Influence of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis

Figure 1 Tissue microarrays of mesenteric lymph nodes were prepared and stained for mmunohistochemistry (× 200). (A) NF-κB expression in the treated group (6 h); (B) Bax protein expression in the sham-operated group (3 h); (C) Bax protein expression in the treated group (12 h); (D) Bcl-2 protein expression in the treated group (3 h).

Figure 2 TUNEL staining, showing the pathological changes in the mesenteric lymph nodes (× 400). (A) In the sham-operated group (6 h), there were no apoptotic cells; (B) In the model group (12 h), several apoptotic cells appeared; (C) treated group (6 h); (D) apoptotic cells were increased in the treated group (12 h).
