Effects of PO on mice plasma aminotransferase. Plasma ALT and AST activities were measured in mice 24 h after administration of oil or CCl₄. PO-100, PO-200 and PO-400 group mice received 100 mg/kg, 200 mg/kg and 400 mg/kg PO in 0.5 ml PBS, respectively. PBS group mice received equal volume of PBS. All mice were orally administrated for seven days before CCl₄ treatment. *P < 0.05 compared with PBS group; **P < 0.05 compared with PBS group. Data are expressed as the mean ± S.E.M. (n = 5~6 animals per group).
