thiopental sodium is an ultra short-acting barbiturate. due to its redistribution characteristic, its first injection has a short term effect. in order to elongate its anesthesia duration, more injections are needed. as these additional injections extend the recovery length , weaken respiration and causes other dangerous effects; its repeated use is considered unsafe. citicoline is a natural su...
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...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

Aim: The present study was purported to determine the value and applicability of positive end-inspiratory pressure (PEIP) for the in vivo assessment of airways responsiveness (AR) in an experimental model of asthma induced in rats by ovalbumin (OVA) sensitization. Materials and methods: Male Sprague–Dawley rats were randomized in two groups: a control group (CON, n = 8) and a group sensitized b...
There are many medications that can be utilized to sedate children undergoing fMR examinations. The most frequently used drugs are chloral hydrate, thiopenthal, phenobarbital, propofol, and fentanyl. These medications have some secondary effects on the electrical and metabolic activity of the cortex, cerebral blood flow(CBF), cerebral blood volume(CBV), and tissue oxygen extraction. These effec...
BACKGROUND Pain in infancy is a developmental process. Due to the underdeveloped pain pathways in the spinal cord, the threshold of stimulation and sensation of pain is low at birth and has potential impacts on increasing the central effects of pain. Primary trauma during infancy can cause long term changes in structure and function of pain pathways that continue until adulthood. Lack of pain m...

We studied the ability of the ECG to detect pathological changes in isoproterenol-induced remodeling of rat heart. Myocardial hypertrophy in rats was induced by repeated injections of isoproterenol (5 mg/kg s.c. 7 days, Iso5, n=7). Single overdose of isoproterenol (150 mg/kg s.c., Iso150, n=7) evoked myocardial infarction followed with ventricular remodeling. The electrocardiograms were recorde...
