[The case of completed pregnancy of the patient with Dandy-Walker malformation]. / Sluchai mal'formatsii Dendi-Uokera s donoshennoi beremennost'iu i rodami.

Dandy-Walker malformation is a rare disease of the central nervous system pathology (congenital malformations of the fossa cranii posterior). The key features of this syndrome are an enlargement of the fourth ventricle; complete absence of the cerebellar vermis, the posterior midline area of cerebellar cortex responsible for coordination of the axial musculature; and cyst formation near the internal base of the skull. Pregnant patients with Dandy-Walker malformation are at high risk and are managed by multidisciplinary teams including neurologists and obstetricians. We present a case report of full-term pregnancy and uncomplicated delivery in a women with Dandy-Walker malformation.

Moya-moya syndrome is a rare chronic genetic disease characterized by progressive cerebral vascular occlusion and progressive stenosis of inner carotid arteries resulting in the frequent ischemic attacks and development of collateral arterial circulation. Pregnant patients with moya-moya syndrome are at high risk due to the development of complications. The authors present a case report of full-term pregnancy in a woman with moya-moya syndrome.

Dependence of the electron-cloud instability on the beam energy.

The electron cloud (EC) can be formed in the beam pipe of a circular accelerator if the secondary emission yield (SEY) of the inner surface is larger than 1, and it can detrimentally affect the circulating beam. Understanding the underlying physics and defining the scaling laws of this effect is indispensable to steer the upgrade plans of the existing machines and the design of new ones. The single bunch EC instability (ECI) is shown to be strongly affected by the transverse beam size. Transversely, smaller beams going through an electron cloud generate higher electron peak densities and lower the intensity threshold to make the beam unstable. In particular, since higher energy beams have smaller transverse sizes (for equal normalized transverse emittances), the scaling of the ECI threshold with the beam energy turns out to be surprisingly unfavorable.

[The effect of the extremely weak field on the cultures of bacteria Escherichia coli and Staphylococcus aureus]. / Deistvie sverkhslabogo polia na kul'tury bakterii Escherichia coli i Staphylococcus aureus.

The effect of extremely weak human electromagnetic field on the suspensions of Escherichia coli and Staphylococcus aureus in a physiological solution at 25 degrees C was studied. The results obtained indicate that the human field induces changes in the physical properties of liquid water in physiological solution and the induced structural and dynamic rearrangements of extracellular water are tranferred to bacterial cells and change their functional activity.

The influence of microwaves, generated by navigation radars, on the animals' behavior, their antioxidant and reproductive systems were studied. It was found that the exposure to power of 1000 (microW/cm2)h exceeded the threshold of harmful action of electromagnetic radiation.

[On health regulation of synthetic detergents]. / K probleme gigienicheskogo reglamentirovaniia sinteticheskikh moiushchikh sredstv.

The authors present materials on hygienic regulation of such synthetic detergents as "Losk", "Dixan" in air of workplace and populated area, demonstrate results concerning evaluation of "Losk" effects. Discussion covers ways to evaluate chemical load caused by simultaneous emission of synthetic detergents from various environmental objects. For testing reliability of hygienic regulation for complex emission exemplified by "Losk", the authors suggest a model for express evaluation of complex exposure to chemicals.

[Experimental research on the effect of the components in household chemical preparations on the body]. / Eksperimental'nye issledovaniia vliianiia nekotorykh sostavnykh komponentov preparatov bytovoi khimii na organizm.

Experiments on animals were conducted to study influence of following household chemical components included into synthetic washing and cleaning mixtures: anion-active surface active substances, protease Blap 200 G, Savinase 4.OT, Purafect 200 G, alkaline proteinase made in Russia, an aromatic "Magic blue". Surface active substances included into synthetic washing and cleaning mixtures were proved to increase biologic activity of chemical components of the mixtures. Powdered anion-active surface active substances, unlike liquid and paste-like ones, require hygienic regulation in air. All new components of synthetic washing and cleaning mixtures should undergo toxicologic and hygienic examination, and require studies on hygienic regulation, if found in concentrations hazardous for health.

Becavior, peripheral blood, biochemical and morphologic parameters were assessed in the laboratory animals exposed. The response appeared to correlate with individual and typologic features of the examinees.

[Standardization of di-chlor-di-para-xylilene, di-bromine-di-para-xylilene and di-para-xylilene]. / Materialy k reglamentirovaniiu di-khlor-di-para-ksililena, di-brom-di-para-ksililena i di-para-ksililena.

Studied were the new components of dielectric coatings: di-para-xylilene, di-bromine-di-para-xylilene, dichlor-di-para-xylilene, which manifested themselves as low-toxicity compounds free from irritating, sensitizing and fibrogenous effects. The acute action thresholds for aerosols of the paraxylilenes were established at 10 mg/m3 (with regard to general and embryotoxicity), at 5 mg/m3 for the maximal inactive concentrations.

[Characteristics of the response of animals of different typological groups to the action of electromagnetic irradiation in the high and superhigh frequency ranges]. / Osobennosti reaktsii zhivotnykh razlichnykh tipologicheskikh grupp navozdeistvie élektromagnitnykh izluchenii vysokochastnogo i sverkhvysokochastnogo diapazona.

Peculiarities in the response of male rats of various typological (e.g. high- and low-entropy) groups to the effect of electromagnetic radiation of high and superhigh frequencies have been investigated. Radiation intensity was 500 microW/cm2 and 500 V/m respectively. Animals of different entropy groups exhibited variations in the radiation response of their CNS and endocrine system as well as in the state of their offspring during the antenatal development.

[Dynamics of the activity of energy metabolism and lysosomal enzymes in experimental atherosclerosis (a quantitative histochemical study)]. / Dinamika aktivnosti énergeticheskikh i lizosomnykh fermentov pri éksperimental'nom ateroskleroze (kolichestvennoe gistokhimicheskoe issledovanie).

A quantitative biochemical study of patterns of energy and lysosomic enzymes in cellular elements of the rabbit aorta under induced atherosclerosis showed these enzymes to be activated during earlier atherogenetic stages associated with the formation of atherosclerotic patches in the intima, an evidence of functional adaptation of the aortal wall building up the defence mechanisms against adversary effects of cholesterol and other lipids. Once marked atherosclerotic patches have been formed in the aorta, adaptive potentials of enzyme systems are exhausted and further changes in their activity can result in processes conducive to the development of experimental atherosclerosis.

[Effect of different types of excessive feeding on the state of vascular walls in rats]. / Vliianie razlichnykh vidov izbytochnogo pitaniia na sostoianie sosudistoi stenki u krys

Immature male rats were overfed for a long time with an excess of fats or carbohydrates; this caused obesity. Carbohydrate overfeeding led to a greater body weight gain and a greater increase in the weight of epididymal fat and of the adipose cell volume than fat overfeeding, but failed to decrease the lipolytic activity of the aorta. Prolonged fat overfeeding decreased the lipolytic activity of the aorta considerably. Thus, the results of the mentioned experiments showed that the predisposition of the aortic wall to atherogenesis did not correlate with the gain in weight and depended on the character of nutrition.
