In our previous research, we found that the level of the plasminogen activity in the plasma from Duchenne-type patients with progressive muscular dystrophy was higher than of the normal boys, though the level of the plasmin inhibitors was lower. Therefore, in the present study, we investigated the differences in the fractions of plasmin inhibitors. The subjects were nine patients (the average age being 17.1 years) who had been diagnosed, by clinical and biochemical tests, as having PMD; serving as controls were normal boys (the average age being 15 years), the patients' mothers, and the mothers of the normal boys. The plasmin inhibitors were separated from plasma using lysine-Sepharose columns according to the method of Urita et al. The determination was performed based on the method of Aoyagi et al. and an immunoreactive assay. The results were as follows: (1) No significant differences were seen between patients with PMD and control subjects with respect to either alpha 1-antichymotrypsin, antithrombin III, and alpha 1-antitrypsin or alpha 2-macroglobulin and inter-alpha-trypsin inhibitors. These results suggested that the low level of plasmin inhibitors in patients was due to the low activity of the C1 inactivator. (2) The patients with PMD showed lower values than the normal boys in the levels of C1 inactivator in plasma; similarly, the mothers of these patients showed lower values than the normal mothers.

The aim of this study was to explain the correlations between selenium deficiency, hemostatic and biochemical disorders, and the progression of pathological changes in calves diagnosed with nutritional muscular dystrophy (NMD). The study was performed on 20 calves with supplementation of 8 ml selenium and vitamin E preparation and 20 calves with symptoms of NMD. Blood was sampled from calves aged 5, 12 and 19 days. On day 19, samples of the biceps femoris muscle were collected from 6 animals in each group for histopathological analysis. The following blood parameters were determined: PLT, PT, TT, APTT, fibrinogen and D-dimer concentrations, antithrombin III activity, glucose, selenium and vitamin E concentrations, activity of CK, LDH and GSH-Px. Muscle sections were stained with H&E and HBFP. Platelet counts were significantly lower in calves with symptoms of NMD. No significant differences in coagulation parameters were observed between the groups. Sick calves were diagnosed with hyperglycemia and elevation of CK and LDH activity. Selenium and vitamin E concentrations in the blood serum were significantly lower in the experimental group together with significant drop in GSH-Px activity. Changes characteristic of Zenker's necrosis were observed in a muscle of the sick animals. To our best knowledge this is the first study in which the attempt was made to explain the relationship between selenium deficiency and changes in the coagulation system in ruminants.
