HISTOMORPHOLOGICAL STUDY OF ENDOCRINE CELLS IN VARIOUS REGION OF DIGESTIVE TRACT OF BUFFALO (BUBALUS BUBALIS)

The histomorphology of enteroendocrine cells were studied in different segments of gastrointestinal tract of six adult buffalo. Depending upon the histomorphological study, the enteroendocrine cells were divided into 7 different types viz. oval cell (type I), pyriform cell (type II), spherical or rounded cell (type III), elongated cell (type IV), pyramidal cell (typeV), spindle cell (type VI) and large oblong cell (type VII). Further the granulation pattern of the cell types were noted as basal granulation, dense granulation, peripheral granulation and diffuse granulation.The endocrine cells revealed differential staining character with each of the stain (Masson-Haemperl argentaffin reaction, Grimelius silver technique, Ferric ferricyanide reduction reaction, Lead haematoxylin) employed in the present study depending upon their physiological status.
