Abstract

Background: It is well known that stress leads to the formation of gastric mucosal lesions. Free oxygen radicals play an important role in the pathogenesis of inflammation and tissue damage. It was observed that L-tryptophan has a positive effect on gastric mucosal damage in ischemia-reperfusion injury by inhibition of free oxygen radicals. The protective effect of pentoxifylline was shown in gastric mucosal damage induced by ischemia - reperfusion or the application of some topical agents. We performed an experimental study to determine whether intragastric L-tryprophan and intramuscular pentoxifylline protect gastric mucosal damage that is induced by immobility stress. Methods: Forty rats were immobilized and divided into four groups. No treatment was made in the first group; in group 2,3 and 4, L-tryptophan, pentoxifylline and L-tryptophan + pentoxifylline were administered, respectively. The gastric lesions were assesed macroscopically and microscopically two hours following treatment. Results: In the second and fourth groups, the lesion surface area and average mucosal damage were fewer in compari-son to the control group (p<0,03). Moreover, an histopatologically improvement in the surface epithelium was observed in these groups. The average lesion score also reduced significantly (p<0,03) only in the L-tryptophan group. On the other hand, no statistically significant improvement was observed in the pentoxifylline group. Conclusion: As a result, it was concluded that L-tryptophan could play a protective role in the gastric mucosal damage associated with stress.

Özet

Amaç: Stresin gastrik m u koza l lezyon oluşumuna yol açtığı bilinmektedir. Serbest oksijen radikalleri inflaınasyon ve doku hasarının patogenezinde önemli bir rol oynarlar. L-tryptophanın serbest oksijen radikallerini inhibe ederek, iskemi-reper-füzyon zedelenmesindeki gastrik mukozal hasar üzerine olumlu bir etkiye sahip olduğu gözlenmiştir. Pentoksifilinin iske-mi-reperfüzyonla veya topikal ajanlarla oluşturulmuş gastrik mukozal hasarda koruyucu etkisi gösterilmiştir, intragastrik L-triptofan ve intramusküler pentoksifilinin hareketsizlik stresi ile indüklenmiş gastrik mukozal hasarı önleyip önleyemeyeceğini saptamak için deneysel bir çalışma düzenledik. Gereç ve yöntem: 40 rat immobilize edildikten sonra 4 gruba bölündü, ilk gruba herhangi bir tedavi verilmezken diğer gruplara sırasıyla L-triptofan, pentoksifilin ve L-triptofan + pentoksifilin uygulandı. İlaç uygulamasından 2 saat sonra midedeki lezyonlar makroskopik ve mikroskopik olarak değerlendirildi. Bulgular: L-triptofan verilen 2. ve 4. gruplarda lezyon yüzey alanı ve ortalama mukozal hasar kontrol grubuna göre daha azdı (p<0.03). Hatta bu gruplarda yüzey epitelinde histopatolojik olarak bir iyileşme gözlendi. Yalnızca L-triptofan grubunda ortalama lezyon skoru belirgin olarak azaldı (p<0.03). Öte yandan pentoksifilin grubunda istatistiksel olarak anlamlı herhangi bir iyileşme gözlenmedi. Sonuç: Sonuç olarak, L-triptofanın stresle ilişkili gastrik mukozal hasarda koruyucu bir rol oynadığı söylenebilir.
