AIM To analyze the effects of premedication with Pronase for endoscopic ultrasound (EUS) examination of the stomach. METHODS This was a prospective, randomized and controlled clinical study. All patients were randomly assigned to either the Pronase group or placebo group. The pretreatment solution was a mixed solution of 20000 U of Pronase and 60 mL sodium bicarbonate solution in the Pronase ...

Microelectrode recordings from cells in rabbit ciliary epithelium have been made in vitro. Ionophoresis of Lucifer Yellow dye from microelectrodes during measurements of potential confirmed that the recordings were intracellular. Dye passed from the impaled cells into adjacent cells in both the nonpigmented and pigmented layers of the epithelium. Electrical coupling between epithelial cells als...

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...

The existing technologies for processing of pyrite cinder require improvement complex extraction non-ferrous, precious metals and iron. novelty the technology used in work cinders is preliminary chemical activation a solution sodium bicarbonate. optimal modes were determined according to temperature, duration, L:S ratio NaHCO3 concentration. It has been established that results changes phase co...

Soybean plants can grow by solely depending on fixed N2 through their root nodules, a symbiotic organ with rhizobia. In this study, when nodulated soybeans were cultivated using hydroponics and an N-free culture solution, the pH rapidly decreased to 4.0, which may be harmful for growth nutrient absorption. Therefore, we prepared new solution characterized less fluctuation due addition of potass...

Commonly used local anaesthetic (LA) solutions in the field of dentistry are acidic, and have been known to cause pain a burning sensation. The present study aimed determine pH levels commercially available LA with without adrenaline 8.4% sodium bicarbonate‑buffered solution, evaluate during administration buffered non‑buffered solutions. For this purpose, 20 patients deep dentinal carious lesi...

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...
