Özet

Cadmium chloride (Cd) and sodium arsenite (As) are two prominent examples of non-biodegradable substances that accumulate in ecosystems, pose a serious risk to human health and are not biodegradable. Although the toxicity caused by individual use of Cd and As is known, the toxicity of combined use (Cd+As) to mammals is poorly understood. The present study aims to investigate the hepatoprotective effect of curcumin (CUR), a naturally occurring bioactive component isolated from the root stem of Curcuma longa Linn., in preventing liver damage caused by a Cd+As mixture. A group of 30 Sprague-Dawley rats were subjected to intraperitoneal administration of Cd+As (0.44 mg/kg+5.55 mg/kg i.p.) and CUR (100 or 200 mg/kg) for a period of 14 days. The experimental results showed that the animals treated with Cd+As exhibited changes in liver biochemical parameters, inflammation and oxidative stress at the end of the experiment. Administration of CUR significantly reduced inflammation, oxidative stress and lipid peroxidation in the Cd+As plus CUR groups compared to the Cd+As group. Furthermore, histological examination of the liver tissue showed that administration of CUR had led to a significant reduction in the liver damage observed in the Cd+As group. The present study provides scientific evidence for the protective effects of CUR against lipid peroxidation, inflammation, oxidative stress and liver damage induced by Cd+As in the liver of rats. The results of our in vivo experiments were confirmed by those of our molecular modelling studies, which showed that CUR can enhance the diminished antioxidant capacity caused by Cd+As.
