- OBJECTIVES: To ascertain whether patients with Crohn's disease treated with azathioprine maintained bone mineral mass better than patients treated with steroids alone. DESIGN: Retrospective study. SETTING: University Hospital of Malmo, Sweden. SUBJECTS: A total of 59 patients with ileocolonic, ileocaecal or colonic Crohn's disease. METHODS: Bone mass was assessed by dual photon X-ray absorptiometry at the level of L2-L4. RESULTS: Patients treated with a high lifetime dose of steroids (> 5 g prednisolone) had significantly (P = 0.011) lower Z-score of L2-L4 (-0.87 +/- 1.11; 11 SD) than steroid-treated patients, who had received a low dose of prednisolone (< 5 g) (0.08 +/- 1.16 SD). Azathioprine did not negatively influence the steroid effect on bone mineral density. CONCLUSIONS: Azathioprine does not seem to affect bone mineral density by itself. However, by being steroid-saving, it seems to conserve bone mineral mass in patients with Crohn's disease.

- OBJECTIVE: The aim of this study was to determine whether bone quality, as assessed by osteometry and histologic parameters, can be used to predict implant integration in conjunction with maxillary sinus reconstruction. STUDY DESIGN: Twelve patients with severely atrophied maxillary alveolar processes were treated through use of a two-stage surgical reconstructive strategy with implant placement 4 months after bone grafting. Bone biopsy specimens taken from the iliac crest peroperatively and from the sinus inlay sites 1, 2, 4, 6, or 12 months postoperatively were analyzed by light microscopy and osteomorphometry. Bone mineral content was measured by osteometry. RESULTS: Osteometric and osteomorphometric data (trabecular bone volume [%], assessment of chromatin staining, and an osteocyte index) registered for the biopsy specimens were not statistically correlated with implant failure. CONCLUSIONS: Prognostic evaluation of implant survival is difficult. The tested methods did not contribute to the improvement of guidelines for the clinical handling of these patients.

Failure to detect Chlamydia trachomatis in cell culture by using a monoclonal antibody directed against the major outer membrane protein
- 1997

Ingår i: Journal of Clinical Microbiology. - 0095-1137 .- 1098-660X. ; 35:10, s. 2679-2680

- Two commercially available monoclonal antibodies for cell culture confirmation of Chlamydia trachomatis were compared in two prospective studies and one large retrospective study. In total, more than 33,000 genital specimens were cultured in parallel and stained with both antibodies, one of which was directed against the major outer membrane protein (MOMP) and one uf which was directed against the lipopolysaccharide (LPS). We found the anti-LPS-based assay to be more sensitive and as specific as the anti-MOMP-based assay for C. trachomatis cell culture confirmation of genital specimens.

Circulating cell adhesion molecules in bronchial lavage and serum in COPD patients with chronic bronchitis
- 1994

Tidskriftsartikel (refereegranskat)abstract
- The initial phase of inflammation in bronchial asthma appears to be triggered by the expression of leucocyte-endothelial adhesion molecules on endothelial cell surfaces. Cell adhesion molecules (CAMs) cause adhesion of leucocytes to the endothelium prior to their subsequent extravasation into inflamed tissue. We wanted to determine whether circulating intercellular adhesion molecule-1 (cICAM-1) and circulating E-selectin (cE-selectin) could be detected in bronchial lavage fluid and serum in patients with stable chronic obstructive pulmonary disease (COPD) and chronic bronchitis. Bronchoscopy and small volume bronchial lavage was performed in 19 patients with COPD and chronic bronchitis and in 13 control subjects. We found increased mean levels of cICAM-1 both in serum (481 micrograms.l-1) and in bronchial lavage (24 micrograms.l-1) in the COPD patients as compared to the controls (321 micrograms.l-1 in serum, 15 micrograms.l-1 in lavage). We also found higher mean levels of cE-selectin in serum from the COPD patients (86 micrograms.l-1) compared to controls (50 micrograms.l-1). The serum levels of cE-selectin correlated significantly with lung function measured as forced expiratory volume in one second (FEV1) in percentage of predicted. Patients with significant intrabronchial bacterial colonization had increased levels of serum cE-selectin. Our results indicate that cCAMs may reflect an upregulation of CAMs on endothelial and epithelial airway cells in COPD.

Inhibition of kainic acid binding to glutamate receptors by extracts of Gastrodia

Tidskriftsartikel (refereegranskat)abstract
- S-(4-hydroxybenzyl)glutathione was isolated as the major principle responsible for the inhibition of the in vitro binding of kainic acid to brain glutamate receptors by water extracts of the plant Gastrodia elata. The affinity (IC50 value) of the compound is slightly lower compared to glutamate and glutathione.

Minor components with smooth muscle relaxing properties from scented myrrh (Commiphora guidotti)

- All sesquiterpenes present in a sample of scented myrrh were isolated and characterised. Seven compounds, with cadinane, guaiane, oplopane, and eudesmane skeletons, were obtained, of which two are new and two are reported from a natural source for the first time. The major component, T-cadinol, has previously been shown to possess smooth muscle-relaxing properties, and the major purpose of the investigation was to compare the effects of the minor and more polar sesquiterpenes with that of T-cadinol in the rat aorta. Like T-cadinol, the minor sesquiterpenes are more efficient in reducing K(+)-induced contractions than those induced by the alpha-adrenoceptor agonist phenylephrine, however, they were all less potent than T-cadinol.

Inflammatory reactions from organic pigments in red tattoos
- 1991
-
Ingår i: Acta Dermato-Venereologica. - 1651-2057. ; 71:1, s. 70-73
-
Tidskriftsartikel (refereegranskat)abstract
- Two different red pigments used for tattooing were found to give rise to inflammatory reactions in the skin. No inorganic component was found in the pigments. NMR and MS analyses elucidated the molecular structures of two different organic compounds. A bright red pigment was found to be an aromatic azo-derivative, and a red-violet pigment was found to be linear quinacridone. A strong exposure to UV-light was reported in most cases prior to the onset of the inflammation.

Tidskriftsartikel (refereegranskat)abstract
- A 55-year-old woman developed an airborne dermatitis on her face. Patch testing was performed and showed positive reactions to formaldehyde, thiuram mix, carba mix, and nickel sulphate. She operated a machine at work in which polyacetal granules were heated. The presence of formaldehyde in the pyrolysis smoke from the polymer was confirmed by chemical analysis.
