Abstract

The biological effects of magnetic fields are known to be realized through the water structure of living organisms, which is the 60-90% of cells. In this respect the experiments investigating the magnetosensitivity of different tissues of rats by measuring the changes of hydration are of great interest. As it was shown, the tissues with higher hydration state (brain) were more sensitive to SMF influence, where depending on the exposure time the hydration of brain tissue increased. The hydration of the liver tissue, which was initially the least, was not changed.

Main findings

In rat tissues exposed to a permanent/static magnetic field (SMF), brain tissue (described as having higher initial hydration) was reported to be more sensitive, with brain hydration increasing depending on exposure time. Liver tissue hydration (described as initially the least hydrated) was reported as unchanged.

Outcomes measured

  • Tissue hydration changes (brain, liver)

Limitations

  • No sample size reported in abstract
  • Exposure characteristics (field strength, duration details) not specified in abstract
  • Outcome limited to hydration measures; broader biological/health endpoints not described
