Abstract:
Objective: We aimed to show the short- and long-term protective effects of inhaled hydrogen gas on renal ischemia/reperfusion (I/R) injury in a rat model. Material and
Methods: Thirty Sprague-Dawley rats were randomly divided into 3 major experimental groups (Group 1, sham; Group 2, I/R; Group 3, hydrogen-I/R). Subsequently, Group 2 and 3 were divided into subgroups as early (E) and late (L) periods. Group 2 and 3 underwent 45 minutes of renal ischemia.Group 3 was administered 182.5 min (175-185 min) 2% hydrogen gas (2 L/min) in total (1 h before ischemia, by ischemia period and 1 h after reperfusion). Left nephrectomy was performed 6 hours after reperfusion in the early groups and at the 14th day of reperfusion in the late groups. We performed histopathological examination.
Results: Kidneys from control rats (Group 2) exhibit significant injury characterized by marked histological changes characteristic of I/R injury in the outer medulla and cortex regions. Histological alterations were markedly reduced and all histological scores for renal injury were significantly lower in specimens from the hydrogen-I/R group compared to the control group (p=0.001).
Conclusion: In this study, we demonstrated that hydrogen gas significantly attenuated renal I/R injury in early and late periods, and may have therapeutic potential against various clinical conditions involving I/R injury.

Molecular hydrogen: prospective treatment strategy of kidney damage after cardiac surgery
2023 - Kidney - Surgery/Transplantation
Cardiac surgery-associated acute kidney injury (CS-AKI) is a common postoperative complication, mostly due increasing oxidative stress. Recently, molecular hydrogen (H2 gas), has also been applied to cardiac surgery due to its ability to reduce ...

2023 - Kidney - Acute Kidney Injury
Acute kidney injury (AKI) is the major complication of rhabdomyolysis (RM) clinically, which is usually mimicked by glycerol injection in basic research. Oxidative stress, inflammatory response and apoptosis are recognized to play important roles in ...
Hydrogen attenuates endothelial glycocalyx damage associated with partial cardiopulmonary bypass in ...
2023 - Endothelium - Surgery/Transplantation
Cardiopulmonary bypass (CPB) causes systemic inflammation and endothelial glycocalyx damage. Hydrogen has anti-oxidant and anti-inflammatory properties; therefore, we hypothesized that hydrogen would alleviate endothelial glycocalyx damage caused by ...
Hydrogen Attenuates Inflammation by Inducing Early M2 Macrophage Polarization in Skin Wound Healing
2023 - Skin - Surgery/Transplantation
The heterogeneous and highly plastic cell populations of macrophages are important mediators of cellular responses during all stages of wound healing, especially in the inflammatory stage. Molecular hydrogen (H2), which has potent antioxidant and ...
Hydrogen-generating Si-based agent improves fat graft survival in rats
2023 - Skin - Surgery/Transplantation
Background: Regulating excessive inflammation and oxidative stress in fat grafting may improve retention rates. Hydrogen effectively combats oxidative stress and inflammation and reportedly inhibits ischemia-reperfusion injury in various organs. ...
