Slaucamo govju dzemdes morfoloģija pēcdzemdību periodā

Cow’s uterus biopsy samples were taken in winter 2004/2005 in the research and training farm “Vecauce”. Histological investigations were performed at the Institute of Anatomy and Anthropology of Riga Stradins University. Ten cows were biopsied twice – in the first and fifth week of postparturition period.
The results showed hyperemia, different level of infiltration of tissue with neutrophils, lymphocytes and macrophages, oedema, detachment of lining epithelium, and erosive surface of mucous membrane in separate samples in the first week after parturition. Four weeks after parturition, hyperplasia of basal cells, hyperemia, proliferation of endometrial glands, perivascular and periglandular infiltration with inflammatory cells, as
well as lymphatic follicules were found in separate samples. A mild positive correlation (r=0.41; p<0.01) between infiltration of endometrium with neutrophils and with macrophages was detected in the first week after parturition. A mild positive correlation (r=0.52; p<0.01) between neutrophils and lymphocytes, as well as between lymphocytes and macrophages (r=0.35; p<0.01) was found four weeks after parturition. A significant (p<0.01) increase in neutrophils, lymphocytes and macrophages was characteristic to cow’s uterus samples
between first and fifth week after parturition. These changes are suggested to correlate with immune system activation in cow’s postparturition period. Four weeks after parturition, a dense infiltration of neutrophils, lymphocytes and macrophages was observed in the uterus of dairy cows without any clinical inflammation signs in animals.
