25. The objective of a study by Abrahamsson et al. (A-22) was to investigate the anti-thrombotic effects<br />

of an inhibitor of the plasminogen activator inhibitor-1 (PAI-1) in rats given endotoxin. Experimental<br />

subjects were male Sprague–Dawley rats weighing between 300 and 400 grams. Among the data<br />

collected were the following measurements on PAI-1 activity and the lung 125 I-concentration in<br />

anesthetized rats given three drugs:<br />
