Influence of continuous electromagnetic fields on the stage, weight and stature of the chick embryo.
The influence of continuous electromagnetic fields (0, 181 or 361 Gs/cm2) on the development of chick embryo (n = 144) was studied. Several parameters were determined at days 5, 10 and 15 of incubation: stage (following Hamburger and Hamilton), vertex-coccyx length (size) and weight. At 5 days of incubation, all embryos showed a similar stage. However, at days 10 and 15, the embryos exposed to 181 Gs/cm2 showed a stage significantly superior to that of the others. There were no differences between the exposed embryos and the control ones with regard to weight and stature, except at 15 days when the embryos exposed to 361 Gs/cm2 showed greater weight and stature than those of the controls.
