この研究は、水溶液中およびウサギ血中でのコリンエステラーゼの酵素活性に対するマイクロ波照射の直接的な影響を実験的に調べた。その結果、マイクロ波放射による影響は、温度上昇が酵素を変性させるのに十分な程度に大きいときにのみに現れることが示された、と報告している。

No direct effect of microwave exposure on the activity of acetylcholinesterase was found, neither for commercial available purified enzyme in aqueous solution nor in defibrinated rabbit blood samples. High absorbed power leads to an thermal denaturation of the enzyme in uncooled experiments and therefore causes a lack of activity.
