Accumulation of Eosinophils in the Infundibulum of the Bovine Oviduct Justafter Ovulation

[摘要] References(20)Cited-By(1)This study was to investigatethe localization and distribution of eosinophils (EOS) in the bovine oviduct throughoutthe estrous cycle. Histological studies revealed more abundant EOS in the infundibula ofthe oviducts ipsilateral to the preovulatory dominant follicle and the ovulated ovary. Thenumber of EOS was higher in the infundibula of the oviducts ipsilateral to the ovulatedovary than those of the oviducts contralateral to the ovulated ovary. The infundibula ofthe oviducts ipsilateral to the preovulatory dominant follicle had higher number of EOSthan those of the oviducts ipsilateral to the mid-cycle corpus luteum. The number of EOSin the isthmus, but not in the ampulla, was higher in the outer layers (tunicamuscularis and tunica serosa) than in the inner layers(tunica mucosa and tunica submucosa) during theestrous cycle. Thus, the EOS number varied with the region of the bovine oviduct, withgreater number in the infundibula of the oviduct ipsilateral to the ovulated ovary,suggesting the impact of ovulation.
