Journal article (peer-reviewed)abstract
- Fourteen patients with Helicobacter pylori infection were treated with 20 mg omeprazole, 1 g amoxycillin and 400 mg metronidazole bd for 7 days (OAM), and 16 patients were treated with 20 mg omeprazole, 250 mg clarithromycin and 400 mg metronidazole bd for 7 days (OCM). Saliva, gastric biopsies and faecal samples were collected before, during (day 7) and 4 weeks after treatment in order to analyse alterations of the normal microflora and to determine antimicrobial susceptibility. Both treatment regimens resulted in marked quantitative and qualitative alterations. A selection of resistant streptococcal strains were noticed in both treatment groups, most apparent in the OCM group where a shift from susceptible to resistant strains was recorded. In the OAM group, six patients had overgrowth of resistant Enterobacteriaceae during treatment compared with none in the OCM group, in the gastric microflora. The MICs for Enterococcus spp. and Enterobacteriaceae in faeces increased significantly during treatment in both groups. Nine patients in the OAM group became intestinally colonized by yeasts during treatment. The total anaerobic microflora was strongly suppressed in both treatment groups, although most pronounced in the OCM group, where the frequency of clarithromycin-resistant bacteroides strains increased from 2 to 76% during treatment, and remained at 59% 4 weeks post-treatment. Even if the treatment outcome was better in the OCM group (100%) than in the OAM group (71%), the amoxycillin-based treatment might be preferable from an ecological point of view, since the qualitative alterations in terms of emergence and persistence of resistant strains seemed to be most pronounced in the clarithromycin-treated group.

Development and psychometric properties of the Emotional State Questionnaire : a self-report questionnaire for depression and anxiety
- 1999

Journal article (peer-reviewed)abstract
- Anxiety and depression are dimensions of emotional state that can be validly assessed with self-report measures. This article introduces a new self-report questionnaire for depression and anxiety (Emotional State Questionnaire (EST-Q)) and presents data on its reliability and validity. The items of the EST-Q were derived from diagnostic criteria of DSM-IV and ICD-10. Thirty-three items were rated on a five-point frequency scale. The questionnaire was administered to 194 inpatients with depressive and anxiety disorders and to a population sample of 479 subjects. According to the results of factor analysis, five subscales were formed: Depression, Anxiety, Agoraphobia-Panic, Fatigue, and Insomnia. EST-Q and subscales showed acceptable internal consistency (alpha = 0.69-0.88). Significant differences in subscales between patients and population and across diagnostic groups confirmed the discriminant validity of the instrument. Depression, Anxiety, and Agoraphobia-Panic subscales distinguished corresponding diagnostic groups. Fatigue and Insomnia appeared to assess nonspecific psychopathology dimensions characteristic of several psychiatric disorders.

Radiation and hypothermia: changes in DNA supercoiling in human diploid fibroblasts
- 1999
-
In: Anticancer Res. - 0250-7005 .- 1791-7530. ; 19:6B, s. 5307-11

Journal article (peer-reviewed)abstract
- The influence of hypothermia (2 degrees, 15 degrees and 28 degrees C) upon the effect of X-irradiation on chromatin from human diploid fibroblast cells (AG1518) was studied using the fluorescent halo assay. Rewinding of supercoils was inhibited in a dose-dependent manner when cells were irradiated with 4, 8 or 16 Gy. This inhibition of rewinding was reduced when cells were irradiated at subnormal temperatures compared with cells irradiated at 37 degrees C. One hour's preincubation at low temperature did not influence rewinding. When AG1518 cells were irradiated at 37 degrees C in the presence of the radical scavenger DMSO (0.5 M), the radiation-induced damage was reduced. No additional protection of DMSO in hypothermic cells (2 degrees C) was found, possibly indicating that OH-radical-mediated effects are more temperature dependent. These results are similar to those recently found for the malignant MCF-7 cell line.
