TNF and alkaline phosphatase measurement: As shown in Table 2, the levels of amylase, pancreatic malondialdehyde (MDA), and pathologic score in the AP group were higher than those in the normal group (P < 0.05), and the levels of pancreatic superoxide dismutase (SOD), serum TNF-α, and IL-6 in the AP model group were lower than those in the normal group (P < 0.05).
