1. Tallow (A) and rape oil (E) were obtained for evaluation. They were blended in the ratios A95:E5, A90:E10 and A80:E20. The three blends together with the two pure fats were each included at 40, 80 and 120 g/kg into a basal diet. 2. The experimental diets were evaluated for apparent metabolisable energy corrected to zero nitrogen retention (AMEN MJ/kg) and apparent fat availability (g/kg) using 6 replicates of a cage of two male broiler chicks 14 d old and 8 replicates of a cage of one Rhode Island cross cockerel approximately 1 year old. Diets were fed for 72 h then removed for 24 h. This was followed by a 48 h period when food was available ad libitum and a further 24 h of starvation. A total collection of excreta was undertaken each 24 h for the latter 72 h period. 3. Evaluation of AMEN and apparent fat availability for the individual fat blends was achieved through both linear and quadratic regression. 4. Synergism, as demonstrated by a higher determined than calculated AMEN value, was detected with fat blends fed to chicks but not cockerels and only at rates of inclusion beyond 80 g/kg. 5. No consistent differences between AMEN determined through calorimetry or AME determined with reference to apparent fat availability multiplied by fat gross energy were detected.

End-expiratory thoracic cavity volume (Vthx) was measured in eight volunteers lying supine by three-dimensional X-ray computed tomography using the Dynamic Spatial Reconstructor. Untrapped end-expiratory pulmonary gas volume at functional residual capacity (FRC) was determined by nitrogen clearance. Both measurements were done before and after induction of anesthesia-paralysis. After induction of anesthesia-paralysis, Vthx and FRC were consistently and significantly (P less than 0.01) reduced by 0.28 +/- 0.22 (SD) and 0.59 +/- 0.24 liter, respectively. The reduction of FRC was larger than the reduction of Vthx (delta Vthx) in six of the eight subjects, a finding suggesting that intrathoracic fluid (blood) plus trapped gas volume (Vtt) increased. Changes in Vthx were partitioned into volume changes from the thoracic rib cage (delta Vrc) and from shape and/or position changes of the diaphragm (delta Vdi). delta Vrc contributed significantly (0.17 +/- 0.15 liter, P less than 0.02) to delta Vthx, whereas delta Vdi contributed only in four of the eight subjects. We conclude that delta Vrc, delta Vdi, and delta Vtt contribute to the reduction of FRC after induction of anesthesia-paralysis in humans; the relative contribution of them varies among subjects.

Pathogen-free female Hartley guinea pigs were divided into four diet groups to determine optimal nitrogen requirements for growth, pregnancy and lactation. Three chemically defined test diets varying in total nitrogen were compared with commercial guinea pig feed. Within 13 days, 24 of 78 animals from the three test diet groups died or required euthanasia. Affected guinea pigs were depressed, lost weight and had distended abdomens. Distension, impaction and, in most cases, rupture of the spiral of the ascending colon and subsequent peritonitis were observed at necropsy. Husbandry changes which resulted in a decreased incidence of impactions included increased acclimatization time on commercial feed post-shipping, decreased animal density per cage and cessation of water medication with oxytetracycline.

Two hundred and forty individually caged Hubbard x Hubbard broiler breeders (BB) were fed one of six diets at 150 g/bird per day, which provided 19 or 25 g protein and 325, 385, or 450 kcal nitrogen-corrected metabolizable energy. In Trial 1, chicks hatched from 29-wk-old BB were sexed and 12 females and 12 males placed in each of four replicate floor pens per treatment. A 23% crude protein (CP) starter (0 to 20 day), 20% CP grower (21 to 34 day) and 18% CP finisher (35 to 41 day) diets were fed. Protein intake of BB had no effect on body weight of offspring. Energy intake of BB had no effect on growth of female offspring; however body weights of 20 day-old-male offspring were 575, 586, and 601 g for low, medium, and high energy intake, respectively (P less than or equal to .01). Increasing BB energy intake increased carcass protein and reduced fat in male offspring (P less than or equal to .01) and decreased the percentage of Canada Grade B ratings for both sexes (P less than or equal to .05). In Trials 2 to 4, chicks from BB at 32, 36, and 40 wk were sexed and cage-reared to 21 days of age. The energy intake of BB had no effect on female offspring growth. Male offspring weighed 570, 563, and 585 g for the low, medium, and high energy intakes, respectively (P less than or equal to .01).

