Ulcer index (UI) and MPO levels were significantly increased
after COX-1 inhibitor pretreatment (Fig. 3A), followed by reduction
of tissue VEGF, EGF, HGF, IL-4, IL-10, and PGE2 (Fig. 3B and C). However,
COX-2 inhibitor celecoxib did not affect therapeutic activity of
ECD at any level. Ulcer index (UI) was significantly increased after
l-NAME treatment followed by reduction of mucosal NO and tissue
PGE2 levels (Fig. 3D).
