OBJECTIVES Although numerous studies have identified damage to the cochlear and vestibular end organs as the primary site of aminoglycoside-induced ototoxicity, the effect on the saccule remains poorly understood, possibly due to lack of monitoring saccular function in experimental animals. Therefore, this study applied three kinds of aminoglycosides into(More)
The aim of this study was to establish an animal model of acoustically evoked vestibulo-collic reflex using guinea pigs. A special clamp was applied to restrain the head and body of the guinea pigs, but leaving its four legs free. Each animal underwent vestibular evoked myogenic potential (VEMP) and caloric tests using clip electrode method without general(More)
OBJECTIVES/HYPOTHESIS This study used air-conducted sound (ACS) and bone-conducted vibration (BCV) stimuli in eliciting ocular vestibular-evoked myogenic potential (oVEMP) and cervical VEMP (cVEMP) in guinea pigs. STUDY DESIGN Prospective study. METHODS Ten guinea pigs were treated with gentamicin (4 mg) on the left ear, whereas the right ear served as(More)
This study aimed to establish an animal model of ocular vestibular-evoked myogenic potential (oVEMP) in guinea pigs. Ten healthy and 10 gentamicin-treated guinea pigs underwent oVEMP test using a hand-held bone-conducted vibrator placed on the animal's forehead. All 10 healthy animals exhibited bilateral oVEMPs at the stimulus intensity of 139 dB force(More)
Recessive mutations in the SLC26A4 gene are a common cause of hereditary hearing impairment worldwide. Previous studies have demonstrated that different SLC26A4 mutations may have different pathogenetic mechanisms. In the present study, we established a knock-in mouse model (i.e., Slc26a4(tm1Dontuh/tm1Dontuh) mice) homozygous for the c.919-2A>G mutation,(More)
OBJECTIVE/HYPOTHESIS Although most studies have identified damage in the cochlea and semicircular canals as the primary sites of aminoglycoside toxicity, little attention has been devoted to the toxic effects on the otolithic organs. This study aimed to assess the toxic effect of gentamicin eardrops on the inner ear end organs via a novel inner ear(More)
Mutations in the SLC26A4 gene are a common cause of human hereditary hearing impairment worldwide. Previous studies have demonstrated that different SLC26A4 mutations have different pathogenetic mechanisms. By using a genotype-driven approach, we established a knock-in mouse model (i.e., Slc26a4(tm2Dontuh/tm2Dontuh) mice) homozygous for the common p.H723R(More)
OBJECTIVE This study investigated the influence of pathological eye movements on the recordings of ocular vestibulo-evoked myogenic potential (oVEMP). METHODS Ten patients with pathological eye movements of non-vestibular origin (nine congenital nystagmus and one opsoclonus) who had negative MRI result were assigned to Group A. Another 20 vestibular(More)
Heat shock protein 60 (HSP60) is a mitochondrial chaperone. Advanced glycation end products (AGEs) have been shown to interfere with the β-cell function. We hypothesized that AGEs induced β-cell hypertrophy and dysfunction through a HSP60 dysregulation pathway during the stage of islet/β-cell hypertrophy of type-2-diabetes. We investigated the role of HSP60(More)
INTRODUCTION Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that may be associated with systemic diseases. The association of PG with lymphoid malignancies has rarely been reported. Extranodal natural killer/T-cell lymphoma (ENKTL) is a rare but aggressive entity with a poor prognosis. Here, we report the case of a patient who had idiopathic PG(More)
