H2HUBB TAKEAWAY
Hydrogen-bubbled platinum-colloid suppresses human esophagus- or tongue-carcinoma cells with intracellular platinum-uptake and the diminished normal-cell mortality. These findings come from a laboratory model and suggest molecular hydrogen's biological potential. Further research is needed to determine clinical relevance.
What the Researchers Tested
The study examined in vitro cell-culture laboratory experiment.
How Molecular Hydrogen Was Used
Carcinostatic effects of combined use of hydrogen nano-bubbles (nano-H) and platinum-povidone (PVP–Pt) were examined. Hydrogen-dissolved medium was prepared by hydrogen-gas bubbling with a microporous gas-emittance-terminal into a medium in the absence or presence of PVP-Pt (nano-H, nano-H/PVP-Pt). Human esophagus-derived carcinoma cells KYSE70 were repressed for cell proliferation with nano-H/PVP-Pt more markedly than with nano-H, indicating the hydrogen-intensification for PVP-Pt-alone-carcinostasis.
