The nonfiltering kidney model was used to determine whether sodium or potassium inhibits renin secretion in the absence of a functional macula densa in dogs with thoracic inferior vena caval constriction. The control rate of renin secretion was high, and decreases were readily recognized. After control observations, hypertonic sodium chloride or hypertonic potassium chloride was infused into th...

Oral administration of 1 ml of 3.42 M NaCl solution to rats induced spermidine/spermine N 1-acetyltransferase (SSAT) activity in gastric mucosa as well as ornithine decarboxylase (ODC) activity. SSAT activity increased and peaked at 5 h and again at 7 h, whereas ODC activity peaked at 6 h. SSAT mRNA also increased after 3.42 M NaCl administration to an extent similar to the increase in SSAT act...

BACKGROUND The use of hypertonic crystalloid solutions, including sodium chloride and bicarbonate, for treating severe sepsis has been much debated in previous investigations. We have investigated the effects of three crystalloid solutions on fluid resuscitation in severe sepsis patients with hypotension. METHODS Ninety-four severe sepsis patients with hypotension were randomly assigned to th...

among the environmental stresses, salinity is a major limiting factor in world legumes production is considered. in this study, sodium chloride and salicylic acid interaction on growth parameters were investigated in greenhouse with factorial arrangement in randomized complete block design with three replications. the plant consisted of three cultivars of lentil (kimiya, kermanshah and gachsara...

background: complications of ventolin as the most common drug used for bronchiolitis are widely known. the present study was conducted to determine the efficacy of hypertonic saline 3%, compared with ventolin, for treatment of acute bronchiolitis in children.   methods : this double-blinded clinical trial study was conducted in hajar hospital, shahrekord, iran, from 2011 to 2012. a total of 70 ...

1. The effect of the bathing solution tonicity on the mechanical properties of the anterior byssal retractor muscle (ABRM) of Mytilus edulis was examined. 2. The rate of relaxation of contracture tension produced by acetylcholine (ACh) was greatly reduced when the bathing solution tonicity was increased by adding NaCl, KCl or LiCl after the removal of ACh, whereas a decreased tonicity increased...

Intrabronchial injections of isotonic as well as of hypotonic solutions of sodium chloride or even of distilled water cause no pulmonary lesions. Intrabronchial injections of mercuric chloride even in a dilution of 1:10,000 cause a marked pulmonary lesion. The lesion is not of an inflammatory character; it consists of congestion, formation of thrombi, and hemorrhage. Intrabronchial injections o...

BACKGROUND AND OBJECTIVES Cerebral relaxation during intracranial surgery is necessary, and hiperosmolar therapy is one of the measures used to this end. Frequently, neurosurgical patients have sodium imbalances. The objective of the present study was to quantify and determine cerebral relaxation and duration of hydroelectrolytic changes secondary to the use of mannitol versus hypertonic isonco...
