Fig. 7From: An Inhibitor of Macrophage Arginine Transport and Nitric Oxide Production (CNI-1493) Prevents Acute Inflammation and Endotoxin Lethality CNI-1493 does not inhibit EDRF activitya Note that the normal response to increasing doses of the EDRF-dependent drug acetylcholine is an increasing blood pressure response (controls). In agreement with previously published work, pretreatment with L-NMA (positive controls) blunts EDRF activity. This stands in contrast to animals pretreated with CNI-1493, which manifest normal EDRF responses following acetylcholine challenge.Back to article page
