H2HUBB TAKEAWAY
Hydrogen inhalation improved cough and was associated with changes in respiratory and inflammatory biomarkers among sanitation workers exposed to haze.
What the Researchers Studied
The study examined to study the protective effect of hydrogen inhalation on the lungs of sanitation workers exposed to haze.
How Molecular Hydrogen Was Used
inhaled hydrogen gas.
What the Researchers Found
(1)The FeNO levels of the treatment group (16±5)×109 were lower than those of the control group(21±14)×109 on 8th day of treatment, with significant difference(F=6.94, P 0.05). (4)The serum levels of IL-2 and SOD3 were lower in the treatment group as compared to the control group while IL-10 was higher than in the control group at each time point, and MMP-12 was lower in the treatment group than that in the control group on the 30th day(P 0.05). (5)Hydrogen inhalation improved respiratory symptoms such as cough.
H₂ Mechanisms / Biological Findings
Inhalation of hydrogen gas could alleviate airway inflammation and oxidative stress of sanitation workers exposed to air pollution.
Authors’ Conclusion
The authors concluded that inhalation of hydrogen gas could alleviate airway inflammation and oxidative stress of sanitation workers exposed to air pollution. There was even a significant inhibitory effect on the level of systemic inflammatory response. inhalation of hydrogen could improve respiratory symptoms such as cough.
