The sodium and chloride retaining effect of suprarenal cortical extracts and of crystalline compounds derived from the suprarenal cortex parallels their effectiveness in maintaining suprarenalectomized dogs. All of the active compounds thus far studied produce a potassium diuresis when injected into normal dogs. The injection of a synthetic compound, desoxy-corticosterone acetate, produced in n...

this study was conducted to find out the influence of in vitro salinity on growth parameters shoot length, number of leaves, number of new buds, the chlorophyll, chlorosis and necrosis and absorption of sodium, chloride, potassium, nitrogen and phosphorus of pear (pyrus communis cv. dargazi) in vitro propagated shoots. the experiment was conducted as a complete randomized design with 5 salinity...

STONER, L. C., M. B. BURG, AND J. ORLOFF. Ion transport in cortical collecting tubule; effect of amiloride. Am. J. Physiol. 227(2) : 453-459. 1974.-T b 1 u u es were dissected from rabbit kidneys and perfused in vitro. In cortical collecting tubules the transepithelial electrical potential difference (PD) was 35 mV (lumen negative). There was net active sodium reabsorption from the lumen and ne...

BACKGROUND Hypokalemia and paralysis may be due to a short-term shift of potassium into cells in hypokalemic periodic paralysis (HPP) or due to a large deficit of potassium in non-HPP. Failure to make a distinction between HPP and non-HPP may lead to improper management. Therefore, we evaluated the diagnostic value of spot urine tests in patients with hypokalemia and paralysis during 3 years. ...

The effects of i.v. and local anaesthetics on guineapig tracheal smooth muscle have been investigated in vitro. Diazepam, propanidid and ketamine induced relaxation and antagonized histamine-, acetylcholine-and potassium chloride-induced contractures in the tracheal smooth muscle. The relaxing effects of the anaesthetics were not affected by propranolol. Thiopentone, at concentrations which wou...

INTRODUCTION We have previously reported results of precipitation studies for neonatal parenteral nutrition solutions containing calcium chloride and sodium phosphate using visual methods to determine compatibility. The purpose of this study was to do further testing of compatibility for solutions containing calcium chloride using more sensitive methods. METHODS Solutions of Trophamine (Braun...

*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 ...

The sodium chloride cotransporter (NCC) has been identified as a key molecule regulating potassium balance. The mechanisms of NCC regulation during low extracellular potassium concentrations have been studied in vitro. These studies have shown that hyperpolarization increased chloride efflux, leading to the activation of chloride-sensitive with-no-lysine kinase (WNK) kinases and their downstrea...

BACKGROUND Patch testing is an essential procedure in the investigation of eczema in children. OBJECTIVES To analyse the frequency of contact hypersensitivity and allergic contact dermatitis among Polish children with eczema. PATIENTS/METHODS During an allergy screening programme involving 9320 children aged 7 and 16 years, 12.6% reported symptoms of chronic/recurrent eczema. From this grou...

1. Total body, intracellular, and extracellular electrolyte and acid-base changes were studied following sodium nitrate-induced potassium and chloride depletion and subsequent selective chloride repletion. 2. It was found that potassium and chloride depletion was associated with markedly decreased extracellular Na, K, CI and water content. Intracellular Na increased, intracellular K decreased a...
