[Bacterial endotoxins produced by Alcaligenes faecalis and Erwinia herbicola as potential occupational hazards for agricultural workers].

Laboratory animals (guinea pigs and rabbits) were exposed to the inhalation of aerosolized endotoxins derived from the cell mass of Alcaligenes faecalis and Erwinia herbicola, the Gram-negative bacteria commonly occurring in organic dusts. Single 1 hour-lasting exposure caused the significant increase in the number of free lung cell, mostly lymphocytes, compared to the control group exposed to saline (P < 0.001).

[Effect of beta 2-adrenergic agonists on neurotoxic action of aminophyllines].

The purpose of the present investigation was to evaluate whether the beta 2-adrenergic agonists affect the pharmacodynamics and pharmacokinetics of aminophylline-induced seizures. Adult male Albino Swiss mice were treated i.p.

[Blood platelets as one hemostatic indicator in patients with bronchial asthma].

Phospholipids forming blood platelets membrane are substrates for oxidative phosphorylation in electric and chemical activation of these cells. Beneficial effect of corticosteroids on the course of asthma is connected with inhibition of phospholipase A2. This enzyme is responsible for the generation of allergic reaction membrane mediators like leukotrienes, prostaglandins and other lipoxygenase products.

[Phenotype of lymphocytes in bronchoalveolar lavage and peripheral blood with different clinical presentations of sarcoidosis].

The aim of this study was to investigate the relationship between the bronchoalveolar cell counts, the phenotypic characteristics of bronchoalveolar lavage and peripheral lymphocytes and the clinical manifestation of sarcoidosis. 24 patients with sarcoidosis of the lung were examined. Patients were divided into groups based on the presence and the type of clinical symptoms (patients with symptoms of Löfgren syndrome, with constitutional and respiratory symptoms and symptomless patients).

[Cytologic and histopathologic examinations of polyps and mucosa in chronic allergic and nonallergic rhinitis].

We evaluated cytograms and tissue sections of nasal polyps and mucosa of 30 patients with chronic allergic and nonallergic rhinitis. We compared them with cytograms and biopsies of 20 asymptomatic persons. We noticed a presence of neutrophils in cytograms and in biopsies of patients with allergic rhinitis and with nonallergic eosinophilic rhinitis.
