OBJECTIVE Methylene blue (MB), a free-radical scavenger inhibiting the production and actions of nitric oxide, may counteract excessive vasodilatation induced by nitric oxide during cardiac arrest. Effects of MB in cardiac arrest and cardiopulmonary resuscitation were investigated. DESIGN Randomized, prospective, laboratory animal study. SETTING University animal research laboratory. SUBJ...

Cystic fibrosis (CF) is a recessive genetic disease that requires aggressive therapies to slow the disease progression. CF is a complex disorder that primarily affects the digestive system and the lungs. A major characteristic of CF is lung disease, which is responsible for the majority of CF-related deaths. CF is caused by an absent or deficient CF transmembrane regulator, which is a protein r...

A high neutrophil count is often found in induced sputum compared to bronchoalveolar lavage fluid (BALF). This study investigated whether such a high neutrophil count may be a response to inhaled hypertonic saline or that the airway compartment sampled by induced sputum has a higher concentration of neutrophils than BALF. Saliva and induced sputum samples were taken at 10 and 20 min following i...

BACKGROUND Patients with cystic fibrosis are known to have decreased mucociliary clearance. It has previously been shown that inhalation of a 7.0% solution of hypertonic saline significantly improved mucociliary clearance in a group of adult patients with cystic fibrosis. The aim of this study was to measure the response to increasing concentrations of inhaled hypertonic saline. METHODS Ten p...

OBJECTIVE Most surgeons inject scoloidal materials into the cyst before or after its removal, since any contamination to normal sites will cause re-growth of the same cyst. The aim of this study was to determine the lethal effect of hypertonic saline at different doses and different times on protoscolexes of lung and liver. METHODS The livers and lungs of killed animals with hydatid cyst dise...

BACKGROUND Chronic lower back pain with or without radiculopathy represents an important medical, social, and economic problem. Many treatment modalities and techniques, including surgery and epidural administration of steroids, have been used to manage this pain. Hypertonic saline, which has been used as an adjunct to percutaneous epidural adhesiolysis, can also be injected via a transforamina...

Background. Angiotensin 1-7 (Ang1-7) plays an important role in renal circulation. Hemorrhagic shock (HS) may cause kidney circulation disturbance, and this study was designed to investigate the renal blood flow (RBF) response to Ang1-7 after HS. Methods. 27 male Wistar rats were subjected to blood withdrawal to reduce mean arterial pressure (MAP) to 45 mmHg for 45 min. The animals were treated...

BACKGROUND The optimal prehospital fluid for the treatment of hypotension is unknown. Hypertonic fluids may increase circulatory volume and mute the pro-inflammatory response of the body to injury and illness. The purpose of this systematic review is to determine whether in patients presenting with hypotension in the prehospital setting (population), the administration of hypertonic saline (int...
