BLOOD-FLOW RATE IN JEJUNAL ISCHEMIA-REPERFUSION INJURY

We examined changes in the blood flow rate in the course of jejunal is chemic injury using a laser Doppler flowmeter. For this purpose, we de signed a sensor holding system, which involved the fixation of the sen sor to the jejunum and allowed their movements to be synchronized. Whe n the jejunum was reperfused after IO min of ischemia, the blood flow rate markedly increased and then gradually decreased to the initial le vel. A 30-min period of ischemia produced the slowest recovery of the blood flow rate. This system could be useful for monitoring the blood flow rate in different anatomical regions.
