Optical microscope photographs of E. granulosus (s.s.) protoscoleces (PSC) exposed to different drugs and the non-exposed controls. A PSC after a 24-h exposure to 250 μM of tropisetron (a), granisetron (b), medium control (c), CsA (d), ABZSO (e), DMSO control (f); (magnification ×40). B PSC exposed to 250 μM of tropisetron after 24 h (a), granisetron after 175 h (b), CsA after 120 h (c), ABZSO after 140 h (d); (magnification ×400) . The presence of blebs in the tegument of the PSC (a, b, c, d), contraction of the tegument (CT) at the soma region (b, c), and calcareous corpuscles (CC) in parenchyma of the PSC (a, b, c, d) are visualized
