It is common to use muscle relaxants, such as succinyl choline to produce muscle relaxation during tracheal intubation. Based on some new researches alfentanyl was reported to be used without succinyl choline for tracheal intubation. The goal of this study was to evaluate the quality of tracheal intubation during general anesthesia with alfentanyl in order to see whether it can be used as a sub...
Background and Objective: Cardiovascular disease is the most common cause of death and the major cause of disability in many countries, including Iran, and it causes stress and tension in afflicted patients. The aim of this study was to determine the effect of progressive muscle relaxation on perceived stress in patients with myocardial infarction. Materials and Methods: In this randomized clin...
Introduction: One of the most common complication of myocardial infarction (MI) is subsequent psychological problems including anxiety and depression which most patients experience, reduces vital function and increases mortality. Clinical symptoms such as anxiety, preoccupation and negative ideas about probable ensuing cardiac attack imperils physical and mental health of patients. The object...
A two-compartment, flat-sheet preparation of rat colon was devised, which enabled exclusive measurement of longitudinal muscle activity during the ascending and descending phases of the peristaltic reflex. A previous study using longitudinal muscle strips revealed the operation of an integrated neuronal circuit consisting of somatostatin, opioid, and VIP/pituitary adenylate cyclase-activating p...
OBJECTIVE To characterize the isometric contractility of Bufo gastrocnemius ex vivo in light of the rest tension. METHODS Bufo gastrocnemius treated with SOD inhibitor and ascorbate was stimulated electrically (12 V DC, 2 ms duration with a 2 s interval) to record the tension within 10 min. Weighted fitting to the relaxation curve of the tension below 90% of the peak tension with a mono-expon...
BACKGROUND Muscle relaxants induce vascular smooth muscle relaxation by inducing synthesis of the prostaglandins that influence vasomotor tone. However, the effects of muscle relaxants on endothelial cells and tissues following injury by reactive oxygen species (ROS) are unclear. We tested the effects of the muscle relaxants vecuronium and rocuronium on impaired acetylcholine (ACh)-induced rela...
The antinociceptive effect of Elaeagnus angustifolia fruits was studied in mice. The antinociceptive effect of ethanolic and boiling water extracts was studied using two thermal stimuli, the hot-plate and tail-flick tests. The intraperitoneal and oral administration of the ethanolic extract of seed 0.75-7.00 g/kg), but not pericarp and medulla had significant antinociceptive activity in the...
Introduction: Postpartum blues is one of the complications that can affect the health of the mother and how she communicates with the baby, and as a result, her physical and mental health. Therefore, its prevention can influence the mental health of the family. Objective: This study aimed to determine the effect of Progressive Muscle Relaxation (PMR) therapy on the postpartum blues of high-ris...
The esophagogastric junction (EGJ) is guarded by two sphincters, a smooth muscle lower esophageal sphincter (LES) and a skeletal muscle crural diaphragm. These two sphincters relax simultaneously under certain physiological conditions, i.e., swallowing, belching, vomiting, transient LES relaxation, and esophageal distension. Esophageal distension-induced crural diaphragm relaxation is mediated ...
Gripping objects during everyday manual tasks requires the coordination of muscle contractions and muscle relaxations. The vast majority of studies have focused on muscle contractions. Although previous work has examined the motor cortex during muscle relaxation, the role of brain areas beyond motor cortex remains to be elucidated. The present study used functional magnetic resonance imaging to...
