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

Figure 1

Principal response curve (PRC) of enzyme activity in the snails under different treatments (control, mixed group, cyanobacteria group) at seven sampling events (0, 5, 10, 15, 20, 25, and 30 days after the beginning of the experiment). Bk indicates the weight of biochemical parameters measured: glutathione S-transferases (GST), acid phosphatase (ACP), and alkaline phosphatase (ALP).
