In fourth instar larvae of Camptochironomus tentans, net sodium uptake from 2 mM-NaCl has an electrogenic component. During net uptake the transepithelial potential (TEP) alters from a value of approximately - 40 mV (sign refers to haemolymph), in depleted animals, to approximately o mV. The TEP in depleted larvae is dependent upon external sodium concentration above about I mM-Na+, becoming in...

In isolated bundles of external intercostal muscle from normal goats and goats with hereditary myotonia the following were determined: concentrations and unidirectional fluxes of Na+, K+, and C-, extracellular volume, water content, fiber geometry, and core-conductor constants. No significant difference between the two groups of preparations was found with respect to distribution of fiber size,...

The importance of minerals in the diet of horses is well recognized by horse owners and equine nutritionists alike. The type and quantity of minerals required are very diverse and essential minerals include the major or macrominerals and the trace or microminerals. This discussion will be restricted to three macrominerals, sodium, potassium, and chloride (Na+, K+, Cl-), that are essential to th...

Distributions of dislocations in sodium chloride crystals, which were induced by heat treatment or working, were investigated, using a newly developed etchant. The crystals, which were annealed above 3 0 0 ° C , showed reduced dislocation densities and rearranged dislocation patterns. By raising the temperature to 600 ° C or 700 ° C many elongated subboundaries or subboundaries arranged in the ...

The dependence on ionic strength of protonation of glycine and its complexation with dioxouranium (VI) is reported in sodium perchlorate and sodium chloride solutions as background salts. The measurements have been performed at 25±0.1°C and various ionic strengths in the range 0.1 to 1.0 mol , using a combination of potentiometric and spectrophotometric techniques. The overall analysis  of the ...

This study assessed the selected properties of bread with reduced amount of sodium chloride. The bread was made from white and wholemeal wheat flour and rye flour. The dough was prepared using three techniques: with yeast, natural sourdough or starter sourdough. Sodium chloride was added to the dough at 0, 0.5, 1.0 and 1.5% of the flour mass. The following bread properties were examined in the ...

Urinary electrolytes are invaluable in the differential diagnosis and treatment of certain acid-base diseases. We have evaluated the accuracy and precision of three different automated chemistry analyzers and a chloridometer (Corning 925 Chloridometer, Hitachi 717 and 917 and Vitros 950) for chloride, sodium and potassium using standard solutions. Data indicate that the ISE modules on the Hitac...
