PURPOSE The purpose of this study was to determine, on the animal model, the effect of modification of diet composition and administration of selected food additives on water balance in the body. MATERIAL AND METHODS The study was conducted with 48 males and 48 females (separately for each sex) of Wistar strain rats divided into four groups. For drinking, the animals from groups I and III wer...

Two facts must be taken into consideration when quantifying fibronectin in biological samples: the sensitivity of the assay method and the appropriate handling of samples. A three-antibody, non-competitive ELISA was used in the present study. This procedure offers a simple, inexpensive and very sensitive technique for evaluating fibronectin: reproducible standard curves in the range 5-100 micro...

Body weight and fluid input/output are usually monitored for checking fluid balance in case of intravenous hyperhydration during nephrotoxic chemotherapy. The reliability of measuring fluid input/output is uncertain. Moreover, this measurement is redundant, complex, labour-intensive and represents an occupational hazard for nurses and other health-care workers handling fluids or body excreta. I...

We performed intake, digestibility and ingesta passage studies in 11 Indian rhinoceroses (Rhinoceros unicornis) from four zoological institutions, using total faecal collection for the quantification of faecal output. The regularly fed zoo ration of roughage and concentrates (ration RC) and a roughage-only ration (ration R) were used; the roughage source differed between the facilities and comp...
