Abstract


Objective: The effects of montelukast against methotrexate-induced renal damage were investigated.

Materials and Methods: 35 Wistar albino female rats were divided into 5 groups as follows: Group I: Control; Group II: Montelukast (ML); Group III: Methotrexate (Mtx); Group IV: Montelukast treatment after methotrexate application (Mtx+ML); Group V: Montelukast treatment before methotrexate application (ML+Mtx). At the end of the experiment, the kidney tissues and the blood of rats were collected. Malondialdehyde (MDA) levels were determined from kidney tissues. Blood urea nitrogen (BUN) and creatinine (Cr) were assessed in the serum. In addition the kidney tissues were examined histologically.

Results: MDA, BUN and Cr levels of of group III significantly increased when compared to groups I and II. These parameters of group IV decreased when comparet to group III. The significant tubul damages were observed in only methotrexate injection group (group III) histologically. In addition, montelukast treatment (in groups IV and V) reduced these histological damages.

Conclusion: It was showed that montelukast treatment after methotrexate application could reduce methotrexate-induced experimental renal damage.

Key Words: Methotrexate; Montelukast; Kidney; Rat.
