Bacterial translocation is a major cause of multiple organ dysfunction syndrome in critical illness, and its management is an important therapeutic strategy. In this study, the authors focused on the key factors responsible for bacterial translocation including the intestinal microbiome and investigated the impact of molecular hydrogen therapy as a countermeasure against bacterial translocation in a murine model of sepsis. …
Influence of hydrogen-rich saline on hepatocyte autophagy
The purpose of this study was to investigate the protective effect of hydrogen-rich saline (HRS) against liver ischaemia-reperfusion combined resection injury. Eighteen miniature pigs were randomly divided into three groups: a sham operated group (sham group, laparoscopic liver ischaemia-reperfusion combined resection injury group (IRI group), and a hydrogen-rich saline intervention group (IRI + HRS group). Samples of hepatic tissue and …
Hydrogen protects against hepatic injury
Hydrogen-rich saline (HRS) has antioxidative, anti-inflammatory and anti-apoptotic properties. The authors investigated the effects of hydrogen on hepatic ischemia-reperfusion (I/R) and laparoscopic hepatectomy in swine. Twenty-one healthy Bama miniature pigs were randomly divided into the sham group, ischemia-reperfusion injury (IRI) group, HRS-5 (5 mL/kg) group, and HRS-10 (10 mL/kg) group. HRS was injected through the portal vein 10 min before reperfusion and at …
Hydrogen-rich saline protects from oxygen glucose deprivation
Hydrogen is received as an inert gas that thought to be non-functional in vivo previously. Recently, emerging evidences showed that in ischemia/reperfusion (IR) condition, hydrogen reduced cellular reactive oxygen species (ROS) production and ameliorated cell apoptosis. However, the underlying mechanism of hydrogen on IR-induced apoptosis remains elusive. Here the authors tried to unravel the mode of action of hydrogen with …
Exercise and hydrogen-rich saline protect from myocardial injury
It has been reported that hydrogen-rich saline (HRS) water reduces oxidative stress, and early aerobic exercise (eAE) acts an efficient exercise preconditioning (EP) against cardiac I/R injury. However, whether early aerobic exercise combined with hydrogen-rich saline (eAE-HRS) water can more effectively protect myocardial damage induced by acute myocardial infarction (MI) is still unknown. This study was aimed to evaluate the …
Hydrogen-rich saline for neonatal hypoxic-ischemic encephalopathy
Neonatal hypoxic ischemic encephalopathy (HIE) is an important cause of neonatal death and disability. At present, there is no unified standard and specialized treatment method for neonatal HIE. In clinical practice, the authors have found that a gap remains between preclinical medical research and clinical application in the treatment of neonatal HIE. To promote an organic combination of preclinical research …
Inhaled hydrogen ameliorates bowel dysfunction
Gastrointestinal dysmotility frequently occurs during sepsis and multiple organ failure, remaining a major cause of morbidity and mortality in critically ill patients. Previous studies have shown that hydrogen, a new therapeutic gas, can improve various organ damage associated with sepsis. In this study, the authors investigated the protective efficacies of inhaled hydrogen against lipopolysaccharide (LPS)-induced ileus. Sepsis was induced in …
Molecular hydrogen for neuroprotection
Oxidative stress and neuroinflammation cause many neurological disorders. Recently, it has been reported that molecular hydrogen (H2) functions as an antioxidant and anti-inflammatory agent. The routes of H2 administration in animal model and human clinical studies are roughly classified into three types, inhalation of H2 gas, drinking H2-dissolved water, and injection of H2-dissolved saline. This review discusses some of the …
Hydrogen gas attenuates myocardial ischemia
The aim of this study was to investigate the effect of inhaling hydrogen gas on myocardial ischemic/reperfusion(I/R) injury in rats. Seventy male Wistar albino rats were divided into five groups at random as the sham group (Sham). The I/R group (I/R), The ischemic postconditioning group (IPo), The I/R plus hydrogen group (IH2) and the ischemic postconditioning plus hydrogen group (IPoH2). …
Effects of hydrogen gas inhalation on endometriosis
Oxidative stress is generated during the pathophysiology of endometriosis (EMT). Hydrogen (H2) has been demonstrated as a gas antioxidant. The aim of the present study is to evaluate the protective effect of H2 on EMT in rats. Sprague Dawley rats with surgically induced EMT were randomly received the inhalation of 67% H2-33% oxygen (O2) mixture (1 h/d, 4 weeks) immediately …
