GPT and Hyperglycemia: The main action of this potent antioxidant bile pigment to prevent IHIO-induced hyperglycemia might be primarily attributable to the difference in intrinsic glucose metabolism rather than the difference in the extent of hepatocytes injury or the amount of hepatic glucose efflux because no correlations were found between preoperative total bilirubin concentration and hepatocytes injury indices (maximum postoperative aspartate transaminase [P = 0.582] and alanine transaminase [P = 0.582], respectively).
