Sıçanlarda Hepatik İskemi Reperfüzyon Hasarında Farklı Dozlarda Amantadin'in Akciğer Dokusu Üzerine Etkisi

Abstract

Objective: N-Methyl D-Aspartate (NMDA) receptor blockers have been shown to have protective effects against ischemia/reperfusion (I/R) injury in various tissues. The aim of this study was to investigate the effects of 90 ve 135 mg/kg doses of amantadine on lung in hepatic I/R injury.
 Method: The rats were randomly divided into six groups: Group Sham, Group I/R, Group Amantadine-90, Group Amantadine-135, Group I/R-90 and Group I/R-135. In I/R, an atraumatic vascular clamp was applied to the structures in the left portal triad for 45 minutes and reperfusion period was 2 hours after ischemia. Malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) enzyme levels were performed the lung tissue and tissues were examined histopathologically.
 Result: A significant difference was found between the groups in terms of MDA, SOD, CAT levels (respectively; p < 0.001, p=0.008, p < 0.001). A significant difference was found between the groups in terms of lung tissue neutrophil/lymphocyte infiltration scores and alveolar wall thickening scores (respectively p=0.009, p=0.002).
 Conclusion: The biochemical and histopathological results of the present study suggested that amantadine, like other NMDA antagonist agents, may have a protective effect on lung tissues against the damage caused by hepatic I/R injury. Although we observed significant improvements after the administration of both doses studied, there was no significant difference between these two doses in terms of their success in protecting against distant organ lung injury. Amantadine appears promising as a therapeutic agent in treatment.
