H2HUBB TAKEAWAY
In 22 patients with PU were recruited in the present study, hW intake via TF was demonstrated, for severely hospitalized elderly patients with PU, to execute wound size reduction and early recovery, which potently ensue from either type-I collagen construction in dermal fibroblasts or the promoted mitochondrial reducing ability and ROS repression in epidermal keratinocytes as shown by immunostain or NBT and WST-1 assays, respectively. These findings add human evidence supporting molecular hydrogen's therapeutic potential across the specific human outcomes evaluated in this study.
What the Findings Mean
H2HUBB reviewed how molecular hydrogen affected the outcomes measured in 22 patients with PU were recruited in the present study. HW intake via TF was demonstrated, for severely hospitalized elderly patients with PU, to execute wound size reduction and early recovery, which potently ensue from either type-I collagen construction in dermal fibroblasts or the promoted mitochondrial reducing ability and ROS repression in epidermal keratinocytes as shown by immunostain or NBT and WST-1 assays, respectively.
What the Researchers Studied
The researchers studied 22 patients with PU were recruited in the present study. The study used a human clinical study.
What Effects Did Molecular Hydrogen Have?
On the other hand, HW was prepared with a hydrogen-bubbling apparatus which produces HW with 0.8-1.3 ppm of dissolved hydrogen concentration (DH) and -602 mV to -583 mV of oxidation-reduction potential (ORP), in contrast to reversed osmotic ultra-pure water (RW), as the reference, with DH of < 0.018 ppm and ORP of +184 mV for use in the in vitro experimental research. HW intake via TF was demonstrated, for severely hospitalized elderly patients with PU, to execute wound size reduction and early recovery, which potently ensue from either type-I collagen construction in dermal fibroblasts or the promoted mitochondrial reducing ability and ROS repression in epidermal keratinocytes as shown by immunostain or NBT and WST-1 assays, respectively. Normal human dermal fibroblasts OUMS-36 and normal human epidermis-derived cell line HaCaT keratinocytes were examined in vitro to explore the mechanisms relating to whether hydrogen plays a role in wound-healing at the cellular level.
Why These Findings Matter
These findings add human evidence supporting molecular hydrogen's therapeutic potential across the specific human outcomes evaluated in this study and contribute to the growing body of molecular-hydrogen research.
How Strong Is This Evidence?
This is human clinical evidence from a human clinical study. H2HUBB interprets the findings in the context of the study design, sample, comparator, and measured outcomes rather than using one publication as a verdict on hydrogen therapy.
Technical Study Details
H2HUBB classifies this publication as human clinical study with human clinical evidence. The research population or model was 22 patients with PU were recruited in the present study. The reported sample size was 12. The study used a human clinical study.
Limitations and Safety
