H2HUBB TAKEAWAY
In For human ex vivo studies, the researchers collected blood samples from six healthy humans and added normal saline or hydrogen-rich saline to blood and platelet-rich plasma, collagen-induced platelet aggregation was significantly decreased in H₂ gas and HS group rats (p=0.042, 0.018, respectively), while there was no difference in non-H₂ gas and NS group rats before and after treatment. The authors concluded that in summary, these data suggest that hydrogen may inhibit collagen-induced platelet aggregation. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
What the Findings Mean
H2HUBB reviewed how inhaled hydrogen gas affected the outcomes measured in For human ex vivo studies, the researchers collected blood samples from six healthy humans and added normal saline or hydrogen-rich saline to blood and platelet-rich plasma. Collagen-induced platelet aggregation was significantly decreased in H₂ gas and HS group rats (p=0.042, 0.018, respectively), while there was no difference in non-H₂ gas and NS group rats before and after treatment.
What the Researchers Studied
The researchers studied For human ex vivo studies, the researchers collected blood samples from six healthy humans and added normal saline or hydrogen-rich saline to blood and platelet-rich plasma. The study used a laboratory experiment.
What Effects Did Molecular Hydrogen Have?
Source-reported hydrogen concentration: 1.3% source-reported H₂ gas concentration; Source-reported hydrogen exposure: 1.3% source-reported H₂ gas concentration; reported treatment duration: 3 hours. Collagen-induced platelet aggregation was significantly decreased in H₂ gas and HS group rats (p=0.042, 0.018, respectively), while there was no difference in non-H₂ gas and NS group rats before and after treatment. The authors concluded that in summary, these data suggest that hydrogen may inhibit collagen-induced platelet aggregation. Hydrogen can selectively re- duce the levels of hydroxyl radicals ( OH) and peroxynitrite (ONOO – ), which are strong oxidative reactive oxygen spe- cies (ROS) that react indiscriminately with nucleic acids, lipids, and proteins, thus resulting in DNA fragmentation, lipid peroxidation, and protein inactivation (2). Sev- eral other studies have also demonstrated similar protective effects of hydrogen in ischemia-reperfusion injuries caused by oxidative stress in the brain, liver, heart, and intes- tines (4-8).
Why These Findings Matter
These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
How Strong Is This Evidence?
This is laboratory evidence from a laboratory experiment. It is most informative for the biological mechanisms, cellular responses, or biochemical outcomes directly measured.
Technical Study Details
H2HUBB classifies this publication as laboratory study with laboratory or cellular evidence. The research population or model was For human ex vivo studies, the researchers collected blood samples from six healthy humans and added normal saline or hydrogen-rich saline to blood and platelet-rich plasma. The study used a laboratory experiment. The hydrogen delivery method was inhaled hydrogen gas. The source-reported hydrogen concentration was 1.3% source-reported H₂ gas concentration. The reported treatment duration was 3 hours.
