This study was to investigate the localization and distribution of eosinophils (EOS) in the bovine oviduct throughout the estrous cycle. Histological studies revealed more abundant EOS in the infundibula of the oviducts ipsilateral to the preovulatory dominant follicle and the ovulated ovary. The number of EOS was higher in the infundibula of the oviducts ipsilateral to the ovulated ovary than those of the oviducts contralateral to the ovulated ovary. The infundibula of the oviducts ipsilateral to the preovulatory dominant follicle had higher number of EOS than those of the oviducts ipsilateral to the mid-cycle corpus luteum. The number of EOS in the isthmus, but not in the ampulla, was higher in the outer layers (tunica muscularis and tunica serosa) than in the inner layers (tunica mucosa and tunica submucosa) during the estrous cycle. Thus, the EOS number varied with the region of the bovine oviduct, with greater number in the infundibula of the oviduct ipsilateral to the ovulated ovary, suggesting the impact of ovulation.
本研究旨在调查整个发情周期中嗜酸性粒细胞（EOS）在牛输卵管中的定位和分布。组织学研究显示，在排卵前优势卵泡同侧及排卵卵巢同侧输卵管的漏斗部，EOS数量更为丰富。排卵卵巢同侧输卵管漏斗部的EOS数量高于排卵卵巢对侧输卵管漏斗部的EOS数量。排卵前优势卵泡同侧输卵管漏斗部的EOS数量高于周期中期黄体同侧输卵管漏斗部的EOS数量。在发情周期中，峡部而非壶腹部的外层（肌层和浆膜层）的EOS数量高于内层（黏膜层和黏膜下层）。因此，牛输卵管不同区域的EOS数量有所不同，排卵卵巢同侧输卵管漏斗部的EOS数量更多，提示排卵的影响。
