Hydrogen-rich saline attenuates heart dysfunction by restoring fatty acid oxidation

In Animal studies, Cardiovascular by CHESS

Sepsis is common in intensive care units (ICU) and is associated with high mortality. Cardiac dysfunction complicating sepsis is one of the most important causes of this mortality. This dysfunction is due to myocardial inflammation and reduced production of energy by the heart. A number of studies have shown that hydrogen-rich saline (HRS) has a beneficial effect on sepsis. Therefore, …

Cardioprotective effect of hydrogen-rich saline on myocardial infarction

In Animal studies, Cardiovascular by CHESS

Infusion with hydrogen gas-saturated saline has recently been reported to exert antioxidant and anti-inflammatory activity that may protect against organ damage induced by oxidative stress. Therefore because oxidative stress plays a significant role in the pathophysiology of myocardial infarction (MI), the aim of this study was to investigate whether hydrogen-rich saline has cardioprotective effects against isoproterenol-induced MI in rats. An …

Effects of hydrogen-rich saline on Akt/GSK3╬▓ signaling pathways and cardiac function

In Animal studies, Cardiovascular by CHESS

This study explored the effects of hydrogen-rich saline on Akt/GSK3╬▓ signaling pathways and cardiac function during myocardial ischemia-reperfusion (I/R) in rats. A total of 150 healthy male Sprague-Dawley rats were selected and divided randomly into 5 groups of normal control (I), sham operation (II), myocardial ischemia-reperfusion (III), hydrogen-rich saline (IV) and normal saline group (V) (n = 30 each). Group …

Hydrogen-rich saline with lactic acid alleviate myocardial reperfusion injury

In Animal studies, Cardiovascular by CHESS

This study investigated whether pharmacological postconditioning with lactic acid and hydrogen rich saline can provide benefits similar to that of mechanical postconditioning. To our knowledge, this is the first therapeutic study to investigate the co-administration of lactic acid and hydrogen. SD rats were randomly divided into 6 groups: Sham, R/I, M-Post, Lac, Hyd, and Lac + Hyd. The left coronary …

Hydrogen-rich water protects against ischemic brain injury by regulating calcium buffering proteins

In Animal studies, Cardiovascular, Nervous system by CHESS

Hydrogen-rich water (HRW) has anti-oxidant activities, and it exerts neuroprotective effects during ischemia-reperfusion brain injury. Parvalbumin and hippocalcin are two calcium buffering proteins, which are involved in neuronal differentiation, maturation and apoptosis. The aim of this study was to investigate whether HRW could moderate parvalbumin and hippocalcin expression during ischemic brain injury and glutamate toxicity-induced neuronal cell death. Focal brain …

Hydrogen-rich saline attenuates vascular smooth muscle cell proliferation and neointimal hyperplasia

In Animal studies, Cardiovascular by CHESS

Hydrogen-rich saline has been reported to prevent neointimal hyperplasia induced by carotid balloon injury. The purpose of the present study was to further investigate the molecular mechanisms underlying this phenomenon. Daily injection of a hydrogen-rich saline solution (HRSS) in rats was employed to study the effect of hydrogen on balloon injury-induced neointimal hyperplasia and the neointima/media ratio was assessed. HRSS …

Hydrogen attenuates left ventricular hypertrophy in hypertension

In Animal studies, Cardiovascular by CHESS

In hypertensive animals and patients, oxidative stress represents the primary risk factor for progression of left ventricular hypertrophy. Recently, it has been demonstrated that hydrogen, as a novel antioxidant, can selectively reduce hydroxyl radicals and peroxynitrite anion to exert therapeutic antioxidant activity. In the current study, we explored the effect of chronic treatment with hydrogen-rich saline (HRS) on left ventricular …

Chronic hydrogen-rich saline treatment attenuates vascular dysfunction in rats

In Animal studies, Cardiovascular by CHESS

In hypertensive patients, increased oxidative stress is thought to be one important cause of vascular dysfunction. Recently, it has been suggested that hydrogen exerts a therapeutic antioxidant activity by selectively reducing hydroxyl radical and peroxynitrite, the most cytotoxic chemicals of reactive oxygen species (ROS). Herein, we investigated the protective effect of chronic treatment with hydrogen-rich saline (HRS) against vascular dysfunction …

The effect of hydrogen gas on a mouse bilateral common carotid artery occlusion

In Animal studies, Cardiovascular by CHESS

In recent studies, molecular hydrogen selectively reduced the levels of hydroxyl radicals in vitro and exerted a therapeutic anti-oxidant activity in a rat middle cerebral artery occlusion model. The aim of this study was to investigate the effect of hydrogen gas on a mouse bilateral common carotid artery occlusion (BCCAO) model. Male C57BL/6J mice were subjected to transient BCCAO with …

Hydrogen inhalation improves functional outcomes after cardiac arrest

In Animal studies, Cardiovascular by CHESS

All clinical and biological manifestations related to postcardiac arrest (CA) syndrome are attributed to ischemia-reperfusion injury in various organs including brain and heart. Molecular hydrogen (H(2)) has potential as a novel antioxidant. This study tested the hypothesis that inhalation of H(2) gas starting at the beginning of cardiopulmonary resuscitation (CPR) could improve the outcome of CA.┬áVentricular fibrillation was induced by …
