Hepatosomatic indices of frogs in the control and exposure groups (a, n = 9). Oil red O staining of livers of frogs treated with DMSO (b), 0.06 (c), and 0.3 μg L⁻¹cis-BF (d). Magnification, × 200. e, Relative Oil Red O area in the livers (n = 3). f, The concentrations of TG and CHO in the plasma of frogs. g, Hepatosomatic indices of frogs in DCA supplemental study. h, The concentrations of TG and CHO in DCA supplemental study. Data are presented as mean ± SEM, ∗p < 0.05 and ∗∗p < 0.01 indicate significant differences compared with the control group.
