脳脊髄液腔加圧時の内・外リンパ圧差

抄録

The pressure difference between the perilymph and the endolymph was studied in guinea pigs, with the use of two sets of a servo-nulling system. An increase in the penlymphatic pressure induced by the infusion of artificial cerebrospinal fluid into the subarachnoid space resulted in an increase in the endolymphatic pressure, but no pressure difference between the endolymph and the perilymph was evident, regardless of the patency of the vestibular aqueduct. The authors conclude that the endolymphatic pressure is dependent on the perilymphatic pressure and there is no pressure difference between them.
