| Research Abstract |
We measured the blood flow on the hind limb of rabbits using a laser doppler flow meter and/or a hydrogen clearance method. After ischemia for a duration of 8 hours, the blood flow of the hind limbs was decreased remarkably, compared with the 4 and 6 hour ischemia groups. the tissue of the skin and muscle was sharvested from experimetal limbs at preischemia, during ischemia, immediately after reperfusion, 15 and 30 minutes after reperfusion, and 1 and 2 hour after reperfusion. The EIA method was used to determine concentrations of endothelin and thromboxane A2 in the tissue. Concentrations of tissue endothelin and thromboxane A2 were directly proportional to the ischemic duration of the limb.
