Patients with primary biliary cirrhosis have increased serum total antioxidant capacity measured with the crocin bleaching assay

Figure 4 CTAC values are higher in peripheral blood samples compared to hepatic vein samples. Hepatic vein samples had lower values of both TAC and CTAC compared to peripheral vein samples. This was significant only for the cirrhotic patients. In the treated PBC patients a similar trend was observed but it did not reach statistical significance. ^aP < 0.05 vs others.
