Biochemical and Ultrastructural Changes in the Hepatopancreas of Bellamya aeruginosa (Gastropoda) Fed with Toxic Cyanobacteria

Figure 6

Ultrastructural changes in the hepatopancreas of B. aeruginosa exposed to the suspension of M. aeruginosa and mixed algae, respectively. (a) The proliferation of lysosomes (yellow arrow) and heterolysosomes (green arrow) in the mixed group at 5 days postexposure, 40000x. (b) The vacuoles (green star), telolysosomes (yellow star), and heterolysosomes (green arrow) in the cyanobacterial group at 10 days postexposure, 18000x. (c) A large amount of lysosomes (yellow arrow), heterolysosomes (green arrow), and the vacuoles (green star) in the cyanobacterial group during the depuration, 8000x. (d) and (e) The telolysosome in the mixed and cyanobacterial group during the depuration, respectively, 25000x.
