Abstract

Brief exposure to moderate intensity static magnetic fields has been shown to produce a transient alteration in physiological function in a variety of biological systems, primarily those related to changes in intracellular Ca²⁺. In the present study GH3 cells were cultured during continuous exposure to a 0.5 T field, for periods of up to 5 weeks. Following a 1-week exposure, cell growth declined by 22% and returned to control levels in 1 week. This was not statistically significant but, with a 4-week exposure, a statistically significant decline in growth of 51% was observed and return to control levels did not occur for 4 weeks. Cell diameter, on the other hand, significantly increased following 3 weeks of exposure and did not return to control levels for 3 weeks after termination of exposure. Ca²⁺-dependent changes in the dynamic reorganization of the actin cytoskeleton are suggested as the probable explanation for these observations.

Paraquat/BBB

Dear Mr DeJesus,

With interest I read the abstract of your co-authored study "Paraquat is excluded by the blood brain barrier in rhesus macaque: An in vivo pet study".

I suffer from Multiple Chemcial Sensitivity (MCS), a condition in which a permanently broken down blood-brain barrier (BBB) has been found, according to the German researcher Bodo Kuklinski. When I had a loading with paraquat I remember a number of neurological and psychological symptoms, severe headaches, irritability loss of short term memory, complete lack of any dream recollection were among them. People with MCS have a high risk of Parkinson disease.

Are you aware of the research into electromagentic fields, especially microwave effects on the BBB? A number of Swedish researchers, Salford, Bertil and Persson have publisehd a number of studies that showed a permeated BBB and leaking of albumin.

Would you consider repeating your study under conditions of microwave exposure that has become common for a high percentage of the population in the western world?
