The aim of the research was to test the tunica mucosa of the oviduct and endometrium in female cats with ovarian cysts. Material (oviducts and uterus) was obtained during ovariohysterectomy. The investigation was carried out on oviducts and uteruses of 23 cats. The first group consisted of 15 cats which had ovarian cysts, the second group consisted of 8 cats without cysts. The organs were collected during surgery, after which they were fixed in 4% formalin for 48 h and processed routinely with paraffin embedding. Sections were cut at 6-7 µm, mounted on slides, dyed, deparaffinized in xylenes and rehydrated in graded ethanol solutions. Sections were stained with hematoxylin/eosin and van Gieson. The tunica mucosa of the oviduct in the uterus were investigated. The number of cells in the epithelium were quantified by morphometry. In endometrium, in zona glandularis atrophy of glands, as well as in the degradation of epithelial cells exsecretory ducts occur. Secretory segments are cystic dilated with remaining secretions. Hypersecretion of facial epithelium is visible. Morphological changes in ovaries and uteruses result in persistent infertility in cats.
The article describes the process of healing fractures in animals. It includes descriptions of mechanisms from the beginning of the process including inflammation, osteogenic induction and callus formation up to callus remodeling into the finished bone. It takes into the account the influence of osteosynthesis and medical modes of conduct in the healing process.
Early stages of domestic cat embryonic development are shown. The aim of this was to describe the process of fertilization, blastocyst formation, implantation and the stages of embryogenesis, which determine the initiation of gastrulation. This study, which is a histological investigation of embryogenesis processes, can be crucial for a fuller comprehension of the development of the feline embryo.
