The electrical responses of the smooth muscle cells of the rabbit common carotid artery to extracellular stimulation were studied in isotonic and hypertonic solution (1.7 times normal tonicity) with microelectrodes. No spontaneous electrical or mechanical activity was recorded when the tissue was in either isotonic or hypertonic solution. The voltage-current relation of smooth muscle cells in t...

Infusions of hypertonic dextrose or NaCl solutions reduce resistance in several vascular beds of experimental animals. To study the response in man, 60 intrabrachial arterial jet infusions of hypertonic dextrose solution or hypertonic NaCl solution, each at 3 dose levels (1, 2, and 4 milliosmols/min), were made in 19 male student volunteers aged 21 to 29 years. Limb blood flow was measured by c...

The effect of hypertonic solutions on the caffeine- and KCl-induced contractures of isolated fibers of frog skeletal muscle was tested. Hypertonic solutions, twice the normal osmotic strength, prepared by adding NaCl or sucrose, potentiate the caffeine-induced contractures. The fibers may develop tensions of 3.6 kg/cm(2) of fiber transverse section. The same hypertonic medium reduced the peak t...

We were aimed with this case report that evaluate the efficiency of 7.2% hypertonic saline infusion on echocardiographic parameters in a 5-months-old male Kangal Shepherd crossbreed dog systemic inflammatory response syndrome (SIRS). For propose initial referral to clinic, SIRS was defined clinical and laboratory finding. Hypertonic (7.2%) administered at intravenously 4 ml/kg (1.6 ml/kg/min) f...

Background One of the main reasons for discharge lung donors is pulmonary edema. It may be associated to hemodynamic shock frequently present among organ donors. There is no experience using hypertonic saline solution among lung donors with hypovolemic shock. The aim of this study is to evaluate hypertonic solution in pulmonary function of lung donor model with hypovolemic shock using the ex-vi...

STUDY OBJECTIVES Hypertonic saline solution inhalation is suspected to produce airway inflammation. DESIGN The aim of this study was to verify this hypothesis by measuring inflammatory markers in exhaled breath condensate (EBC) collected before and after sputum induction with hypertonic and isotonic saline solution. PATIENTS AND METHODS We enrolled 10 patients with asthma, 10 patients with ...

Hypertonic saline prevents vascular adherence of neutrophils and ameliorates ischemic tissue injury. We hypothesized that hypertonic saline attenuates N-formyl-methionyl-leucyl-phenylalanine (fMLP)-stimulated expression of adhesion molecules on human polymorphonuclear leukocytes (PMNLs). fMLP-stimulated up-regulation of beta2-integrins was diminished by hypertonic saline but not by hypertonic c...
