Reversibility of microwave-induced blood-brain-barrier permeability. med./bio.

Published in: Radio Sci 1979; 14 (6) Suppl: 323-327

Aim of study (acc. to author)

The pilot investigation was performed to explore the degree of reversibility of the microwave-induced increases in brain-capillary permeability. In addition, effects of microwaves on the blood-ocular barrier were examined.

Main outcome of study (acc. to author)

Reversible increase of permeability of blood-brain barrier to horseradish peroxidase (HRP) after microwave irradiation; preliminary results obtained in two hamsters indicate that the blood-ocular barrier was similarly affected.
