摘要

The aim of present work is to evaluate the effect of static magnetic field (SMF) of intensities 10, 14, 18 and 22 mT on the dielectric properties and some liver function tests in rats. The rats were, whole body, exposed to these intensities one hour daily for one week. The dielectric constant (?), electrical conductivity (σ) and relaxation frequency (fs) were measured over frequency range 50 Hz to 2.5 MHz. Also, the rat liver function was studied through analysis of glutamate oxaloacetate transfers (GOT), glutamate pyruvate transfers (GPT) and total protein (TP) after exposure to the magnetic fields. The obtained results showed noticeable variations in normal values of ?, σ of liver tissue after the exposure to the all stated magnetic fields intensities. The levels of GOT and GPT were increased up to three times their values during the period of exposure to the magnetic fields. These variations were recovered during one week after stopping exposure but they did not return to its original control values before exposure.
