In vitro effect of antibiotics towards rabbit plasma PAF-AH enzyme activity. The amounts of each drug that induced significant increase on specific activity are expressed as μg of each bioactive compound added in the assay mixture/μL of assay volume (p < 0.05 versus control). Rabbit plasma PAF-AH specific activity is expressed as nmol of degraded PAF/min/mg of total protein in assay. Control signifies rabbit plasma PAF-AH specific activity of rabbit leukocytes in the absence of any drug. Results are the average of three independent determinations using different enzyme preparations performing duplicate samples. (* p < 0.05 compared to control).
