Different segments of oviduct (infundibulum, ampulla, isthmus and utero tubaljunction)of six buffaloes each during follicular and luteal phases of estrous cycle were studied. The samples were collected in 10% NBF processed for paraffin sectioning were stained with hematoxylin and eosin, Masson's trichrome, PetiodicAcid Schiff, alcian blue and PASalcian blue. The mucosa was found thrown into longitudinal folds having primary, secondary and tertiary branches. Branching was more pronounced in infundibulum and ampulla as well as during the follicular phase as compared to luteal phase. The different segments were lined with columnarto pseudostratifiedcolumnarepithelium.The cellswere ciliatedand non ciliated type. In follicular phase, the epithelium showed strong PASreaction which was con~entrated in the supranuclear zone while during the luteal phase the reaction was moderate. The reaction was granular in nature. The epithelium was also strongly positive for alcian blue and PASalcian blue during follicularphase. Thepropria submucosa, tunica muscularis and tunica serosa showed weak to mild reaction for PASand alcian blue.
