Abstract

Mice were radiated with 2450 MHz, 10 mW/cm2 microwave for 12 days, 1.5 h/day. After microwave radiation, compared with the normal control, the content of calcium and zinc in mice bone were significantly decreased (P < 0.05) copper, iron and manganese decreased, appulsively After Libido, a composed traditional herb medicine, and asshide asafetida were supplied seperatively, the content of calcium and trace element zinc in mice bone increased (P < 0.05). It is concluded that Libido was effective on the resistance of mice to microwave radiation. The toxicity of organotin compounds and the current pollution status.
