The intracranial B-waves' amplitude as prognostication criterion of neurological complications in neuroendovascular interventions.

The purpose of this study was to evaluate dynamics of B-waves' amplitudes (BWA) of blood flow velocity (BFV) in patients with cerebrovascular diseases during endovascular operations. We examined 12 patients with neurovascular pathology during neuroendovascular interventions. Patients were divided into two groups: 1st group (6 cases)--without intraoperative neurological complications, 2nd group (6 cases)--with complications. Bilateral monitoring of BFV in middle cerebral arteries was carried out applying Multi Dop X. To estimate BWA Fourier analysis was used. In the 1st group preoperative BWA on the affected side was 3.9 +/- 0.6 cm/s. Intraoperative (during an access to pathologic formation and its embolisation) BWA increased up to 7.7 +/- 1.1 cm/s (p < 0.05). Postoperative BWA decreased to 4.2 +/- 0.8 cm/s. In the 2nd group the preoperative BWA on the affected side was 9.6 +/- 1.1 cm/s (p < 0.05), thus higher than in the 1st group. Intraoperatively we observed further increase of BWA up to 12.1 +/- 2.6 cm/s, accompanied by occurrence or increase of neurological symptoms. Postoperative BWA decreased to 10.4 +/- 2.9 cm/s, whereas we didn't observe regression of neurological symptoms.

[Fibronectin and pregnancy].

Fibronectin is a high-molecular polyfunctional glycoprotein occurring in the majority of the body fluids and tissues. Various investigations have demonstrated that plasma fibronectin levels either fail to change, or increase with longer gestation during a normal pregnancy. The time course of changes in fibronectin levels has been found to become lower in the amniotic fluid during pregnancy, though its physiological role has not been defined in this case. In late gestosis, plasma fibronectin concentrations substantially rises as compared to those observed in normal pregnancy.

[Physical development and hematologic and enzymatic status of schoolchildren in a southern city with chemical and oil industries].

It has been found out, that under exposure to atmospheric discharge from chemical and oil-chemical enterprises school-age, children shown disorganization of the activity of nicotineamidadenindinucleotidediaphorase, cytochrome oxidase, acid and alkaline phosphatase in leucocytes, damage of lysosomal membranes of these cells, changes in erythrocytic system and in blood coagulation, shifts in total body sizes and subskin fat deposition in certain age-sex groups, disturbance in the structure of correlational interrelations of enzymocytochemical, hematological and anthropometric + indices etc. The observed deviations in school-age children health status are considered to be prepathological disturbances.

[Anthropometric, hematologic and cytochemical parallels in schoolchildren with normal and abnormal physical development].

The study was undertaken to analyze correlation of 25 indicators characterizing schoolchildren's health status from the cell level up to the body one. There were established some characteristics of forming inner damaging mechanism appearing in the body because of deviations in children's physical development. Body weight deficiency was characterized by high integration of diverse signs, whereas excessive body weight was accompanied by sharp discoordination of interlevel interaction. Low stature was described by links' desynchronization at the cellular and tissue levels that was accompanied by a rupture of relations of the functional systems of the given order with the body level, here interlevel links were indirectly supported.

[Temporal arterial clipping and autoregulation of cerebral blood flow at surgery for intracranial aneurysms].

Preoperative dynamic autoregulatory responses in 20 patients considered as candidates for vessel temporal clipping (TC) and/or arterial hypotension (AH) at surgery for aneurysms were studied by the thigh cuff method. Normal autoregulatory responses at a regulation rate (RoR) of 20.4 +/- 2.8%/s were found in 10 patients > 30 days after subarachnoidal hemorrhage (SH) while RoR was 12.5 +/- 2.5%/s in 10 other patients (30 days, grade III WFNS showed autoregulation impairment. TC and/or AH were proceeded in 17 operated patients. One postoperative death was due to pulmonary embolism. Two poor results with persistent neurological disorders at discharge were associated with TC but in 1 patient. This patient had severe vasospasm and the lowest RoR (9%/s). There were no TC and/or AH postoperative complications in other 14 patients. All of them and 3 other patients with direct aneurysm clipping had a fair outcome.
