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

Figure 3

HgCl2 induced histochemical alterations in cerebral ganglia of snail Bellamya bengalensis at different exposure periods. (a)–(d) Reduced glycogen content in cerebral ganglia; (e)–(h) AB at pH 1.0, 2.5 showed increased strong and weak acid mucins in cerebral ganglia; (a), (e) 24 hr 1000x; (b), (f) 48 hr 1000x; (c), (g) 72 hr 1000x; (d), (h) 96 hr 1000x. Bold arrow indicates decreased carbohydrate; hollow arrow indicates increased acid mucins.
