Figure 1.
Swine ileum (a, b) and caecum (c, d) derived from the different experimental groups. Images show AB strong reactivity of goblet cells pertaining to ileum intestinal crypts respectively in CTR (a) and O group (b). Sial-AB treatment produced differentiated effects in goblet cell reactivity less decreased in CTR (a, inset) than in the O group (b, inset). The O group caecum intestinal glands showed AB strong positivity (c) that was reduced by sialidase digestion (d) at lower crypt level.
