Özet

Objective: In this study, we aimed to investigate the numeric and morphological changes of goblet cells after experimental ischemia and reperfusion damage. Material and Methods: In our study, male Sprague Dawley rats were randomly divided into four groups being eight rats in each group. Groups were: control, sham, ischemia (15 minutes) and ischemia-reperfusion groups (I/R, 15 min. I/15 min.R). After the experiment, all rats were sacrificed and their jejunums were taken out. All the necessary procedures were carried out for morphological evaluation. Results: In the ischemia group, villi morphological changes from splitting up to atrophy, and were shorter; goblet cells were found to show reduction both in number and size. On the other hand, it was found that goblet cells in the crypts showed no change in number but in size. Findings in the I/R group were milder than the ischemia group, but the sizes of villi were found smaller in this group. While the number of goblet cells in the villi was normal, it was decreased in the crypts and the sizes of goblets both in the villi and in the crypts were reduced. Conclusion: We thought that during the ischemia, the number of goblets were decreased since they fall into the lumen. The rest were small because they came from the basis of the crypts; during the I/R procedure, the number of cells turned to normal because of the arrival of the goblets from the crypts to the villi. However, in this way the number in them in the crypts decreased and they looked small due to incomplete maturation.
