Enzyme levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) and alkaline phosphatase (ALP) increased following paracetamol induction were significantly lowered due to pretreatment with the beta-carotene (BC). This supplementation reversed the trend inducing a significant decrease in bilirubin and urea levels. Paracetamol administration significantly reduced hepatic glycogen, glutathione (GSH), glutathione-S-transferase (GST), glutathione peroxidase (GPX) and glutathione reductase (GSH-R). Pretreatment of rats with BC significantly increased the enzyme activities. The results suggest hepatoprotective activity of BC.
