Figure 1 Barrett’s esophagus stained by crystal violet. A: Regular observation of Barrett’s esophagus; B: Staining with crystal violet in the same region.

Figure 2 Immunostaining of p53. The upper panel shows hematoxylin and eosin staining and the lower panel shows immunostaining of p53 using the identical sample. A: (-), no p53 expression; B: (+), moderate p53 expression characterized by positive nuclear staining in 5%-10% of cells; C: (++), high p53 expression characterized by positive nuclear staining in > 10% of cells.
