A new portable-type laser blood flowmeter was recently developed for measuring the blood flow in vessels. The sensitivity and specificity of the laser flowmeter was assessed in comparison with the well-established electromagnetic flowmeter using a canine isolated, blood-perfused ventricular tissue preparation. The laser flowmeter can record the phasic pattern of the coronary blood flow like the electromagnetic flowmeter. The extent of the changes after intracoronary administration of ACh and angiotensin II as well as coronary occlusion was almost identical between these two methods. These results suggest that the new laser flowmeter may possess potential utilities in both basic experimental and clinical practices.
