Morphological study on colonic pathology in ulcerative colitis treated by moxibustion

Figure 1 The colonic mucosa shows hyperemia, edema and inflammatory cell infiltration. The goblet cells in the body of gland decrease remarkably, which are composed of columnar cells.

Figure 2 The lesion is the same as above. The arrowhead shows an infranuclear vacuole.

Figure 3 The lesion is the same as above. The arrowhead shows a crypt abscess. H.E. × 100

Figure 4 The majority of acid mucin in the body of gland disappear. AB-PAS staining × 100

Figure 5 The majority of mucin sulfate in the body of gland disappears. HID-AB staining × 100

Figure 6 The mucin in the body of gland decre ases. The amount of neutral mucin relatively increases (arrowhead). AB-PAS staining × 100

Figure 7 The colonic mucosa shows mild hyperemia, with less mucosal inflammatory cell infiltration. The goblet cells in the body of gland show no reduction. H.E. × 100

Figure 8 The reduction of acid mucin is not obvious. AB-PAS staining × 100

Figure 9 No reduction of mucin sulfate occurs. HID-AB staining × 100
