H2HUBB TAKEAWAY
In male Wistar rats, compared with those in isoproterenol-MI group, hydrogen-rich saline decreased malondialdehyde and 8-hydroxy-desoxyguanosine concentrations, enhanced superoxide dismutase and Na(+)-K(+)-ATPase activity, lowered Ca(2+)-ATPase activity and decreased interleukin-6 and tumour necrosis factor-α levels in the serum and/or cardiac tissue of rats. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.
What the Researchers Studied
Because oxidative stress plays a significant role in the pathophysiology of myocardial infarction (MI), the aim of the study was to investigate whether hydrogen-rich saline has cardioprotective effects against isoproterenol-induced MI in rats.
How Molecular Hydrogen Was Used
Different doses of hydrogen-rich saline (5, 7.5, and 10 mL/kg body weight i.p.) or Vitamin C (250 mg/kg body weight i.g.) were administered to the rats.
What the Researchers Found
Compared with those in isoproterenol-MI group, hydrogen-rich saline decreased malondialdehyde and 8-hydroxy-desoxyguanosine concentrations, enhanced superoxide dismutase and Na(+)-K(+)-ATPase activity, lowered Ca(2+)-ATPase activity and decreased interleukin-6 and tumour necrosis factor-α levels in the serum and/or cardiac tissue of rats. Hydrogen-rich saline pretreatment also diminished infarct size, improved left heart function, and ameliorated pathological changes of the left heart.
H₂ Mechanisms / Biological Findings
From these results, hydrogen-rich saline exerts cardiovascular protective effects against isoproterenol-induced MI at least in part via interactions which evoke antioxidant and anti-inflammatory activities. Infusion with hydrogen gas-saturated saline has recently been reported to exert antioxidant and anti-inflammatory activity that may protect against organ damage induced by oxidative stress. because oxidative stress plays a significant role in the pathophysiology of myocardial infarction (MI), the aim of the study was to investigate whether hydrogen-rich saline has cardioprotective effects against isoproterenol-induced MI in rats.
Authors’ Conclusion
The authors concluded that from these results, hydrogen-rich saline exerts cardiovascular protective effects against isoproterenol-induced MI at least in part via interactions which evoke antioxidant and anti-inflammatory activities.
