hypersensitivity phenomenon in hydatid protoscolices irradiated by alpha particles.

Abstract

The phenomenon of hypersensitivity in hydatid protoscolices ,which isolated from infected sheep livers with hydatid cysts was studied. This protoscolices were irradiated by Polonium source (210Po) emitted alpha particles. The result showed that hypersensitivity occurs at low doses (0.04 mGy) which means the cells were high sensitive to the radiation. at (0.13 mGy) the cells show higher resistance for radiation .