To demonstrate that the anorexia and depletion of cachexia reverses on tumor removal, F344 rats underwent sarcoma resection when their food intake fell to 0 g/day. In survivors of surgery, reversal in food intake was apparent within 3 days postoperatively, followed after 2 days by gain in host weight. To detect whether the transmission of anorexia/cachexia in these tumor-bearing (TB) rats was via the circulation, four groups were studied: single non-tumor bearing (NTB); single TB; parabiotic NTB; and parabiotic TB. The measured blood exchange rate between parabiotic halves was 1.2-1.5%/min. No cachectic effect was detected in either half of the NTB parabionts. There was no evidence of sarcoma metastases in the tumor-free half of the parabiotic TB pair. All the rats associated with the presence of tumor showed cachectic effects but the degree and timing of effect varied among the three conditions, single TB, parabiotic TB half, and parabiotic tumor-free half. In all variables examined (fall in food intake, time of first fall in food intake, host weight loss, elevation of blood urea nitrogen) the severities were always in the same sequence: single TB greater than parabiotic TB half greater than parabiotic tumor-free half greater than NTB. In addition, the TB parabiotic pair had a significantly longer survival time and grew a significantly larger tumor than did the single TB animal. The parabiotic tumor had a slower initial growth rate and a slower deceleration rate than the singlet tumor. These results provide evidence for the humoral mediation of cancer-associated cachexia.

Functional residual capacity (FRC), rib cage and abdominal dimensions (rc-ab), central blood volume (CBV), and extra vascular lung water (EVLW) were measured in six lung-healthy subjects awake and during halothane anesthesia, muscle paralysis, and mechanical ventilation. FRC was assessed by multiple breath nitrogen washout, rc-ab dimensions by computerized tomography, and CBV and EVLW by a double-indicator dilution technique (thermo-dye). During anesthesia, FRC decreased by 0.5 1 (17%). The cross-sectional chest area was reduced by 12-20 cm2, causing an approximate reduction in thoracic volume by 0.3 1. Concomitantly, the diaphragm was moved cranially by an average of 1.9 cm, diminishing the thoracic volume a further 0.5 1. The abdominal cross-sectional area did not alter significantly, despite the shift of the diaphragm. CBV decreased by 0.3 1. EVLW did not change significantly. It is concluded that the thoracic volume is reduced during halothane anesthesia, muscle paralysis, and mechanical ventilation as a result of cranial shift of the diaphragm and reduction in transverse area. The decrease in thoracic volume is accompanied by a reduction in FRC and a displacement of blood from the thorax to the abdomen, the transverse area of the latter thus being maintained despite the shift of the diaphragm.

Previous studies have demonstrated that the anesthetic amine, chlorpromazine hydrochloride (CPZ), prevents cell necrosis in experimentally induced ischemic liver and heart disease and decreases the extent of galactosamine-induced cell death in the liver. The present model was designed to determine whether CPZ exerts a similar beneficial effect in kidney in a nephrotoxic model of acute renal failure in rats induced by the administration of mercuric chloride (2 mg/kg of body weight). The functional and structural changes in the kidney were evaluated and quantitated in animals pretreated with CPZ (40 mg/kg of body weight) or saline and then subjected to nephrotoxic injury. Compared to controls, the glomerular filtration rate was significantly lower (p less than 0.001) in saline- and CPZ-pretreated rats receiving mercuric chloride. Twenty-four hours after mercuric chloride administration the glomerular filtration rate was 446 +/- 38 microl/minute/gm of kidney weight, the fractional sodium excretion was 0.4 +/- 0.2%, and the urinary osmolality was 1440 +/- 193 mOsmoles/kg of H2O in the CPZ-treated animals compared to 26 +/- 18 microl/minute/gm of kidney weight (p less than 0.001), 10.1 +/- 9.8% (p less than 0.025), and 353 +/- 28 mOsmoles/kg of H2O (p less than 0.005), respectively, in the animals receiving mercuric chloride alone. The percentage of proximal tubule cell necrosis was 26.5 +/- 8.9% in the CPZ-pretreated group compared to 88.1 +/- 3.6% in the untreated group (p less than 0.001). Metabolic cage studies were performed to follow the time course of this model for 48, 72, and 96 hours after mercury injection. The serum creatinine values and fractional sodium excretions were significantly less in animals receiving CPZ compared to the untreated group at all time intervals examined. The serum urea nitrogen concentration and glomerular filtration rate were similar for the two groups after 48 hours, but the serum urea nitrogen level was significantly lower and the glomerular filtration rate higher after 72 and 96 hours in the animals pretreated with CPZ. In agreement with these findings were observations that animals pretreated with CPZ had significantly fewer necrotic cells 48 and 72 hours after mercury administration, and tubular regeneration appeared to be markedly accelerated. These results suggest that pretreatment with CPZ markedly lessens the degree of structural and functional impairment seen in mercuric chloride-induced acute renal failure in rats and increases the rate of recovery.

