  • 7-150 No detectable staining, 0; specific staining of fewer than half of the cells, 1+; specific staining of more than half of the cells, 2+; and strong continuous staining, 3+.

  • 7-151 DAF expression was shown mainly by intestinal metaplasia.

  • 7-152 Significantly increased staining compared with normal mucosa (p⩽0.003).

  • 7-153 Comparison with normal tissue not possible.
