HIRUDOTHERAPY IN PRESBYACUZIS PRAECOX IN CLEAN-UP WORKERS AFTER THE CHORNOBYL ACCIDENT DURING THE POST-CATASTROPHE YEARS.

Objective: to study the hirudotherapy efficacy in presbyacuzis praecox in clean-up workers (CUWs) of the Chornobyl disaster (ChD) during the post-accident years.

Materials And Methods: From archive data of previously examined 8,136 males' CUWs we selected among them 129 persons with the determined presbyacuzis praecox during the post-accident years. According to the physical dosime- try data the individual radiation of received by CUWs during the work on a rotational scheme in the Chornobyl exclu- sion zone from the end of 1986 to 1992-1994 amounted to 0.

Vestibular and acustic dysfunctions in clean up workers of Chornobyl accident (30 years of follow up).

Objective: The objective of the work was to study the clinical and electrophysiological disorders in vestibular and acustic dysfunctions in clean up workers of Chornobyl accident depending on the dose and duration of action of ion izing radiation, the peculiarities of determined effects for 30 years after the accident.

Materials And Methods: The standard clinical and electrophysiological examinations of vestibular and acoustic ana lyzers functions were conducted in 7812 males' clean up workers including 325 persons selected for prolonged stud ies in 1986 2015. The mathematical methods of analysis were carried out using the software package SYSTAT, EPICURE and EGRET.

[State of auditory function based on data of audiometry and dynamic impedance-metry in persons exposed to radiation during liquidation of the Chernobyl AES accident].

A total of 251 men at the age of 23 to 50 have been examined with the use of audiometry and dynamic impedance metry who had obtained various doses of radiation connected with the work at the Chernobyl Power Plant. It was established that in 57.8% of the cases the audition was within the physiological norm and in 42.

[Automated analysis of vestibular nystagmus].

The method of electronystagmogram (ENG) analysis by a computer is described. ENG-signals received in the course of caloric or rotatory examinations are processed by a computer after tape recording and analog-to-digital converting. The algorithm allows main parameters of the nystagmic response to be computed in a more effective and powerful way as compared to non-computer methods.
