H2HUBB TAKEAWAY
In cultured tumor cells, hydrogen-rich water combined with platinum colloid showed greater antitumor activity than hydrogen-rich water alone and was associated with apoptosis-like cell changes. 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
The researchers showed that hydrogen water erased ROS indispensable for tumor cell growth by ESR/spin trap, the redox indicator CDCFH-DA assay, and was cytotoxic to Ehrlich ascites tumor cells as assessed by WST-8 assay, crystal violet dye stain and scanning electron microscopy, after 24-h or 48-h incubation sequent to warming at 37°C or 42°C. Hydrogen water supplemented with platinum colloid (0.3 ppm Pt in 4% polyvinylpyrrolidone) had more antitumor activity than hydrogen water alone, mineral water alone (15.6%), hydrogen water plus mineral water, or platinum colloid alone as observed by decreased cell numbers, cell shrinkage and pycnosis (nuclear condensation)/karyorrhexis (nuclear fragmentation) indicative of apoptosis, together with cell deformation and disappearance of microvilli on the membrane surface.
