Figure 5

Neural and acid mucosubstances in cerebral ganglia of Bellamya bengalensis from ZnCl2 control group. (a) PAS: positive material in ECM of neurons, 1000x; (b)-(c) AB at pH 1.0, 2.5: stained acidic mucosubstances in ECM of neurons, 1000x. Bold arrow indicates positive staining; hollow arrow indicates increased acid mucins.
