Abstract

BACKGROUND The present study aimed to determine the effects of alpha lipoic acid (ALA) on blood and tissue biochemical parameters, as well as tissue histopathology, in an experimental rat model of cerulein-induced acute pancreatitis (AP). METHODS Three groups consisting of eight rats each were used, as follows: Group 1, controls; Group 2, cerulein-induced pancreatitis group treated with saline; and Group 3, cerulein-induced pancreatitis group treated with ALA. AP was induced by intraperitoneal administration of cerulein (20 µg/kg) 4 times at 1-hour intervals. The animals were decapitated 12 hours after the last dose of cerulein. Blood amylase, lipase, interleukin (IL)-1ß, and tumor necrosis factor (TNF)-α levels, pancreas tissue glutathione (GSH) and malondialdehyde (MDA) levels, as well as myeloperoxidase (MPO) and Na+-K+-ATPase activity were measured. Pancreatic tissue samples were also evaluated histopathologically under a light microscope. RESULTS While plasma amylase, lipase, IL-1ß, and TNF-α levels, and tissue MDA and MPO levels significantly increased in rats with cerulean-induced AP, tissue GSH and Na+-K+-ATPase activity significantly reduced. These changes were reversed and improved with ALA treatment. CONCLUSION Our findings suggest that ALA may significantly reduce morbidity and mortality by preventing organ dysfunction induced by free radicals in the pancreas

Özet

AMAÇ Bu çalışmada, sıçanlarda seruleinle deneysel olarak oluşturulan akut pankreatit (AP) modelinde alfa lipoik asitin (ALA) kan biyokimyasal parametreleri ve doku düzeyindeki etkileri araştırıldı. GEREÇ VE YÖNTEM Her biri 8 sıçandan oluşan 3 grup oluşturuldu. Grup 1: Kontrol; Grup 2: Seruleinle pankreatit oluşturulup salin verilen grup; Grup 3: Seruleinle pankreatit oluşturulup ALA verilen grup. AP intraperitoneal olarak 20 µg/kg dozunda seruleinin 1?er saat aralıklarla 4 defa verilmesiyle oluşturuldu. Son serulein dozundan 12 saat sonra hayvanlar dekapite edildi. Kan amilaz, lipaz, interlökin (IL)-1ß, tümör nekroz faktör (TNF)-alfa düzeyleri, pankreas doku glutatyon (GSH), malondialdehid (MDA), miyeloperoksidaz (MPO) ve Na+-K+-ATPase aktivitesi belirlendi. Ayrıca pankreas doku örnekleri histopatolojik olarak mikroskopta değerlendirildi. BULGULAR Seruleinle pankreatit oluşturulan grupta kan amilaz, lipaz, IL-1ß, TNF-alfa düzeyleri, doku MDA, MPO düzeyleri anlamlı derecede artarken, doku GSH ve Na+-K+-ATPase aktivitesi anlamlı derecede azaldı. ALA tedavisiyle bu değerlerde ve histopatolojide tersine değişiklikler, düzelme ve iyileşme görüldü. SONUÇ Mevcut bulgular ALA tedavisinin, pankreasta oluşabilecek serbest radikallerin neden olduğu organ ve fonksiyon bozukluğunu önleyerek morbidite ve mortaliteyi önemli oranda azaltabileceğini düşündürmektedir.
