H2HUBB TAKEAWAY
In mice, however, H₂ did not substantially affect the H/R-induced increase in erythropoietin or pulmonary artery remodeling. These results are preclinical and suggest that molecular hydrogen did not improve the measured outcome. Further human research is needed to determine its clinical relevance.
What the Researchers Studied
The study examined mice.
How Molecular Hydrogen Was Used
Molecular hydrogen was administered as here the researchers investigated whether hydrogen can protect the lung from chronic injury induced by hypoxia/re-oxygenation (h/r). h₂ attenuated h/r-induced production of hydroxyl radicals, up-regulation of colony-stimulating factors, and recruitment of neutrophils and m1 macrophages to lung tissues. however, h₂ did not substantially affect the h/r-induced increase in erythropoietin or pulmonary artery remodeling.
What the Researchers Found
However, H₂ did not substantially affect the H/R-induced increase in erythropoietin or pulmonary artery remodeling.
H₂ Mechanisms / Biological Findings
The source material reviewed did not establish a specific molecular hydrogen mechanism for the reported findings.
Authors’ Conclusion
The authors concluded that H₂ ameliorates H/R-induced lung injury by inhibiting hydroxyl radical production and inflammation in lungs.
