To potentiate the psycho- and autonomic activity of phenazepam and to decrease its side effects, cranio-cervical electrophoresis of the drug is suggested. The method is realized with the aid of a special electrode helmet which permits localizing electrodes in the frontal and occipital areas and at different levels of the lateral surfaces of the neck. Phenazepam in the amount of 1 ml of 3% solution was administered from the cathode. 194 patients with the psychovegetative syndrome in the clinical structure of neurosis or neurosis-like condition were treated. The dynamics of the psycho-vegetative status was verified with the aid of psychometric and vegetative techniques. Cerebral hemodynamics was investigated by rheoencephalography. The data obtained demonstrate that the treatment suggested improves the patients' functional status, decreases reactive anxiety, raises the tempo of sensomotor reactions and attention activity, ameliorates short-term memory, exerts a sympatholytic action, and makes cerebral hemodynamics return to normal. The method produces fewer side effects as compared to the enteral intake of phenazepam.

Experience in the use of the translabyrinthine approach in removal of neurinomas of the eighth nerve in 14 patients is analysed. It was established that the indications for translabyrinthine removal of this type of new growths should be determined from comparison of the size of the tumor and the size of the operative field with consideration for the inevitable destruction of the hearing apparatus in accomplishing the approach. The translabyrinthine approach was found to be most adequate for small tumors (measuring less than 25 mm in size). The stage-by-stage accomplishment of the translabyrinthine developed by the authors, removal of the tumor, closure of the postoperative wound, and adherence to the suggested methodical instructions ensure atraumatic performance of the operation and prevent operative and postoperative complications. In the presence of strictly determined indications, translabyrinthine removal of neurinomas of the eighth nerve is an operation causing little injury and producing favourable results.

Clinico-radiological examination of patients with a history of various types of operative treatment conducted on the craniovertebral region and cervical segment of the spine located below it established more precisely that in many cases neither decompression nor stabilization could completely arrest and eliminate the pathological process and the appearance of secondary deformities and neurological disorders in this region. That is why many operative methods for the management of lesions in this region require further study and elaboration.

Comprehensive dynamic examination of 27 patients after removal of basal meningiomas revealed some characteristic changes in the results of REG and EEG and in the neurological status. It was also found that the dynamics of the data studied differed with the course of the postoperative period. Some EEG and REG data of favourable prognostic importance were noted. The study of these data promotes objectivization of the course of the postoperative period and is thus also important in the choice of rational therapy in the postoperative period.

Seventeen of 27 patients studied before and after surgical operations for basal meningioma frequently showed forms of cardial sinusal arythmia, sinusal tachycardia and ventricular extrasystolia. These pathological changes in cardiac rhythmics appeared and were aggravated during the postoperational period. Their possible pathophysiological mechanisms, due to the effect of the tumor and operative injury to the hypothalamo-diencephalic apparatus are discussed.
