[Method] Alcian blue/pe- riodic acid-schiff reaction （AB/PAS） was adopted to observe and analyze the types and distribution of goblet cells in the intestinal tracts of ostrich chicks. Acid mu- copolysaccharide could be stained blue with alcian blue （AB）, and neutral mu- copolysaccharide could be stained red with periodic acid-schiff reagent （PAS）. [Result] According to AB/PAS results, goblet cells in the intestinal tracts were divided in- to four types： TypeⅠ was pure red, with AB negative result and PAS positive result containing neutral mucoitin; type Ⅱ was pure blue, with AB positive result and PAS negative result containing acidic mucoitin; type Ⅲ was purple reddish, with PAS posi- tive result greater than AB; typeⅣ was purple blue, with AB positive result greater than PAS. Large quantities of goblet cells were found in the intestinal tracts of os- trich chicks, mostly type III and IV.The quantities of goblet cells were decreased gradually in the duodenum, jejunum and ileum, while the quantities were increased in the cecum, colon and rectum. The goblet cells in the large intestine are more than that in the small intestine. The most quantities of goblet cells were contained in rectum. [Conclusion] These results indicate that the distribution of goblet cells is closely related with the structure and function of intestinal tracts. The mucus secret- ed by the goblet Cells plays a series of important roles in the digestion and mucosal immunization.展开更多
