Abstract
As induction heating (IH) equipments are getting widely used, the intermediate-frequency magnetic fields emitted by these equipments have been attracting much attention especially from health and safety viewpoints. However, studies on microcirculation are scarce. Here, we aimed at evaluating possible effects of the magnetic field (24 kHz) emitted by an IH on isolated perfused small arteries. Mesenteric arteries (346 ± 30 μm) of Wistar rats (n = 12 for both exposure and control groups) were isolated and perfused with a vessel perfusion system (0.02 mL/min, 90 mmHg). A table-top type IH was located 250 mm apart from a vessel. Each vessel was then exposed to a magnetic field of 7.8 μT for 10 min. Inner and outer diameters were measured during and after exposure. Insignificant decreasing trends (< 1%) of vessel diameters were noticed; however, no statistically significant changes were observed compared with the control group.
