This study evaluated the effect of VêO® premium (2 or 4)g and ascorbic acid on pregnant ewes some minerals. Twenty Iraqi are aged 2-4 years in Fallujah, Al-Anbar Government regions from August 5th, 2019, to February 9th, 2020. The were divided randomly into four groups. It was fed naturally one diet, (G1) given 4 g, (G2) 2 (G3) 40 mg, (G4) treated as control group. Blood samples taken monthly v...

Block of the delayed rectifier potassium current, IK, by the class IC antiarrhythmic agent, flecainide, and by the novel selective class III antiarrhythmic agent, E-4031, were compared in isolated cat ventricular myocytes using the single suction-pipette, voltage-clamp technique. Flecainide (10 microM) markedly reduced IK elicited on depolarization steps to plateau voltages (+10 mV) and nearly ...

BACKGROUND Animal experiments and epidemiological studies have suggested that high potassium intake may reduce the risk of stroke, but the evidence is inconclusive, and the role of other nutrients in potassium-rich foods remains unknown. METHODS AND RESULTS We examined the association of potassium and related nutrients with risk of stroke among 43 738 US men, 40 to 75 years old, without diagn...

We studied the effects of regular diet (0.35% NaCl/1.1% potassium), high sodium diet (4% NaCl/0.75% potassium), or high sodium and high potassium diet (4% NaCl/2.11% potassium) on blood pressure, plasma renin activity, renal and cerebrovascular lesions, and incidence of stroke and mortality in male stroke-prone spontaneously hypertensive rats (SHRSP). In the first 4 weeks, the rise in blood pre...

Cell motility was measured by the degree of the fluctuation of the light intensity which pass through optical microscope (X 150) observing systems. The photodiode was mounted on the eye-piece lense and its output was fed into the operational amplifier and finally connected to memory oscilloscope. The degree of cell motility was determined by the average amplitude of the intensity fluctuation ca...

To exploit the antiarrhythmic effect of amiodarone when patients develop the side effect of thyrotoxicosis three patients with hyperthyroidism induced by amiodarone were given simultaneously 1 g potassium perchlorate a day for 40 days and a starting dose of 40 mg methimazole a day while they continued to take amiodarone. As hyperthyroidism might have recurred after potassium perchlorate treatme...

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...

We studied the blood pressure, natriuretic, kaliuretic and humoral responses of 347 normal subjects after volume expansion and volume contraction to examine possible differences among whites, blacks and subjects of different ages. According to outpatient 24-hour urine collections, blacks excreted less sodium and potassium than whites. After similar states of sodium intake were achieved among al...

PURPOSE To test whether prostaglandin E2 (PGE2) is generated by cultured nonpigmented ciliary epithelial (NPE) cells treated with the phorbol ester, phorbol dibutyrate (PDBu), an activator of protein kinase C. In addition, the authors tested whether indomethacin, a cyclooxygenase inhibitor, influences the stimulation of active sodium-potassium transport observed in PDBu-treated cells. METHODS...

It has been suggested that renal involvement in leptospirosis appears to be a special form of acute renal failure characterized by a higher frequency of polyuria and the presence of hypokalemia with an elevated urinary fractional excretion of potassium [1]. The high frequency of hypokalemia is thought to be caused by a proximal or thick ascending limb of Henle tubular dysfunction [2, 3]. It has...
