OBJECTIVE: In this study, the diagnostic value of serum endothelin-1 (ET-1) levels and the therapeutic effects of bosentan have been investigated in an experimental appendicitis rat model.
MATERIALS AND METHODS: Twenty-one male Sprague-Dawley rats were chosen for the study. The rats were allocated into three groups as follows: Group 1 (control, n = 7), Group 2 (appendicitis, n = 7), and Group 3 (bosentan treatment, n = 7). At the 6th hour of the experiment, Groups 1 and 2 received 2 ml saline, and group 3 received 30 mg/kg bosentan intraperitoneally. At the 24th postoperative hour, all rats were sacrificed and evaluated histopathologically to score the severity of appendicitis. The plasma malondialdehyde, reduced and total glutathione levels, serum, and appendiceal tissue ET-1 levels were evaluated.
RESULTS: In this study, we found that the ET-1 levels were significantly increased with appendicitis (p = 0.018). The administration of bosentan can statistically significantly both decrease the histopathologic injury in the inflamed appendix and increase the serum total glutathione levels (p = 0.002).
CONCLUSIONS: The increase in plasma ET-1 levels may have a diagnostic value of acute appendicitis. We believe that manifestations that occur during the acute phase of appendicitis may be reduced with the administration of bosentan, which may also help prevent complications.
