Aim of study (acc. to author)

To study the effect of a 0.05 Tesla constant magnetic field on weight gain and blood glucose homeostasis in 22 mice.

Background/further details

The mice of exposure and sham exposure groups were weighed daily for 30 days: 10 days before, 10 days during, and 10 days after exposure. After 30 days, the experimental group was again exposed to the magnetic field for 15 days. On experimental day 45, blood samples were obtained to measure blood glucose level.

Main outcome of study (acc. to author)

There was no significant difference in weight gain between exposed and sham-exposed mice. The difference between blood glucose of the exposed mice and the sham-exposed animals was also not significant.
In conclusion, the data showed that a 0.05 Tesla constant magnetic field had no impact on weight gain and blood glucose in BALB/c mice.
