Analyses were made of myoglobin content of rat skeletal and cardiac muscle following continuous exposure to simulated altitudes of 18,000 feet for a 2–10-week period. About five dozen rats were used. Acclimatization was associated with an increase in the myoglobin concentration of thigh, diaphragm, gastrocnemius and heart muscles. Total myoglobin content, however, increased during acclimatization in cardiac muscle but not in the three skeletal muscles. This finding together with the body weight changes and muscle weight changes suggested that the increases in myoglobin concentration of skeletal muscle may be merely a reflection of a decreased water content of muscles.

Abstract Introduction Positive fluid status has been associated with a worse prognosis in intensive care unit (ICU) patients. Given the potential for errors in the calculation of fluid balance totals and the problem of accounting for indiscernible fluid losses, measurement of body weight change is an alternative non-invasive method commonly used for estimating body fluid status. The objective of the study is to compare the measurements of fluid balance and body weight changes over time and to assess their association with ICU mortality. Methods This prospective observational study was conducted in the 34-bed multidisciplinary ICU of a tertiary teaching hospital in southern Brazil. Adult patients were eligible if their expected length of stay was more than 48 hours, and if they were not receiving an oral diet. Clinical demographic data, daily and cumulative fluid balance with and without indiscernible water loss, and daily and total body weight changes were recorded. Agreement between daily fluid balance and body weight change, and between cumulative fluid balance and total body weight change were calculated. Results Cumulative fluid balance and total body weight change differed significantly among survivors and non survivors respectively, +2.53L versus +5.6L (p= 0.012) and -3.05kg vs -1.1kg (p= 0.008). The average daily difference between measured fluid balance and body weight was +0.864 L/kg with a wide interval: -3.156 to +4.885 L/kg, which remained so even after adjustment for indiscernible losses (mean bias: +0.288; limits of agreement between -3.876 and +4.452 L/kg). Areas under ROC curve for cumulative fluid balance, cumulative fluid balance with indiscernible losses and total body weight change were, respectively, 0.65, 0.56 and 0.65 (p= 0.14). Conclusion The results indicated the absence of correspondence between fluid balance and body weight change, with a more significant discrepancy between cumulative fluid balance and total body weight change. Both fluid balance and body weight changes were significantly different among survivors and non-survivors, but neither measurement discriminated ICU mortality.

The influence of previous nutrition on both the intake of herbage and the body weight changes of grazing sheep was examined in two field experiments. In the first experiment, herbage intake and weight changes were compared at different stocking rates (three, six, and nine sheep per acre). The second experiment was designed to examine the influence of previous undernutrition on the digestive capacity of sheep and on their rate of consumption of herbage in the field. As compared with previously better-fed sheep under similar grazing conditions, the previously undernourished animals showed a capacity to compensate for their nutritional handicap at all stocking rates. Within a short time they reduced the body weight advantage held by their better-fed mates to a non-significant margin. Compensatory growth was associated with a significantly (up to 20%) greater herbage intake by the undernourished animals, but this higher feed intake did not cause an increase in wool production. Undernutrition did not influence the apparent digestibility of a diet, but was associated with an increased rate of herbage consumption under field conditions.

SummaryThis paper describes the effect of three different growth rates on some offal components of Angus cattle. The growth rates were: high (H, 0·8 kg/day), low (L, 0·4 kg/day) and high-maintenance (HM, 0·8 kg/day followed by a period during which body weight was held constant).Equations are presented which enable the weights of the offal components to be calculated within the body weight range 300–440 kg.For most tissues, weights in the H group were greater than in the L and HM groups and included: liver, rumen-reticulum, small intestine and the total alimentary tract. Weight of fat trimmed from the rumen-reticulum, omasum, large intestine and total alimentary tract was also greater in the H than in the L and HM groups. The reverse situation held for head, feet and tail and the spleen.In spite of these differences between groups in weights and composition of offals, the carcass composition in all groups was similar (Murray, Tulloh & Winter, 1974). It appears that, at a given body weight, changes in the offals may buffer the carcass against change in composition when cattle are exposed to different growth patterns.

Background: Obesity is a growing problem so obesity is a threat to health, especially in a developing country like Indonesia. Obesity is a caused for death and burden of disease-causingvariousdiseases.Thisstudylookedatthecorrelationbetweenmental disorders associated with eating disorders or perceptions of changes in respondents’ weight toward depressive disorders. The perception to the body weight is one of the factors that are often found in symptoms of mental disorders. Objectives: This research aim to understand the individuals’ obesity condition picture of patients based on their characteristics. Methods: In this study individuals with depressive symptoms were established using MINI instruments through interviews using the ICD-10 Mini International Neuropsychiatric Interview Version mental health instrument conducted in October–November 2017 by nursing diploma enumerators who were trained by psychiatrists. The perception of the state of body weight obtained from sampling was carried out by stratified random sampling. This study is a further analysis of data on mentalhealthresearchconductedin3districts/citiesinIndonesia,namelyinthecityof Bogor,JombangandTojouna-Unadistrictsusingcrosssectionalmethod.Theresearch samplesanalyzedwereindividualswhoexperiencedsymptomsofdepression Results: From the 262 respondents who experienced a history of symptoms of depressive disorders, appetite disorders/changes in body weight experienced by majority of the respondents,amountingto66.0%.Asignificantrelationbetweengenderandownership economy level with the appetite disorder/body weight changes. Where women on lower economy level suffered from depression were highly probable risking appetite disorder/body weight changes experience. Conclusion: A majority of people with the depression symptoms history has the symptom of lack of appetite or the feel of the weight change. The symptom of lack of appetite/weight change happened to woman with depression and low income respondents.
