TL;DR
Using a special heavy water solution for cold storage and treating with hydrogen gas after reperfusion can together better protect rat livers from damage during transplantation.
Key Finding
Combining heavy water-containing solution during storage with hydrogen gas treatment after reperfusion provided additive protective effects against liver injury in rat livers, outperforming conventional preservation methods alone.
Summary
Researchers tested whether combining two preservation techniques could better protect rat livers during transplantation. They stored livers in a special solution containing heavy water for 48 hours, then treated them with hydrogen gas after blood flow was restored. The combination approach reduced liver damage markers and improved liver function better than either treatment alone or standard preservation methods.
Practical Takeaway
This is an early-stage animal study on organ preservation for transplantation, not on hydrogen water for human consumption. While the results suggest hydrogen gas may help protect organs during transplant procedures, this finding does not translate directly to health benefits from drinking hydrogen water. Much more research, including human studies, would be needed before any clinical applications could be considered.
Abstract
We previously reported the efficacy of cold storage (CS) using a heavy water-containing solution (Dsol) and post-reperfusion hydrogen gas treatment separately. This study aimed to clarify the combined effects of these treatments. Rat livers were subjected to 48-hour CS and a subsequent 90-minute reperfusion in an isolated perfused rat liver system. The experimental groups were the immediately reperfused control group (CT), the CS with University of Wisconsin solution (UW) group, the CS with Dsol group, the CS with UW and post-reperfusion H2 treatment group (UW-H2), and the CS with Dsol and post-reperfusion H2 group (Dsol-H2). We first compared the Dsol-H2, UW, and CT groups to evaluate this alternative method to conventional CS. The protective potential of the Dsol-H2 group was superior to that of the UW group, as evidenced by lower portal venous resistance and lactate dehydrogenase leakage, a higher oxygen consumption rate, and increased bile production. Multiple comparison tests among the UW, Dsol, UW-H2, and Dsol-H2 groups revealed that both treatments, during CS and after reperfusion, conferred a similar extent of protection and showed additive effects in combination therapy. Furthermore, the variance in all treatment groups appeared smaller than that in the no-treatment or no-stress groups, with excellent reproducibility. In conclusion, combination therapy with Dsol during CS and hydrogen gas after reperfusion additively protects against graft injury.
