Lipid Emulsion Attenuates Acetylcholine-Induced Relaxation in Isolated Rat Aorta

Figure 3

Effect of Lipofundin MCT/LCT (0.2%) alone and combined treatment with L-arginine (10⁻⁴ M) and Lipofundin MCT/LCT (0.2%) on the acetylcholine-induced relaxation in the endothelium-intact aorta. Data () are the mean SD and are expressed as the percentage of maximal precontraction induced by 3 10⁻⁷ M phenylephrine. indicates the number of descending thoracic aortic rings. ED₅₀: versus control. Maximal relaxation: versus control; versus L-arginine (10⁻⁴ M) plus Lipofundin MCT/LCT (0.2%).
