[Effect of bradykinin on muscular glucose uptake in man (author's transl)].
Glucose metabolism of the human forearm was studied in 4 healthy volunteers by monitoring arterial deepvenous glucose concentration differences and by the determination of muscle blood flow, using 133xenon as a tracer, during 25 min intra-brachial-arterial infusion of bradykinin (13.3 ng per min). During the infusion of the kinine the forearms glucose uptake rose continuously from 0.64 +/- 0.11 micronmoles up to 1.68 +/- 0.22 micronmoles per 100 g x min after 25 min of the infusion (p less than 0.005). The enhancement of glucose uptake was partly due to the prompt small acceleration of muscle blood flow and partly to the continuously increasing glucose extraction of the forearm. From these data it is evident that besides insulin there is another physiological agent able to enhance glucose entry into the muscle cell.
