The suppressive effect of sodium and calcium salts applied individually or combined with the yeast Saccharomyces cerevisiae against Alternaria solani the causal agent of early blight disease of potato was evaluated under laboratory, greenhouse and field conditions. In vitro test a complete inhibition in fungal growth was observed at concentration of 30 mg/ml of both sodium bicarbonate and calci...

Darrow and his associates (1, 2) have recently obtained evidence that a correlation exists between the concentration of serum bicarbonate, muscle potassium, and intracellular sodium from a study on rats subjected to procedures designed to produce a deficit of one of the ions sodium, chloride, or potassium. Thus, the serum bicarbonate concentration was found to vary directly with the intracellul...

Whole gut perfusion in humans was used to compare the effect on intestinal water and electrolyte transport of the World Health Organisation oral rehydration solution (solution II, composition in mmol/l: glucose 111, sodium 90, bicarbonate 30, potassium 20; 308 mOsm/kg); a hypertonic commercial oral rehydration solution (solution III, glucose 188, sodium 50, bicarbonate 20, potassium 20 mmol/l; ...

A 28-year-old female with history of hypothyroidism, Sjögren's Syndrome, and Systemic Lupus Erythematosus (SLE) presented with complaints of severe generalized weakness, muscle pain, nausea, vomiting, and anorexia. Physical examination was unremarkable. Laboratory test showed hypokalemia at 1.6 mmol/l, nonanion metabolic acidosis with HCO3 of 11 mmol/l, random urine pH of 7.0, and urine anion g...

This study has examined the acute haemodynamic effects of 7% sodium bicarbonate solution 1 mmol kg-1 (1.2 ml kg-1) administered into the right atrium over 5 s in 25 anaesthetized dogs allocated randomly to respiratory (arterial pH (pHa) 7.18, PaCO2 10.1 kPa (n = 8)) or metabolic acidosis (pHa 7.27, base deficit -9.0 mmol litre-1 (n = 7)) or metabolic neutrality (pHa 7.39 (n = 10)). The pHa and ...

Simultaneous perfusion of peritubular capillaries and proximal convoluted tubules was used to study the effect of varying transepithelial ionic gradients on ionic fluxes. Results show that net sodium influx and volume flux was one-third of normal when bicarbonate was absent, no chloride gradient existed, and glucose and amino acids were absent. Addition of bicarbonate to the luminal fluid did n...

Introduction From the point of view of different technological processes, the knowledge of parameters describing the structure of sorbents, such as surface area or pore size distribution play an important role for application them in chemical, cement industries, or modification of mineral raw materials. The sorption properties are determined by surface area, what binds with surface energy and r...

This study investigated the effects of creatine and sodium bicarbonate coingestion on mechanical power during repeated sprints. Nine well-trained men (age = 21.6 ± 0.9 yr, stature = 1.82 ± 0.05 m, body mass = 80.1 ±12.8 kg) participated in a double-blind, placebo-controlled, counterbalanced, crossover study using six 10-s repeated Wingate tests. Participants ingested either a placebo (0.5 g·kg(...

BACKGROUND AND OBJECTIVES Sodium bicarbonate has been proposed for protection of the kidney from contrast-induced AKI (CIAKI). However, the effects of bicarbonate on long-term important clinical outcomes are uncertain. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In a prospective, double-blind, multicenter randomized clinical trial, 391 patients with an eGFR<45 ml/min per 1.73 m(2) undergoin...

BACKGROUND Contrast-induced nephropathy is the leading cause of in-hospital acute renal failure. This side effect of contrast agents leads to increased morbidity, mortality, and health costs. Ensuring adequate hydration prior to contrast exposure is highly effective at preventing this complication, although the optimal hydration strategy to prevent contrast-induced nephropathy still remains an ...
