H2HUBB TAKEAWAY
In Sprague-Dawley rats, a reduction of the blood glucose level from 500+/-32.51 to 366+/-68.22 mg/dl at 4 h after dextrose injection was observed in hydrogen treated animals. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
What the Findings Mean
H2HUBB reviewed how inhaled hydrogen gas affected the outcomes measured in Sprague-Dawley rats. A reduction of the blood glucose level from 500+/-32.51 to 366+/-68.22 mg/dl at 4 h after dextrose injection was observed in hydrogen treated animals.
What the Researchers Studied
The researchers studied Sprague-Dawley rats. The study used a preclinical animal experiment. The comparison condition was control condition or baseline measurements.
What Effects Did Molecular Hydrogen Have?
Reported treatment duration: 2 hr. A reduction of the blood glucose level from 500+/-32.51 to 366+/-68.22 mg/dl at 4 h after dextrose injection was observed in hydrogen treated animals. The authors concluded that in conclusion, hydrogen gas reduced brain infarction, hemorrhagic transformation, and improved neurological function in rats. The potential mechanisms of decreased oxidative stress and glucose levels after hydrogen treatment warrant further investigation. One unexpected result from this study is that hydrogen reduced, even though only transiently at 4 hr after ischemia, glucose levels and this observation may indicate other mechanisms may be involved in the neuroprotection by hydrogen in addition to the existing mechanisms that hydrogen reduced DNA damage and lipid peroxidation which were also shown by this study from 8OHG and HNE experiments.
Why These Findings Matter
These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
How Strong Is This Evidence?
This is preclinical animal evidence from a preclinical animal experiment. It is most informative for the disease model, mechanisms, biomarkers, and outcomes directly measured in the study.
