Background: Well-controlled clinical studies in the developed world have shown that probiotics can shorten the duration of acute non-bacterial diarrhea. We aimed to evaluate the efficacy of a probiotic consisting of a mixture of Lactobacillus acidophilus and Bifidobacterium bifidum in the treatment of young children with acute diarrhea in Mashad, Iran Methods: Sixty-two hospital inpatients aged...

The effects of external divalent cations on drug-receptor interaction were examined using guinea pig taenia. The effects of histamine on membrane potential of taenia in various solutions were also examined using the sucrose gap method. Ca2+ and Me2+ played an important role in the combination of histamine with its receptor. Sr2+, Mn2+ and Co2+ do not substitute for. Ca2+ and Me2+ in this intera...

Mechanisms underlying action potential generation in the newt olfactory receptor cell were investigated by using the whole-cell version of the patch-clamp technique. Isolated olfactory cells had a resting membrane potential of -70 +/- 9 mV. Injection of a depolarizing current step triggered action potentials under current clamp condition. The amplitude of the action potential was reduced by low...

Blood glucose concentration, pH and standard bicarbonate concentration were measured in 70 anaesthetized children aged between 2 weeks and 22 months before and following surgery. The duration of starvation varied between 4 and 14 h (mean 5.8 h). The lowest blood-glucose concentration before operation was 2.9 mmol litre-1 (53 mg dl-1). Preoperative blood-glucose concentrations were not influence...

background: the advantages of coated orthodontic wires such as esthetic and their effectson reduced friction, corrosion and allergic reaction and the signifi cant consequences of plaque accumulation on oral health encouraged us to assess bacterial colonization on these wires. materials and methods: a total of 18 (9 upper and 9 lower) epoxy resin coated 16 × 22 nickeltitanium wires (spectra, gac...

cefquinome sulfate (cs) is a fourth-generation cephalosporin, which has been developed solely for veterinary use. it shows potent antibacterial activity against a broad spectrum of bacterial species. however, cefquinome is susceptible to hydrolysis, which limiting its clinical employment efficacies to some extent. so, in this study, to increase cefquinome sulfate biological half-life, a novel c...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...

The interaction between caffeine and calcium on the rate of desensitization of muscle postjunctional membrane (PJM) receptors during the sustained application of 0.27 mM carbamylcholine (CARB) has been studied in vitro on the sartorius muscle of the frog. The rate of PJM repolarization with CARB added to the solution bathing the muscle or the recovery of the effective transmembrane resistance (...
