Determinação das atividades séricas de creatina quinase, lactato desidrogenase e aspartato aminotransferase em eqüinos de diferentes categorias de atividade / Determination of serum activities of creatine kinase, lactate dehydrogenase, and aspartate aminotransferase in horses of different activities classes

The creatine kinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) seric activities in horses of different activity classes (athlete, traction, and reproduction), were compared. Fifty-eight horses were alloted into three groups - group 1 with 20 athletes, "vaquejada" competitors; group 2 with 20 breeding horses; and group 3 with 18 draft horses, averaging 10 working hours daily. The average values for CK serum activity were 80.2, 83.9, and 94.4 U/l in groups 1, 2, and 3, respectively. Result of group 3 was significantly different from the other groups. The averages values for LDH were 102.5, 98.6, and 112.8 U/l in groups 1, 2, and 3, respectively, with no statistical difference between groups. The AST averages were 56.8, 33.0, and 50.1 U/l in groups 1, 2, and 3, respectively, with group 2 significantly differing from the others. Clinical biochemistry values of muscular function in horses varied according to activity category.

Avaliação do fluido peritoneal de asininos / Evaluation of peritoneal fluid from asinines

The peritoneal fluid from six female health donkeys was evaluated. In each animal, it was carried out eight abdominocentesis with 40x12 needles, at 72-hour intervals. All animals presented clinical changes, and there was higher frequency of yellow-tinged fluid with turbidity aspect. Means, and respective standard deviations, for cytology and protein concentration were: erythrocytes, 24.7±11.7x10³/mm³; leukocytes, 15.8±6.79x10³/mm³; mesothelial cells, 3.85±1.30x10³/mm³; neutrophils, 10.9±4.51x10³/mm³; lymphocytes, 1.41±0.51x10³/mm³; macrophages, 0.98±0.55x10³/mm³; eosinophils, 2.48±1.36x10³/mm³, and total proteins, 1.97±0.31 g/dl.
