[The superposition of neural vasoconstrictor and local vasodilator effects on skeletal muscle vessels].
In anesthetised cats' m. gastrocnemius, under conditions of stabilised perfusion pressure, preservation of the sympathetic effect against the background of reactive and working hyperemia was shown in both rhythmic muscle contractions and in single tetani. The reactive hyperemia practically did not develop during sympathetic stimulation whereas the working one turned out to be a short-term one and considerably weakened as compared with the control.
