Abstract : 「緒言」Reilly現象は1976年にフランスで発行された医学用語事典の中で次のように定義されている. Reilly(Phenomene ou syndrome de J.). Syn. syndrome d'irritation. Ensemble de pertubrbations provoquees experimentalement, au niveau de differents organes, par une irritation du sympathique central ou peripherique (ou meme d'une muqueuse riche en fibres sensitives, telle que celle du pharynx). Cette irritation peut etre due a des agents tres divers (toxines microbiennes, agents physiques, reactions allergiques, etc.) ; elle diffuse jusqu'aux organes les plns lointains ety provoque une vaso-dilataion avec augmentaion de la permeabilite des capillaires, de l'oedeme et des infarctus, et aussi des lesions selectives du systeme reticulo-endothelial. Cet ensemble rappelle le syndrome malin observe en clinique.

Abstract : The Reilly syndrome is considered to be an experimentally or clinically induced disturbance in different organs due to the irritation of autonomic nervous system, either in the peripheral or central portions. Irritation of the somatic nerves in specific areas such as the oral cavity where the sensory fibers are abundant, induces the same type of pathological changes as the Reilly syndrome. To clarify the mechanism of Reilly syndrome in oral medicine, the effects of trigeminal stimulation on medullar DC potential changes were studied and the following results were obtained. 1. There were two types of DC potential change in the vagal nucleus area of the medulla due to trigeminal stimulation : a slight negative DC-shift during repetitive stimulation of the trigeminal nerve and a massive spreading depression-like negative DC-shift. 2. Summation of the DC-shift was observed by stimulation of the infraorbital nerve and mandibular nerve. 3. The stimulation of somatic nerves other than the trigeminal nerve such as the radial or sciatic nerve did not evoke the DC-shift of the vagal nucleus area. Neither photic nor acoustic stimulation evoked the DC-shift. 4. Continuous stimulation of tooth pulp by croton oil injection showed a progressive negative DC-shift of the vagus nucleus area. 5. The extracellular potassium concentration in the vagus nucleus area changed completely in parallel with the DC-shift. These findings suggest that the negative DC-shift evoked by trigeminal stimulation induces an elevation of excitability of vagus nucleus neurons and consequently becomes a factor in tiggering the Reilly syndrome in oral medicine.
