Lipid Emulsion Attenuates Acetylcholine-Induced Relaxation in Isolated Rat Aorta

Figure 1

Effect of lipid emulsion (Lipofundin MCT/LCT ((a), ) and Intralipid ((b), )) on the acetylcholine concentration-response curves 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 rats from which descending thoracic aortic rings were derived. ED₅₀: and versus control. Maximal relaxation: versus control.
