  "main_findings": "After 30 minutes of in vivo exposure of white male rats to a constant static magnetic field (SMF) of 0.2 T, dehydration was detected in brain, kidney, and liver tissues. Ouabain binding at 5×10^-9 M decreased in brain, heart, spleen, and liver tissues and increased in kidney tissue; with longer exposure, dehydration of the whole organism was observed.",
