Transitory otoacoustic emissions (TOAE) were analyzed in 48 ears of male hunters (age range: 30-45 years: mean age: 37 years) and in a population with normal hearing. All the ears had TOAE. The incidence of TOAE for the 1, 2, 3, 4, 5 and 6 KHz frequential bands was significantly lower in hunters than in the normal subjects (p < 0.001). The mean amplitude of(More)
CONCLUSION A reduction in the percentage of correct responses in the olfactory test indirectly indicated increased albuminuria and worse glomerular filtration rate (GFR) in diabetic patients. The olfactory function test is an indirect indicator of early microvascular complications in diabetic patients. OBJECTIVES Diabetes mellitus is a highly prevalent(More)
OBJECTIVE To examine electrophysiological data from auditory brainstem responses (ABRs) and distortion product otoacoustic emissions (DPOAEs) in chickens following acoustic overstimulation. MATERIAL AND METHODS A total of 15 white 15-day-old Leghorn chickens were used. The animals were anesthetized with Equithensin, and placed with their heads in a(More)
In this study we have analyzed the incidence, range, frequency spectrum and threshold of distortion products in a sample of 232 normal hearing person. 116 younger adults, 58 female ranging in age from 18 to 30 years (mean age 23.1) and 58 males ranging in age from 18 to 32 (mean age 23.7) were included in the study. In all the ears studied, the presence of(More)
OBJECTIVE To compare the toughening effects in rats induced by pure tones and a broadband noise (BBN). MATERIAL AND METHODS Sprague-Dawley female albino rats (n = 148; 8-10 weeks old) were used. Three experimental groups were established as follows. Toughening only: 38 rats, divided into 3 subgroups, were exposed to different conditioning sounds (2 and 4(More)
CONCLUSION In Scarpa neurons the cell and nuclear area increases and nuclear/cytoplasm ratio decreases with fetal age (p < 0.0001). There are statistically significant differences in cell area between all fetal groups, except for the interval 45-74 mm crown-rump-length (CRL). Displacement of a neuron within the internal auditory meatus (IAM) occurs from 9(More)
In the present study we analyze the spontaneous otacoustic emissions (SOAEs) in a sample of 232 hearing-preserved ears. The examination was performed in people of the same gender aged 18 to 32 years (mean age 23.35) and always in the ear of the same side. We have found that the incidence of the SOAEs was 42.6% of the ears and 53.5% of the individuals, being(More)
The suppressor effect of contralateral broad-band white noise stimulation at 60 dB SPL on distortion-product otoacoustic emissions (DPOAEs) from 40 human ears was examined. The sample was composed of 9 females and 11 males, age 21-28 years. All the ears had DPOAEs. The 2-6 kHz bands had an incidence of 100%, but 0.7 kHz was found in only 27%. Eighty-eight(More)
Distortion products (DP) were recorded and a morphological cochlear study was made of a sample of 60 ears from chickens (Gallus domesticus. Leghorn breed) and the ages of 15, 23, 29 and 60 days, after intoxication by intramuscular gentamicin injection (40 mg per kg weight and day for 8 days). Spontaneous or transitory otoacoustic emissions were not obtained(More)
