Abstract

Amiodarone is a currently used drug with high efficacy for the treatment acute life-threatening arrhythmias. Although the use of this drug is widespread, it is associated with unwanted systemic effects. S-methylmethionine sulphonium, which is a derivative of the methionine amino acid, defined mostly as vitamin U and various beneficial effects of Vit U have been demonstrated. The present study was planned to determine whether the vitamin U exhibits preventive effects on amiodarone-induced liver toxicity. Male Sprague-Dawley rats were randomly divided into four groups. Group I; control animals receiving corn oil. Group II; control animals receiving Vit U (50 mg/kg) for 7 days orally. Group III; animals receiving 100 mg/kg amiodarone for 7 days orally. Group IV; animals receiving Vit U orally for 7 days (in the same dose and time) 1 h prior to the administration of amiodarone. Pretreatment with vitamin U particularly decreased degenerative morphological changes such as picnotic nucleus in hepatocytes, sinusoidal dilatation, hyperemia seen in amiodarone treated individuals. On the other hand liver aspartate transaminase, alanine transaminase and alkaline phosphatase activities were increased, catalase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase activities were decreased in amiodarone group. Administration of vitamin U reversed these effects in amiodarone group. In conclusion, it might be suggested that pretreatment with vitamin U have protective effects on liver injury induced with amiodarone through decreasing oxidative stress

Özet

Amiodaron, yaşamı tehdit eden akut aritmilerin tedavisinde günümüzde kullanılmakta olan yüksek etkinliğe sahip bir ilaçtır. Bu ilaç kullanımı yaygın olmasına rağmen, istenmeyen sistemik etkiler ile ilişkilidir. Çoğunlukla U vitamini olarak tanımlanan ve metiyonin amino asidinin bir türevi olan S-metilmetiyonin sulfonyum'un çeşitli yararlı etkileri ortaya konmuştur. Bu çalışma, U vitaminin amiodaron ile indüklenen karaciğer toksisitesi üzerinde önleyici etki gösterip göstermediğini belirlemek amacı ile planlanmıştır. Erkek Sprague-Dawley sıçanlar rastgele dört gruba ayrılmıştır: 1. Grup; mısır yağı verilen kontrol hayvanlar. 2. Grup; 7 gün boyunca oral olarak U vitamini (50 mg/kg) verilen hayvanlar. 3. Grup; 7 gün boyunca oral olarak 100 mg/kg amiodaron verilen hayvanlar. 4. Grup; amiodaron uygulamasından 1 saat önce 7 gün boyunca oral olarak U vitamini (aynı doz ve zamanda) verilen hayvanlar. U vitaminin amiodaron uygulamasından önce verilmesi, amiodaron uygulanan hayvanlarda gözlenen hepatositlerdeki piknotik nukleus, sinüzoidal dilatasyon, hiperemi gibi dejeneratif morfolojik değişiklikleri kısmen azaltmıştır. Diğer taraftan, amiodaron grubunda karaciğer aspartat transaminaz, alanine transaminaz ve alkalin fosfataz aktiviteleri artmış, katalaz, süperoksit dismutaz, glutatyon peroksidaz, glutatyon-S- transferaz aktiviteleri ise azalmıştır. U vitaminin uygulanması amiodaron grubundaki bu etkileri tersine çevirmiştir. Sonuç olarak, U vitamininin önceden uygulanmasının, amiodaron ile indüklenen karaciğer hasarı üzerinde oksidatif stresi azaltarak koruyucu etkilere sahip olduğu öne sürülebilir
