Frame, Mary D. S. Conducted signals within arteriolar networks initiated by bioactive amino acids. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1012–H1021, 1999.—Our purpose was to determine the specificity of L-arginine (L-Arg)induced conducted signals for intravs. extracellular actions of L-Arg. Diameter and red blood cell velocities were measured for arterioles [18 6 1.6 (SE) μm] in the c...
