One of the leaved out fault active systems at Southern Moravian can be considered the so called Diendorf - Čebín tectonic zone (DCTZ), that is seismically active in its southern segment (in Austrian). The Waitzendorf fault is a part of the DCTZ, with intensive morphological signs. The terrain recognizance along the eastern margin of the Dyje Dome confirmed many indi cations showing evidence of geodynamic activity. The facets, old land slides and rock falls indicate recent activity in the environs of Znojmo area. The paper offers interpretation of the geodetic results (GPS) using morphological and geophysical data from all area of the DCTZ ., Lubomil Pospíšil, Pavel Roštínský, Otakar Švábenský, Josef Weigel and Michal Witiska., and Obsahuje bibliografické odkazy
Four groups of goldfish were exposed to cadmium in a concentration of 20 mg Cd/l water under aquarium conditions. The duration of exposure was 1, 4, 7 and 15 days. It was shown that the activity of superoxide dismutase (SOD) in the red blood cells (RBC) significantly decreased after the first day of cadmium exposure. However, the SOD activity increased after 7 and 15 days of cadmium treatment. Elevated activity of catalase (CAT) was found in erythrocytes of cadmium-treated fishes after 15 days, whereas plasma GOT levels was increased after 7 and 15 days and GPT levels after 1, 4, 7 and 15 days of cadmium treatment. This was accompanied by a significant decrease of blood hemoglobin concentrations (after 15 days) and hematocrit values (after 7 and 15 days). However, the concentration of blood glucose significantly increased after 1, 4, 7 and 15 days of cadmium exposure. These results indicate that cadmium causes oxidative stress and tissue damage in the exposed fishes., R.V. Žikić, A. Š. Štajn, S. Z. Pavlović, B. I. Ognjanović, Z. S.

Total superoxide dismutase (SOD, EC 1.15.1.1) and catalase (CAT, EC 1.11.1.6) activities in erythrocytes and the glutamic acid-oxalacetic acid-transaminase (GOT, EC 2.6.1.1) and glutamic acid-pyruvic acid-transaminase (GPT, EC 2.6.1.2) activities in the plasma were measured in experimental groups of carps (Cyprinus carpio L.) exposed to cadmium in a concentration of 20 mg Cd/1 water under aquarium conditions for 6, 12, 18 and 24 hours and in control fishes. It was shown that the total activity of SOD in the erythrocytes is significantly decreased after 12, 18 and 24 hours of cadmium exposure. Increased activities of CAT (after 24 hours) in the erythrocytes and GOT and GPT in the plasma were found in cadmium-treated fishes. At the same time the concentration of blood haemoglobin and haematocrit values were significantly diminished. These results indicate that cadmium causes oxidative stress and tissue damage in the exposed fishes.
