Abstract:
Young Awassi sheep were subjected to 5-d periods of complete water restriction in metabolic cages. During water deprivation there were steady declines in food intake and faeces and urine excretion. The blood haematocrit and urine and plasma osmolalities increased. There was a decline in blood and faecal water. As dehydration progressed, urinary excretion of osmotically active substances was greatly reduced. When drinking water was presented following 5 d of restriction it took 24 h to replace water losses and for urine to be excreted. Faecal water did not return to normal within 24 h. The shee

Abstract:
Samples of maternal and fetal plasma, fetal urine, and amniotic fluid were collected from 8 chronically cannulated pregnant llamas, in the last third of gestation. The samples were obtained for up to 18 days post-surgery. Osmolality, sodium (Na), potassium (K), chloride (Cl), and urea were measured on 40 samples collected on days 1, 2, 3, 4-5, 6-7, 8-9, and 10-19. The osmolalities of maternal and fetal plasma, fetal urine and amniotic fluid, averaged over these 7 time periods, were, respectively, 312 +/- 2, 311 +/- 1, 484 +/- 14, and 317 +/- 1 mosmol kg-1.

BACKGROUND. Nephrotic syndrome (NS) develops with severe damage to the glomerular filter. The kidneys play a key role in the regulation of water-electrolyte homeostasis. However, the features of water-electrolyte disorders in glomerulopathy have not been studied enough. The aim of our study was to determine the main indicators of renal electrolyte transport in adult patients with NS. PATIENTS AND METHODS. 173 patients with glomerulopathy, 114 men and 81 women, were examined. The average age is 39.0±15.8 years. All of them were hospitalized during 2016-2019 years.

SUMMARY Endogenous creatinine clearance and renal excretion of phenylbutazone, osmotically active material, and compounds contributing to the urinary refractive index were studied in 12 Thoroughbred mares after no treatment, after water administration, or after furosemide administration. Urine was quantitatively collected, using urinary bladder catheters. On average, urine flow of the mares was 9 μl/min/kg without treatment and increased to about 50 μl/min/kg after water administration and to about 70 μl/min/kg after furosemide administration.

The main non-ionic osmotically active substances in blood serum are glucose and urea. The aim of the study was to study the changes in the water-osmotic state caused by non-ionic (organic) substances in patients with delirium tremens (DT) and in a state of alcohol withdrawal, and to assess their influence on the blood leukocyte composition and the clinical manifestations of the disease. A total of 747 men were examined in a state of alcohol withdrawal; of these, 450 people had manifestations of severe DT (F10.43), 213 — “classic” DT (F10.4), 84 patients had signs of alcohol withdrawal with som

On the basis of the developed physical and mathematical model of mass transfer, which takes into account the transmembrane transfer of non-electrolytes, basic ions and the associated changes in the transmembrane potential, the redistribution of osmotically active substances during equilibration of erythrocytes in cryoprotective solutions was investigated. Time parameters of changes in concentrations of osmotically active substances inside and outside cells, as well as transmembrane electric potential, were calculated.

Abstract:
Metabolism consists of the sum of anabolism (construction) and catabolism (destruction) with the release of energy, and achieving a fairly constant internal environment (homeostasis). The aquatic external environment favours differences from mammalian pathways of excretion and requires osmoregulatory adjustments for fresh water and seawater though some taxa, notably marine elasmobranchs, avoid osmoregulatory problems by retaining osmotically active substances such as urea, and molecules protecting tissues from urea damage. Ion regulation may occur through chloride cells of the gills. Most fish

Abstract:
The normal range for serum sodium levels in most laboratories is 135–145 mmol/l. Hyponatraemia is defined as a serum sodium concentration of &lt;135 mmol/l (&lt;120 mmol/l is severe), and hypernatraemia as a concentration &gt;145 mmol/l. As sodium is the major extracellular electrolyte, and freely diffuses throughout the extracellular space, it plays a key role in regulating osmolarity. Hyponatraemia is almost always associated with a hyposmolar state, except for the rare circumstances when there are other osmotically active substances present at high levels (e.g. glucose).

AbstractPer- and poly-fluoroalkyl substances are a group of synthetic aliphatic compounds containing one or more perfluoroalkyl moieties (CnF2n + 1-). Due to their unique surface-active properties and high chemical and thermal stability, they are used in various consumer products such as cosmetics, food packaging, furnishings, and textiles. Their use dates back to the 1940s. Despite their peculiar performances, recent scientific works investigate their sustainability and safety deriving from environmental ubiquity, persistence and bioaccumulation. Indeed, these chemicals are not metabolized in

Abstract:
The kidneys are responsible for maintaining the constant chemical composition of body fluids. This process begins with high-pressure filtration in specialized glomerular capillaries located in the renal cortex. The pressure filtration produces an ultrafiltrate of plasma made up of the water and smaller molecules. As the fluid passes along the renal tubules, water, electrolytes, and non-electrolytes are reabsorbed in the required amounts by a process of selective reabsorption. Some active secretion of unwanted substances also occurs. Following this reabsorption the remaining tubule fluid is pas
