Morphologies of protoscoleces on day 14 after irradiation with a intensity of 0 Gy (a), 10 Gy (b), 20 Gy (c), 30 Gy (d), 40 Gy (e), 50 Gy (f), and 60 Gy (g). The protoscoleces were well developed in the control group, while interruption of hooklets was noticed in the irradiation group in a dose dependent manner. The images were observed under a magnification of 100×. a: normally developed and motile protoscoleces; b: non-motile protoscoleces; c: protoscoleces subject to necrosis; d: breakdown hooks
