Hypobaric Intermittent Hypoxia Attenuates Hypoxia-induced Depressor Response
BACKGROUND Hypobaric intermittent hypoxia (HIH) produces many favorable effects in the cardiovascular system such as anti-hypertensive effect. In this study, we showed that HIH significantly attenuated a depressor response induced by acute hypoxia. METHODOLOGY/PRINCIPAL FINDINGS Sprague-Dawley rats received HIH in a hypobaric chamber simulating an altitude of 5000 m. The artery blood pressure...
متن کاملChronic intermittent hypobaric hypoxia attenuates monocrotaline-induced pulmonary arterial hypertension via modulating inflammation and suppressing NF-κB /p38 pathway
Objective(s): Inflammation is involved in various forms of pulmonary arterial hypertension (PAH). Although the pathophysiology of PAH remains uncertain, NF-κB and p38 mitogen-activated protein kinase (p38 MAPK) has been reportedto be associated with many inflammatory mediators of PAH. This study aimed to evaluate the effect of chronic intermittent hypobaric hypoxia (CIHH) on pulmonary inflammat...
متن کاملChronic intermittent hypoxia increases infarction in the isolated rat heart.
Coronary heart disease is frequently associated with obstructive sleep apnea syndrome and treating obstructive sleep apnea appears to significantly improve the outcome in coronary heart disease. Thus we have developed a rat model of chronic intermittent hypoxia (IH) to study the influence of this condition on myocardial ischemia-reperfusion tolerance and on functional vascular reactivity. Wista...

متن کاملChronic intermittent hypobaric hypoxia ameliorates ischemia/reperfusion-induced calcium overload in heart via Na/Ca2+ exchanger in developing rats.
BACKGROUND/AIMS Chronic intermittent hypobaric hypoxia (CIHH) protects the heart against ischemia/reperfusion (I/R) injury. This study investigated the calcium homeostasis mechanism and the role of Na(+)/Ca(2+) exchanger (NCX) in the cardiac protective effect of CIHH in developing rats. METHODS Neonatal male rats received CIHH treatment or no treatment (control) in a hypobaric chamber simulat...
