Rev. bras. anestesiol; 67 (1), 2017
Abstract Background and objectives: In this study it was aimed to examine the histological and morphometric effects on cartilage structure of intra-articular application of levobupivacaine to the shoulder joint. Methods: In twenty New Zealand adult male rabbits, 35 shoulders were used for the study and...

Perineural dexmedetomidine effects on sciatic nerve in rat

Rev. bras. anestesiol; 67 (1), 2017
Abstract The present study was designed to test the hypothesis that high dose dexmedetomidine would increase the duration of antinociception to a thermal stimulus in a rat model of sciatic nerve blockade without causing nerve damage. The rats were anesthetized with isoflurane. After electromyography (EMG...

Effects of lidocaine and magnesium sulfate in attenuating hemodynamic response to tracheal intubation: single-center, prospective, double-blind, randomized study

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background and objectives: Hemodynamic response to airway stimuli is a common phenomenon and its management is important to reduce the systemic repercussions. The objective of this study is to compare the efficacy of intravenous magnesium sulfate versus lidocaine on this reflex hemodynamics aft...

Anesthesia for pulmonary trunk aneurysmorrhaphy

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background and objectives: The aneurysm in the pulmonary trunk is a rare disease. Because of its location, a rupture can lead to right ventricular failure and sudden death. Aneurysmorraphy is the most widely used surgical treatment in these cases. The aim of this study is to report a successful...

The effects of intra-cerebroventricular administered rocuronium on the central nervous system of rats and determination of its epileptic seizure-inducing dose

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background: The aim of this study was to investigate the effects of intracerebroventricularly administered rocuronium bromide on the central nervous system, determine the seizure threshold dose of rocuronium bromide in rats, and investigate the effects of rocuronium on the central nervous syste...

In vivo and in vitro activity of oil extract of garlic (Allium sativum Linnaeus) against Schistosoma japonicum cercariae

Abstract: INTRODUCTION: The activity of garlic oil extract against Schistosoma japonicum cercariae was evaluated. METHODS: The in vitro and in vivo cercaricidal activities against S. japonicum larvae were determined. RESULTS: Exposure to ≥ 10-6 (v/v) garlic emulsions for 30 min led to 100% cer...

Emergence of colistin resistance in the largest university hospital complex of São Paulo, Brazil, over five years

Braz. j. infect. dis; 21 (1), 2017
Abstract Colistin resistance involving Gram-negative bacilli infections is a challenge for health institutions around of the world. Carbapenem-resistance among these isolates makes colistin the last therapeutic option for this treatment. Colistin resistance among Enterobacteriaceae, Acinetobacter spp., a...

Mem. Inst. Oswaldo Cruz; 112 (2), 2017
BACKGROUND Gene reporter-fluorescent cells have emerged as alternative method for drug screening. OBJECTIVE Achievement of constitutive expression of fluorescent protein GFP by Leishmania braziliensis as alternative method for drug screening. METHODS L. braziliensis-GFP was generated using Leishmania...
