Figure 1.
Cadmium concentrations in the tissues of control and exposed crabs.
Data of hepatopancreas (a) and ovary (b) are expressed as mean ± standard deviation (n = 5). Statistical significance is denoted by * p < 0.05 compared to the respective control.
Figure 2.
Effects of Cd on ovarian index, hepatopancreatic index, triglyceride and lipid content.
Ovarian index (a), hepatopancreatic index (b), triglyceride levels in hemolymph (e) and lipid content expressed as percentage (weight of lipid/ tissue samples, FW: fresh weight) in the ovary (c) and hepatopancreas (d) for control and exposed crabs after 10, 15, and 20 days of experimentation. Data are expressed as mean ± standard deviation (n = 5). Comparison between the control and treatment groups is notified as * p < 0.05.
Figure 3.
Effect of Cd on lipid digestion, lipid transport and lipid synthesis of Sinopotamon henanense.
Activity of pancreatic lipase (PL, a), lipoprotein lipase (LPL, b) fatty acid synthase (FAS) in the hepatopancreas (c) and ovary (d) and acyl-CoA carboxylase (ACC) activity in the hepatopancreas (e) and ovary (f) of control and exposed crabs after 10, 15 and 20 days of experimentation. Comparison between the control and treatment groups is notified as * p < 0.05.
Figure 4.
Effect of different Cd concentrations on ATP levels and dependent enzyme activities.
Data are expressed as mean ± standard deviation (n = 5). Comparison between the control and treatment groups is notified as * p < 0.05. ATP levels: (hepatopancreas, a; ovary, b), Glucokinase (GK: hepatopancreas, c; ovary, d), NAD+-linked isocitrate dehydrogenase (IDH: hepatopancreas, e; ovary, f), and cytochrome C oxidase (COX: hepatopancreas, g; ovary, h).
Figure 5.
Effect of different Cd concentrations on NADPH levels dependent enzymes activities.
Data are expressed as mean ± standard deviation (n = 5). Statistical significance was denoted by *p < 0.05. NADPH levels: (hepatopancreas, a; ovary, b), Glucose-6-phosphate dehydrogenase (G6PDH: hepatopancreas, c; ovary, d), 6-phosphogluconate dehydrogenase (6PGDH: hepatopancreas, e; ovary, f), malic enzyme (ME: hepatopancreas, g; ovary, h), NADP+-linked isocitrate dehydrogenase (IDH: hepatopancreas, i; ovary, j).
