[Tissue factor and tissue factor pathway inhibitor during specific bronchial challenge in allergic asthma patients].

Allergic asthma is characterized by bronchial inflammation and repair processes at the same time, that cause increased airway obstruction. Recent evidences suggest that monocytes and macrophages may play important role in allergic inflammation. Activated by proinflammatory factors they can express tissue factor (TF) and tissue factor pathway inhibitor (TFPI).

Endothelial cells and angiogenesis intensity in lung cancer.

We focused our studies on single endothelial cells (ECs) scattered in extracellular matrix in lung cancer tumors. Neovascularization was evaluated in 100 tumors obtained from patients operated for lung cancer, in relation to histological type, tumor differentiation and clinical stage of the disease. Angiogenic objects (single endothelial cells and microvessels) were identified by immunohistochemistry using monoclonal antibodies against von Willebrand factor.

[Expression of adhesion molecules LFA-1 (CD11a and ICAM-1 (CD54) on lymphocytes and chemokines IL-8 and MCP-1 concentrations in bronchoalveolar lavage of patients with asthma or chronic obstructive pulmonary disease].

Chemokines and cellular adhesion molecules are crucial determinants of the migration of immune effector cells to the tissues asthma and chronic obstructive pulmonary disease (COPD) are a complex of conditions, which have airflow limitation in common. The aim of this study was to determine the numbers and percentages of lymphocytes expressing adhesion molecules: LFA-1, ICAM-1 together with assessment of chemokines concentrations: IL-8 and MCP-1 in bronchoalveolar lavage fluid (BAL) of patients with asthma or chronic obstructive pulmonary disease (COPD). 12 patients with asthma, 14 patients with COPD, and 6 subjects of control group took part in this study.

[The effect of local specific bronchial immunotherapy (LIT) on specific and non-specific bronchial hyperreactivity in patients with bronchial asthma sensitive to housedust mites].

The aim of the study was to evaluate the effect of LIT with mite allergens given by dry powder inhalation on bronchial hyperreactivity after histamine and allergen inhalation in patients suffering from atopic mite asthma. The study was conducted in a group of 17 asthmatics (9 patients Hypoinhal Dermatophagoides, 8 patients placebo). A decrease in specific (early asthmatic reaction during specific bronchial provocation test) and non-specific bronchial hyperreactivity has been revealed in the group treated with Hypoinhal Dermatophagoides.
