The above article published in Medicinski Glasnik online on 26 June 2014 by the Medical Association of Zenica-Doboj Canton (http://www.ljkzedo.com.ba/index.php/u-sljedecem-broju) and in Volume 11, Issue 2, pages 276-282, has been retracted by agreement between the authors, the journal Editor-in-Chief, Professor Selma Uzunović, and the Medical Association of Zenica-Doboj Canton. The reasons for this retraction are as follows: The work reported in the paper was about the role of duodenal eosinophils and mast cells in the pathogenesis of functional dyspepsia. Most of the experiments were carried out by a former member of the authors' team named Yuan Haipeng, who has left the team for more than two years. A high proportion of data in the paper had been reported in the doctoral dissertation of Yuan Haipeng in 2012, and the paper was published without the knowledge or permission of Yuan. Besides the data previously reported in the doctoral dissertation of Yuan Haipeng, the authors calculated the other data in the paper before the submission. However, it has come to the authors' attention that they had made quite a few mistakes due to a loss of the original data, which was not described in details in the dissertation.
