BACKGROUND Current clinical treatment methods for refractory intracranial hypertension include elevation of the decubitus, ventilation adjustment, and use of hypertonic solutions such as hypertonic saline and mannitol solutions. Previous studies have shown that hypertonic solutions are particularly effective. Although several concentrations of saline solution have been proposed, a 3% solution i...

Hypertonic saline solutions have properties that may be advantageous for resuscitation. In both animal and human studies rapid improvements in cardiovascular status occur when hypertonic saline is administered to hypovolaemic subjects and the possible side effects of hypertonic solutions have not been shown to be of clinical importance. Hypertonic saline certainly has a potential role in resusc...

The efficacy of three hypertonic saline solutions for treating dialysis-induced hypotension in a randomized, blinded, crossover clinical trial of 10 patients (a minimum of three cycles per solution) was compared. Dialysis-induced hypotension, defined as a decrease in systolic blood pressure of at least 10 mm Hg or systolic blood pressure less than 100 mm Hg, was treated with an iv bolus of eith...

Objective(s): Nanoparticles of iron oxide (nFe2O3) are widely used in medicine and industry and could interfere with the brain processes associated with memory. The involvement of muscarinic cholinergic receptors in the process of memory formation has been confirmed. The present study aimed to investigate the possible interference of the cholinergic muscarinic receptors of the dorsal hippocampa...

BACKGROUND Many studies have shown that nicotine negatively impacts fracture healing and bone fusion processes. However, very little is known about its effect on tendon and ligament healing. The goal of the present study was to evaluate the effect of nicotine on tendon-to-bone healing. METHODS Supraspinatus tendons in both shoulders of seventy-two rats were transected and repaired to the hume...

OBJECTIVE(S) High blood glucose induces molecular, cellular, morphological and behavioral changes in the brain. Metabolic disturbances, contribute to the hippocampus injury and development of partial focal seizures. The aim of this study was to investigate the effects of infantile repeated hyperglycemia on neuronal density of hippocampal CA3 region in newborn Wistar male rats and its effect on ...

The ethidium bromide-demyelinating model (EB) was used to study remyelination in the brainstem under the use of cyclosporine (CsA). Wistar rats were submitted to intracisternal injection of 0.1% EB or 0.9% saline solution, and others were taken as histologic controls (group I). Within those injected with EB, some have not received immunosuppressive treatment (II); some were treated by intraperi...
