Köpeklerde Seksüel Siklus Dönemleri, Gebelik ve Pyometrada Endometrial Sitoloji Bulgular›

The purpose of this study was to investigate cellular changes of the uterus during pregnancy, pyometra and different phases of the sexual cycle in dogs using endometrial cytology. We used 30 uteruses from bitches of different ages and breeds and at heterogeneous stages of the sexual cycle (Group 1 proestrus n = 5, Group 2 estrus n = 5, Group 3 diestrus n = 5, and Group 4 anestrus n = 5) as well as animals with open cervix pyometra (Group 5 n = 5), and that were pregnant (Group 6 n = 5). The sexual cycle stage of the bitches was identified by vaginal cytology prior to ovariohysterectomy. The groups were selected from a large number of samples following vaginal cytology and ultrasonographic scanning. Blood samples (10 ml) were collected from the bitches by puncturing the v. cephalica antebrachi before surgery. The endometrium was revealed by longitudinal dissection of uterine horns after laparotomy. Uterine wall swabs were obtained from the mid part of one horn by rotating the cotton swabs on the endometrial surface. Cotton swabs were smeared over
