The correlation between cerebral glucose utilization and brain surface potassium concentration (BS-K+) was studied during reperfusion following bilateral cerebral ischemia in the gerbil. Cerebral glucose utilization rate was measured by the 14C-2-deoxyglucose method and BS-K+ was continuously monitored by a potassium sensitive membrane electrode. BS-K+ increased from 3.0 +/- 0.6 mM (mean +/- S....

The effect of potash biofertilizer and chemical fertilizer was studied on quantitative and qualitative traits of periwinkle in a factorial experiment based on a Randomized Complete Design with three replications, 48 experimental units, and two factors: (1) different methods of potash bio-fertilizer application at four levels of control (B0), seed inoculation (B1), root inoculation (B2) and seed...

1. ACTH administration (20 microgram day-1 kg-1) to sheep produces hypertension associated with a raised cardiac output and hypokalaemia. 2. The aim of the present experiments was to detail the haemodynamic changes associated with restoration of the extracellular potassium concentration in sheep with ACTH-induced hypertension. 3. After 7 days of ACTH treatment potassium chloride (10 mmol/h) was...

Astrocytes are critical regulators of neural and neurovascular network communication. Potassium transport is a central mechanism behind their many functions. Astrocytes encircle synapses with their distal processes, which express two potassium pumps (Na-K and NKCC) and an inward rectifying potassium channel (Kir), whereas the vessel-adjacent endfeet express Kir and BK potassium channels. We pro...

INTRODUCTION It is still controversial whether there are synergistic effects among different non-pharmacological interventions used in the treatment of hypertension. OBJECTIVES To evaluate the effect of aerobic exercise, oral supplementation of potassium and their combination on blood pressure, glucose metabolism, urinary albumin excretion and glomerular morphology in spontaneously hypertensi...

A new method for simultaneous mapping of cell topography and ion fluxes was developed. A highly sensitive ion sensor system was generated by coating atomic force microscopy tips with a PVC layer containing valinomycin, an ionophore for potassium. The activity of specific ions was traced on artificial ion-releasing PVC substrates. A boundary potential was generated owing to the selective exchang...

irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...

INTRODUCTION Anorexia nervosa is an eating disorder that continues to have a devastating impact on the lives of both adolescents and adults worldwide. We present a case of persistent chronic hypokalaemia in a patient with anorexia nervosa. CASE PRESENTATION A 26-year-old Caucasian woman was admitted to our eating disorders unit under Section 2 of Mental Health Act (1983) with a body mass inde...
