Medic Amber in a Peer-Reviewed Mobile Radiation Cell Study

Materials and methods

Dartsch Scientific studied L-929 mouse connective-tissue fibroblasts and differentiated HL-60 human leukemia-derived cells used as a neutrophil model. Cultures underwent four hours of mobile-phone and WLAN exposure.

The scratch assay measured cell migration and proliferation into a cell-free space after a further 16 hours. Other assays measured basal metabolism and induced reactive oxygen species (ROS) in the neutrophil model. Exposed cultures with Medic Amber were compared with exposed cultures without the device and unexposed controls.

Results

• Relative scratch closure was 80.1 ± 7.4% with Medic Amber and 63.6 ± 7.5% in exposed cultures without the device. Unexposed controls were normalized to 100 ± 6.5%. These are closure measurements at a fixed time, not a measurement of healing speed.
• Basal metabolism and induced ROS readouts were higher with Medic Amber than in exposed cultures without the device. Both remained below the unexposed-control values.

Study context

The experiments without Medic Amber ran first over four weeks; experiments with the device followed over three weeks. This sequence leaves time and batch differences as possible influences on the comparison. The article describes no sham device, randomization or blinding, and does not specify the phone model or radiation dose.
