Interventions/Control_1
measuring duodenal barrier function in FD patients, using mini ussing chamber system, and is compared to that in healthy volunteer.
Interventions/Control_2
mRNA is extracted from duodenal tissue, which is used for gene expression analysis in tight junctinal proteins and its regulatory factors.
Interventions/Control_3
Duodenal histological changes are evaluated with microscopical analysis. Protein expression is measured with immnohistochemical method.
