Abstract

To clarify the oxygen transport across the microvessel and oxygen distribution in the skeletal muscle, we have newly designed an intravital laser microscopy with oxygen-dependent quenching of phosphorescence technique. This microscopy was applied to microvascular and tissue pO₂ measurements in the rat cremaster muscle. From these measurements, we found a significant reduction of pO₂ levels in arterioles of different orders and large pO₂ gradients at the interface between blood and tissue, in which suggest that O₂ consumption of the smooth muscle and/or endothelium in the skeletal muscle arteriole might be high.
