FIG. 2.
(A) Change in Isc in colonic tissue in response to CCh (10−4 M). Mice were infected with five cysticercoids of H. diminuta with or without a subsequent 5-day exposure to 4% (wt/vol) DSS-containing drinking water (a negative value indicates a drop in Isc; means ± SEM; ∗ and #, P < 0.05 compared to other groups; n = 7 or 8 mice from three separate experiments). (B) Four representative Isc responses to CCh (arrow): a, control; b, H. diminuta infection; c, 4% DSS treatment; d, H. diminuta plus DSS (prophylactic protocol).
