[en] A windowless through-flow gas detector is used for measurement. The automatic machine is controlled by four flip-flops defining the following states: the dish replacement in the measuring space, washing, measurement, measured value print-out, and resetting. The first and second outputs of the first, second and third flip-flops are connected to six inputs of a block whose four outputs provide counter reset and stop-watch reset, washing, measurement, and print-out. Such machine control eliminates measurement errors by disabling sample measurement until air is removed from the measurement space, introduced on an unwashed dish or on several dishes passed under the detector. The elimination of this error is also guaranteed in manual operation. (M.D.)

[en] Cis-diamminedichloroplatinum (Cisplatin) nephrotoxicity and its prevention by hydration in experimental pigs was studied by laboratory and pathomorphological examinations and by isotope renography. In total, 33 renographic examinations were performed in 14 pigs. The comparison of these renographs with the laboratory and post-mortem pathomorphological examinations showed that all findings were in good agreement. Only in exceptional cases was there a discrepancy between the pathological renograph and the kidney damage. The use of isotope renography as a progressive complementary method of kidney function examination was fully proved on condition that maximum immobility of pigs is secured. (author)
