TL;DR
Hydrogen-rich saline improves nerve healing and function after severe nerve injury in rats.
Key Finding
Rats treated with hydrogen-rich saline after peripheral nerve surgery showed significantly better axonal regeneration (nerve fiber regrowth) and functional motor recovery compared to control animals.
Summary
Researchers tested whether hydrogen-rich saline could help nerve healing in rats that had undergone surgery to repair a 10-millimeter gap in the sciatic nerve (a major nerve in the leg). Rats that received daily injections of hydrogen-rich saline showed better nerve fiber regrowth and improved motor function compared to rats that received regular saline, suggesting hydrogen's antioxidant (damage-fighting) properties may protect nerve tissue.
Practical Takeaway
This rat study suggests hydrogen-rich saline may support nerve healing, but it is early-stage animal research only. Before any conclusions can be drawn for human nerve injury treatment, the findings would need to be tested in human clinical trials. The study does not establish whether hydrogen water taken orally would have similar effects.
Abstract
Despite the application of nerve grafts and considerable microsurgical innovations, the functional recovery across a long peripheral nerve gap is generally partial and unsatisfactory. Thus, additional strategies are required to improve nerve regeneration across long nerve gaps. Hydrogen possesses antioxidant and anti-apoptotic properties, which could be neuroprotective in the treatment of peripheral nerve injury; however, such a possibility has not been experimentally tested in vivo. The aim of the present study was to investigate the effectiveness of hydrogen-rich saline in promoting nerve regeneration after 10-mm sciatic nerve autografting in rats. The rats were randomly divided into two groups and intraperitoneally administered a daily regimen of 5 ml/kg hydrogen-rich or normal saline. Axonal regeneration and functional recovery were assessed through a combination of behavioral analyses, electrophysiological evaluations, Fluoro-Gold™ retrograde tracings and histomorphological observations. The data showed that rats receiving hydrogen-rich saline achieved better axonal regeneration and functional recovery than those receiving normal saline. These findings indicated that hydrogen-rich saline promotes nerve regeneration across long gaps, suggesting that hydrogen-rich saline could be used as a neuroprotective agent for peripheral nerve injury therapy.
