Prediction of traumatic pericarditis in cows using some serum biochemical and enzyme parameters.

An observational study was carried out to determine the indices in serum biochemical and enzyme parameters that would be useful in predicting the early diagnosis of traumatic reticulopericarditis (TRP) in cows. Serum glucose, protein, fibrinogen, bilirubin, BHB, Ca, IP, Mg, ALT, ALP and AST were investigated in 19 TRP cows confirmed by radiography and the results were compared to 10 healthy ones in Urmia, Iran. The mean values for glucose, Ca, Mg, IP and ALT in TRP cows were lower than in healthy cows (p<0.01), while for protein (Ptn), fibrinogen, bilirubin, BHB, ALP and AST were higher than in healthy cows (p<0.01). The correlations among parameters under study revealed that glucose, electrolytes and AST showed the greatest relationships among themselves and others. The regression results showed equations among glucose, Mg, AST (R2=0.47, SE=12.1) and Ca, IP, Mg, (R2 = 0.89, SE = 0.35). Thus, it is concluded that the serum glucose and Ca concentrations could be the main indices in early diagnosis of TRP in cows. Serum glucose (mg/dl) = 50.7 – [(8.9±3.3) Mg + (.015±0.06) AST] Serum calcium (mg/dl) = 5.38 - [(0.7±0.2) IP + (0.52±0.14) Mg].
