The effect of thymoxamine on peripheral blood vessels as monitored by the 133Xe clearance technique

The rate of clearance of intra-articularly administred 133Xe provides an indirect method for the measurement of synovial tissue perfusion. The effect of an intra-articular injection of thymoxamine, and of isoprenaline was to increase the clearance rate whereas the converse was seen with noradrenaline. The prior administration of thymoxamine did not affect the isoprenaline response. In suitable doses, thymoxamine both prevented, and reversed the noradrenaline effect.
