Mitotic Activity of Gastric Mucosal Gland in the Birds

Abstract
|
|
|
Concerning the histological structure of stomach in the bird, Mollendorff´s regard to proventricle and gizzard was generally accepted. Authors were interested in their mitotic behavior, and studied with fowls and domestic duck´s gastric mucosa. Bouin fixation and Hall´s (1970) triple stain-basic fuchsin and picro-indigo carmine were performed. Mitotic index, the frequency and distribution of mitotic cells in the various glands were observed with following results:
1 The mitotic indices for the proventricle and gizzard in fowls and ducks were highest in the gland of central sinus (compound gland), moderate in the surface gland of proventricle, and lowest in the gland of gizzard.
2. Mitotic figures were most frequently seen in the isthmus of glandular epithelium in the surface gland of proventricle, in the side wall of the .gland of central sinus, and in the wall of the gizzard gland. However, mitotic figures were also scatteredly observed at the bottom and in the upper portion of the gland.
