Abstract

Background/aims: Folic acid modulates several disorders in humans. We investigated the effects of folic acid supplementation at varying doses on ulcer formation in the rat. Materials and Methods: Male Wistar rats were treated with 1 mg/kg, 2 mg/kg and 3 mg/kg diet of folic acid for 21 days. Gastric ulceration was induced by indomethacin, scored, and assayed to determine the concentration of mucus, malondialdehyde, catalase, and superoxide dismutase in homogenized samples. Normal saline- and ranitidine- treated groups served as negative and positive control, respectively. Results: Indomethacin caused severe damage to the glandular portion of the rats stomachs with increase in malondialdehyde concentration and reduction in mucus, catalase and superoxide dismutase concentration (p<0.001). Folic acid supplementation at 2 mg/kg diet reduced significantly the formation of gastric lesions by indomethacin, while at 3 mg/kg, potentiation of the lesions was observed (p<0.05). Malondialdehyde concentration significantly decreased and superoxide dismutase activity increased in the 2 mg/kg folic acid pre-treated group, while 3 mg/kg folic acid significantly increased the malondialdehyde concentration and decreased both catalase and superoxide dismutase. Mucus concentration was increased in the 2 mg/kg folic acid pretreated group, but decreased in the 3 mg/kg folic acid pretreated group when compared with controls. Pre-treatment with 1 mg/kg diet of folic acid produced no significant changes. Histopathological studies underlined differences in the indomethacin-induced alterations in gastric mucosal structure following pre-treatment with a 2 mg/kg or 3 mg/kg diet of folic acid. Conclusions: Folic acid is gastroprotective at the basal requirement supplemental dose; high dose may be dangerous to the integrity of the stomach.

Özet

Giriş ve Amaç: Folik asid insanlarda birçok hastalığı modüle etmektedir. Çeşitli dozlarda folik asid uygulamasının sıçanlarda ülser gelişimi üzerine olan etkisini araştırdık. Gereç ve Yöntem: Erkek Wistar sıçanlar 21 gün boyunca 1 mg/kg, 2 mg (kg ve 3 mg/kg folik asid içeren diyet ile beslendiler. İndometazin ile gastrik ülser indüklendi ve skorlandı ve ayrıca homojenize örneklerde gastrik mukus, malonildialdehid, katalaz ve süperoksid dismutaz konsantrasyonları ölçüldü. Normal salin ve ranitidin uygulanan gruplar negatif ve pozitif kontroller olarak kullanıldı. Bulgular: İndometazin sıçanların midesinin glandüler kısmında ağır hasara, malonildialdehid konsantrasyonunda artışa, mukusta, katalaz ve süperoksid dismutaz konsantrasyonlarında azalmaya neden oldu (p<0.001). Folik asit desteği (2 mg/kg) indometazine bağlı gastrik lezyonların oluşmasını azaltırken, 3 mg/kg dozda lezyon oluşumunu arttırdığı görüldü (p<0.05). Malonildialdehid konsantrasyonunda azalma ve süperoksid dismutazda artma 2 mg/kg grubunda gözlenirken, 3 mg/kg grubunda malonildialdehidde artış ve katalaz ve süperoksid dismutazda azalma gözlendi. Kontroller ile karşılaştırıldığında 2 mg/kg grubunda mukusta artış görülürken, 3 mg/kg grubunda azalma tespit edildi. Bunlara karşılık 1 mg/kg folik aist uygulaması ile anlamlı değişiklikler görülmedi. Histopatolojik incelemede 2 mg/kg veya 3 mg/kg folik asit ile birlikte indometazine bağlı gelişen değişikliklerin belirginleştiği görüldü. Sonuç: Folik asit tamamlayıcı dozda gastroprotektifken, yüksek dozlarda mide için zararlı olabilir.
