Negative Air Ion (5)


昨日に引き続き、大気電気系の専門家であるNiels Jonassenによる概論の5回目:

Unipolar Ionized Air

A few years ago, I was contacted by a Danish architect; let us call him Mr. W. He was very interested in indoor climate and wanted to learn more about ions and their effects on people. Of course, I told him that ions had no (direct) effect on people, but sure, I could teach him something about ionizers for air-cleaning purposes and for neutralizing charges on insulators.


Mr. W believed in the healing effects of (negative) ions. He used unipolar ionizers for treating patients suffering from various ailments and reported surprisingly positive results. I insisted that it was not the ions but their charge that was responsible for any effects. After some pilot laboratory experiments, it was demonstrated that positive and negative ions were equally effective. The flow of unipolar ionized air seemed to be especially effective in healing sores and wounds and in reducing (and not only temporarily) pains and side effects in, for example, cancer patients undergoing chemotherapy or radiation treatment. Mr. W also had some ideas that the method actually was a kind of acupuncture, but in any event, it was definitely an alternative method of treatment.


In the Western world, or at least in Denmark, the established medical society frowns on anything alternative, especially if it contains elements of sciences of which the established medical society has no knowledge and experience - such as physics. So there was no way that Mr. W could have a clinical test of his method performed in Denmark under proper medical supervision. However, in other parts of the world, the attitude to alternative treatment methods is quite different.


At the prestigious Chulalongkorn University Hospital in Bangkok, where acupuncture is a recognized specialty, the chief oncologist, Kris Chatamra, had heard about Mr. W's results and offered to set up a small pilot project as a forerunner for a proper clinical test. The pilot project was conducted in June 2002. Chatamra had chosen four very sick patients for the test: three cancer cases (considered terminally ill) and one patient with a chronic infection (diabetes related) on one foot. All four patients were in severe pain and required regular and strong analgesia.

バンコックで評価の高いChulalongkorn University Hospitalでは鍼が専門として認めらており、そこの腫瘍学者の長であるKris ChaamraがミスターWの結果について聞いて、正式な臨床試験の前の小規模パイロットプロジェクトの実施を申し出た。パイロットプロジェクトは2002年6月に実施された。Chatamraはこの実験のために症状の重い患者を4人選んだ。3人の癌患者は末期症状と見られていて、あと一人の患者は糖尿病に関連した片足の慢性の患者だった。4人とも激痛で、規則的に鎮痛剤が必要だった。

The patient to be treated was placed on an insulative sheet on a cot, and a wrist or ankle strap was attached to the patient. A flow of unipolar ionized air was directed toward a selected exposed part of the patient's skin. The strap connected the patient to the ionizing unit through a feedback system, which monitored the ion flow and the total dose. The current to the patient was in the order of μA, and the exposure time was typically 90 minutes. The length of the trial was 10 days. The patients were fully assessed prior to the trial and also assessed daily during the trial by a specialist nurse. Pain assessment was conducted by patient scoring and by the amount of analgesia required daily.

治療される患者はベッドの絶縁のシーツに置かれ、手首または足首ストラップが患者に付けられた。単極 イオン化された空気の流れは、患者 の皮膚の選ばれた露出部分に向けられた。ストラップはフィードバック・システ ムによって患者をイオン化しているユニットに接続された。そして、イオンの流れと、総量をモニタした。 患者への電流はμAオーダーで、露出時間は典型的には90分だった。実験期間は10日間だった。患者たちは実験前に完全に診断され、実験中は専門看護婦によって評価された。痛みの評価は患者自身によるスコアリングと日々に必要とした鎮痛剤の量により、計測された。

At the end of the pilot project, Chatamra concluded: 
The results are encouraging: All patients required less analgesia (one patient actually stopped taking it altogether). The chronic wound also showed accelerated healing, and the patient is now discharged from the surgical unit. None of the patients suffered any complications.


This was a very small project. It did not prove anything, scientifically speaking. But as Chatamra says, the results are encouraging. A proper clinical test with all the necessary precautions, such as double-blind testing and the use of a control group, is planned.


My role in the pilot project, and maybe in the (hopefully upcoming) clinical test, has merely been that of a physics consultant and observer - an observer who has gradually lost his belief that ions have no effect on human beings. However, to quote Luke 15:7, "There will be more rejoicing in heaven over one sinner who repents." Still, the negative-ion myth and the ion-balance myth are nothing but that, myths.

パイロットプロジェクトおよび今後実施されるだろう臨床試験における私の役割は、単に物理学コンサルタントおよびオブザーバーである。イオンが人間に影響を及ぼさないと いう彼の確信を徐々に失いつつあるオブザーバーとして。しかし、ルカによる福音書15章17節を引用しておくと「言っておくが、このように、悔い改める一人の罪人については、悔い改める必要のない九十九人の正しい人についてよりも大きな喜びが天にある」 それでも陰イオン神話とイオンバランス神話は神話に過ぎない。

Niels Jonassen, MSc, DSc, worked for 40 years at the Technical University of Denmark, where he conducted classes in electromagnetism, static and atmospheric electricity, airborne radioactivity, and indoor climate. After retiring, he divided his time among the laboratory, his home, and Thailand, writing on static electricity topics and pursuing cooking classes. He passed away in 2006.
