Haemodynamic consequences of immediate intra-anaesthesia application of intermittent positive pressure breathing in horses. Prolonged operation or a current need to improve intraoperative conditions, while anaesthesia is still on, may require applying controlled ventilation (CV). The purpose of this study was to evaluate cardiovascular effects of such a decision. Seven halothane-anaesthetized horses were the subject of our investigation, at first kept spontaneous ventilation (SV), then they were connected to respirator. After 30' CV, SV was restored and anaesthesia was continued. In those three stages of experiment haemodynamic parameters and gasometry were measured. It was found that during CV period both optimal ...
The role of sweat in maintaining the stimulation of effort homeostasis in horses. Sweat secretion was analyzed quantitatively and qualitatively in 20 horses after a 5 min. gallop at 450 m/min. The analysis revealed concentration of proteins 63.3 +/- 6.47 g/l, mainly albumins, a high level of sodium 254.43 +/- 62.84 mM/,l chloride 268.68 +/- 98.46 mM/l, potassium 98.95 +/- 49.62 mM/l and calcium 4.14 +/- 0.8 mM/l. A dependence was found between the protein concentration in serum and its quantity in sweat and between the level of potassium in sweat and its loss from the cells within a range 8.6 to 25.8 mM/l. The hypertonic horse sweat protects organism for excessive water los...
Epizootic of equine influenza in 1969 in Poland. Epidemiological observations on the course and spread of equine influenza in Poland during the 1969 epizootic were carried out. The dynamics of the spread of the disease in the country are shown graphically by voivodship. The disease incidence and mortality rates for the entire country are also shown. The highest incidence of disease and mortality rates were found to be in November 1969. A/equi-2/Warsaw/69 was identified as the causal virus. It caused the largest epizootic in the country since 1954.
The estimation of factor VIII levels in horse, cattle, sheep and pig plasma by the use of synthetic chromogenic substrate. Factor VIII level in horse, cattle, sheep and pig plasma was estimated by the use of synthetic chromogenic substrate S-2222 (benzoyl-isoleucyl-glutamyl-glycyl-arginyl-p-nitronilide). The highest level of this factor was stated in pig, the lowest one in sheep plasma.
Assay for endogenous heparin in plasma of livestock using a synthetic chromogenic substrate. The levels of endogenous heparin in the plasmas of horses, cows, sheep and pigs were determined with the use of synthetic chromogenic substrate benzoyl-isoleucyl-glutamyl-glycyl-arginyl-p-nitroanilide (S-2222). The lowest heparin concentrations were stated in cattle plasma, the highest ones in the plasma of pigs.
Haematological parameters of the Polish Primitive Horses. Average values of chosen haematological parameters have been described in a population of 90 clinically normal Polish Primitive Horses. The comparison of the results with values given in literature for horses as a whole and for other breeds enabled us to state that Polish Primitive Horses' blood is characterized by relatively low values of RBC, PCV, segmented neutrophils and monocytes, and high percentage of lymphocytes. It was demonstrated that values of some blood parameters of examined animals are similar to typical results obtained for primitive and cold-blooded horses. Moreover, it was pr...
The role of selected biochemical components of equine seminal plasma in determining suitability for deep-freezing. Experiments conducted on the freezability of 400 ejaculates collected from 64 stallions demonstrate the possibility of predicting the semen's ability to withstand the freezing/thawing process. If the sperm concentration, AspAT activity and total protein content in the seminal plasma of raw ejaculates are determined before freezing, the effects of freezing may be forecast in about 80% of the ejaculates.
