Özet
Acetylsalicylic acid (ASA), a cyclooxygenase inhibitor, has been used for its analgesic and antiinflammatory properties. Its stimulating effect on the immune system has recently been described. In the present study, the effect of ASA on phagocytic and microbicidal activity was investigated in vitro at the concentrations of 50, 100, 150, 250 and 500 mu g/ml in the peripheral blood polymorphonuclear leucocytes (PMNL) of twelve healthy Holstein heifers. The functions of PMNL were evaluated with flourescent microscopy using flourochrome dye, acridine orange. In this study, all the results compared to the controls at the concentrations of 50, 100 and 150 mu g/ml of ASA revealed that phagocytosis increased from 74.25 % to 80.3, 80.5 and 83.7 %, respectively. There was a statistically significant decrease of phagocytic activity of PMNL between the 500 mu g/ml of ASA and control group. In addition to this, the microbicidal activity increased at the dose of 50 mu g/ml of ASA (97.1 %). Whereas there was a decrease at doses of 250 (87.4 %) and 500 mu g/ml of ASA (87.3 %) compared with the control group (92.2 %). The results of the in vitro experiments showed that the function of bovine polymorphonuclear leucocytes was altered by different concentrations of acetylsalicylic acid.
