Mucin Reactivity after Acute Exposure to Mercury and Zinc Chloride in Neurocytes of Freshwater Snail Bellamya bengalensis: A Histochemical Study

Figure 2

Acidic mucins in cerebral ganglia of Bellamya bengalensis from HgCl2 and ZnCl2 control group. (a)–(d) PAS: positive material in ECM of neurons. (b)–(e) AB at pH 1.0: stained acidic mucosubstances in ECM, (c)–(f) AB at pH 2.5: stained acidic mucosubstances in ECM 400x. Bold arrow indicates positive staining; hollow arrow indicates increased acid mucins.
