What is Static Magnetic Fields Alter Arteriolar Tone in Vivo about?

## Abstract This study was designed to directly quantify the effect of localized static magnetic field (SMF) exposure on the diameter of microvessels in adult rat skeletal muscle in vivo. Microvascular networks in the exteriorized rat spinotrapezius microvasculature were exposed to a localized, uniform 70 mT SMF for 15 min. Arteriolar vessel diameters were measured; and the extent of vessel contraction, microvascular tone, was calculated before exposure, immediately after exposure, and 15 and 30 min after removal of the field. A calculated value of high tone corresponds to vessels that are vasoconstricted and a calculated value of low tone refers to vessels that are vasodilated. Vessels with initial tone 15% showed a significant (__P__ < 0.05) decrease in tone 15 and 30 min following application, respectively. Further classification of the data with regards to the initial vessel diameter demonstrated that vessels with initial diameters <30 μm and initial tone <15%, smaller diameter vessels that are initially vasodilated, showed significant (__P__ < 0.05) increase in tone immediately, 15 and 30 min following SMF exposure. Additionally, 15% initial tone, smaller diameter vessels th
