Organic matter removal is accomplished rapidly and efficiently without removing carbonates by treating samples with a sodium hypochlorite solution. Quantities of organic matter left in samples by this treatment are commonly less than remain after hydrogen peroxide treatment of acidified samples. Stable suspensions result from the use of a sodium carbonate—sodium bicarbonate solution to wash and...

The mechanisms of the bicarbonate-induced decrease in the ocular standing potential (bicarbonate response) were investigated in the cat. An intravenous infusion of 1.4% sodium bicarbonate solution caused a decrease in the standing potential. A high-bicarbonate solution decreased or increased the potential across the retinal pigment epithelium-choroid tissue of the excised cat eye when applied b...

INTRODUCTION The incidence of contrast-induced nephropathy has increased simultaneously with the increase in contrast medium use in diagnostic and interventional procedures. The incidence of contrast-induced nephropathy in the general population is low, but increases exponentially in patients with risk factors, such as diabetes and chronic kidney disease. Several strategies have been used in or...

Forty patients with moderate degrees of dehydration and acidosis because of acute watery diarrhoea were successfully treated randomly with either WHO recommended oral rehydration solution containing 2.5 g sodium bicarbonate or an oral solution containing 2.94 g sodium citrate in place of sodium bicarbonate per litre of oral rehydration rehydration solution. Efficacies were compared by measuring...

in order to comprise the effects of sodium bicarbonate supplementation on anaerobic performance and some plasma metabolites, 16 young male athletes (age 20.58?3.25, height 175.33?2.48 cm and bmi 21.57? 2.68 kg/m2) participated in two 400 m running sessions one hour following sodium bicarbonate or placebo (calcium bicarbonate) supplementation with the counterbalanced order. there were three bloo...

During perfusion of a plasma-like solution, colonic absorption rate of chloride was much higher than the secretion rate of bicarbonate (34 vs. 3.5 meq/h, respectively). This might suggest that anion exchange (Cl/HCO3) accounts for only a small fraction of total chloride absorption. However, if the colon absorbs as well as secretes bicarbonate, this reasoning would underestimate the magnitude of...

this experiment was conducted using 216 male chicken (ross 308) to evaluate the effects of organic selenium and sodium bicarbonate supplementation on blood parameters, growth performance and carcass characteristics in heat stress condition. birds were reared under same condition and fed with similar diets till 28 d of age. at 28 days of old, broiler with similar weight were regrouped within die...

Uraemic acidosis was readily corrected by the infusion of sodium acetate solution, which gave comparable results to equivalent amounts of sodium bicarbonate infusion. Preliminary data suggest that this was true even in severe liver disease.

Erratum The original version of this article [1] unfortunately contained a mistake. The formula concentration described in the “Treatments” section was provided incorrectly. The corrected text is available below: “The SBCG1 treatment was a solution with sodium bicarbonate and calcium gluconate, both at a concentration of 0.75 % (w/v); and SBCG2 had the same concentration of sodium bicarbonate t...

The purpose of this study was to evaluate the effect of oral administration of sodium bicarbonate (300 mg·kg(-1) b.w.) on swim performance in competitive, (training experience of 6.6 ± 0.6 years) youth, (15.1 ± 0.6 years) male swimmers. The subjects completed a test trial, in a double blind fashion, on separate days, consisting of 4 x 50m front crawl swims with a 1(st) minute passive rest inter...
