(A-F) Histological appearances of liver tissues of HG (A), PZG (B), APZG (C), TPZG (D), MPZG (E), and LPZG (F) groups (Hematoxylin-eosin staining). A: Normal histological appearance of liver tissue. B: Severe hydropic degeneration (arrowhead) and necrosis (arrow) in liver tissue. HG; healthy group, PZG; pyrazinamide group. C: Moderate hydropic degeneration (arrowhead) and necrosis (arrow) appearance in liver tissue. D: Moderate hydropic degeneration (arrowhead) and necrosis (arrow) appearance in liver tissue. E: Moderate hydropic degeneration (arrowhead) and necrosis (arrow) appearance in liver tissue. F: Mild hydropic degeneration (arrowhead) and necrosis (arrow) appearance in liver tissue. HG; healthy group, PZG; pyrazinamide group, APZG; adenosine triphosphate + pyrazinamide group, TPZG; thiamine pyrophosphate + pyrazinamide group, MPZG; melatonin + pyrazinamide group, LPZG; Liv-52 + pyrazinamide group
