ABSTRACT
The authors determined criteria of medical and psychologic training of railway transport workers, with applied information digital technologies. The results obtained prove that application of software "Railway worker" ("Zheleznodorozhnik") reduces frequency and duration of "emotional stress states".

The use of transcranial Doppler sonography (TDS) in combined ultrasound diagnosis was the first to allow a noninvasive assessment of cerebral circulation. Altogether 50 patients in acute stroke period were examined. The results obtained were verified at surgery, cerebral angiography or autopsy. Changes in the velocity of the blood flow, its reversal, different Doppler sonogram pattern appeared controversial for cerebral and subarachnoid haemorrhages caused by the occlusion of the internal carotid artery or other factors of encephalomalacia. TDS employment promotes the improvement in the diagnosis of the cause underlying the acute impairment of cerebral circulation and in the prognosis of cerebral coma. The findings are correlated with routine echo-pulsography and Doppler sonography.

The authors describe the technical parameters and methodology of transcranial Doppler sonography as applied to studying the blood flow in vessels of the brain base. The results of the examination carried out in 25 healthy subjects have shown a high informative value of transcranial Doppler sonography in studying the circulation in the arterial and venous collectors. The new method is compared with the routine Doppler sonography and echopulsography.
