[Effect of some electric signals transmitted by an induction coil on weight increase, incorporation of marker, and histological and ultrastructural appearance of the skeleton in a chick embryo].

Embryo Chicks were exposed to various types of electrical impulses transmitted by induction coils between the 6th and 13th day of incubation. Compared with controls, the Chick tibias showed a highly significant increase in weight and length as well as increased incorporation of tritiated thymidine. In addition, the total weight of the treated embryos was significantly greater than that of the controls. The results suggest that the effects of these electro-magnetic fields, particularly their skeletal effects, act principally on cellular multiplication and/or enhanced cellular activity following an increase in protein synthesis.
