Screening performance of Ultrasonographic B-lines in Detection of Lung Contusion following Blunt Trauma; a Diagnostic Accuracy Study.

Introduction: Chest ultrasonography is routinely used in evaluation of chest trauma for diagnosis of pulmonary injury. This study aimed to evaluate the accuracy of B-Lines for diagnosing lung contusion in patients with blunt trauma of the chest.

Methods: Trauma patients who met the inclusion criteria were enrolled in the study and underwent ultrasonography by trained emergency medicine residents.

The effect of nebulized magnesium sulfate in the treatment of moderate to severe asthma attacks: a randomized clinical trial.

Objective: Thirty percent of people with asthma do not respond to standard treatment, and complementary therapies are needed. The objective of this study was to investigate the impact of inhaled magnesium sulfate on the treatment response in emergency department (ED) patients with moderate to severe attacks of asthma.

Methods: This study is a randomized controlled trial, enrolling patients with moderate to severe asthma in the ED.

Oral verapamil in paroxysmal supraventricular tachycardia recurrence control: a randomized clinical trial.

Background: Adenosine is the first-line medication in patients with paroxysmal supraventricular tachycardia. Because it is cleared so rapidly from the circulation, recurrence of paroxysmal supraventricular tachycardia after initial successful conversion may occur.

Objective: This study was conducted to evaluate the role of oral verapamil administration to control early recurrences of paroxysmal supraventricular tachycardia after adenosine infusion.

Growth optimization of Zataria multiflora Boiss. tissue cultures and rosmarinic acid production improvement.

In order to improve the growth of Zataria multiflora tissues in vitro experiments in different hormonal treatments and culture media were carried out. Shoot cultures, established from plantlets shoot apex, were treated by different levels of 6-benzylaminopurine and 1-naphtalen acetic acid added to Murashige and Skoog medium with two conditions of active charcoal. The highest proliferation rate was obtained with 1 mg L(-1) 6-benzylaminopurine, without charcoal.
