Histological and immunological changes in uterus during the different reproductive stages at californian rabbit (Oryctolagus cuniculus) [Kaliforniya Tavşanının (Oryctolagus cuniculus) Farklı üreme Dönemlerinde Uterustaki Histolojik ve immunolojik Değişiklikler]

Rabbit is the third most commonly used animal model in different fields of scientific research,such as reproductive biology,fertility and embryo transfer studies,and immunology. this animal species,often used in antibodies production,has minority of scientific records about the immunological status of its reproductive organs. the aim of this study was to find histological and immunological changes in rabbit female reproductive tract during different reproductive stages. the study was carried out on female rabbits,divided in three groups,according to the following stages of reproductive cycle: estrous,ovulation and pregnancy. histological and immunohistochemical stains for t-and b-cells were performed on tissue samples of cornu uteri and cervix. t lymphocytes were predominant in all anatomical parts of the uterus,in all stages of the cycle. the highest number of those cells was recorded at estrous,while the lowest was recorded at pregnancy. cervix expressed more immunological activity than cornu uteri. the distribution and the number of immune positive cells in the rabbit female reproductive tract depend on its hormonal status. © 2017,veteriner fakultesi dergisi. all rights reserved.
