TL;DR
Injecting hydrogen saline into rats after a stroke reduces brain damage and improves recovery.
Key Finding
Hydrogen saline administered within 6 hours after a stroke reduced brain damage, swelling, and improved neurological function in rats by decreasing oxidative stress and inflammation.
Summary
Researchers tested hydrogen saline (a salt solution containing dissolved hydrogen gas) in rats that had a stroke caused by blocked blood flow to the brain. When given within 6 hours after the stroke, hydrogen saline reduced brain damage, swelling, and improved neurological function by decreasing harmful molecules (oxidative stress) and inflammation in the brain.
Practical Takeaway
This early-stage animal study suggests hydrogen saline may have potential as a stroke treatment, but it is a rat study only and does not yet demonstrate effects in humans. Much more research, including human trials, would be needed before any clinical recommendations could be made.
Abstract (excerpt)
Hydrogen gas is neuroprotective in cerebral ischemia animal models. In this study, we tested the neuroprotective effects of hydrogen saline, which is safe and easy to use clinically, in a rat model of middle cerebral artery occlusion (MCAO). Sprague-Dawley male rats weighting 250-280 g were divided…
