The usual concentration of deuterium in water is about 144 ppm D/(D+H). It is known that the increase of deuterium in the body of living animals is a naturally bioaccumulation process and could be enhanced by adding in their diet heavy water – with obviously dramatically changes in health state.
The aim of this study was to investigate the effect of DDW over experimental Walker tumors inducted at Wistar rats and how far can influence the decrease of deuterium’s value at treated animals. The result shows that DDW has a significant effect over the sub epidermal tumors and it has no side effects.
The deuterium’s analyses results show that DDW’s rate of depletion is in correlation with a couple of factors (the concentration of deuterium depleting agent; the period of administration of deuterium depleting agent).
