抄録

The tissue pO 2-dependent regulation of microvascular blood flow was evaluated in rabbit skeletal muscle in vivo. The rabbit tenuissimus muscle was prepared to observe the microcirculation. The capillary red blood cell velocity and perfused capillary density at various tissue pO 2 levels were measured from the images of microcirculation obtained by an intravital video-microscope. Both velocity and density were significantly decreased as tissue pO 2 was elevated, but the relationship between capillary flow and tissue pO 2 was not a linear correlation. In addition, the critical pO 2 value effected on microvascular blood flow regulation might exist in the tissue pO 2 ranging between 30 to 50 ninvllg. It is suggested that the arteriolar walls might detect such a pO 2 value and control capillary blood flow directly by influencing the tonus of their smooth muscle.
