Dahl showed that feeding KCl prevents the rise in blood pressure caused by a high NaCl diet in salt-sensitive Dahl "S" rats. Such S rats when normotensive on a low NaCl diet have a 2 to 3 times greater pressor response than Dahl "R" rats to intracerebroventricular hypertonic saline (600 mOsm/liter) or angiotensin II (AII) (500 ng). Does dietary KCl prevent NaCl hypertension in S rats partly by ...

INTRODUCTION Even though dehydration could aggravate formation of urinary calculi, the effects of fluid and food restriction on calculus formation is not thoroughly defined. The purpose of this study is to evaluate the effects of fluid and food restriction in Ramadan fasting on urinary factors in kidney and urinary calculus formation. MATERIALS AND METHODS Fifty-seven men aged 30 to 55 years ...

Previous investigations have confirmed the potential effectiveness of various metabolic stimulants and physiological salt solutions in supporting broiler embryogenesis. The current study investigated the effects of the same solutions on chick posthatch performance and tissue nutrient profiles. In the first of 2 trials, 200 μL each of a (i) 0.18 mM carbohydrate electrolyte nutrient (CEN) solutio...

BACKGROUND Potassium citrate (K-Cit) is one of the medications widely used in patients with urolithiasis. However, in some cases with calcium oxalate (CaOx) urolithiasis, the significant response to alkaline therapy with K-Cit alone does not occur. There is scarce published data on the effect of magnesium chloride (Mg-Cl(2)) on urolithiasis in pediatric patients. This study aimed to evaluate th...

Response surface methodology was used to optimize media components such as carbon and nitrogen (simple and complex) sources, mineral agents and growth factors (B vitamins, amino acids) for enhancing the biomass production of Lactobacillus rhamnosus PEN. For screening experiment the following carbon sources were selected: glucose, glucose+pyruvate, glucose+citrate, glucose+lactate, galactose, fr...

INTRODUCTION This study aimed to compare the efficacy and safety of quadruple therapy containing doxycycline and routine quadruple therapy for Helicobacter (H.) pylori rescue eradication in patients who had failed the one-week triple therapy. METHODS Patients who failed the first-line eradication therapy were allocated into two groups. Group A patients (n = 43) were administered esomeprazole ...

Prior studies with carbonic anhydrase (CA) inhibitors implicated mitochondrial CA in ureagenesis and gluconeogenesis. Subsequent studies identified two mitochondrial CAs. To distinguish the contribution of each enzyme, we studied the effects of targeted disruption of the murine CA genes, called Car5A and Car5B. The Car5A mutation had several deleterious consequences. Car5A null mice were smalle...

PURPOSE This study was designed to develop and validate two simple, rapid, and economical UV-spectrophotometric and the first-order derivative methods using the area under curve method for estimation of diacerein in bulk and in capsule formulation. MATERIALS AND METHODS In this study, hydrotrophic solution of 8 M urea and 0.5 M potassium citrate were employed as the solubilizing agent to solu...

An essential first step in investigations of viruses in soil is the evaluation of viral recovery methods suitable for subsequent culture-independent analyses. In this study, four elution buffers (10% beef extract, 250 mM glycine buffer, 10 mM sodium pyrophosphate, and 1% potassium citrate) and three enumeration techniques (plaque assay, epifluorescence microscopy [EFM], and transmission electro...
