Objective: To investigate the lethal effect of microwave radiation on protoscolices of hydatid\udcyst.\udMethods: The protoscolices were divided in two separate groups. The first group received\udcontinuous irradiation while the second group received repetitive irradiation. According to\udthe exposure time, the first and the second groups were divided into 8 subgroups. Non-treated\udprotoscolices were considered as the control in each experiment. The protoscolex mortality rate\udwas calculated, and changes in temperature difference in protoscolex suspension before and\udafter the irradiation and the mortality rate with the increase of exposure time were recorded.\udResults: The results showed that microwave was able to increase the mortality rate of\udprotoscolices in hydatid cyst. The mortality rate from 20% in 20 s of continuous exposure\udwas increased to 100% in 50 s. Also, the differences between the mortality rates in subgroups\udof the first and the second groups and the control were significant (P < 0.001). Although the\udeffect of temperature change in repetitive irradiation was not significant, non-thermal repetitive\udirradiation effects were obviously stronger than the thermal continuous irradiation effects.\udConclusions: It seems that, microwaves especially in the repetitive mode, may be used as a\udsupplementary measure for both treatment and prevention of hydatidosis
