METHODS: Mice were administered the biologically active fraction of N J, i.e., the 4th fraction (N J4), intra- peritoneally, and then injected with the stable chole- cystokinin analogue cerulein hourly for 6 h. Six hours after the last cerulein injection, the pancreas, lung, and blood were harvested for morphological examination,measurement of cytokine expression, and examination of neutrophil infiltration. RESULTS: N J4 administration attenuated the sever- ity of AP and lung injury associated with AP. It also reduced cytokine production and neutrophil infiltration and resulted in the in vivo up-regulation of heine oxy- genase-1 (HO-1). Furthermore, NJ4 and its biologically active fraction, N J4-2 inhibited the cerulein-induced death of acinar cells by inducing HO-1 in isolated pan- creatic acinar cells. CONCLUSION: These results suggest that N J4 may be a candidate fraction offering protection in AP and N J4 might ameliorate the severity of pancreatitis by induc- ing HO-1 expression.展开更多
