بررسی اثرات کورکومین بر روی نارسایی کبدی القا شده با تیواستامید در موش‌های صحرایی نر

Background and Aim: The metabolism of many drugs and toxins is done in the liver and active metabolites are created during the metabolism of these substances which many of them cause liver toxicity. Therefore, the aim of the present study was to investigate the effect of curcumin on liver toxicity induced by Thioacetamide in adult male rats. Materials and Methods: In this experimental study, 48mature female rats were divided into 6 groups including control, sham and 4 experimental groups receiving Thioacetamide (50mg/kg), Thioacetamide plus curcumin30 and 120, 60 mg/kg. In this study, Thioacetamide and curcumin were administered as intraperitoneally in 21 consecutive days. At the end, the activity of enzymes such as alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and were measured and liver structure of the animals was investigated. The results were analyzed by ANOVA and Duncan tests at a significant level of p≤0.05. Results: The results of this study showed that Thioacetamide significantly increased the activity of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase enzymes at the level of p≤0.05 compared to the control group and increased the lymphocyte invasion around the portal of the triad and tissue degradation of the liver. However, curcumin in different doses significantly reduced the activity of these enzymes and improved the liver tissue structure at the level of p≤0.05 compared to the group receiving Thioacetamide. Conclusion: The results of this study showed that Thioacetamide may increase the activity of transaminases and damage the liver tissue structure by producing oxidative stress, while the use of curcumin with thioacetamide simultaneously probably reduces the activity of transaminases and improves tissue structure due to the antioxidant properties of curcumin.
