Hepatoprotective effects of baicalein against CCl4-induced acute liver injury in mice

Figure 3 Proliferation status of carbon tetrachloride induced mice after treated with or without baicalein. A, B: Immunostaining of proliferating cell nuclear antigen (PCNA) in liver sections from control (A) and baicalein (B) groups 2 d after carbon tetrachloride (CCl₄) treatment; C, D: Immunostaining of PCNA in liver sections from control (C) and baicalein (D) groups 3 d after CCl₄ treatment; E: Numbers of PCNA⁺ cells in CCl₄ induced mice after treated with or without baicalein. At least six 12-mm² tissue sections were counted for each mouse. Values represent mean ± SE (n = 6). P < 0.01 between control and baicalein groups.
