Due to its anti-inflammatory and anti-oxidative effects, recent research has demonstrated that molecular hydrogen can serve as a new medical approach for depression, anxiety and traumatic brain injury. However, its potential effects on neurodevelopmental diseases, such as autism are still elusive. The present study aims to investigate the potential effects of hydrogen-rich water (HRW) administration on valproic acid (VPA)-induced autistic-like …
Hydrogen protects the neurons against lead-induced oxidative stress
Despite the well-known toxicity and the efforts to control its exposure, lead still has a serious health concern, particularly in young ages. Chelation therapy cannot correct the neurocognitive effects of chronic exposure. So, there is a requirement to test different protective agents for lead intoxication. Hydrogen-rich water (HRW) has gained attraction recently as an antioxidant. Four groups of rats received …
Hydrogen-rich water improves cognitive impairment
Alzheimer’s disease (AD) is characterised as a provoked inflammatory response and oxidative stress along with amyloid β peptide (Aβ) deposition and neurofibrillary tangles in the brain, and effective treatment is greatly needed. Molecular hydrogen, which has been proposed to be an antioxidant that selectively reduces reactive oxygen species, was found to exert beneficial effects in Aβ injection-induced cognitive dysfunction. However, …
FoxO1 and neuroprotective effects of hydrogen in vascular dementia
Vascular dementia (VD) is a heterogeneous group of brain disorders in which cognitive impairment is attributed to cerebrovascular pathologies. Autophagy, a self-cannibalization mechanism, has been demonstrated to be involved in VD progression. Molecular hydrogen is known for its powerful anti-oxidative, anti-apoptotic, and anti-inflammatory activities, and it is also involved in autophagy. However, the effects of hydrogen on VD remain unclear. …
Hydrogen-rich saline for neuropathic pain
Neuropathic pain is a chronic and intractable pain, with very few effective analgesics. It involves an impaired cell autophagy process. Hydrogen-rich saline (HRS) reportedly reduces allodynia and hyperalgesia in a neuropathic pain model; however, it is unknown whether these effects involve autophagy induction. The authors investigated the relationship between HRS and cell autophagy in a neuropathic pain model generated by …
Hydrogen-rich water ameliorates autistic-like behavioral abnormalities
Due to its anti-inflammatory and anti-oxidative effects, recent research has demonstrated that molecular hydrogen can serve as a new medical approach for depression, anxiety and traumatic brain injury. However, its potential effects on neurodevelopmental diseases, such as autism are still elusive. The present study aims to investigate the potential effects of hydrogen-rich water (HRW) administration on valproic acid (VPA)-induced autistic-like …
Molecular hydrogen inhalation attenuates postoperative cognitive impairment
Postoperative cognitive decline is a major clinical problem with high morbidity and mortality after surgery. Many studies have found that molecular hydrogen (H2) has significant neuroprotection against acute and chronic neurological injury by regulating inflammation and apoptosis. In this study, the authors hypothesized that H2 treatment could ameliorate the development of cognitive impairment following surgery. Adult male rats were subjected …
Hydrogen-rich saline attenuates brain injury induced by cardiopulmonary bypass
Cardiopulmonary bypass (CPB) is prone to inducing brain injury during open heart surgery. A hydrogen-rich solution (HRS) can prevent oxidation and apoptosis, and inhibit inflammation. This study investigated effects of HRS on brain injury induced by CPB and regulatory mechanisms of the PI3K/Akt/GSK3β signaling pathway. A rat CPB model and an in vitro cell hypoxia model were established. After HRS …
Hydrogen attenuates brain injury after cardiac arrest
Hydrogen-rich saline can selectively scavenge reactive oxygen species (ROS) and protect brain against ischemia reperfusion (I/R) injury. Endoplasmic reticulum stress (ERS) has been implicated in the pathological process of cerebral ischemia. However, very little is known about the role of hydrogen-rich saline in mediating pathophysiological reactions to ERS after I/R injury caused by cardiac arrest. The rats were randomly divided …
Hydrogen attenuates cognitive impairment via inhibition of mitochondrial dysfunction
The inhaled general anesthetic isoflurane has been shown to induce caspase-3 activation in vitro and in vivo. The underlying mechanisms and functional consequences of this activity remain unclear. Isoflurane can induce caspase-3 activation by causing accumulation of reactive oxygen species (ROS), mitochondrial dysfunction, and reduction in adenosine triphosphate (ATP) levels. This study aimed to investigate the protective effect of hydrogen, …
