Histological study of uterine tube in adult river buffalo during estrus cycle

For histological study of buffalo''s uterine tube، 10 genital organs of adult buffalos were sampled. General histology was taken out by H & E method، and special staining methods that used were respectively Verhoeff، toluidine blue، and PAS. This study revealed that elastic fibers exist in connective tissue of folds and wall of uterine tube and tunica muscularis، and also they exist relatively less in tunica serosa. In luteal phase، epithelium of uterine tube particularly in ampulla contains glycoprotein or carbohydrate secretion. These results revealed the importance of ampulla for primary nutrition of embryo. This study revealed that mast cells were scanty in connective tissue. Mast cell like metachromatic granules observed in cytoplasm of epithelial secretory cells of oviduct in luteal phase.
