We incubated E. granulosus protoscoleces in vitro with NaAsO2 at different concentrations.
NaAsO2 demonstrated dose- and time-dependent suppression against E. granulosus protoscoleces.
NaAsO2 could induce ultrastructural damages of E. granulosus protoscoleces.
Our results clearly demonstrated that NaAsO2 could enhance caspase-3 activity of E. granulosus protoscoleces.
