Abstract

Aim: Oxidative stress plays an important role in the pathogenesis of inflammatory bowel disease. We investigated antioxidant L-carnitine effect on activities of paraoxonase 1 enzyme which is also synthesized in colon and oxidative status in experimental colitis.Material and Methods: Wistar albino female rats were divided into four groups randomly: control, colitis, pre-treatment and treatment groups. To induce colitis, single dose of 1 mL acetic acid (%4) was given intrarectally to colitis, pre-treatment and treatment groups. Single dose of 500 mg/kg L-carnitine was given intraperitoneally 1 hour before inducing colitis to pre-treatment group and 24 hours after inducing colitis to treatment group. All groups were sacrificied 48 hours after intrarectally administration. Existence of colitis was confirmed by histopathological changes. Paraoxonase, arylesterase and lactonase activities, total oxidant and antioxidant status, malondialdehyde, and total sialic acid were measured in serum. Oxidative stress index was calculated from the formula.Results: While serum malondialdehyde, total sialic acid, total oxidant status and oxidative stress index were significantly elevated, serum paraoxonase, arylesterase and lactonase activities and total antioxidant status were significantly decreased in acetic-acid induced experimental colitis. In acetic-acid induced experimental colitis, L-carnitine caused a significant decrease in serum malondialdehyde, total sialic acid, total oxidant status and oxidative stress index but a significant increase in serum arylesterase and lactonase activities of treatment group only. Conclusion: L-Carnitine has an increasing effect on serum arylesterase and lactonase activities and decreasing effect on oxidative stress in acetic acid-induced experimental colitis. Therefore, L-carnitine may be useful for the treatment of inflammatory bowel disease

Özet

Amaç: Oksidatif stres inflamatuvar barsak hastalıklarının patogenezinde önemli rol oynar. Bu çalışmada, antioksidan L-karnitinin deneysel kolitte, kolonda da sentez edilen paraoksonaz 1 enzim aktivitelerine ve oksidatif duruma etkisini inceledik.Gereç ve Yöntem: Wistar albino dişi sıçanlar kontrol, kolit, ön tedavi ve tedavi olmak üzere rastgele dört gruba ayrıldı. Kolit oluşturmak için kolit, tedavi ve ön tedavi gruplarına tek doz 1 mL asetik asit (%4) intrarektal olarak uygulandı. Ön tedavi grubuna kolit oluşturulmadan 1 saat önce, tedavi grubuna ise kolit oluşturulduktan 24 saat sonra 500 mg/kg L-karnitin tek doz halinde intraperitoneal olarak verildi. Tüm gruplar intrarektal uygulamadan 48 saat sonra sakrifiye edildi. Kolit varlığı histopatolojik olarak gösterildi. Serumda paraoksonaz, arilesteraz ve laktonaz aktiviteleri, total oksidan ve antioksidan durum, malondialdehit ve total sialik asit ölçüldü. Oksidatif stres indeksi formülden hesaplandı.Bulgular: Asetik asitle kolit oluşturulan grupta serum malondialdehit, total sialik asit, total oksidan durum ve oksidatif stres indeksi anlamlı olarak artarken, paraoksonaz, arilesteraz ve laktonaz aktiviteleri ve total antioksidan durum anlamlı olarak azaldı. L-Karnitin malondialdehit, total sialik asit, total oksidan durum ve oksidatif stres indeksinde anlamlı bir azalmaya yol açarken, sadece tedavi grubunun serum arilesteraz ve laktonaz aktivitelerinde anlamlı bir artışa yol açtı.Sonuç: Asetik asitle oluşturulan deneysel kolitte L-karnitin, arilesteraz ve laktonaz aktivitelerini arttırıcı, oksidatif stresi azaltıcı bir etkiye sahiptir. Bu nedenle L-karnitin, inflamatuvar barsak hastalıklarının tedavisinde yararlı olabilir
