1. The effect of increase in blood glucose level on hearing loss
Abstract Objective: Previous studies have shown that hearing function is also vulnerable to the effects of diabetes mellitus which can be shown by brainstem auditory evoked potential and distortion product otoacoustic emission recordings. This study aimed to investigate the changes of brainstem auditory evoked potential and distortion product otoacoustic em

2. The effectiveness of berberine on noise-induced hearing loss: a rat model
SUMMARY OBJECTIVE: Noise-induced hearing loss is a preventable form of hearing loss that has serious social and economic impacts. This study aimed to investigate the protective effect of berberine, a potent antioxidant and anti-inflammatory agent, against Noise-induced hearing loss. METHODS: After applying distortion product otoacoustic emission, 28 female

3. The Induction of Hypothyroidism during Gestation Decreases Outer Hair Cell Motility in Rat Offspring
Abstract Introduction Perinatal hypothyroidism has a negative repercussion on the development and maturation of auditory system function. However, its long-term effect on auditory function remains unsettled. Objective To evaluate the effect of prenatal hypothyroidism on the auditory function of adult offspring in rats. Methods Pregnant Wistar rats were gi

4. The effect of very low dose pulsed magnetic waves on cochlea
Resumo Introdução: Os sistemas biológicos são geralmente expostos a forças de campo magnético em diferentes intensidades e frequências, direta ou indiretamente, na vida diária. Apesar dos resultados negativos, o uso terapêutico do campo magnético de baixa dose tem sido encontrado em estudos recentes. O efeito das forças do campo magnético sobre

5. The protective effects of whortleberry extract against cisplatin-induced ototoxicity in rats
Resumo Introdução: A cisplatina é um dos principais agentes quimioterápicos utilizados para o tratamento de muitos tipos de câncer. No entanto, a ototoxicidade, um dos efeitos colaterais mais graves da cisplatina, restringe seu uso. Objetivo: Nosso objetivo foi investigar os efeitos protetores do extrato de uva-do-monte contra a ototoxicidade induzida

6. The audiological profile of adults with and without hypertension
OBJECTIVE: To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS: This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient

7. Cochlear function in ultra-high frequencies in parents of individuals with autosomal recessive hearing loss / Função coclear em frequências ultra-altas em pais de indivíduos com deficiência auditiva autossômica recessiva
INTRODUCTION: In nonsyndromic hearing loss of recessive autosomal heritage, caused by changes in the gene GJB2 (Gap Junction Bet-2 Protein), parents of individuals with hearing loss are heterozygous carriers of a recessive allele which causes deafness, however, are asymptomatic, but may present early and mild hearing changes. OBJECTIVE: Assessing the cochlea

8. Crescimento das emissões otoacústicas evocadas - produto de distorção: estudo em neonatos / Growth of distortion product otoacoustic emission: a study neonates
Introdução: A presença das emissões otoacústicas indica a atividade de mecanismos biológicos ativos dentro da cóclea, a função de Células Ciliadas Externas. Com a medida das emissões otoacústicas - produto de distorção (EOAPD) é possível verificar o crescimento da resposta de acordo com a intensidade do estímulo sonoro apresentado (curva de

9. Ensaio clínico randomizado para avaliação do efeito otoprotetor do extrato de Ginkgo Biloba, por meio das emissões otoacústicas por produto de distorção, em pacientes sob tratamento com cisplatina
The ototoxicity is an alteration caused by drugs that compromises the auditory and vestibular functions. The cisplatin (CDDP) is a potent antineoplastic agent used for the treatment of cancer in both adults and children although it has several side effects. The cisplatin ototoxicity is a dose-limiting condition. Current opinion is that cisplatin ototoxicity

10. Distortion product otoacoustic emission in newborn exposed to ototoxic / "Emissões otoacústicas produto de distorção em recém-nascidos medicados com ototóxicos"
The amynoglicosides are frequently used in nurseries and may be toxic for the cochleo-vestibular hair cells, specially for the outer cells of the cochlear base. The distortion product otoacoustic emissions allow to evaluate specific portions of the cochlea even before the hearing sensation is altered, and are ideal for the early analysis of this auditory str

11. Caracterização morfofuncional da ototoxicidade por cisplatina em ratos: avaliação do papel da apoptose e da otoproteção por amifostina / Morfofuncional characterization of the ototoxicidade for cisplatina in rats: evaluation of the paper of apoptose and the otoproteção for amifostina
Cisplatin (cis-diamminedicloroplatinum) is an antineoplastic drug frequently used in the treatment of a variety of cancers, specially the head-and-neck cancer. Ototoxicity, however, has been noted as a common side-effect of cisplatin, which may lead to significant interruptions in treatment, possibly impacting on local tumor control and patient survival. The

12. Distortion-product otoacoustic emission input∕output characteristics in normal-hearing and hearing-impaired human ears
Distortion-product otoacoustic emission (DPOAE) input∕output (I∕O) functions were measured in 322 ears of 176 subjects at as many as 8 f2 frequencies per ear for a total of 1779 I∕O functions. The f2 frequencies ranged from 0.7 to 8 kHz in half-octave steps. Behavioral thresholds (BTs) at the f2 frequencies ranged from −5 to 60 dB hearing loss (HL).
