Methods Eighteen SD rats wer e ran domized into three groups: normal group (n=6), AP group (n=6) and MLHD g roup (n=6). The rat model of AP was induced by intra-peritoneal injection o f 150 g/L L-arginine with dosage of 2.0 mg/g twice within 2 hours. As control, the normal rats were injected the same amount of saline.

Results 〖WTBZ 〗Compared with AP group, the serum levels of amylase, TNF-α, IL-6, IL-10 we re signi ficantly decreased in MLHD group (P<0.05). And the SOD in pancreas increased significantly (P<0.05), but a decreasing trend of MDA level in MLHD group ( P>0.05) was observed.
