“…ProntoDry and HpONE had significantly faster mean PRTs than the CLO test. Many published data have reported that the urease testing process (jumbo vs. ordinary forceps and warmed vs. room temperature), location (antrum vs. body), and number of specimens might influence the results of RUTs (13)(14)(15)(16)(17). Because the specimens were taken from the antrum and side by side, the use of different kinds of media may explain the better results of ProntoDry and HpONE than the CLO test, in that the diffusion of urea in agar gel medium is slower.…”

“…The δ 13 CO 2 is the ratio of 13 C to 12 C in the sample, compared with that in the PDB standard, and is expressed by the following equation: δ 13 CO 2 = (R samp − R std )/R std × 1000. R samp and R std represent the ratios of 13 C to 12 C in the test and baseline samples, respectively. Excess δ 13 CO 2 is the value of δ 13 CO 2 detected at 15 min minus that at baseline.…”

“…Die Dokumentation der Abkühlkinetik kann beim Verzicht auf ein geregeltes Einfriergerät, das für den Betrieb in der Regel Flüssigstickstoff erfordert, durch ein Gerät ersetzt werden, welches mit einem Thermofühler den Temperaturverlauf erfaßt und registriert. Dabei ist es nicht wichtig, daß gleichzeitig auch die HES/DMSO-Mischung verwendet wird, denn inzwischen konnte auch mit DMSO allein ein klinisch überzeugender Erfolg nachgewiesen werden [51]. Vielmehr ist wichtig, daß die erforderliche Abkühlkinetik reproduzierbar erreicht wird.…”

“…The best results are obtained with two biopsies: one from the corpus and one from the antrum of the stomach [2]. For RUT to became positive, 1000 to 10,000 colonyforming units (cfu)/mml are necessary [3]. In our study we compared the accuracy of RUT with that of histology one month after antimicrobial therapy.…”
