Background: Hydrogen-rich water (HRW) has been shown to be one of underlying therapeutic strategies regarding wound treatments. This study explored the effects of drinking HRW on skin wound healing in dogs. Eight circular wounds were analyzed in each dog. The experimental group was treated with HRW twice daily, while the control group was provided with distilled water (DW). The wound tissues of dogs examined histopathologically. The fibroblasts, inflammatory cell infiltration, the average number of new blood vessels, and the level of malondialdehyde (MDA) and superoxide dismutase (SOD) activity in the skin homogenate of the wound was measured using the corresponding kits. The expression of Nrf-2, HO-1, NQO-1, VEGF, and PDGF were measured by real-time fluorescence quantitative method.
Results: We observed that HRW wound had significant average healing rate and faster average healing time. Histopathological results showed that the average number of blood vessels and the average thickness of epidermis were significantly different from the DW group. The MDA levels were higher in the DW group than in the HRW group but the SOD levels were higher in the HRW group than in the DW group. The results of qRT-PCR showed that the expression of each gene was significantly different between the two groups.
Conclusions: The results showed that HRW treatment could promote skin wound healing in dogs, accelerate wound epithelization, reduce inflammatory reaction, stimulate the expression of cytokines related to wound healing, and shorten wound healing time.
