Photomicrographs of immunohistochemistry of cytochrome C in liver sections of the control group (a). Acrylamide-administrated groups showed decrease in the expression at 60 days (d) in contrast to the elevated expression at 30 and 45 days (b, c). Chips feeding groups at 30, 45, and 60 days (e–g) showed elevated expression. BV-treated group (h) at 60 days showed higher cytochrome C expression compared to the control. BPF-treated group (i) showing an increase of cytochrome C expression. Acrylamide-administrated group treated with either BV (j) or BPF (k) showing improving downregulated expression of cytochrome C compared to acrylamide administration at 60 days. Chips feeding group treated with either BV (l) or BPF (m) showing the normal expression that was mostly similar to the control. Immunostaining of cytochrome C scale bar 10 μm
