[EEG and cardiac activity indices in patients with radiation-induced sensorineural hearing loss].

EEG was made in 47 patients with neurosensory hypoacusis (NSH) of radiation origin and 20 healthy subjects unexposed to radiation. These findings were compared to those on cardiac activity. The study shows that both in the temporal and occipital leads of patients with cardiac disorders alpha-rhythm amplitude and alpha-index are significantly less than in the control group.

[Brain stem structures in the acoustic pathways in radiation exposed persons].

Short-latent acoustic evoked potentials were analysed in 163 persons exposed to radiation after the Chernobyl accident regarding their cardiovascular status. Alterations of the brain stem structures of the acoustic analyzer were most pronounced in radiation-exposed persons with cardiovascular diseases. Such alterations were also registered in 50% of radiation-exposed subjects with normal heart activity.

[The relationship between the condition of the brain stem compartments of the acoustic analyzer and rheoencephalography in people who participated in the liquidation of the consequences of the Chernobyl' nuclear plant disaster].

Pure-tone and speech threshold and suprathreshold audiometry, short-latent acoustic evoked potentials (SLAEP) and rheoencephalography (REG) were applied in examination of 67 patients with neurosensory hypoacusis (NSH) aged 21 to 45 years. These patients worked as wreckers in the zone contaminated with radionuclides 5 years and later after the Chernobyl accident. Relationships between functional condition of the truncal structures of the acoustic analyser and cerebral hemodynamics were studied.

[Preventive care and treatment of hearing problems in persons exposed to radiation].

Neurosensory hypoacusis (NSHA) was treated in 193 patients exposed to radiation consequently to the Chernobyl accident. The article describes changes observed in the examinees on audiograms, ECG, rheoencephalograms (REG) and acoustic evoked potentials. Treatment of patients with radiation-induced NSHA was aimed at normalization of tonicity of the cerebral vessels, venous outflow, pulse blood filling, arterial pressure, bioelectric activity of the brain, cardiac activity with account to hearing defects in different portions of the acoustic system.

Changes in the auditory system related to cerebral circulation in the Ukraine population after the Chernobyl disaster.

The hearing and cerebral circulation was evaluated in 100 liquidators ranging from 23 to 50 years of age 1 year and 6 to 8 years after the disaster. Also, the hearing state data was compared from 80 liquidators of the same age dwelling in clean and radionuclide-contaminated areas for 5 to 8 years. The control group consisted of 20 young healthy individuals having no history of contact with radiation.
