[The influence of prolonged painful stimulation on adrenaline and noradrenaline concentration in different regions of the brain and in the adrenals of white rats before and after removal of the superior cervical sympathetic ganglia].

Prior to removal of the sympathetic ganglia, the sustained nociceptive stimulation decreased the adrenalin and noradrenalin content in the medulla oblongata, cerebellum, and the midbrain while increasing it in the adrenal glands. After the removal, the stimulation was followed by a shorter (except in the medulla oblongata) decrease of the adrenalin and noradrenalin content in the same brain areas; in the adrenal glands the noradrenalin contents increased.
