The present study evaluates the effects of extract of Musa sapientum fruit (MSE) on ulcer index, blood glucose level and gastric mucosal cytokines, TNF-α and IL-1β and growth factor, TGF-α (affected in diabetes and chronic ulcer) in acetic acid (AA)-induced gastric ulcer (GU) in diabetic (DR) rat.
Positive H. pylori status and host TNF-alpha promoter susceptibility could not explain the pathogenesis of higher GU prevalence and pathogenesis of AIP in our population.
To clarify the role of human gastric fibroblasts in acute inflammatory conditions such as gastric ulcer, the effects of interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha on the expression of uPA and uPAR, which were suggested to be associated with tissue remodeling, in gastric fibroblasts were investigated.
Patients with gastric ulcer had a lower frequency of the TNF-308 allele 2 and a higher frequency of the LTANcoI 2.2 genotype when compared with duodenal ulcer patients (P < 0.01 and P = 0.03, respectively).
