The aim of this study was to evaluate the influence of magnetic field exposure on the blood-brain barrier permeability in diabetic rats in contrast to normoglycemic rats.
| Exposure | Parameters |
|---|---|
|
Exposure 1:
50 Hz
Exposure duration:
repeated daily exposure, 8 h/day for 21 consecutive days
|
The experiment included 4 groups: group 1 (n=8) served as control, group 2 (n=8) normoglycemic + 50 Hz magnetic field, group 3 (n=8) diabetes mellitus and group 4 (n=12) diabetes mellitus + 50 Hz magnetic field.

| Distance between exposed object and exposure source | 0.012 m |
| Setup | Animals from group 2 and 4 were injected with 65 mg/kg streptozotocin and were placed in cages which were placed above the coils. Animals from group 1 and 3 were held in the same conditions but the coils were not connected to the electric supply. |

The findings of this study suggest that magnetic field has no effect on the blood-brain barrier permeability in normoglycemic animals. However, diabetic rats are vulnerable to magnetic fields.
