Exposure at 20 mW/cm2 reduced creatine phosphokinase activity in embryonic quail hearts, while neither exposure level altered heart morphology or lactate dehydrogenase and glutamic-oxaloacetic transaminase activities.

Plain English Summary

Summary written for general audiences

Researchers exposed Japanese quail embryos to 2.45 GHz microwaves at 5 mW/cm2 or 20 mW/cm2 for the first 8 days of development. Neither exposure level caused changes in embryonic heart morphology or myocardial ultrastructure. Lactate dehydrogenase and glutamic-oxaloacetic transaminase activities did not differ from controls. Creatine phosphokinase activity was lower at 20 mW/cm2 compared to control, but unchanged at 5 mW/cm2.

Why This Matters

The specific absorption rates were 4.03 mW/g and 16.2 mW/g. The ambient temperature was set to maintain the eggs at 37.5°C, but thermal gradients could not be precluded. The authors concluded that 5 mW/cm2 had no effect on the developing myocardium, while 20 mW/cm2 affected cytoplasmic enzyme content.

Quick Questions About This Study

Japanese quail embryos were exposed during the first 8 days of development to 2.45 GHz microwaves at 5 mW/cm2 or 20 mW/cm2. The specific absorption rates were 4.03 mW/g and 16.2 mW/g, respectively.
Neither exposure level induced changes in the morphology of the embryonic heart or the ultrastructure of myocardial cells.
Lactate dehydrogenase and glutamic-oxaloacetic transaminase activities were not different from controls. Creatine phosphokinase activity was reduced at 20 mW/cm2 but was similar to control at 5 mW/cm2.
The data indicate that 2.45 GHz microwave irradiation at 5 mW/cm2 has no effect on the developing myocardium, while there appears to be an effect at 20 mW/cm2 on cytoplasmic enzyme content.
The ambient temperature was set to maintain the embryonated eggs at 37.5°C, though thermal gradients in the irradiated embryos could not be precluded.
