The study was carried out in 13 Polish Primitive Horses.Ten of them were subjected to stress and infected with equine influenza virus (the mixture of subtype A-equi/1 and A-equi/2). Three horses were left as controls. The coagulation time by Lee and White method and caolin-kephalin and prothrombin times in plasma citrate were determined with a coagulometer. Concentration of fibrinogen (Quick method) and platelet count (procaine method) were determined as well. The means of the above parameters before and after infection in relation to the values in control animals were compared. The results of the experiment show that the caolin-kephalin and prothrombin times have been shortened in infected horses, the platelet count has been decreased and the concentration of fibrinogen has been increased. The changes in the coagulation system were statistically significant. Thus the results of the experiment have confirmed the hypothesis that in the course of influenza infection disturbances in the coagulation system may occur.
The studies were carried out on 8 horses including two controls. Three nimals were given E. coli endotoxin twice at 24-hour intervals intravenously in a dose of 1.0 (ig/kg of body weight. The other three received the endotoxin 3 times in doses of 0.2 pg and 0.1 pg (after 3 hours) and 0.2 pg after 24 hours. In all six horses the signs of endotoxaemia of a different extent were observed. In the first group (3 horses) only insignificant statistical alterations were noticed regarding blood coagulation indices, while in the second group significant disturbances were found, i.d. a decrease in the number of thrombocytes, an increase of fibrinogen concentrations, the prolongation of the prothrombin and, in some animals, also of coalin-kep- halin times and a drop of AT III activity that indicate the occurrence of DIC syndrome.
The aim of the study was to estimate coagulation parameters during pregnancy and parturition in goats. Examinations were carried out on 20 Polish White goats, and blood was obtained five times from the jugular vein: before insemination, in the second, fourth and fifth months of pregnancy and 24 hours following parturition. TT and AT III did not change significantly during the entire experiment, however PT and APTT were significantly prolonged following parturition and increased levels of fibrinogen and D-dimer were noted
Parameters of blood clotting were elaborated by examining 84 horses of various breeds, males and females ageing from 5 months to 25 years in four seasons of a year. The animals were situated in a few breeding centers. The following parameters were examined in blood taken from the external jugular vein: coagulation time of full blood, kaolin-kephaline time, protrombine and trombine time, content of fibrinogen and in 15 Polish ponnies additionally the level of antitrombine III. The results were statistically evalueted in the t-Student test. It was found that a mean coagulation time was 12 min., kaolin-kephaline time 120 sec., protrombine time 14 sec., trombine time 27 sec., level of fibrinogen 3.7 g/l, concentration of antitrombine III 20.4 iu/ml. These values were smaller in English fullblood horses. Moreover in females the trombine time (29.5 sec.) and the content of fibrinogen (3.93 g/l) is higher than in males (25.0 sec. and 3.41 g/l, respectively). The high content of plasma antitrombine III points that a slow course of blood coagulation is a species related phenomenon.
The effect of oral magnesium chloride /Slow-Mag, 3 tablets daylyl on aggregation of platelets in a group of 29 patients with stable /average age 52.9/ and instable angina pectoris /average age 49.7/ was tested. The results show that Slow-Mag decreases the aggregation of platelets and improves effectively the metabolism of heart muscle in patients with stable and instable angina pectoris.
The purpose of this examination was to investigate the influence of intensive exertion during long distance races at distances of 60 km, 90 km, 120 km on selected indicators of blood coagulation and hematology of sport horses. The examination was performed on 40 clinically healthy pure Arabian horses, running in distance races of 60 km, 90 km, 120 km. The blood was obtained from vena jugularis externa, before and 40 min after race. The exercise activates both coagulation and fibrinolysis. The change a ratio of coagulation indicators depend on the intensity and duration of exertion: a run at a distance 60 km intensifies fibrinolysis, a run at a distance of 90 km intensifies coagulation, a run at a distance of 120 km indicates disturbances of equilibrium between coagulation and fibrinolysis. Changes in blood coagulation indicators in long distance race horses can demonstrate the pathological influence of the maladjustment of exertion to the efficiency of horses.
