S-IgA. Twenty-five female Fisher rats were randomized into three groups. Groups I and II were fed an isonitrogenous, isocaloric standard hyperalimentation solution, Group I intravenously and Group II via a gastrostomy. Group III (control) was fed rat chow and water ad lib. Since bile is one of the principle sources of S-IgA, animals had biliary T-tubes placed for sampling of bile every 4 days. At day 16, Group I animals were fed rat chow and water for an additional 8 days. S-IgA was measured by the ELISA immunoassay. Results indicated at day 16 that the S-IgA level in mg/ml of Group I was 1.1 +/- 0.2, while the S-IgA in Groups II and III was 2.2 +/- 0.6 and 2.2 +/- 0.26, respectively. Furthermore, the S-IgA level in Group I after 8 days of enteral feeding rose to 1.8 +/- 0.4. The difference in S-IgA levels between enterally and parenterally fed rats suggests that an important defense barrier is compromised during parenteral hyperalimentation. Rats fed the same nutrients by gastrostomy maintained S-IgA levels better than rats fed the same nutrients intravenously. The rapid return to normal levels after resumption of enteral feeding suggests that the intraluminal presence of foodstuffs is essential for maintenance of S-IgA.

A 1-day-old male infant with congenital short small bowel was transferred to our hospital because of bilious vomiting and abdominal distension. An exploratory laparotomy performed at the age of 8 days revealed malrotation without any volvulus or stenosis of the small intestine, which was 45 cm long. There were no other anomalies except absence of the appendix. Postoperative nutritional support was by intravenous hyperalimentation and administration of elemental diet. However, parenteral nutrition was discontinued because of hyperbilirubinaemia. The patient died from marked emaciation at 2 months of age despite the administration of elemental diet. Therefore, careful total parenteral nutrition is the only management for successful therapy until the child's intestinal absorptive function develops.

The effects of opioid antagonists on seasonal changes in feeding behavior of white-tailed deer (Odocoileus virginianus) during fall, winter, and summer, as well as in bottle-fed fawns are described. Naltrexone had no effect on the amount of milk ingested by bottle-fed fawns. After weaning naltrexone significantly decreased feeding in both the summer and winter, with no difference in the effect for either season, indicating that opioids do not play a role in the winter hypophagia or the summer hyperphagia in deer. Similarly there was no seasonal effect on the ability of naloxone to decrease feeding in yearlings during summer, fall, and winter. Naltrexone significantly decreased spontaneous locomotion in the fawns in winter and the fall. In yearlings there was a tendency for the high dose of naloxone to decrease spontaneous locomotion in winter whereas in summer and fall it tended to enhance time spent moving. These data suggest that the endogenous opioid control of feeding in deer is independent of the seasonal effect on feeding and endogenous opioids do not play a role in the seasonal rhythmicity of feeding in deer. The effects of endogenous opioids on spontaneous locomotion do appear to be linked to changes in seasonal activity patterns.

Certain "primitive" peoples such as traditional-living nomadic Eskimos have as yet been spared from the current epidemic of ischemic heart disease. A review of risk factors for underdeveloped populations suggests that environment rather than constitution is responsible. Favourable factors include the absence of overeating, a substantial level of of physical activity, only recent acquisition of the cigarette habit and absence of competitiveness. However, risk factors generally operate as in the "white" community, and where a Western lifestyle is embraced through either migration or acculturation the prevalence of ischemic heart disease rapidly increases to the levels encountered in "civilized" groups.

A highly palatable diet (cafeteria diet) provokes an hyperphagia. The effects of Mu and Kappa opiate antagonists (Mu : Naltrexone 0.5 mg/Kg IP; Kappa Mr2266 0.5; 2.5; 10) and agonists (Mu Morphine 0.05; 0.1; 0.5; 2.5; Kappa Mr2033 0.5; 2.5) were studied on the nocturnal food intake of cafeteria rats and chow rats fed with monotonous food. At low doses Mu as well as Kappa antagonists do not modify the food intake of chow rats, but suppress the hyperphagia induced by the cafeteria diet. Kappa agonist provokes a decrease in food intake in chow and cafeteria rats while the Mu agonist at low doses suppresses the hyperphagia induced by cafeteria diet. The involvement of these two opioid systems in this type of hyperphagia is discussed.
