外耳道圧迫が脈搏に及ぼす影響

　緒言

　外耳道圧迫が，迷路骨壁の瘻孔を介し，或は黴毒患者に於て迷路を刺戟し所謂瘻孔症状を呈することは古くから一般に知られている。今回私達は外耳道圧迫が脈搏に及ぼす影響について観察し，一定の所見を得たので茲に報告することとした。

TAKAHASHI AND TANIGUCHI find that, wh-en pressure is applied to the external canal in a normal ear, there is a slowing in the pulse beat; in the perforated ear, a hastening. But, such a pressure applied to those who were af-fected with inner ear diese brought results th-at were equally distributed among the group, increased,decreased and no change.

The authors believe the changes that are el-icited in the normal ear are due stimulation of the parasympathetic nerves and in the perfor-ated ear to that of the sympathetic. The vari-ed results encountered in the inner ear disease may be due to various conditions under which functional balance in both ears carried out.
