ABSTRACT
A new instrument, furnished with hydrogen clearance technique for measuring local blood-flow, was designed by use of new electronic components and a microcontroller. The corresponding program was developed. The curve of hydrogen clearance was sampled automatically by microcomputer, fitted into an exponential function by least square method, and then the local blood-flow was calculated. The cerebral blood-flow in the rat's striatum had been measured using the system. The fitted curve corresponds with the curve of hydrogen clearance and the obtained parameter was correct. The design of the instrument was reasonable. It can work reliably and stably. The calculated results are more accurate and they can be acquired more quickly, because the curve of hydrogen clearance is automatically sampled and analyzed by the microcomputer.
