Ca++ activity in the endolymphatic space.

O Ninoyu, A M Meyer zum Gottesberge.   

Abstract

We measured Ca++ activity in the different parts of the endolymphatic space by using a double-barrelled electrode with calcium liquid ionic exchanger. In the region of the endolymphatic sac, Ca++ activity (4.7 X 10(-4) M) was much higher than in the cochlear duct (2.7 X 10(-5) M) and semicircular canal (2.6 X 10(-4) M). These findings suggest that Ca++ may also have a significant role in abnormal states.
