Al. Dicarlo et al., A SIMPLE EXPERIMENT TO STUDY ELECTROMAGNETIC-FIELD EFFECTS - PROTECTION INDUCED BY SHORT-TERM EXPOSURES TO 60 HZ MAGNETIC-FIELDS, Bioelectromagnetics, 19(8), 1998, pp. 498-500
Stress proteins are important in protection during cardiac ischemia/re
perfusion (cessation and return of blood flow) and are reportedly indu
ced by electromagnetic (EM) fields. This suggests a possible ischemia
protection role for EM exposures. To test this, chick embryos (96 h) w
ere exposed to 60 Nz magnetic fields prior to being placed into anoxia
. Survival was 39.6% (control), and 68.7% (field-exposed). As a positi
ve control, embryos were heated prior to anoxia (57.6% survival). We c
onclude that: 1) 60 Hz magnetic held exposures reduce anoxia-induced m
ortality in chick embryos, comparable to reductions observed following
heat stress, and 2) this is a simple and rapid experiment to demonstr
ate the existence of weak EM held effects. (C) 1998 Wiley-Liss, Inc.
