Hydrogen-rich saline reduced acute spinal cord contusion injury

In Animal studies, Nervous system by CHESS

In the present study, authors examined the mechanisms of hydrogen-rich saline, a reported therapeutic antioxidant, in the treatment of acute spinal cord contusion injury. Male Sprague-Dawley rats were used to produce a standardized model of contuses spinal cord injury (125 kdyn force). Hydrogen-rich saline was injected intraperitoneally (5 ml/kg) immediately, and at 24 and 48 h after injury. All rats …

Neuroprotective effects of hydrogen saline in neonatal hypoxia-ischemia rat model

In Animal studies, Nervous system by CHESS

Cerebral hypoxia-ischemia (HI) represents a major cause of brain damage in the term newborn. This study aimed to examine the short and long-term neuroprotective effect of hydrogen saline (H(2) saline) using an established neonatal HI rat pup model. Seven-day-old rat pups were subjected to left common carotid artery ligation and then 90 min hypoxia (8% oxygen at 37 degrees C). …

Hydrogen-rich pure water prevents superoxide formation in brain slices of mice

In Animal studies, Nervous system by CHESS

Hydrogen is an established anti-oxidant that prevents acute oxidative stress. To clarify the mechanism of hydrogen’s effect in the brain, we administered hydrogen-rich pure water (H(2)) to senescence marker protein-30 (SMP30)/gluconolactonase (GNL) knockout (KO) mice, which cannot synthesize vitamin C (VC), also a well-known anti-oxidant. These KO mice were divided into three groups; recipients of H(2), VC, or pure water …

Hydrogen in drinking water reduces neuronal loss in mouse model of Parkinson’s disease

In Animal studies, Nervous system by CHESS

It has been shown that molecular hydrogen (H(2)) acts as a therapeutic antioxidant and suppresses brain injury by buffering the effects of oxidative stress. Chronic oxidative stress causes neurodegenerative diseases such as Parkinson’s disease (PD). Here, we show that drinking H(2)-containing water significantly reduced the loss of dopaminergic neurons in PD model mice using both acute and chronic administration of …

Hydrogen therapy reduces neuronal apoptosis in neonatal hypoxia-ischemia rat model

In Animal studies, Nervous system by CHESS

Hypoxia-ischemia (HI) brain injury is a major cause of neuronal cell death especially apoptosis in the perinatal period. This study was designated to examine the effect of hydrogen therapy on apoptosis in an established neonatal HI rat pup model. Seven-day-old rat pups were subjected to left common carotid artery ligation and then 90 min hypoxia (8% oxygen at 37 degrees …

Hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals

In Animal studies, Nervous system by CHESS

Acute oxidative stress induced by ischemia-reperfusion or inflammation causes serious damage to tissues, and persistent oxidative stress is accepted as one of the causes of many common diseases including cancer. We show here that hydrogen (H(2)) has potential as an antioxidant in preventive and therapeutic applications. We induced acute oxidative stress in cultured cells by three independent methods. H(2) selectively …

Hydrogen gas for moderate and severe neonatal hypoxia-ischemia in rat brain

In Animal studies, Nervous system by CHESS

Hydrogen gas (H(2)) has been shown to ameliorate brain injury in experimental adult rat focal ischemia and in a mild neonatal hypoxia-ischemia (HI, 90 min hypoxia) rat model. In this study we tested H(2) in moderate (120 min hypoxia) and severe (150 min hypoxia) neonatal HI rat models. We hypothesized that H(2) would improve outcomes after neonatal HI by scavenging …

Hydrogen is neuroprotective against surgically induced brain injury

In Animal studies, Nervous system by CHESS

Neurosurgical operations cause unavoidable damage to healthy brain tissues. Direct surgical injury as well as surgically induced oxidative stress contributes to the subsequent formation of brain edema. Therefore, we tested the neuroprotective effects of hydrogen (H2) in an established surgical brain injury (SBI) model in rats. Adult male Sprague – Dawley rats (weight 300-350g) were divided into three groups to …

Drinking hydrogen water ameliorated cognitive impairment in senescence-accelerated mice

In Animal studies, Nervous system by CHESS

Hydrogen has been reported to have neuron protective effects due to its antioxidant properties, but the effects of hydrogen on cognitive impairment due to senescence-related brain alterations and the underlying mechanisms have not been characterized. In this study, authors investigated the efficacy of drinking hydrogen water for prevention of spatial memory decline and age-related brain alterations using senescence-accelerated prone mouse …
