The aim of the present study is to investigate the location and heterogeneity of mast cells in quail cecum. Cecum samples were fixed in basic lead acetate (BLA), Carnoy's, isotonic formaldehyde acetic acid (IFAA) and 10% neutral buffered formalin (NBF) solutions. The sections were stained with an alcian blue-critical electrolyte concentration (AB-CEC) (pH 5.8, 0.3 M MgCl2) and safranin O (SO) (pH 1.0) used in a combined method and with toluidine blue (TB) (pH 0.5). Mast-cell population was shown in highest ratios in all layers of Carnoy fixed cecum parts within TB-stained sections. Metachromatic mast cell density was determined the most in tunica mucosa layers of the middle and distal cecum. It was seen that AB-CEC (+)/SO (-) mast-cell density was greater in tunica mucosa layers of the proximal and middle cecum in IFAA and BLA fixed tissues campare to Carnoy fixation. At the end of the study; it can be said that Carnoy solution fixed the connective tissue mast cells, as well as IFAA and BLA solutions fixed the mucosal mast cells better.
