The respective actions of N-pole and S-pole of 2 kinds of permanent magnets of different gauss on the peripheral circulatory kinetics of the hamster's buccal pouch were determined by the laser doppler flowmeter (LDF), and the following conclusions were obtained:
1) Cylindrical N-pole of 15 mm-diameter and 7 mm-height of a magnet of 1200 gauss caused an increase in blood flow of 0.44±0.07 V compared with a decrease of -0.37±0.05 V for S-pole.
2) Cylindrical N-pole of 9 mm-diameter and 7 mm-height of the same magnet caused an increase in blood flow of 0.20±0.03 V, parallel to that of 0.19±0.03 V for S-pole.
The above results confirmed that a permanent magnet of a constant gauss N-pole caused increased blood flow regardless of its magnitude but S-pole caused an alternation of increase and decrease according to its magnitude. It was also proved that the action of the magnet applied was exerted immediately upon the blood flow and kept this constant regardless of time, and returned to original values immediately after stopping.
