(a–d) Light micrographs: (a) the digestive gland showing a digestive tubule lined with four types of cells: digestive cell (d.c.), calcium cell (c.c.), excretory cell (ex.c.), and thin cell (t.c.). Narrow lumen (l). (b) The digestive gland of active treated snails showing presence of cellular blebs (arrows) with wildness of the lumen of the digestive tubules. (c) The digestive gland of inactive treated snails showing increases of the number of the excretory cells (ex.c.). (d) The digestive gland of inactive treated snails showing hemocytic infiltration (h) and vacuolation of the epithelial cells (v) (scale bar = 20 μm).
