日前午馬先生因為肺癌過世，心中感到非常難過，科學的進程總是非常緩慢。
中國時報 <癌症大浪來襲>2月4日為世界癌症日。世界衛生組織（WHO）發表報告預測，未來20年，全球癌症將激增57％，並警告說目前全球正面臨癌症的「大浪潮」，癌症已成為迫在眉睫的「人類災難」。根據WHO癌症專家，新的癌症病例將在未來20年內，由2012年的1400萬個上升到2200萬個。而在同一期間內，癌症死亡人數也將由每年820萬人之間，升高到每年1300萬。
看到這樣的報導總是讓人心驚。我希望科學的速度可以加快，能夠找出低抗癌症真正有效的方法。我司長期研究的除了氫水，還有低氘水。為何要研究低氘水，因為我們認為這仍是目前就我們所知抵抗癌症最有機會的物質。
近日與一位老友重逢，但他已經得了癌症已到末期，他也已放棄治療，我雖提供氫水給他，也使他得到較好的舒緩，但我一再強調，氫水並不治療癌症，而是在使癌症患者的正常細胞較不易死亡，抗癌的能力也較強。但這位老友(他是一位名人 我就不提他的名字)的情況確實頗為嚴重了，心中不忍，還是自羅馬尼亞為他進口低氘水，希望能對他有幫助。
氘是氫的同位素，因為水是H2O，所以自然界的水中也都含有氘，約有150ppm。要講科學原理很多人看不懂，所以下面的文章請自己慢慢看。我用最簡單的方式來說，我們喝的水當中含有150ppm以上的氘。而科學研究，氘與癌細胞的分裂相關，這個150ppm存在水中的氘，也就表示，我們的體液中也含有150ppm的氘。這個濃度的環境利於癌細胞的分裂。但假設，將水中的氘拿出來(這很困難，需要高度的科技)。取出一部份的氘，這水就是低氘水。不可能取出全部的氘，所以低氘水有分為25ppm 50ppm 75ppm及100ppm等規格。如果癌症病人常期喝低氘水(只能喝低氘水不喝別的水)，那麼這位病人的體液中的氘就會降低。這時候低於150ppm的體液，就成為不利癌細胞分裂的環境。這時，癌細胞因為無法分裂而逐漸死亡(細胞每三個月會死掉)。
這一段說法希望有助您理解。
氘這個字看起來很可怕，是的，純氘氣是一種化學武器，科學家發現濃度高的氘可以使人在幾個小時內長出腫瘤。
所以反之，濃度低的氘也就可以讓腫瘤無法分裂與生長。
低氘水也就是一般的水，只是拿走了不好的物質–氘。它是完全無毒沒有害的。一般正常的人也可以喝，只是因為很貴，所以還是癌症患者喝較好。
低氘水可以用寶特瓶裝，也可以加熱。泡茶煮湯都無妨。氫水是在純水中加入氫氣，只能用玻璃瓶裝，也不可以加熱。但這兩種水對健康都有幫助。
低氘水
低氘水，英文名depleted deuterium water，簡稱DDW。
自然界裡存在的水一般由2個氫原子和1個氧原子組成，但氫原子有品質不同的3個同位素，原子量量分別為1，2，3的氫（H）、氘（D ,重氫）、氚（超重氫）。自然界的水中，重氫的含量約為150ppm，由D代替H結合的水就是重水。國內外研究表明，重氫對生命體的生存發展和繁衍有害。低氘水對人體健康有諸多好處，更有益於生命體的生存和繁衍，對於人類的健康具有重要意義。
在地球上一切自然水體中都含有氫的同位素氘（Dao），不管氘含量多少，對生物體都是有害的，水中正常的氘含量雖沒有引起明顯的危害性，但只要正常的水中稍微脫去一部分氘，對人體健康的作用都無法估量，所以越來越多的人選擇了低氘水。
俄羅斯醫學科學院癌症科研所與俄羅斯科學院醫學生物問題研究所通過對動物的實驗發現，長期飲用氘含量低的水可抑制動物惡性腫瘤的發展，並延長動物的壽命。
氘水
氘為氫的一種穩定形態同位素，也被稱為重水，通常媒體常提到的原子能核電站或製造原子彈的所謂重水反應堆，用的重水就是氘水。
氘的存在對於細胞分裂的意義重大，D/H（氘/氫）比例的變化能引發細胞分裂。當病患飲用正常氘濃度的水時，D/H的存在比例能滿足腫瘤細胞的分裂條件。而當我們通過飲用低氘水來降低體內D/H的存在比例時，適宜於腫瘤細胞分裂的環境便不復存在；或者說，要再次達到滿足腫瘤細胞分裂所需的D/H比例，需經過很長的時間恢復。通過飲用低氘水，我們剝奪了腫瘤細胞分裂的適宜環境，從而達到抑制腫瘤的目的。
The usual natural water consists of nine stable isotope connections
1H216O, 1H217O, 1H218O,
2D216O, 2D217O, 2D218O,
1H 16O 2D, 1H 17O 2D, 1H 18O 2D
in which there are two stable isotopes of hydrogen – protium (1H) and deuterium (2D). Taking into account a radioactive isotope of hydrogen – tritium (3T ) – the common number of isotope variants of water will be equal to 27.
