[The impact of therapy with Mexidol on neurological deficit and functional outcome in patients with ischemic stroke: a systematic review and meta-analysis]. / Vliyanie terapii preparatom Meksidol na regress nevrologicheskogo defitsita i funktsional'nyi iskhod u patsientov s ishemicheskim insul'tom: sistematizirovannyi obzor i metaanaliz.

OBJECTIVE: To evaluate systematically the published peer-reviewed literature and estimate the effect of therapy with Mexidol on the course and outcomes of ischemic stroke (II) in adult patients. MATERIAL AND METHODS: The meta-analysis included 11 studies reported In Russian (2 randomized controlled studies, 9 non-randomized, unblinded cohort studies). RESULTS: The results obtained indicate a positive effect of Mexidol on the course of II in the treated adult patients: we found statistically significant decrease in NIHSS scores on days 7-10 and 21-24 and in modified Rankin scale scores on days 5-7 and days 10-14 compared with the control group. The cumulative effect of the drug was shown: the between-group difference of the NIHSS scores increases with the course of observation time. The effect of Mexidol on indicators on the NIHSS scale is more significant, the greater the initial severity of the patient's neurological deficit. CONCLUSION: Heterogeneity in study designs and patient characteristics has resulted in significant statistical heterogeneity, and the evidence presented at the time of writing requires further examination as new data become available.

[Biomarkers of brain damage and inflammation in patients with acute cerebral ischemia]. / Biomarkery povrezhdeniya mozga i vospaleniya u patsientov s ostroi tserebral'noi ishemiei.

OBJECTIVE: To study the pathogenetic and clinical significance of factors of hypoxic brain damage and inflammatory mediators in the development of stroke, to improve the diagnosis using laboratory markers of brain damage and inflammation in patients with acute cerebrovascular accident. MATERIAL AND METHODS: We examined 55 people with stroke of the ischemic type at the age of 74 (67; 80) years, the comparison group consisted of 25 volunteers at the age of 65.0 (62.0; 66.5) years. Depending on the outcome of ischemic stroke, patients were assigned to the discharged group or to the deceased group. Blood serum and cerebrospinal fluid (CSF) S100b protein, glial fibrillar acidic protein and interleukin-6 (IL-6); blood serum neurospecific enolase, and cortisol and C-reactive protein (CRP) were determined. Clinical blood test and assessment of fibrinogen content were performed on days 1, 3 and 10 of stroke. RESULTS: There is an increase in the levels of markers of brain tissue damage and systemic inflammation in the blood and CSF in response to cerebral ischemia that reflects the synergy of these pathological processes in patients with stroke, their association with the severity of stroke and its outcome. CONCLUSION: The results indicate that the postischemic release of neurospecific proteins, an increase in the content of IL-6, CRP, and cortisol make it possible to additionally characterize the severity of stroke and the body's response to damage, and predict the outcome of the disease.

[Neuromidin in the treatment of cognitive impairment in the early rehabilitation period of ischemic stroke].

Clinical, neuropsychological and neurophysiological examination was performed in 53 patients, aged 33-75 years, in the early rehabilitation period of the first hemispheric ischemic stroke. Cognitive functions were measured with the MMSE, the FAB, the Clock Drawing Test, the 5-Word test, the Schulte probe, verbal fluency test, etc. Cognitive evoked potentials were recorded in 30 patients. Examination was carried out a month after the stroke and after 2 months of therapy with neuromidin (ipidacrinum). The control group consisted of 37 people without stroke in the case history. The statistically significant decrease of cognitive functions in comparison with control group was revealed at the first visit. The statistically significant regression of cognitive deficit, with the most distinct positive dynamics of frontal functions and semantic verbal fluency, was identified as a result of the treatment. The significant improvement in cognitive evoked potentials in the form of the reduction of P3 latency was recorded after the treatment.

[Cognitive disorders in the early rehabilitation period of ischemic stroke and possibilities of their treatment with neuromidin].

Cognitive functions were assessed in 116 patients, aged from 18 to 84 years, in the early rehabilitation period of the first ischemic stroke of hemispheric localization and in 44 patients with cerebrovascular disorders without history of stroke. MMSE, FAB, CDT, 5 words' test, the Schulte test, verbal fluency test, CES-D were administered. The statistically significant decrease in cognitive functions was seen in the index group compared with the control one. The level of cognitive impairment was correlated with the severity of neurological deficit and age and was aggravated by depression. Neuromidin (ipidacrinum) was used in the treatment of 31 patients in incremental doses (intramuscular injections of 10 mg/day during the first two weeks and later--60 mg/day during 40 days per os). As a result, the significant increase in cognitive function with the recovery of attention, memory and lobe functions was noted.

[Complementary nuclear DNA in embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum]. / Dopolnitel'naia iadernaia DNK v kletkakh zarodyshevykh meshkov Haemanthus albiflos, Ornithogalum caudatum.

Cytophotometric measurements of Feulgen-DNA were carried out in the nuclei of embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum. It was found that the nuclei of the egg system, haploid in the number of chromosomes, became polyploid in DNA amount at the final stages of gametophyte development.
