Amino Acids That Centrally Influence Blood Pressure and Regional Blood Flow in Conscious Rats

Figure 6

Regional blood flow measured in three arteries after intracisternal injection of L-proline, L-arginine, or D-arginine. SM, superior mesenteric artery; R, renal artery; HQ, hindquarter or the terminal aorta. Each experiment observed the flow in one of three arteries with arterial blood pressure and heart rate in the freely moving rat.