Water Isotope Standards
D/H = (155,76 ± 0,5) × 10-6 or ≈ 156 ppm
18O/16O = (2005,2 ± 4,5) × 10-6 or ≈ 2005 ppm
D/H = (124,6 ± 0,5) × 10-6 or ≈ 124,5 ppm
D/H = (90,5 ± 1,0) × 10-6 or ≈ 90,5 ppm
Physical-Chemical Properties of Heavy Water
http://www.o8ode.ru/article/oleg/tagelaa_voda_i_gizn.htm
It’s well known that physical-chemical properties of heavy water are totally different from properties of usual water: boiling temperature of heavy water is +101,4°С, the freezing point equals to +3,81°С and it has 10% higher density.
Need to note, that heavy water is probably fully Earth born product – in outer space it was not registered. Deuterium is formed from protium after it captured neutron from cosmic radiation. World Ocean, polar and mountain ice, atmospheric moisture are the main “factories” of deuterium production.
Density vs. temperature dependence for usual and heavy water
When autumn comes to northern regions, the water in rivers began cooling down. This process is accelerated under influence of permafrost and at the same time. Finally the water density reaches its maximum value – at temperature slightly below 4oC. This is a critical moment while after it in some areas of the bottom zone loose underwater ice is intensively formed.
Unlike normal ice, it has no regular crystal lattice, it has a different structure. The crystallization centers of this ice can be rocks, snags, and various irregularities, not necessarily lying on the bottom and associated with permafrost. The loose ice is formed in deep rivers with calm laminar flow.
The underwater ice formation usually ends with the ice float to the surface, although at this time no other ice around. Underwater ice sometimes can be seen even in summer. The question arises: what kind of “water” is in the water, which changes its aggregate state when temperature in the river is too high to turn ordinary water into ice, so that, as physicists say, there was a phase transition?
It’s well known that loose frazil ice appears first and melts last. We can assume that loose ice has higher concentration of heavy water than usual ice. Only the presence of such concentrations may explain the proven fact that in winter in northern waters the percentage of deuterium is noticeably reduced. Polar waters, as it is shown by tests, are with low deuterium concentration too. Moreover, the tests have proved that the ice as well as ice cover in high latitudes have higher deuterium content than the waters around them.
Need to remember that heavy water is indistinguishable from normal, but its consumption inside the organism can cause severe poisoning. By the way, local people in high-latitude regions do not use river ice for cooking – only lake ice or snow.
Light water production methods
Heavy water is traditionally produced by using electrolysis of NaOH or KOH solutions. Usually from solution is used 25% of water and the received hydrogen is burned catalytically into water. The received light water is used to make a new solution and the electrolysis is performed second time. This electrolysis method with a separation factor of 8 can decrease the deuterium content in the produced hydrogen so much that after second stage in the obtained water the heavy water content is below 1 ppm. (see in J. Am. Chem. Soc., 1935, 57 (3), pp 484–486; http://pubs.acs.org/doi/abs/10.1021/ja01306a027)

It must be noted, that actually the interest of separating water into heavy and light fractions was mainly connoted with production of heavy water fraction, so the main methods in here were developed for that purpose. Light hydrogen gas, released during electrolysis, was always considered as a by-product.
Light hydrogen (with low deuterium content) can be produced also using sodium amalgam:
Na + nH2O ) Na+ + OH- + 1/2H2 + (n – 1)H2O
During this reaction in the released gaseous hydrogen deuterium content is below 50 ppm (see in Ind. Eng. Chem. Res. 1999, 38, 2425-2427; http://pubs.acs.org/doi/abs/10.1021/ie9807248 ). The authors of this research consider their method as a perspective one for large scale production of light water.
At present a new electrolysis based method is developed which is allowing decrease the deuterium content in the water 5 times (see article: Y. Sinyak et. al, Acta Astronautica 52, 2003, pp.575 – 580 ). This technology was developed by the Institute of Medical and Biological Studies of the Russian Academy of Sciences for producing deuterium-free drinking water for Mars mission spaceship crew.
In 1930’s some laboratories already began conducting biological studies with light water. However the turning point in this area can be considered the first detailed studies on serious role of light and heavy water on growth of cells. These studies were conducted in Hungary by Dr. Gabor Somalyai. After their first report of experimental results (see Somlyai, et al., Naturally occurring deuterium is essential for the normal growth rate of cells. FEBS Lett. 1993, 317, 1-4) the interest in using light water for medical purposes increased drastically and at present light water production in realized in commercial quantities
