Fig 1: Graph showing the differences in expression levels of mRNA encoding Tac1 (Substance P), Nk1, Nk2 and Nk3 receptors in the stomach corpus, stomach antrum (in experimental animals sections adjacent to the ulcer) and pylorus existing between control and experimental animals of the group M. Levels of Tac1, Nk1, Nk2, Nk3 mRNA were measured by Real-Time PCR. The data obtained from each sample were normalized to GAPDH. Relative quantities (RQ) of mRNA were analysed using the comparative Ct method. Each cDNA sample was amplified in doublet and all data are expressed as the mean ± SEM, *P = 0.05, **P = 0.01; (experimental vs the control animals)
