Representative micrographs of liver biopsy specimens from chronic
hepatitis C patients treated without (A, B, C) or with (D, E, F) lithium
chloride. The liver biopsy specimens were subjected to hematoxylin and eosin
staining and immunoperoxidase staining for pGSK3β and Nrf2. As a
negative control, the primary antibody was replaced by preimmune IgG and no
specific staining was noted.
