Aim of study (acc. to author)

1) To evaluate the effects of electromagnetic fields with different frequency components coming from computers, TV's, microwave ovens or hand-held cellular phones on the entry area at the front of the chest of different persons, as well as the exit area at the corresponding part of the back, or vice-versa (see "background/further details").
2) To compare the effects of microwave cooking and gas burner cooking of amino acid composition of foods.
3) To study the effects of microwaves on amino acids on the exposed and non-exposed part of the body.
4) To investigate characteristic findings of electromagnetic field induced diseases and clinical cases where intractable pain or malignant tumors appear in the cross-sectional area exposed to 2 or more electromagnetic fields coming from band-like areas under the patient's bed or coming through the wall at home.

Background/further details

Each person was seated on a chair and the center of the chest was exposed to electromagnetic fields through a square window and/or a rectangular band-shape window made on the heavy-duty aluminium foil shield.

Main outcome of study (acc. to author)

All the electromagnetic field sources not only induced the following various transitional abnormalities on the entry area, but also at the exit area on the back (but the effect lasted for a shorter time than at the entry point):
Monitor exposure of the body resulted in decrease in acetylcholine, appearance of circulatory disturbance with the appearance of thromboxane B2, short-lasting appearance of oncogene c-fos, no appearance of integrin α5β1.
Color television exposure resulted in decrease in acetylcholine, appearance of circulatory disturbance with the appearance of thromboxane B2, short-lasting appearance of oncogene c-fos, very short-lasting appearance of integrin α5β1.
Microwave exposure resulted in decrease in acetylcholine, appearance of circulatory disturbance with the appearance of thromboxane B2, short-lasting appearance of oncogene c-fos, very short-lasting appearance of integrin α5β1. Similar but less effect was found with some hand-held cellular phones.
When the aluminium foil was grounded, less of abnormality appeared even at the exposed part of the chest wall or head in all experiments. This means that prolonged, repeated exposure to electromagnetic fields without any protection may contribute to the possible development of cancer cells.
Therefore, if a strong electromagnetic field is coming from a band-shaped area under the bed to the back of the body for a prolonged period of time, then the front of the body will have an imprint of a similar abnormality.
When rice was cooked or milk was warmed by microwave oven, most of the L-amino acids changed to D-amino acids. Microwave exposure to the human induced similar amino acid changes. Thus the consumption of microwave-cooked food and exposure of the human body to microwaves over a long period of time may influence the nutritional state of the individual and may contribute to induction of cancer as well as Alzheimer's disease.
