[Possibilities of the treatment of speech impairment in the acute stage of ischemic stroke using neuroprotective therapy].

Aim: To estimate an effect of cellex on the dynamics and time of speech functions recovery in the acute stage of ischemic stroke.

Material And Methods: A multicenter, randomized, double-blind, placebo controlled clinical study included 8 Russian clinical sites. Four hundred eighty patients were involved.

[Cellex in the treatment of patients with acute disturbance of cerebral blood circulation: results of a multicenter comparative open clinical trial].

Objective: To evaluate efficacy and tolerability of cellex in the treatment of patients with acute disturbance of cerebral blood circulation (ADCBC) used in the clinical practice in the Russian Federation.

Material And Methods: A trial included 178 patients with ADCBC from 6 Russian clinical centers, 146 (82%) patients were diagnosed with ischemic stroke and 32 (18%) with hemorrhagic stroke in the age of 35-80 years.

Results: One hundred and sixty-six patients have completed the trial.

Correction of vortex laser beam in a closed-loop adaptive system with bimorph mirror.

The phase correction of a vortex laser beam is undertaken in the closed-loop adaptive system including a Hartmann-Shack wavefront sensor with singular reconstruction technique and a bimorph piezoceramic mirror. After correction the vortex doughnutlike beam is focused into a beam with bright axial spot that considerably increases the Strehl ratio and optical system resolution. Since the phase break cannot be exactly reproduced on the flexible mirror surface, off-axis vortices appear in the far field at the beam periphery.

Wavefront reconstruction of an optical vortex by a Hartmann-Shack sensor.

Reconstruction the phase front of a vortex laser beam is conducted by use of a Hartmann-Shack wavefront sensor. The vortex beam in the form of the Laguerre-Gaussian LG(0)(1) mode is generated with the help of a spiral phase plate. The new reconstruction technique based on measured wavefront gradients allows one to restore the singular phase surface with good accuracy, whereas the conventional least-squares approach fails.

[Chronic posttraumatic headache in juveniles].

The paper presents a comparative analysis of biologic, social-culturological and psychological factors of the premorbid, peculiarities of personality as well as the conditions of getting a slight craniocerebral trauma (CCT) as well as the therapy in the acute period and a psychosocial situation during 1 year after the trauma in juveniles with chronic posttraumatic headache (PTH) (74 individuals) and without it (24 cases). As the main clinical variation of a chronic PTH was chronic PTH of tension, we studied comparative anamnestic data and peculiarities of personalities in 22 juveniles with a chronic headache of tension without PTH in the anamnesis. It was found common pathogenetic mechanisms of the development of both traumatic and non-traumatic cephalgias; the risk factors of PTH chronicity were identified, that was quite necessary for the elaboration of effective rehabilitation programs.
