[Influence of anthropogenic environmental factors on the occurrence of acute ischemic attacks in the population of an industrial town]. / Vliianie antropogennykh faktorov sredy obitaniia na vozniknovenie ostrykh narushenii mozgovogo krovoobrashcheniia u naseleniia promyshlennogo goroda.

An analysis of the incidence of acute ischemic attacks (AIA) has shown its steady rise in the population of Orenburg in 1997-2000, men are 1.8 times more frequently ill than women with a relatively stable growth in both examined groups. Analyzing morbidity rates in age groups (under and above 50 years) has demonstrated a substantial increase in the incidence of AIA in the under 50-year group living in the Industrial District. The blood levels of essential trace elements in patients with AIA are lower than the normal values in the residents of the Industrial and Central Districts.

[The copper content of the blood and skin in children with circumscribed scleroderma]. / Soderzhanie medi v krovi i kozhe detei, bol'nykh ogranichennoi sklerodermiei.

The authors have demonstrated the pathogenetic significance of elevated copper levels in the blood and involved skin in development of collagen metabolism disorders in children suffering from focal scleroderma. A correlation between elevation of blood serum copper level and the skin process dissemination and activity was revealed. Copper concentration in involved skin of these children surpassed 7-fold the normal value.

[Bilateral circumscribed scleroderma of the face in children]. / Bilateral'naia ogranichennaia skleroderma litsa u detei.

Two cases of local scleroderma in children are described with bilateral symmetrical localization of the foci on the face, including a most rare site--round the eyes. A long follow-up of children with such a localization of the disease is necessary, because they may develop Romberg's hemiatrophy.

[The diagnostic importance of research on the lysyl oxidase activity in children with circumscribed scleroderma]. / Diagnosticheskoe znachenie issledovanii aktivnosti liziloksidazy u detei, bol'nykh ogranichennoi sklerodermiei.

Blood serum lysyl oxidase activity considerably varies, these variations correlating with the skin process dissemination, in children suffering from focal scleroderma. This enzyme was undetectable in normal subjects and patients with dermatoses whose clinical symptoms are similar to those of focal scleroderma. Blood serum lysyl oxidase activity elevation is a specific sign, characteristic of patients with focal scleroderma; it therefore may be used for the laboratory diagnosis of this dermatosis, assessment of its dissemination and severity.
