Impact of World Thrombosis Day campaign.

Thrombosis is an underlying cause of one in four deaths globally. The International Society on Thrombosis and Haemostasis established the inaugural World Thrombosis Day on October 13, 2014. The World Thrombosis Day campaign aims to 1) highlight the disease burden from thrombosis, 2) increase public awareness of the risks, signs, and symptoms of thromboembolic conditions, 3) empower individuals to discuss their thrombosis risk with their healthcare provider, 4) galvanize organizations across the globe, and 5) advocate for "systems of care" to prevent, diagnose, and treat venous thromboembolism and atrial fibrillation.

[The course of twin pregnancy and delivery in a woman after mitral valve implantation].

We described the course and the way of twin delivery of patient, who was pregnant one month after implantation of mitral heart valve. We discussed the threats for the fetus and mother, connected with administration of anticoagulant drugs.

[Activity of superoxide dismutase and its isoenzyme during normal pregnancy].

High activity of SOD was found in erythrocytes and blood plasma in 38-40 weeks of uncomplicated pregnancy. Changes of SOD isoenzymes in blood plasma were found in course of pregnancy.

[Activity of superoxide dismutase (SOD) and its isoenzyme activities in newborn children and adult women and men].

During fetal development, antioxidant defense mechanisms have generally been considered to be less active than those of mature newborn infants or of the adults. It has been suggested that this might reflect a lower requirement for cellular antioxidant activity because of the relatively protective intrauterine environment and the lower perfusing oxygen tension in the fetus. Inadequate antioxidant protection has been postulated as a prime factor in pathologic states such as bronchopulmonary dysplasia and retinopathy in preterm infants.

[Antioxidant agents--importance in neonatology].

The toxic consequences of oxygen therapy may be development some neonatal diseases, for example: retrolental fibroplasia and bronchopulmonary dysplasia. It's now generally believed that oxygen induced cell toxicity is the result of formation of highly reactive free radicals. The greater incidence of these disorders in preterm infants suggest that some aspect of prematurity increases susceptibility of effects of toxic oxygen species.

[Monoamine oxidase (MAO) activity in the liver and brain of guinea pigs exposed to an electric field of industrial frequency].

The activity of MAO has been determined in the brain and liver of 36 male guinea-pigs. The animals have been exposed to electric fields of 50 Hz and 100 kV/m frequency. The guinea-pigs have been divided into the following groups (12 animals each): group I--every day 4 hrs' exposure to electric fields (total dose--100 hours), group II--4 hrs' exposure every other day (total dose--100 hours), group III--4 hrs' exposure every third day (total dose--100 hours).
