Abstract

Background/aims: The effects of anti-ulcerogenic drugs are dependent on the increase in prostaglandin production and reduction in leukotriene production in the gastric mucosa. Montelukast is an anti-asthmatic drug, a selective reversible cysteinyl leukotriene D4 receptor antagonist. In this study, we aimed to evaluate the anti-ulcerogenic effect of montelukast and to investigate the relati- onship between its anti-ulcerogenic effect and polymorphonuclear leukocyte infiltration in the gastric tissues. Materials and Met- hods: Male Sprague-Dawley rats were separated into five groups. Distilled water (control group), famotidine (40 mg/kg), and mon- telukast (5, 10 and 20 mg/kg) were given orally (gavage). Thirty minutes later, indomethacin (25 mg/kg) was administered to all the groups. Six hours later, the animals were sacrificed by decapitation. The ulcer indexes for each stomach and the ulcer inhibiti- on rates for each group were calculated, and the stomachs were later evaluated histopathologically (polymorphonuclear leukocyte infiltration). Results: Ulcer inhibition rates were as follows: famotidine 96.14% and montelukast 59.96%, 72.65% and 76.97% (5, 10 and 20 mg/kg, respectively). Montelukast (10 and 20 mg/kg) showed effects similar to those of famotidine histopathologically. Conclusions: In this study, it was observed that there was a relationship between the anti-ulcerogenic effect of montelukast and polymorphonuclear leukocyte infiltration in the gastric mucosa, and montelukast behaved as an anti-ulcerogenic drug both macros- copically and microscopically.

Özet

Amaç: Antiülserojenik ilaçların etkileri mide mukozasında prostoglandin üretiminin artışına ve lökotrien üretiminin azalmasına bağlıdır. Montelukast selektif reversibil sisteinil lökotrien D4 reseptör antagonisti, antiastmatik bir ilaçtır. Bu çalışmada, mon- telukastın antiülserojenik etkisi ve bu etkisinin polimorfnükleer lökosit infiltrasyonu ile ilişkisi araştırılmıştır. Gereç ve Yöntem: Erkek Sprague-Dawley sıçanlar beş gruba ayrıldı. Gruplara distile su (kontrol grubu), famotidin (40 mg/kg) ve montelukast (5- 10 ve 20 mg/kg) ağız yoluyla verildi. 30 dakika sonra bütün gruplara yine ağız yoluyla indometazin (25 mg/kg) uygulandı. 6 saat sonra, denekler sakrifiye edildi. Her mide için ülser indeksleri ve her grup için ülser inhibisyon oranları ölçüldü, daha sonra mide dokuları histopatolojik olarak (polimorfonükleer lökosit infiltrasyonu) değerlendirildi. Bulgular: Ülser inhibisyon oranları famo- tidin için 96.14%, 5-10 ve 20 mg/kg montelukast için sırasıyla 59.96%, 72.65% ve 76.97% bulundu. Montelukast (10-20 mg/kg) histopatolojik olarak famotidine benzer etkiler gösterdi. Sonuç: Bu çalışmada, montelukastın antiülserojenik etkisi ile mide mukozasındaki polimorfonükleer lökosit infiltrasyonu arasında bir ilişki olduğu gözlenmiştir ve montelukast hem makroskopik olarak hem de mikroskopik olarak antiülserojenik bir ilaç gibi davranmıştır.
