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.
