It has been known for decades, that due to the mass difference between hydrogen and deuterium, the behavior of the molecules containing deuterium is altered in chemical reactions.
The difference between hydrogen and deuterium concentrations exerts a pronounced influence on the processes taking place in a given biological system. The significant effect of heavy water on the living organism is not a surprise, considering that an important part of the living body consists of water, and heavy water differs from ordinary water in many of its properties.In order to investigate whether deuterium has any role in living organisms we applied deuterium depleted water to prepare medium for tissue culture and also as drinking water to treat mice xenotransplanted with human breast tumor.
