The aim of the study was to determine the hematological, biochemical and acid-base equilibrium parameters that could be referential for the population of hares inhabiting Poland. Blood for analysis was collected from 36 clinically healthy adult hares (24 females and 12 males), which were caught alive in their natural environment. The hares were observed for 48 hours to eliminate sick animals from further examinations. Before blood collection the animals were administered a mixture of ksylazyna - 2 mg/kg - and ketamina in the same dose. The following acid-base equilibrium parameters were determined from the arterial blood: pH of blood, pCO₂, HCO₃. The AST, ALT, ALP, concentration of urea, creatinine, cholesterol, triglycerides, glucose, WBC, RBC, HGB, Ht were determined from the venous blood. The concentration of calcium, phosphorus, magnesium, sodium, potassium and chlorides were determined in the blood serum. The mean of the determined parameters was: pH = 7.38, pCO₂ = 41.11 mmHg, HCO₃⁻ = 22.83 mmol/l, AST = 245 U/l, ALT = 124 U/l, ALP = 51.4 U/l, the concentration of urea = 7.2 mmol/l, creatinine = 95.7 µmol/l, cholesterol = 0.55 mmol/l, triglycerides 1.3 mmol/l, glucose = 9.24 mmol/l, WBC = 4.27 U/L, RBC = 9.74 U/L, Hb = 12.5 mmol/l, Ht = 0.58 l/l, Ca²⁺ = 2.55 mmol/l, Mg²⁺ = 1.14 mmol/l, P²⁺ = 1.37 mmol/l, Na⁺ = 146.5 mmol/l, K+ = 3.77 mmol/l, Cl⁻ = 108 mmol/l.
The aim of the study was the analysis of electrocardiographic and echocardiographic parameters in Rhodesian ridgebacks. A group of 16 Rhodesian (9 females, 7 males) in age ranges from 2 to 9 (6.2 ± 2.91) and weighing from 38kg to 56kg (44.66 ±5.78) were divided into two groups based on thyroid hormone concentration in their blood. The first group consists of 12 healthy Rhodesian ridgebacks (8 females, 4 males), and the second of 4 dogs with hypothyroidism (3 females, 1 male). Data obtained from ECG and echocardiographic examination was gathered in a computer database and submitted for analysis. The reference values were determined for ECG and echocardiographic parameters. The difference between groups was evaluated with the U Mann-Whitney test. Analyses were conducted at a significance level of p < 0.05. There was no statistically significant difference between groups. In electrocardiograms a wide range of T wave polymorphism was observed. In group I 33.3% of the dogs had a positive T wave, 33.3% biphasic, and 33.4% negative, whereas in group II 75% of Rhodesian ridgebacks were characterized by a positive T wave and 25% by biphasic. P wave duration (57.69 ± 10.85) was longer in contrast to the normal value for big species of dogs. QRS wave (67.67 ± 21.70 ms) also exceeded reference ranges. Parameters which could be markers of supraventricular or ventricular arrhythmia in Rhodesian ridgebacks have the following values: Pd – 21.25 ± 3.83 ms, QTc – 259.85 ± 17.12 ms, Tp-Te – 34.26 ± 12.62 ms. Echocardiographic measurements were quite similar to those in other breeds of dogs with a deep thorax and were within reference values determined on the basis of weight ranges.
Great, computerized sets of results of the 18 most popular biochemical examinations performed with standard, computerized methods in automated analyzers, connected for 2 (-5) years in 6 polish medical laboratories were statistical analyzed with the original JEG method. The reproducibility with the time were good. Averaged results from all laboratories were compared with reference values averaged from 4-16 bibliographic sources. Only in 4 serum constituents, all of them connected with protein metabolism, the comparative analysis (test t) shoved statistical significant differences between the laboratory results and reference values. Lover range of the Gaussian part of the distribution of laboratory results were significant diminished for the total protein (56.3 g/L ver. 64.2 g/L), and three metabolites: creatinine (41.95 umol/L ver. 64.1 umol/L), uric acid (98.4 mmol/L ver. 171.9 mmol/L), and urea (1.37 mmol/L ver. 2.6 mmol/L). In urea and total protein levels also the mean values of the Gaussian part were statistical significant diminished. These situation were confirmed with the analysis of 1068 results of albumin examination in the population of Warsaw region, which show the quantitative shifts analogue to the protein results. Confirmed were the practical usefulness of the very cheap and easy JEG method especially for the analysis of results of investigation of great populations.
