1. DNA has been isolated from different mammalian tissues. The DNA preparations were free from RNA, protein and polysaccharides and have a similar range of sedimentation coefficients (approx. 24s). 2. Protein was removed by a two-stage extraction with a phenol-cresol mixture by using a detergent with 4-aminosalicylate in the first stage and sodium chloride in the second. 3. Polysaccharides rema...

Sodium and chloride are essential for numerous processes in the body including the regulation of osmotic pressure and acid-base balance. Both sodium and chloride also play important roles in the digestion and absorption of several nutrients from the gastrointestinal tract. Absorption of glucose and most amino acids from the small intestine requires an adequate supply of sodium. In cattle, magne...

We determined the sodium pump activity, measured as ouabain-sensitive 86Rb+ uptake, in the tail arteries of rats treated with deoxycorticosterone and sodium chloride for 6, 9, 14, 28, and 50 days. Systolic blood pressures, plasma sodium, potassium, and creatinine concentrations were measured, and the body weights were recorded. Vascular sodium pump activity was suppressed (by 27%) at the 6th da...

There have been many investigations on non-biodegradable materials acting as an antibiotic carrier for local drug delivery systems based on polymethyl methacrylate (PMMA) beads. However, the material is non-degradable and non-porous so that less than 5% of the encapsulated drug is released. In order to obtain better release of the antibiotics, greater porosity of the beads would be required. Ad...

BACKGROUND To assess the quality of sweat test (ST) based on the proportion of sweat sodium and sweat chloride as diagnostic parameter of cystic fibrosis (CF). METHODS A retrospective study of 5,721 sweat samples and subsequent descriptive analysis were carried out. The test was considered "of good quality" (correct) when: (i) sweat chloride was lower than 60 mEq/L, and sweat sodium was highe...

T HAT most hypertensive patients excrete more water, sodium, and chloride than do normotensive patients when given sodium chloride has been well established since the studies of Farnsworth and Barker.1-3 They pointed out that during diuresis a higher percentage of filtered chloride is excreted by hypertensive individuals. Green, Wedell, Wald, and Learned4 found water and sodium excretion to be ...

An investigation of small intestinal electrolyte transport was performed in a subject with congenital chloridorrhoea using a constant perfusion technique. The results indicate that the diarrhoea was not due to an abnormally high rate of secretion of fluid into the duodenum, and transport of electrolytes and glucose was normal in the jejunum. In contrast there was a marked abnormality of electro...

*Corresponding author: [email protected] ___________________________________________________________________________ This research was carried out to determine the effect of supplementation of sodium bicarbonate (% 0.38, % 1.5), potassium chloride (% 0.7) and sodium chloride (% 0.25) at different levels in diets of 480, 25-week old laying hens on blood plasma Ca, Pi, Mg, CI, Na, K, total ...

This research examined the effect of chemical factors (pH, sodium chloride, sugars (glucose and sucrose), preservatives (benzoic acid and sorbic acid)) and clove oil to decrease the growth of film yeasts (Saccharomyces cerevisiae J1, Candida krusei J2 and Candida krusei J3) on fermented bamboo shoots. All yeasts grew at pH 3.0-7.0 and did not grow greater than 7.5%(w/v) of sodium chloride conce...
