Abstract

This study showed that paracetamol administration to male rats at 1 g /kg of body weight for 21 days resulted in significant increase in activities of serum alanine amino transferase and aspartate amino transferase. There was an increase in the total bilirubin and creatinine levels. Paracetamol caused hepatic damage in appearance characterized with degeneration, necrosis and fatty changes in liver, as well as central vein congestion. Treatment of the damaged liver rats with 25, 50, 100, 200 mg/kg of body weight with aqueous extract of Capparis spinosa for 7, 14, 21 days led to a decrease in alanine amino transferase, aspartate amino transferase activity, total bilirubin and creatinine levels, as well as an improve in the damaged liver tissues with increasing extract concentration. The results showed that treatment of the damaged liver rats with 100, 200 mg/kg of body weight of aqueous extract of Capparis spinosa for 14, 21 days gave protection against harmful effects of paracetamol.The protective effects of this extract determined by the rebound of the enzymes and biochemical variable levels to the pretreatment levels. High doses of this extract gave a decrease in harmful effects which resulted from the paracetamol in hepatic tissues.
