Abstract 19253: Chronic Hypobaric Hypoxia and Chronic Intermittent Hypobaric Hypoxia in Rats Leads to a Mismatch in the ADMA-NO Pathway

Circulation, 2013
Introduction: Chronic Hypoxia (CH) as well as chronic intermittent hypoxia (CIH) are associated with pathophysiological conditions like acute/chronic mountain sickness and pulmonary hypertension. In the manifestation of these diseases the endothelium and the L-arginine/NO pathway plays a crucial role.

Improvement of myocardial perfusion in coronary patients after intermittent hypobaric hypoxia

Journal of Nuclear Cardiology, 2006
Persons living at high altitude (exposed to hypoxia) have a greater number of coronary and peripheral branches in the heart than persons living at sea level. In this study we investigated the effect of intermittent hypobaric hypoxia on myocardial perfusion in patients with coronary heart disease.We studied 6 male patients (aged>or=53 years) with severe

Erythropoietin acute reaction and haematological adaptations to short, intermittent hypobaric hypoxia

European Journal of Applied Physiology, 2000
This study aimed to determine whether brief hypoxic stimuli in a hypobaric chamber are able to elicit erythropoietin (EPO) secretion, and to effectively stimulate erythropoiesis in the short term. In two different experiments, a set of haematological, biochemical, haemorheological, aerobic performance, and medical tests were performed in two groups of ...

Involvement of Autonomic Nervous System in Antiarrhythmic Effect of Intermittent Hypobaric Hypoxia

Bulletin of Experimental Biology and Medicine, 2017
We studied the involvement of the autonomic nervous system in the antiarrhythmic effect of intermittent hypobaric hypoxia modeled by daily placing the rats into an altitude chamber at 405 mm Hg (5000 m above sea level). The antiarrhythmic effect of hypoxia was observed on the model of acute coronary occlusion/reperfusion in vivo, but not during ...

The effects of NO on the urea cycle pathway in short-term intermittent hypobaric hypoxia in rats

Respiratory Physiology & Neurobiology, 2021
Short-term hypoxic states can influence the health and life activities of lowlanders who travel shortly to high altitudes, in transitory situations, such as surgical ischemia-reperfusion (to one or several organs), and in some sporting activities, such as parachuting and extreme skiing, mountain rescue teams, regular commercial flight crews, in which ...

Chronic intermittent hypobaric hypoxia ameliorates iron metabolism disorder through ferritinophagy in collagen-induced arthritis mice.

Journal of Trace Elements in Medicine and Biology
AIM Rheumatoid arthritis (RA) is a chronic inflammatory disease that is often complicated by anemia of chronic disease (ACD). Studies have shown that the development of ACD is closely related to iron metabolism disorder.

Comparison of the effects of chronic intermittent hypobaric hypoxia and continuous hypobaric hypoxia on hemodynamics in rats.

Sheng li xue bao : [Acta physiologica Sinica], 2015
The aim of this study is to investigate the effects of chronic intermittent hypobaric hypoxia (IHH) and chronic continuous hypobaric hypoxia (CHH) on hemodynamics under basic normoxia and acute hypoxia conditions and to find the difference of two types of chronic hypoxia.

Myocardial ischemia and reperfusion (I/R) is a common problem in clinic and there is no satisfactory method for prevention or treatment of I/R injury so far. Chronic intermittent hypobaric hypoxia (CIHH), similar to the concept of ischemia preconditioning (IPC)or altitude hypoxia adaptation (AHA), has been recognized to confer a protective effect on ...
