TL;DR
Hydrogen treatment can reduce skin damage and speed up healing in mice after radiation therapy, but it's less effective at very high radiation doses.
Key Finding
Hydrogen injections significantly reduced the severity of radiation-induced skin damage in mice and accelerated tissue recovery after moderate-dose radiation exposure.
Summary
Researchers tested whether hydrogen could protect mouse skin from damage caused by radiation therapy. Mice received radiation to their head and neck area, with some receiving injections of hydrogen solution beforehand. Hydrogen significantly reduced skin damage severity, helped tissue heal faster, and reduced weight loss in mice exposed to moderate radiation doses, though it was less effective at the highest dose tested. The findings suggest hydrogen may help prevent radiation-induced skin injuries in cancer patients.
Practical Takeaway
This early-stage animal study suggests hydrogen may have protective potential against radiation-induced skin damage, but much more research is needed before any conclusions can be drawn for human use. The study was conducted in mice, not humans, and the protective effect appeared to depend on the radiation dose used, so effectiveness in actual cancer patients remains unknown.
Abstract
Abstract Background: Radiation therapy produced unwanted side effect on normal tissues, such as radiodermatitis. Hydrogen was previously shown capable of radiation protective in both animals and cell cultures. The effect of hydrogen was now to be investigated on radiation-induced cutaneous. Objective: Development of dermatitis is a frequent side effect of radiotherapy of patients with head-and-neck cancer. Here we analyzed the radioprotective efficacy of hydrogen under conditions of local, single dose or fractionated radiation treatment, and its possible molecular mechanisms. Methods: Mice received either single-dose or fractioned irradiation of the head-and-neck area with or without subcutaneous injection of hydrogen solution before irradiation. In vitro, the effect of hydrogen medium on radiation-induced cell viability , apoptosis and biochemical assays was measured. Result: hydrogen significantly reduced the severity of dermatitis, accelerated tissue recovery, and reduced the extent of radiation induced weight loss in mice after a single dose of 15 or 20 Gy but not 25 Gy of radiation. Hydrogen was also protective from cumulative doses of 30 Gy delivered in three fractions, respectively. Hydrogen also protect HaCaT cells from radiation-induced injury, it could significantly inhibit ionizing injury. Conclusion: These results suggest that hydrogen has a positive effect on acute radiodermatitis.
