  Rezumat:  This preliminary study presents the models for deuterium depletion in plant germination, mouse blood and human blood, and the application of these models to study the effect of the depleted water on the live cells. The different deuterium contents of biological fluids involved in the experiments were measured by isotopic ratio mass spectrometry. We have found that the major effect of deuterium depleted water (DDW) was the inhibition of the cell division in plants, as in animal, or in human. To study the effect of the DDW on the plant, we have measured the deuterium content of the water extracted from plants that have consumed the DDW and we have compared with the plant that have consumed the normal water. For the plant, the effect of DDW was the decrease of growing rate, and decrease of germination rate of plants. Another effect of DDW on the plants was the decrease of the average length of stem and the decrease of the average length of roots. To study the DDW effect on the animals, particularly on the mice and Wistar rats, we have watched the content of the deuterium in blood for the animals that have drunk the DDW. The experiment confirms the inhibitory effect of the DDW in tumour grows. We have found the same effect of the DDW on the human. Also, we have found that the deuterium content in the blood of the patients with cancer disease is depleted by about 5-7 ppm compared with the healthy one. We suppose that the tumorous cells that have a higher speed of growth consume the deuterium from blood . As a result, for cancerous humans the deuterium content of blood serum is diminished compared with the healthy human. We propose to use the deuterium content of the blood in the cancer diagnosis and treatment.
