Ablation sizes and times. a Healthy liver lobes of anaesthetised rats with rich blood circulation were injected with gallium through an incision (left). The ablation size was larger 20 s after injection than 10 s after injection (right). b Photographs indicate healthy hepatic tissue after 10 s of magnetic ablation (left: wax block before H&E and TUNEL staining, right: stained tissue). The right images display the entire stained tissue (middle part) and local tissue (upper and lower parts) at the surface of the gallium (arrow) and the boundaries between ablated and normal regions (in boxes). The regions observed under high magnification are indicated by dotted blue rectangles
