Aim of study (acc. to author)

To characterize the influence of short-term microwave exposure (2.450 GHz) on the noradrenergic pattern and β-cardiac and α-aortic receptional functions of the rat cardiovascular system.

Main outcome of study (acc. to author)

In young and senescent animals, an increase in noradrenergic innervation was observed. Functional modification was shown in sensescent rats, but not in young rats. The results suggest that the predominant effect of microwave exposure consists in an increase in the noradrenergic pattern, and this effect is not related to the functional modifications.
