OBJECTIVES To study hydration status in referees (main) and assistant referees (linesmen) during official football matches. METHODS Twelve male football referees were evaluated; all were volunteers. Before and after each match, the referee and one of the assistants were weighed without clothes and a blood sample was taken. Total water loss was determined for each subject from the change in bo...

In a combined radioactive isotope study, Nae, Ke, bromine space and total body water were measured in a group of fourteen hypothyroid subjects. These were compared with a 'control' group. Total body water and Nae were found to be increased in the hypothyroid subjects. In seven subjects, the measurements were repeated after treatment with thyroid hormone. Most of the subjects lost weight and sho...

Background Recent several observational studies have reported that high salt intake is associated with obesity. But it is unclear whether salt intake itself induce obesity or low salt diet can reduce body fat mass. We investigated whether a low salt diet can reduce body weight and fat amount. Matrials and Methods The randomized, open-label pilot trial was conducted at a single institution. A ...

BACKGROUND Early alterations in the cardiovascular structure and function may change normal body water distribution. The resulting fluid shifts may thus serve as an early marker for cardiovascular disease. However, studies examining this in healthy populations are absent. OBJECTIVE This study examined the association between the proportion of total body water that is extracellular water and s...

Background: The effects of aqueous extract of Fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in Wistar rats. Methods: In total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (A-E): animals in group A received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in gr...

The use of bioelectrical impedance analysis (BIA) is widespread both in healthy subjects and patients, but suffers from a lack of standardized method and quality control procedures. BIA allows the determination of the fat-free mass (FFM) and total body water (TBW) in subjects without significant fluid and electrolyte abnormalities, when using appropriate population, age or pathology-specific BI...

Knowledge of patient fluid distribution would be useful clinically. Both single-frequency (SF) and impedance modeling approaches are proposed. The high intercorrelation between body water compartments makes determining the best approach difficult. This study was conducted to evaluate the merits of an SF approach. Mathematical simulation was performed to determine the effect of tissue change on ...

Oedema and expansion of the extracellular fluid are well recognized as a complication of malnutrition in adults (McCance, 1951) as well as in children (Waterlow, Cravioto, and Stephen, 1960). An increase in total body water has also been described (Srikantia and Gopalan, 1957; Schnieden, Hendrickse, and Haigh, 1958; Smith, 1960). In the course of investigations on the renal function of malnouri...

Cuticular permeability (CP) values of worker and soldier castes of Coptotermes formosanus Shiraki and Coptotermes vastator Light were determined using gravimetric techniques. Comparisons were made between castes, species, and between colonies of C. formosanus and C. vastator. CP values did not differ among either species or colony, however they did differ between castes. Data reported here and ...
