Summary: | Lungs are the target organs most affected by ischemia/reperfusion (I/R) injury, which is exacerbated when hemorrhagic shock occurs. Suppressing various proinflammatory cytokines, inflammation and oxidation that initiate and aggravate lung damage with various drugs or methods provides significant benefits in preventing lung damage.
This study aims to evaluate the protective effect of clotrimazole (CLT), an antimycotic drug, on lung injury and systemic inflammatory response in rats by creating an experimental model of a ruptured abdominal aortic aneurysm (RAAA).
Thirty-six male Sprague Dawley rats were randomly divided into 5 groups: sham, sham+CLT, sham+polyethylene glycol (PEG), shock+ischemia/reperfusion (SIR), and SIR+CLT. Saline, CLT and PEG were administered in the sham groups without shock and I/R. The hemorrhagic shock was developed in SIR groups by drawing blood for 1 h to keep the mean arterial pressure at 50 mm Hg. After 60 min, the SIR+CLT group was given 20 mg/kg CLT; then, the aortic clamps were opened, and rats were left for 120 min of reperfusion. The blood taken to create hemorrhagic shock was returned in a controlled manner during this time. At the end of the reperfusion procedure, samples were taken for cytokine levels in serum and lung tissue and for other biochemical analyses. Blood gas, histopathological examination and wet/dry weight measurements were performed to assess lung injury.
An increase was observed in all parameters in the SIR group compared to the sham group. In the SIR+CLT group, the serum myeloperoxidase (MPO), tumor necrosis factor alpha (TNF-α), lung MPO values, histologically lung injury scores, and lung tissue wet/dry ratio were decreased significantly when compared to the SIR group (p < 0.05).
These results indicate that CLT may reduce the systemic inflammatory response and lung injury due to shock and I/R in an experimental model of RAAA. |
