Aim of study (according to author)
To examine the effects of mobile phone-exposure (GSM) on the early embryogenesis in japanese quails.
Four groups of fertilized eggs were examined (n=10-12 per group): 1.) control group, 38 h brooding, 2.) exposed during 38 h brooding, 3.) control group, 120 h at room temperature, then 38 h brooding (158 h in total) and 4.) exposed during 120 h at room temperature, then during 38 h brooding (158 h in total). Brooding took place in incubators (38°C). Control groups and exposure groups were brooded at the same time, however the control eggs were shielded against the electromagnetic fields by 6 layers of aluminium foil.

General category: mobile communication system, mobile phone, GSM
animal (species/strain): Japanese quail (Coturnix coturnix japonica)
whole body exposure: in ovo
investigated material: intact cell
), tissue homogenate
of whole embryo
Main outcome of study (according to author)
No malformations in the embryos occurred and no differences in the surface temperature of the eggs were found between the groups.
In the 38 hours-exposed group, a significant increased number of differentiated somites was observed in comparison to the corresponding control group. Additionally, DNA strand breaks were significantly decreased compared to the control group. An exposure for 158 hours significantly decreased the number of differentiated somites and resulted in a significant increase of DNA strand breaks compared to the control group.
The authors conclude that mobile phone-exposure can stimulate or depress the embryogenesis of Japanese quails and that this effect could depend on the exposure duration.
