1 Evacuation of microscopic air bubbles from Dacron reduces complement activation and platelet aggregation  Peter G. Kalman, MD, FRCS(C), Denise A. McCullough, Charles A. Ward, PhD  Journal of Vascular Surgery  Volume 11, Issue 4, Pages (April 1990) DOI: / (90)90308-W Copyright © 1990 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

2 Fig. 1 Platelet aggregation assay. The incubated plasma samples have been added to a platelet suspension. The vertical deflection in centimeters on the recording is related to the light transmitted through the platelet suspension; the greater the aggregation, the greater the deflection. The height of deflection after 30 seconds is read in centimeters above the baseline and is noted for each sample.
