Preliminary angiographic study of FDP tendons of Japanese monkeys with Indian ink and latex solution showed that there were musculo-tendinous, vincular and osseo-tendinous systems of blood supply and two avascular areas in between these three systems, as in human FDP tendon. Dynamic change of microcirculation in FDP tendons of 10 Japanese monkeys was investigated by means of electrolytically generated hydrogen clearance method, which led to the following conclusions. 1. Comparison of blood flow at two avascular areas and at insertion areas of long & short vinculum of FDP tendon (VLP & VBP) with pulleys incised showed no significant difference. However, with A2 pulley being preserved, distal avascular area showed significantly less blood flow as compared to VLP insertion area. Severance of VLP & VBP resulted in hypovascularity at 4 sites, but not in avascularity. 2. Opening of A2 & A4 pulleys resulted in significant increase in blood flow at VLP & VBP insertion area, in the maximal finger extension when the two areas came underneath A2 & A4 pulleys, respectively. 3. Blood flow at VLP insertion area that came underneath A2 pulley by finger extension decreased significantly by finger flexion with 80g load, regardless of A2 pulley being preserved or severed. 4. Blood flow at the distal avascular area that came underneath A2 pulley by finger flexion showed no significant change by flexion with 80g load, but decreased by flexion with 200g load. 5. Above results led to the conclusion that the three systems of blood supply in FDP tendon are connected one another so that there exists no real avascular area. However change of finger position influences upon dynamic local microblood flow in FDP tendon, probably by making VLP tense during finger flexion and pulleys tight during forced flexion or extension.}, pages = {36--50}, title = {種々の条件下における深指屈筋腱内血流量の電解式水素クリアランス法による検討}, volume = {104}, year = {1990} }
