Effects of Hirudotherapy on Parameters of Plasma Hemostasis in Cows with Clinical Mastitis

Resumo

The objective of the work was to study the effects of hirudotherapy on the hemostasis plasma link in cows with clinical mastitis. The blood test for 20 lactating Ayrshire cows was performed. The most active aggregation after hirudotherapy was recorded for the collagen-induced aggregation. Platelet disaggregation capabilities decreased with the impacts of adenosine diphosphate (ADP) and ristomycin. A significant decrease in the activated partial thromboplastin time (APTT) (P ≤ 0.01), the prothrombin time (PTT) (P ≤ 0.01), and the thrombin time (TT) was revealed. The use of medical leeches in the treatment of the clinical bovine mastitis did not prove any significant effect on the adhesive-aggregation activity of platelets. However, it had a corrective effect on the plasma-coagulation link of hemostasis.
