Effect of pulsed magnetic fields on triglyceride and cholesterol levels in plasma of rats.
BACKGROUND
Liver is a crucial organ in metabolism. For instance liver is the main source of circulating lipoproteins.


METHODS
In this paper cholesterol and triglyceride plasma levels were measured in male rats previously exposed to pulsed magnetic fields (PMF) used in therapy. Rats underwent a one-hour exposure to a 6 mT 12 Hz PMF.


RESULTS
Twenty-four hours after the end of the exposure to the PMF the rats' livers were heavier, cholesterol and triglyceride plasma levels decreased. All these variations were significantly different according to a variance ratio test as was a rebound in triglyceride level 48 hours after the end of the exposure. Normal values were observed 48 and 96 hours after the end of exposure respectively for cholesterol and triglycerides.


CONCLUSIONS
These alterations may be due to a reversible accumulation of either triglycerides or of their precursors in liver following acute exposure to a 12 Hz PMF.
