the viewpoint of not only animal welfare but also the reliability of pharmacological studies. The type of anesthetics used may vary depending on the type of experiment required or the study design. Some anesthetics have cardioor renoprotective effects, which may be relevant in designing ischemiareperfusion protocols. Several studies have examined the influence of commonly used anesthetics on th...

ever since studies on uranium miners established the presence of a positive risk coefficient for the occurrence of lung cancer in miners exposed to elevated levels of 222rn and its progeny, there was a great upsurge of interest in the measurement of 222rn in the environment and considerable data is generated on the levels of 222rn in the environment across the worlds and is periodically reporte...

In the presented work, we have assessed features of peripheral oxygenation in children with congenital malformations surgical profile under various types combined anesthesia.
 The aim study. To assess state newborns and infants anesthetic support.
 Materials research methods. A retrospective study included 150 profile, depending on anesthesia (inhalation + regional anesthesia; inhalat...

INTRODUCTION Inhalation injury in combination with a severe thermal injury increases mortality. Alterations in inflammatory mediators, such as cytokines, contribute to the incidence of multi-organ failure and mortality. The aim of the present study was to determine the effect of inhalation injury on cytokine expression in severely burned children. METHODS Thirty severely burned pediatric pati...

1 A'-trans-tetrahydrocannabinol, (A'-THC) produces bronchodilatation in asthmatic patients. 2 Administered in 63 jl metered volumes containing 50-200 jg by inhalation from an aerosol device to patients judged to be in a steady state, it increased peak expiratory flow rate (PEFR) and forced expiratory volume in 1 second (FEVI). 3 The rate of onset, magnitude, and duration of the bronchodilator e...

Inhalation sedation utilizing nitrous oxide-oxygen has been a primary technique in the management of dental fears and anxieties for more than 150 years and remains so today. Though other, more potent, anesthetics have been introduced, nitrous oxide is still the most used gaseous anesthetic in the world. Administered properly with well-maintained equipment, the nitrous oxide-oxygen technique has...

welders exposure to nickel and hexavalent chromium in welding fumes is associated with increase of cancer risk in welders. in this study we calculated cancer risk due to exposure to these compounds in welders.the role of exposure parameters in welders on derived incremental lifetime cancer risk were determined by stochastic modeling of cancer risk. input parameters were determined by field inve...

introduction: oxygen is a drug and physician and nurses should be familiar with the effects and potential risks of oxygen therapy. the current study aimed to assess familiarity of physicians and nurses with various aspects of oxygen therapy. method: in this cross sectional study, the familiarity of physicians and nurses with various aspects of oxygen therapy in a teaching hospital was evaluated...

We examined the effects of odorant inhalation on the sleep-wake states in rats. Odorants used in the experiment were clove, jasmine, lavender, lemon, peppermint, pine, rose, sandalwood, valerian, and ylang-ylang. Valerian and rose inhalation significantly prolonged the pentobarbital-induced sleeping time, whereas lemon inhalation significantly shortened it. The effect of valerian inhalation was...
