Alleviation of Tramadol-Induced Liver Toxicity in Experimental Rats by Using Kiwifruit, Turmeric Extract or Their Combination

Abstract

This work was designed to study the potential effect of kiwifruit, turmeric extract or their combination in alleviation of the liver toxicity induced by tramadol intake. Thirty rats were fed on a basal diet, six of them continued on the basal diet (negative control). The remaining rats were given tramadol daily and divided into four groups, one of them served as positive control, while the other three groups were treated daily with kiwifruit juice, turmeric water extract and their combination for four weeks. The results revealed that the positive control exhibited significant decreases in serum triglycerides, total cholesterol and HDL-c levels and a significant increase in serum LDL-c as compared to the negative control. In comparing with the positive control, the serum cholesterol, triglycerides, VLDL-c and HDL-c values increased while LDL-c value decreased significantly in the three treated groups which reached the normal values of the negative control. The findings revealed significant decreases in serum levels of ALT, AST, ALP, GGT and total bilirubin and significant increases in total protein and albumin of the treated groups in comparing with the positive control. An improvement of the antioxidant parameters was observed where the serum levels of tumor necrosis factor- α, acetylcholine esterase and total oxidative capacity decreased significantly while the levels of superoxide dismutase and total antioxidants capacity increased in all the treated groups in comparing with positive control group. It is recommended by using kiwifruit and turmeric extract in the diets of those who addicted to tramadol intake.
