Changes in the Cardiovascular System of Rabbits Subjected Continuously to a Static Magnetic Field of 600 Oe

摘要

Cardiovascular changes were investigated in domestic white rabbits (3 to 3.5 kg) following a 5-wk exposure to a static magnetic field of 600 Oe. The animals were exposed in a room at 24 +- 1 exp 0 C, 60 +- 5% relative humidity that was lit from 0600 to 1800 hr. The 6 experimental and 4 control rabbits were injected intramuscularly with 1 mg/kg Reserpine 24 hr prior to measurement of magnetic field effects to suppress reaction to external stimuli. Rabbits exposed to the magnetic field for a comparatively long period had an increased heart rate and peripheral blood volume compared with controls. The increase in blood volume is thought to be due to excitation of heart function and not vasodilation. (ERA citation 04:052240)