The effects of decaffeinated green tea on CBA mice have been contrasted with those of water during 3 to 5 months of exposure to various intensities of social stress. Intensity was modified by using different types of caging: Henry-Stephens complex population cages for maximum stress, open field population cages for intermediate levels, and siblings in standard mouse boxes for minimal stress. Two population densities were used: high, with 16 males and 16 females per population cage; and low, with approximately half this number. In three sets of experiments, 58 comparisons were made between body weight, blood pressure, pulse rate, scarring, blood urea nitrogen (BUN), adrenal and heart weights, plasma corticosterone, adult male mortality, and number of weanlings of those on decaffeinated green tea and matched groups on water. Twenty-five of the comparisons indicated less arousal with the decaffeinated green tea and in none was the water favored. Blood pressure fell from 150 to 133 mm Hg. These results support the proposal that the polyphenols (bioflavonoids) of tea may have a beneficial sedative action.

Halothane anesthesia administered to enzyme-induced animals in a hypoxic atmosphere consistently produced hepatic necrosis. Rats pretreated with phenobarbital were exposed to hypoxia at varying intervals after administration of halothane, enflurane, or isoflurane anesthesia. Anesthetics were administered at 1 MAC for 2 h. For each agent, hypoxia consisting of 8 per cent oxygen-balance nitrogen for 1 h was imposed at the end of anesthesia. In other groups of rats, we also used a 15-, 30-, 60-, and 120-min interval of 100 per cent oxygen between 2 h of halothane anesthesia and the imposition of hypoxia. Controls included enzyme-induced animals with and without hypoxia, hypoxia alone, and cage controls. Hepatic injury was graded by histologic examination of the livers. Injury was greater when hypoxia followed halothane anesthesia than when it followed enflurane, isoflurane, or enzyme-induction alone. A difference in injury score existed between control animals and those anesthetized with halothane who received a 15-min interval of oxygen before hypoxia. Combined results from the 15- and 30-min delay groups also were different from control. There was no difference between control and halothane groups when the oxygen interval was 60 or 120 min. The injury score of the enflurane and isoflurane groups were comparable to that of controls. We conclude that the potential for hypoxia-induced liver injury during recovery exists after halothane anesthesia. Neither enflurane nor isoflurane anesthesia produced significant hepatic injury in this model.

The investigation concerned the digestibility of nitrogen and the content of uric acid, ammonia, and urea in urine and feces in White Leghorn layers. Eight colostomized hens were given a commercial cage-layer diet. Feces and urine were collected under acid conditions. Acidified urine contained more ammonia than untreated urine. For quantitative determination of ammonia, Urine collection ought to be done under acid conditions. Of urinary nitrogen uric acid represented 88%, ammonia 7%, urea 3%, and 2% unidentified. Urinary ammonia constituted 90% of ammonia in total excreta and urinary urea 86% of the urea in excreta. By means of these distribution factors and content of nitrogen compounds in total excreta, good estimates of the nitrogen digestibility were obtained. Our method appears to be applicable to chickens of other ages, sex, breeds, and environmental conditions.
