The in-situ absorption of antipyrine as a measure of intestinal blood flow in Fluosol-DA haemodiluted rats.

The effect of moderate Fluosol-DA haemodilution on intestinal blood flow has been investigated in the rat. Antipyrine in-situ intestinal absorption is blood flow limited, and did not alter 0.5, 24, 48, or 72 h after haemodilution with 40 mL kg-1 Fluosol. Thus the intestinal blood flow rate is maintained as part of the physiological response to ensure adequate perfusion of the vital organ.
