| Research Abstract |
Cold stress(lower temperature)is cosidered to have influence on attack of any diseases in ENT field. We slected allergic rhinitis in nose diseases, Menieres disease, sudden deafness etc. in ear diseases and illness of throat uncomfortableness in throat because these diseases are affected by stress. So we perfomed experimental studies in rats and gunea pigs under cold stress.
All experiments proved to have no relatioship between theses diseases and cold stress. But we found remarkable atrophy in stria vascularlis, spirale glion cells, sensory cells on macula and ampulla, and disappearance in neuron sheath, On rats under electrical foot shock without restriction. Therefore, we have to investigate this finding in more details, for this phenomenon has not still been reported and so would like to elucidate the relation between stress and ear diseases.
