  • Look Inside

Changes of systemic autonomic nerve function after the nasal antigen provocation was studies by using plethysmograph (PTG). PTG was exa-mined at the nail of index finger. When thenasal symptoms were provoked by antigenic chal-lenge, the height of PTG waves decreased and the pulse rate increased significantly soon after occurrence of sneezing. These changes recovered gradually by 5 minutes after antigenic provocation. The similar changes of PTG and pulse rates were recognized after the nasal challenge with hista-mine and even with control disk when the nasal symptoms were provoked. These circulatory cha-nges were similar in quality but more pronounced in quantity than those recognized after the mental calculation.
