Histopathologic alteration of the retina in the A. cantonensis -infected mice after TBD treatment. (A1-A2): Normal retinas and ganglion cells of mice. (B1-B2): Retina and ganglion cells in untreated mice infected with A. cantonensis for 14 d; (C1-C2): Retina and ganglion cells in mice treated with TBD for 3 d, after having been infected with A. cantonensis for 14 d; (D1-D2): Retina and ganglion cells in untreated mice infected with A. cantonensis for 21 d; (E1-E2): Retina and ganglion cells in mice treated with TBD for 7 d having been infected with A. cantonensis for 14 d; (F1-F2): Retinas in untreated mice infected with A. cantonensis s for 28 d; (G1-G2): Retina and ganglion cells in mice treated with TBD for 7 d after having been infected with A. cantonensis for 14d (A1-G1: HE staining, bar = 100 μm; (A2-G2): electronic photo, bar = 1 μm). (H): Data are mean ± SEM of retina thickness with or without TBD treatment for 3 d, 7 d, and 14 d. *Statistically significant when compared with control (0 d infection) (P < 0.05); #Statistically significant when compared with untreated groups (P < 0.05).
