Coagulation and inflammation are closely related as part of the mechanisms of host defence during a severe infection. The aim of this study was to investigate the relation between thrombin as a factor in both the coagulative and inflammatory processes and neutrophil secretory function on the basis of lactoferrin (LF), elastase and myeloperoxidase release in the course of mastitis and metritis in cows. Thrombin generation was measured on the basis of hydrolysis of SAR-PRO-ARG-pNA and lactoferrin concentration was estimated by an ELISA method. The greatest thrombin generation was observed in the metritis group (1.18 ± 0.62 IU). The level of LF was the highest in the group of cows with mastitis (0.74 ± 0.55 mg/ml) in the first phase of the disease. In the second phase of the diseases the level of serum LF in cows with mastitis diminished to the value of 0.41 ± 0.16 mg/ml, whereas in cows with metritis the level of LF increased to 0.51 ± 0.17 mg/ml. This study reveals that the excessive production of thrombin not only causes hypercoagulatory disorders but also exaggerates neutrophil function by the release of some enzymes which may play a destructive role during disseminated intravascular coagulation (DIC). These enzymes also inhibit anticoagulative systems, thus potentially worsening the course of the disease.
