Microwave Laboratory, Zhejiang Medical University, Hangzhou.

NIH pregnant mice were exposed to electromagnetic field emitted by electric blankets with 1-1.2kV/m and 0.2-0.4microT for five hours daily during their whole gestational period. Catecholamine (CA) content in the hypothalamus of their newborn offsprings was quantitatively measured with histochemical methods, and their varied behavioral activities were determined with behavioral toxicological methods. Results showed catecholamine content in exposed offsprings decreased significantly not only seven days but also 40 days after delivery as compared with the controls (P < 0.01 and P < 0.05, respectively).
