CHURCHILL, T.A., and STOREY, K.B. 1994. Metabolic responses to dehydration by liver of the wood frog, Rana sylvatica. Can. J. Zool. 72: 14201425. The metabolic responses by the liver to the evaporative loss of up to 60% of total body water were quantified in spring-collected wood frogs, Rana sylvatic*~, a freeze-tolerant species. Dehydration stimulated rapid hyperglycemia, liver glucose levels ...

Resurrection plants can tolerate extreme water loss. Substantial sugar accumulation is a phenomenon in resurrection plants during dehydration. Sugars have been identified as one important factor contributing to desiccation tolerance. Phylogenetic diversity of resurrection plants reflects the diversity of sugar metabolism in response to dehydration. Sugars, which accumulate during dehydration, h...

OBJECTIVE To investigate the effect of dehydration time on tooth colour measurement in vitro using colourimetry. METHODS Ten extracted human maxillary central incisors were used. L*a*b* values at the centre of the labial surface of each tooth were measured using a colourimeter. The first measurement was performed after removal of excess water. The second and third measurements were performed ...

To identify the factors related to dehydration from diarrhoea, a hospital-based case-control study was carried out among under-2-year-old Bangladeshi children. The study compared 80 cases who had 'some' or severe dehydration with 160 age-matched controls who had 'no signs' of dehydration. All the cases and controls were examined and the mothers were interviewed in the hospital and followed at h...

BACKGROUND/OBJECTIVE Fluid, electrolytes and acid base disturbances are responsible for most deaths due to acute diarrhoea. The aim of this study is to describe the point-of-admission serum electrolyte profile of children with dehydration due to acute diarrhoea. METHODS In this cross-sectional study, the serum electrolyte levels of 185 children with dehydration due to acute diarrhoea were ass...

Our objectives were to compare the levels of circulating electrolytes, hormones, and renal function during 20 days of dehydration in camels versus the level in non-dehydrated camels and to record the effect of blocking angiotensin II AT1 receptors with losartan during dehydration. Dehydration induced significant increments in serum sodium, creatinine, urea, a substantial fall in body weight, an...

The present study assessed the effects of mild dehydration on cognitive performance and mood of young males. A total of twenty-six men (age 20·0 (sd 0·3) years) participated in three randomised, single-blind, repeated-measures trials: exercise-induced dehydration plus a diuretic (DD; 40 mg furosemide); exercise-induced dehydration plus placebo containing no diuretic (DN); exercise while maintai...

To investigate the predictive factors for dehydration in acute diarrheal patients, this case control study was conducted using the observational analytic method. Acute diarrheal patients who were admitted to the Hospital and Outpatient Pediatric Clinic, Dr Soetomo Hospital, were included in this study. By discriminant analysis, three significant variables were determined to differentiate dehydr...

AIM To systematically update diagnostic accuracy of the Clinical Dehydration Scale (CDS) in clinical recognition of dehydration in children with acute gastroenteritis. METHODS Six databases were searched for diagnostic accuracy studies in which population were children aged 1 to 36 months with acute gastroenteritis; index test was the CDS; and reference test was post-illness weight gain. RE...
