Task: Question Answering
Input (English): Context: Static magnetic fields (SMF) have been widely used in research, medicine and industry. Since zinc and copper play an important role in biological systems, we studied the effects of the subchronic continuous SMF exposure on their distribution in murine tissues.', 'For 30 days, mice were exposed to inhomogeneous, vertical, downward or upward oriented SMF of 1\u2009mT averaged intensity with spatial gradient in vertical direction.', 'SMF decreased the amount of copper and zinc in liver. In brain, zinc levels were increased and copper levels were decreased. In spleen, zinc content was reduced, while copper amount remained unchanged.\Question: Does subchronic exposure to static magnetic field differently affect zinc and copper content in murine organs?
Output (English): Subchronic exposure to SMF differently affected copper and zinc content in examined organs, and the changes were more pronounced for the downward oriented field. The outcome could be attributed to the protective, rather than the harmful effect of SMF.
