| Abstract: The objective of the current study was to determine the immunohistochemical distribution and density of prolactin secreting cells and Anti-S100 cells of the pituitary gland in rabbit, Oryctolagus cuniculus and guinea pig, Cavia porcellus. The Immunohistochemical study indicated that prolactin-secreting cells were arranged in single, double or triple groups in the rabbit pituitary gland while they were mostly single cells in guinea pig. In both animals PRL-secreting cells were polymorphic in shape with centric or acentric nucleus. The Anti S-100 cells were scattered in pairs distalis. The S-100 positive cells sometimes had cytoplasmic processes between endocrine cells. Although PRL-secreting cells represent high percentage (44%) in the rabbit. There was no significant increase with t-value 1.11 and the probability was more than 0.05. Anti S-100 cells significally increased (54%) in guinea pig with t-value 2.46 as compared with the rabbit and the probability less than 0.05. | ||
