A 34 year old man, registered disabled as a result of muscle weakness, was admitted to hospital because of increasing weakness. He had profound hypokalaemia and admitted to taking up to 1400 ml of kaolin and morphine mixture daily. After considerable potassium replacement muscle power recovered completely. The hypokalaemia is likely to have been caused by the combination of liquorice extract an...

The large-conductance, calcium-activated BK-α/β4 potassium channel, localized to the intercalated cells of the distal nephron, mediates potassium secretion during high-potassium, alkaline diets. Here we determine whether BK-α/β4-mediated potassium transport is dependent on epithelial sodium channel (ENaC)-mediated sodium reabsorption. We maximized sodium-potassium exchange in the distal nephron...

background: potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. high serum potassium levels are thought to impair pulse conduction in purkinje fibers and ventricles more than that in the atrioventricular (av) ...

Acute hypoxia causes hyperventilation and respiratory alkalosis, often combined with increased diuresis, sodium-, potassiumand bicarbonate excretion. On a low sodium intake the excretion of the anion bicarbonate may be limited by the lower excretion rate of the cation sodium through activated sodium retaining mechanisms. This study investigates whether the short-term renal compensation of hypox...

The study examined the water supply situation in Abeokuta, with emphasis on quality of distributed by Ogun State Water Corporation from treatment plant Abeokuta Scheme. samples were collected standpipes (taps) across city randomly selected using stratified random sampling method and was analysed for physical chemical parameters: pH, total dissolved solids (TDS), electrical conductivity (EC), al...

INTRODUCTION The rapid decline in renal function caused by radiographic contrast agents usually is transient, but it can result in chronic kidney disease. The pathophysiology of contrast-induced nephropathy (CIN) is poorly understood, but it may include acute hypoxia-induced oxidative stress and free radicals generated within the acid environment of the renal medulla. Thus, the alkalization of ...

The province of Tandjile is one the 23 provinces Republic Chad. drinking water supply rate in this region remains low. Part population obtains its through open wells and / or surface water. Climatic anthropogenic variations recent years have shown how much groundwater can be influenced both terms quality quantity to used. objective study provide knowledge on state hydrodynamic hydrochemical par...
