Potential Impact of 3% Hypertonic Saline Infusion on Tramadol Poisoning-Induced Electrocardiogram Changes; a Randomized Clinical Trial.

Introduction: Tramadol is a synthetic analgesic with weak mu-opioid receptor agonist activity. Tramadol overdose is associated with adverse cardiac effects due to inhibiting cardiac Na+ and K+ channels. This study aimed to investigate the potential ameliorative role of 3% hypertonic saline on the electrocardiogram (ECG) changes in patients presenting with tramadol poisoning.

Sound level analysis in endotracheal tube obstruction in spontaneous breathing and mechanical ventilation-an animal model study.

Endotracheal tube (ETT) obstruction, either complete or partial, is a serious life threatening complication in intubated patients. Therefore, implementing a practical method to diagnose this condition is vital. Alteration in respiratory sound signals caused by ETT occlusion can be used for early detection of obstruction.

Study on diuretic activity of saffron (stigma of Crocus sativus L.) Aqueous extract in rat.

Saffron is the most expensive spice in the world and consists of the dried stigmas of Crocus sativus L. It is used as food coloring and flavoring in food industry and traditional cooking and also in folk medicine as antispasmodic, carminative, stomachic, expectorant, aphrodisiac and cardiotonic.
