Results are presented as mean ± SD. Percentages of fatty acids in erythrocyte membrane phospholipids, peroxidation and unsaturation indexes, and concentrations of superoxide dismutase (SOD, μmol/mL) and glutathione peroxidase (GPx, U/L) in patients with acute pancreatitis (AP) of nonalcoholic etiology.

^aP < 0.05 comparing mild and severe AP;

^cP < 0.05,

^dP < 0.01 vs control group. PUFA: Polyunsaturated fatty acids; SFA: Saturated fatty acids.
