Cadmium ions adsorb onto calcium hydroxyapatite crystals (HA) and are as effective as inorganic pyrophosphate and aluminum ions in retarding the rate ofin vitro dissolution of HA. In contrast, cadmium ions have no important retarding effect on the growth of HA, but are built into the crystals, thus making them very resistant to subsequent dissolution. These(More)
Nasal polyposis is a result of a chronic inflammatory disorder in the upper airways. In vitro studies have revealed that extravasation of leucocytes requires interactions between several sets of adhesion molecules expressed on the circulating leucocytes and the vascular endothelium. Therefore, the endothelial expression of intercellular adhesion molecule-1(More)
Infiltration of eosinophil granulocytes and endothelial expression of vascular cell adhesion molecule-1 (VCAM-1) and P-selectin was investigated in biopsies of polyps and inferior turbinates from 16 patients with nasal polyps, by the use of immunohistochemical staining and stereological quantification before, during and after topical treatment with(More)
Human mast cells can be divided into two subtypes: MCTC cells, which contain tryptase and chymase, and MCT cells, which contain tryptase only. Herein we have used a combination of histamine, tryptase and chymase immunohistochemistry as a novel approach to the study of mast cells. Using this technique, we have discovered a new type of MCTC mast cell in(More)
In this report we have reviewed studies on the clinical effect of the interferon (IFN) treatment of 304 patients suffering from cutaneous T-cell lymphoma (CTCL). Intramuscular, subcutaneous or intralesional administration of recombinant IFN has been used as monotherapy or as part of combination therapy. In general, IFN has proved to be a relatively(More)
Chronic maxillary sinusitis is a common condition. The disease is most often caused by blockage of the sinus ostia or presence of an oroantral fistula. We report two cases of unilateral chronic maxillary sinusitis associated with foreign bodies in the maxillary sinus. In the first case the foreign body consisted of dental amalgam, in the second case of two(More)
OBJECTIVE The expression of some growth factors in nasal polyps has been examined, although investigations addressing the reason for recurrence in some patients are lacking. Vascular endothelial growth factor (VEGF) is expressed by inflammatory cells, as well as by endothelial and epithelial cells of nasal polyps. To determine whether VEGF may play a role(More)
The present study comprised macro- and endoscopic screening of the nasosinusal complex in 56 autopsies, 24 with nasal polyps and 32 without. Seven had nasal polyposis (bilaterally more than two). Hypertrophic polypoid mucosa in the paranasal sinuses was not found in the cases with nasal polyposis and in only 2 (4%) of the total number (24) of cases with(More)
Various growth factors are expressed in nasal polyps, and some of these have been suggested to play a role in polyp formation. A potential relation between growth factor expression and polyp recurrence, however, is undetermined. Basic fibroblast growth factor (bFGF) is expressed in mononuclear cells, as well as in endothelial and epithelial surface and(More)
