Abstract:
The mucous glands (sublingual gland, pyloric gland, main pancreatic duct gland, duodenum gland and large intestinal gland) have been studied-by means of labelled lectins and histochemical methods. The results indicated that a large amount of mucopolysaccharide with sailic acid are found in sublingual glands and pyloric glands, while a large amount of sulfate mucopolysaccharide are observed in the other three glands. In addition, the reactivity of DBA and PNA in mucous glands are different, for example, the sublingual and large intestinal glands are negative for DBA and PNA staining. On the contrary, the pyloric glands, duodenum glands as well as main pancreatic duct glands are heavily stained with DBA, but various between the mucous glands stained with PNA. The goblet cells in duodenum, large intestine and main pancreatic duct are similar in their morphology, but the reactions of PAS, AB and lectins are different between them, even so in the same organ, the staining pattern also differ from their locations. The mucous glands and goblet cells contained different mucopolysaccharides, which might be concerr/ed with different functions in different organs.
