[Autoantibodies to α7-subunit of neuronal acetylcholine receptor in children with traumatic brain injury].

An objective of the study was to search for new biologically significant markers of brain damage. Levels of blood serum autoantibodies (aAB) to different fragments of α7-subunit of acetylcholine receptor (ACR) were studied in children with traumatic brain injury of different severity. The more severe was trauma, the higher was the level of aAB to fragments of α7-subunit of ACR in the first week after trauma.

[S100B protein and autoantibodies to S100B protein in diagnostics of brain damage in craniocerebral trauma in children].

Levels of antibodies AB (AB) to S100B and S100B protein were studied in the blood serum of children with different severity and outcomes of traumatic brain injury (TBI) from the 1st to 15-75th days after TBI. Severity and outcomes were assessed using the Glasgow Coma Scale (GCS). Patients were stratified by outcomes into the following groups: complete recovery (group 1), moderate disability (group 2), high disability (group 3), vegetative state (group 4) and fatal outcome (group 5).

Morphofunctional study of the therapeutic efficacy of human mesenchymal and neural stem cells in rats with diffuse brain injury.

We studied the effect of transplantation of human stem cells from various tissues on reparative processes in the brain of rats with closed craniocerebral injury. Combined treatment with standard drugs and systemic administration of xenogeneic stem cells had a neuroprotective effect. The morphology of neurons rapidly returned to normal after administration of fetal neural stem cells.

Autoantibodies to glutamate receptors and products of nitric oxide metabolism in serum in children in the acute phase of craniocerebral trauma.

Levels of serum autoantibodies (aAb) to glutamate receptors and products of nitric oxide (NO) metabolism, i.e., nitrates and nitrites, were assayed in children with recent craniocerebral trauma (CCT) of different levels of severity.

[Autoantibodies to glutamate receptors and metabolic products of nitric oxide in blood serum of children in the acute period of brain trauma].

Autoantibodies (AB) to glutamate receptors of AMPA (Glur1) and NMDA (NR2A) types and nitric oxide metabolites, nitrates and nitrites (NOx), were studied in the blood serum of children with brain trauma of different severity. The level of both AB types increased from the 1st to the 10th day after trauma. The level of NMDA (NR2A) AB was higher comparing to AMPA (Glur1).

Glutamate receptor autoantibody concentrations in children with chronic post-traumatic headache.

We report here studies on the levels of autoantibodies (aAb) to AMPA glutamate receptors (GluR1 subunit) and NMDA glutamate receptors (NR2A subunit) in serum from 60 children aged 7-16 years with chronic posttraumatic headache (CPTHA) following mild craniocerebral trauma (CCT). The first group consisted of 48 children who had sustained cerebral concussion (CC), of which 34 had single-episode CC (subgroup 1a) and 14 had repeated CC (subgroup 1). The second group included 12 children with mild cerebral contusions (MCC).

Morphofunctional study of the therapeutic effect of autologous mesenchymal stem cells in experimental diffuse brain injury in rats.

Effects of systemic transplantation of mesenchymal stem cells obtained by culturing of autologous bone marrow on proliferative activity of cells and functional morphology of neurons after diffuse brain injury were studied in Wistar rats. Comparative analysis of the results indicated that systemic injection of mesenchymal stem cells in a syngeneic organism produced proliferotropic, angiogenic, and, presumably, neurotrophic effects. The therapeutic effect visually manifested on day 2 after intravenous injection of mesenchymal stem cells during the early period of reparative regeneration of ischemic cell and tissue structures of the brain.

[Autoantibodies to glutamate receptors in children with chronic posttraumatic headache].

Autoantibodies (aAB) to AMPA (Glu R1 subunit) and NMDA (NR 2A subunit) glutamate receptors were studied in blood serum of 60 children, aged 7-16 years, with chronic posttraumatic headache after mild skull injury. All the children were divided into 2 groups: group 1 included 48 children with concussion of the brain, group 2--12 children with brain contusion. Group 1 was divided into 2 subgroups: subgroup 1a comprised 34 children with single concussion and subgroup 1b--14 children with repeated concussion.

[Concurrence of Fahr's disease with cerebellar tumors].

Fara's disease or idiopathic calcification of the basal ganglia is a rare disease that is characterized by multiple petrificates in the area of the basal ganglia, caudate nucleus, and dentate nuclei of the cerebellum. As of now, only two cases of a concurrence of Fara's disease and brain tumors have been described. The authors present two more cases.

[Lipid peroxidation in the cyst fluid of craniopharyngiomas].

Comparing of the craniopharyngiomas cyst fluid, collected during the surgery, with blood plasma revealed significantly enhanced lipid peroxidation and lactate accumulation in tumour cysts contents. These processes were usually more prominent in endosuprasellar than in suprasellar craniopharyngiomas. The maximum of free radical formation in conjunction with the lowest level of malondialdehyde (MDA) was observed in primary tumours with relatively high proliferation rate.

[Single-photon emission-computed tomography of the brain in craniopharyngiomas in the late postoperative period].

The paper analyzes tomographic scanning images of 32 patients with craniopharyngiomas in the late postoperative period. Computed tomographic data allowed the patients to be divided into 3 groups: 1) 10 patients without signs of tumor recurrence or hydrocephalus; 2) 14 patients with recurrent cystic craniopharyngiomas; 3) 8 patients with severe hydrocephalus. Single photon emission computed tomography (SPECT) of the brain indicated regional disturbances of brain tissue blood supply in the frontobasal or frontobasotemporal regions of the right hemisphere (the area of an surgical access and of the removed tumor) and revealed them in the distal areas (frontobasotemporal regions of the left hemisphere, parietal and occipital cortices of the cerebral hemisphere or cerebellar tissue).
