In this study, effect of mirtazapine on gastric oxidative stress and DNA injury created with methotrexate was investigated. Experimental results showed that GSH (nmol/g protein), MDA (mu mol/g protein) and MPO (mu/g protein) in the gastric tissue of the control group rats receiving methotexate are 4.97 +/- 0.37, 2.78 +/- 0.30 and 3.12 +/- 0.18, respectively. GSH, MDA and MPO measurements in the gastric tissue of rats receiving mirtazapine + methotrexate were detected to be 9.23 +/- 0.51(p < 0.0001), 1.80 +/- 0.31(p < 0.0001) and 1.63 +/- 0.25 (p < 0.0001), respectively. GSH, MDA and MPO values in the intact rat group were found 8 +/- 0.38 (p < 0,0001), 1.63 +/- 0.28 (p < 0.0001) and 1.37 +/- 0.21 (p < 0.0001), respectively. In addition, while 8-ohdG/dG quantity that DNA injury product in the control group administered methotrexate was 2.4 +/- 0.11 pmol/L, this quantity was 1.3 +/- 0.14 pmol/L (p < 0.001), 1.1 +/- 0.10 pmol/L (p < 0.001) in mirtazapine and intact group, respectively. As a result, it was seen that mirtazapine prevents increase of oxidative stress and DNA injury created with methotreaxete in the gastric tissue of rat.
