A polymethylmethacrylate total artificial heart (kinetic components made of polyetherurethane) of TNS Brno II type was implanted into seven calves (2-5 months of age) surviving for the average of 152.4 +/- 19.1 days after the implantation. During the entire post-operative period the animals received oral warfarin-sodium, acetylsalicylic acid, dipyridamole and alpha-tocopherol. Blood was taken for biochemical and hematological examinations twice a week from the jugular vein. During the experiments there were decreases in the number of red blood cells, hematocrit and hemoglobin levels. Plasma free hemoglobin and serum enzymes (alkaline phosphatase, AST, ALT, LDH) increased. Coagulation tests were abnormal because anticoagulation therapy was used. There were minimal changes in the number of white blood cells and platelets, fibrinogen, blood pH, blood glucose, serum electrolytes, bilirubin (total and direct), creatinine, blood urea, and lactate. Possible reasons for observed changes include the gradual rise in the central venous pressure and damaged function of the liver parenchyma. Other factors playing a possible role in inducing changes in laboratory findings are also discussed.

Quantifying alkaline phosphatase (ALP) isoenzymes in canine serum would provide a useful index in a clinical laboratory. To achieve this goal, we tested a semi-automatic assay combining wheat germ lectin (WGL) precipitation and chemical inhibition of isoenzymes of the TNS gene with levamisole to quantify bone ALP (BALP) and corticosteroid-induced ALP (CALP), respectively. The liver ALP (LALP) isoenzyme was then calculated from the equation: TALP = BALP + LALP + CALP BALP, LALP and CALP standards from serum of puppies, bile-duct ligated dogs and dogs on 4.4 mg/kg/day prednisolone for 30 days, respectively, were used. The suitability of standard sera was tested by affinity electrophoresis. Levamisole (4.2 mM) inhibits 98% of BALP and LALP but only 42% CALP. Multiplying measured CALP by 1.8 gives the total CALP value in serum. WGL precipitated 92.3% BALP, 23.3% LALP and 26.8% heated CALP standards. These values were used to adjust precipitated ALP to obtain the exact levels of BALP. WGL was then tested on pooled serum standards in which the relative proportions of all the ALPs were known and controlled. BALP was adequately quantified except when LALP and CALP levels were extremely high. The assay was also applicable under conditions resulting in high ALP. Therefore, combining WGL and levamisole inhibition provides an adequate separation and quantification of canine ALP isoenzymes. The method has great potential for diagnostic use and should be tested further for routine implementation.
