RESUMO
The aim of this study was to determine the effect of different doses of naringenin (NAR) administration for 2 weeks in rats on brain Aquaporin-4 (AQP4), interleukin-2 (IL-2) and 8-Hydroxydeoxyguanosine (8-OhdG) levels in brain ischemia-reperfusion. Experimental groups were formed as follows; 1-Control; 2-Sham Control; 3 Ischemia/ Reperfusion (I/R); 4-Naringenin (Naringenin 50) + I/R; 5-Naringenin (naringenin 100) + I/R. I/R was performed as 1 hour occlusion of the carotid arteries (ischemia) followed by 1 hour reperfusion. Naringenin was supplied for 2 weeks by intraperitoneal. At the end of the experiment, AQP4, IL-2 and 8-OHdG levels were determined in the brain frontal cortex tissue taken from animals killed under anesthesia. AQP4, IL-2 and 8-OHdG levels increased significantly in I/R group. However, both 50 mg/kg and 100 mg/kg two-week administration of naringenin significantly decreased these increased parameters (P 0.001).The results of the study show that intraperitoneal administration of naringenin for two weeks in rats may prevent the damage caused by brain ischemia-reperfusion.
