Figure 1

The immunohistochemical (IHC) staining and grading of Lewis x (Lex), and sialyl-Lewis x (sialyl- Lex) antigens are shown for the gastric biopsies of mice (200×). The IHC staining showed negative for two Lewis antigens and was referred to as score 0. For Lex, score 1 (A): scant staining (< 5% in parietal cells of the deep glands; score 2 (B): deep glands 5–50% staining and weak; score 3 (C): deep glands > 50% staining and strong; score 4 (D): whole layer of deep glands with superficial epithelium staining, no mucus expression; score 5 (E): whole layer with mucus expression. For sialyl- Lex, score 1 (F): only surface mucus positive; score 2 (G): Mucus and upper epithelium; score 3 (H): upper epithelium and deep glands (chief cells < 50%); score 4 (I): upper epithelium and deep glands (chief cells ≥ 50%).
