A histological examination has been carried on the pars distalis of the pituitaries of twelve, healthy sexually mature balady ewes which were classified into three groups Resting, follicular and luteal phases according to the different phases of reproduction. The histological features of the TSH- ACTH-cells during resting phase has been used to establish a standard with which the subsequent changes during the follicular and luteal phases were compared. Using PAS/OG, AB/OG and PFA/AB/PAS/OG stains the TSH- and ACTH-cells were differentiated and identified from the other forms of the pars distalis cells. The topographical study of the TSH- and ACTH-cells in various regions and levels in the pars distalis of balady ewe as well as their frequencies during the different phase of reproductive cycle were discussed. Statistical analysis of the different cell count during the different phases of reproductive cycle was conducted. TSH- and ACTH-cells exhibited signs of increased cellular activities and significantly increased in number during follicular phase and in the other phases of the reproductive cycle.
对12只健康的性成熟巴拉迪母羊的垂体远侧部进行了组织学检查，这些母羊根据生殖的不同阶段分为三组：静止期、卵泡期和黄体期。静止期促甲状腺激素 - 促肾上腺皮质激素细胞的组织学特征被用作标准，用于比较卵泡期和黄体期随后发生的变化。使用过碘酸雪夫氏/橙黄G、阿尔辛蓝/橙黄G和多聚甲醛/阿尔辛蓝/过碘酸雪夫氏/橙黄G染色，从垂体远侧部的其他细胞形式中区分并鉴定出促甲状腺激素和促肾上腺皮质激素细胞。讨论了巴拉迪母羊垂体远侧部不同区域和水平的促甲状腺激素和促肾上腺皮质激素细胞的地形学研究，以及它们在生殖周期不同阶段的频率。对生殖周期不同阶段的不同细胞计数进行了统计分析。促甲状腺激素和促肾上腺皮质激素细胞在卵泡期和生殖周期的其他阶段表现出细胞活性增加的迹象，数量显著增加。
