This study was carried out to investigate light and electron
microscopic appearance, location regions, and distribution of mast cells in Angora
goats lower respiratory tract.
In this study, lower respiratory tract samples taken from 10 healthy 5-6
month-old Angora goats were used as a material.
Mast cells were .fixed in isotonic formaldehyde-acetic acid (IFAA), and were
stained metachromatically with toluidin blue and alcian blue (+) with alcian blue /
safranin O (AB/SO) combined staining. Three types of mast cell granules were
seen: homogenous electron dense, networks of cords formed by electron dense
materials in electron clear matrix and fine granular. From the trachea to the lung,
the density of mast cells was observed to increase. In spite of the fact that no
statistical significant difference was found among three regions of trachea,
significant d!fferences were seen between the average number of mast cells in per mm2
of traehea with bronchus and lung in addition to bronchus with lung (p<O.OOI).
