ABE treatment enhances femoral head neovascularization. (A) Representative images of micro-CT reconstructed 3-D microangiography of proximal femur from control, model, ABE 10 g/kg, ABE 15 g/kg, and ABE 22.5 g/kg groups. (B) Statistical analysis was performed on differences in vessel thickness, percentage of vessel volume, vessel volume, and vessel surface in the femoral heads of rats with steroid-induced ONFH. Data are presented as the mean ± S.D. (n =10). # and ##: P <0.05 and P <0.01, respectively, in comparison with the control group. * and **: P <0.05 and P <0.01, respectively, in comparison with the model group.
