The influence of magnetic fields of moderate intensities (50 and 120 Oe) was studied in rats after single or repeated exposures with or without a rise in environmental temperature. The following parameters were investigated: the number of erythrocytes and leucocytes, the percentage of different varieties of leucocytes, serum Na+ and K+, plasma(More)
Rats on board the Soviet Cosmos 936 satellite for l8 1/2 days showed a decreased glycoprotein secretion from the salivary mucous glands, stomach and intestine, and an increased leucine aminopeptidase and acid phosphatase content from the small intestine. Grimelius positive cells were activated. One group of rats were centrifuged at 1 g during the flight to(More)
Changes in some digestive enzymes (amylase, lipase, uropepsinogen) were studied in the serum and urine of one of the participants in the Soviet-Romanian seven-day space flight on the Soyuz 40-Saliut 6 complex. On the first day after landing it was found an increased total serum and urinary amylase, resulting from the separate increase of pancreatic and(More)
Coagulation and fibrinolysis were studied in rats exposed to hypokinesia (HK) obtained by including rats (for 1, 2 and 3 weeks) in small cages designed to limit their movements, permitting only spontaneous feeding (a method widely used for mimicking space flight conditions). The number of thrombocytes, the Quick time, the Howell time and the euglobulinlysis(More)
The paper presents some of the main scientific results achieved in the framework of a recently completed NATO Science for Peace and Security research project. The project aimed to harmonize the different seismic hazard maps of Romania, Moldova and Bulgaria and to develop standard maps in Eurocode 8 format, reflecting the real trans-boundary geophysical(More)
Exposure of rats to an environment of +40 degrees C that increases central (rectal) temperature to about 40 degrees C, importantly decrease the number of thrombocytes, the blood coagulation (the Quick time and Howel time) and euglobulin lysis time (ELT). In order to search for the mechanism responsible for coagulability and fibrinolysis we studied the(More)
Hypokinesia produced specific reactions in tissues related to motion (bones, skeletal muscles and myocardium) and nonspecific in others, as that of the digestive tract after 7 days of hypokinesia. A decreased content of glycoproteins from mucous salivary glands, stomach, small intestine and colon, and an increased intestinal content of(More)
