Background: Many studies have showed that electromagnetic fields decreased WSSM. in this study the Objectives: effect of electromagnetic fields on WSSM is investigated on rats. Materials and methods: 102 male rats with weight (225-25) gr were classified in 17 groups (n=6). They were addicted by morphine injection according to Pinelli Method. 16 groups of them exposed to electromagnetic fields with 25, 50, 75 and 100 Hz frequency and with magnetic field 0/5, 1/5, 2/5 and 3/5 G intenscity. One group was chosen as control. 1) awiniWSSM in jumping, climbing, rearing, diarrhea, weight loss, ptosis by naloxan injection (5mg/kg/Ip) at all animals were investigated. Results: WSSM were obtained by counting the jumping, yawing, climbing, rearing. And the amoul of weinwt 1366 the ptosis, diarrhea were scord from +1 to +4. Conclusion: This study showed that magnetic fields caused the significant decreased on wawing, ptosis, weight loss and diarrhea at all of the exposure groups (P<0.001). Rearing and alimbing decrease significantly in groups that exposed to electromagnetic fields and this fields with 25 Hz frequency and 0/5 G intensity have minimum and with 100 and 75 Hz frequency and 3.5 G intensity have maximum effects on WSSM.
