RESUMO

The purpose of this study was to give the description of harmful effects of the impact of electromagnetic radiations from base stations of cellular communication as the most common sources of radio frequencies of electromagnetic fields in the environment. The highest values of the energy flux density were measured on the roofs of houses where antennas are installed - more than 10 pW/cm. The lowest values were recorded in inside premises with expositions of 0.1-1 pW/cm. In the close location of the railway station to the base stations of the cellular communication there was seen a cumulative effect. There are proposed both new safe hygienic approaches to the control for the safety of the work of base station and protective measures.

RESUMO

Effects of space flight on growth and biosynthetic features of plant cells were studied in two strains of ginseng (Panax ginseng) differing in growth and particularly biosynthetic activities, a strain of Lithospermum Erythrorhizon and a strain of Macrotomia Euchroma which produce biologically active naphroquin-derived pigments. --and also differ in growth and biosynthetic properties. Following exposure aboard MIR and a Space shuttle, cells of the callosal cultures were subjected to callosal or suspension passaging. Biomass yield and biologically active substances--ginseng saponins ginsenoids and shikonin were determined in the cells cultures. There was no evidence for the biomass yield to be significantly altered by space flight; however, the content of biologically active substances was materially changed with the strain.

RESUMO

Changes in the blood clotting system and rheology were studied in 39 patients during reconstructive operations making use of microsurgical methods. Effects of various doses of water soluble acelysine, an acetylsalicylic acid preparations (DL-lysine acetylsalicylate and glycine) have been evaluated during surgery and the immediate postoperative period. Clinical and laboratory changes in blood coagulation were determined at different doses (1000, 500, and 250 mg). Even in low doses (3.94 +/- 0.25 mg/kg) acelysine ensured chronometric and structural hypocoagulation as early as 1 h after dosed infusion and throughout the entire intervention, preventing thrombosis of microvascular anastomoses. Administration of acelysine in doses higher than 250 mg is not recommended, because higher doses involve the risk of hypocoagulation complications.

RESUMO

The impact of various infusion therapy techniques has been studied in 166 patients during microsurgery for posttraumatic tissue defects. It has been established that the achievement of hypervolemic hemodilution is accompanied by the damage of water-electrolyte homeostasis and peripheral circulation during the operation and on the first postoperative day. Normovolemic hemodilution makes it possible to prevent the above disturbances and optimize peripheral blood flow in case the infusion programme is compiled adequately with an obligatory introduction of blood plasma preparations.

RESUMO

By means of ultrasonography the common carotid artery and the internal jugular vein at certain sports have been investigated. In swimmers the internal jugular vein is essentially dilated as compared to the common carotid artery. In high jumpers there is not any noticeable differences between the width of the artery and the vein. These data should be taken into account at training sportsmen. They are also important for development of investigations in the ultrasound anatomy.
