Effect of magnetic fields on membrane associated enzymes in chicken embryos, permanent or transient?
Exposure to a 60Hz, 4 microT electromagnetic field resulted in a significant reduction in the activity level of 5' nucleotidase in normal live embryos. Levels of acetylcholinesterase and alkaline phosphatase were not affected. The effect of the field on 5'NT levels appears to be permanent, as incubation in a field free environment for a further 15 days did not result in enzyme levels returning to control values.
