H2HUBB TAKEAWAY
In mice, therapy with 2% H₂ increased the survival rate, alleviated the injuries caused by oxidative stress and inflammation, reduced HMGB1 levels but increased HO-1 levels in WT septic mice, but not in Nrf2-KO mice. 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 molecular hydrogen affected the outcomes measured in mice. Therapy with 2% H₂ increased the survival rate, alleviated the injuries caused by oxidative stress and inflammation, reduced HMGB1 levels but increased HO-1 levels in WT septic mice, but not in Nrf2-KO mice.
What the Researchers Studied
The researchers studied mice. The study used a preclinical animal experiment.
What Effects Did Molecular Hydrogen Have?
2% inhaled H₂ concentration. Therapy with 2% H₂ increased the survival rate, alleviated the injuries caused by oxidative stress and inflammation, reduced HMGB1 levels but increased HO-1 levels in WT septic mice, but not in Nrf2-KO mice. Hydrogen gas (H₂), which has anti-oxidative, anti-inflammatory, and anti-apoptotic effects, can be effectively used to treat septic mice.
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.
Technical Study Details
H2HUBB classifies this publication as animal study with preclinical animal evidence. The research population or model was mice. The study used a preclinical animal experiment. The reported hydrogen concentration was 2% inhaled H₂ concentration.
Limitations and Safety
