[Evaluation parameters of the glucose-infusion-test (GIT) from the biocybernetic point of view (author's transl)]

It was attempted to evaluate the usual parameters of the glucose-infusion-test (GIT) from the biocybernetic point of view by considering the blood sugar and insulin-behaviour as a dynamic characteristic according to suddenly elevated glucose level. The insulin response is characterized by biphasic behaviour and could demonstrate a combined proportional, integratuel and differential regulation type (PID-regulation). The usual parameters of the glucose-infusion-test for the blood sugar and insulin behaviour contain essential biocybernetically important informations, certain restrictions and additional suggestions are given.
