Hearing thresholds were assessed using auditory brainstem response before inner ears were excised for further evaluation...

...Jing Zou; Tadao Yoshida; Usama A.

... without any brainstem or cerebellar signs. Computed tomography of his brain was normal, and the audiological results localized the lesion causing deafness to the inner ear. Surprisingly, magnetic resonance imaging showed an ischemic infarct in the right AICA territory. This case represents the fifth...

...Rika Ide; Tatsuhiko Harada; Sho Kanzaki; Hideyuki Saito; Masako Hoshikawa; Takashi Kawahara; Kaoru Ogawa Tinnitus and dizziness are symptoms of acute mountain sickness. We investigated the mechanism by which high altitude (i.e. hypobaric hypoxia) affects inner ear function by measuring transient...

...Masahiko Nishimura; Akinobu Kakigi; Taizo Takeda; Teruhiko Okada; Katsumi Doi Objective: Water homeostasis is essential for the inner ear to maintain the function of hearing and equilibrium. Bumetanide inhibits Na + -K + -2Cl – co-transporter (NKCC), which is expressed in the basolateral membrane...

...Kazunori Nishizaki; Matti Anniko The expression of each subtype (NF-L, NF-M and NF-H) of neurofilament (NF) triplet proteins in the developing rat inner ear was analysed using the immunofiuorescence method (FITC). On the 15th gestational day (GD), immunostaining of NF subtypes did not occur...

...Keijiro Fukazawa; Masafumi Sakagami; Masanori Umemoto; Takao Senda The ultrastructure and tyrosinase activity of melanocytes in the inner ear of pigmented guinea pigs were observed. Melanocytes/melanocyte-like cells were seen in the stria vascularis, the vestibular dark cell area...

...Sten Hellström; Claude Laurent; Yong-Joo Yoon The histochemical distribution of hyaluronan (hyaluronic acid, HYA) was analyzed in middle and inner ear tissues from rats by use of microwave-aided fixation, a hyaluronan-binding protein and the avidin-biotin/peroxidase staining procedure...

...M. Hultcrantz; H. Bergstedt; L. Mendel Congenital deformities of the inner ear can be associated with meningitis and varying degrees of hearing loss or deafness. Recurrent periods of meningitis, sometimes lethal, are due to communication between the middle ear cavity and the subarachnoid space...
