Popis: | Dehydroepiandrosterone (DHEA), a C19 steroid synthesized predominantly by the adrenal cortex, and its sulfated precursor (DHEAS) has antiglucocorticoid and immunoprotective properties. DHEA is important in modulating inflammatory responses; therefore, we hypothesized that DHEA concentrations might be altered in bovine postpartum metritis. DHEA, DHEAS, the cortisol/DHEA-ratio (C/D-ratio) and the DHEAS/DHEA ratio were determined in cows with and without clinical metritis subcategorized by the blood leukocyte numbers. Blood from the coccygeal vein of 37 pluriparous Holstein-Friesian cows was sampled 8.8 ± 0.9 days (mean ± SE) after calving. Based on clinical signs of metritis and leukocyte numbers (normal range 5–10 × 106/μl), cows were classified as healthy with leukocyte numbers in the reference range (leukocyte normal; LNH = 5954.17 ± 302.4/μl); suffering from metritis with normal leukocyte counts (LNM = 7422.22 ± 774.74/μl); or metritis with leukopenia (LLM = 3950 ± 284.31/μl P |
