[Clinical evaluation of intestinal absorption and use of potassium iodide in order to increase effectiveness of therapeutic measures in pneumoconiosis of coal miners].

Numai utilizatorii înregistrați pot traduce articole

The article deals with the effectiveness of alimentary enterosorbents (apple paste fibres) and iodine preparations (potassium iodide) in the complex treatment of pneumoconiosis-diseased miners. The use of the substances in combination with routine drug therapy increased the effectiveness of the

Upregulated has-miR-4516 as a potential biomarker for early diagnosis of dust-induced pulmonary fibrosis in patients with pneumoconiosis.

Numai utilizatorii înregistrați pot traduce articole

Background: Pulmonary fibrosis (PF) is a representative pathological change in patients with pneumoconiosis; however, due to the absence of reliable and early biomarkers, microRNAs have recently emerged as potential candidates for identification. Objectives: The aim of our study was to discover the

Silicate pneumoconiosis in hens.

Numai utilizatorii înregistrați pot traduce articole

Thirteen cases of silicate pneumoconiosis in 3- to 4-year-old hens are described. Ten of the birds were raised in the suburbs of a city near several chalk quarries and two cement-works; the remaining three hens (aged 3 years) had lived in an environment with high particulate pollution from a nearby

Silicate pneumoconiosis in pigs: optical and scanning electron microscopical investigations with X-ray microanalysis.

Numai utilizatorii înregistrați pot traduce articole

Four cases of silicate pneumoconiosis are described in pigs raised near several chalk quarries and two cement works. The pulmonary changes were characterized by thickened alveolar septa, resulting in distorted airspaces, and small foci of initial fibrosis. In the bronchiolar and alveolar sites, as

Comparative pathology of silicate pneumoconiosis.

A simple pneumoconiosis with lamellar birefringent crystals was observed in animals dying in the San Diego Zoo. We studied 100 autopsies from 11 mammalian and eight avian species. In mammals, mild pulmonary lesions comprised crystal-laden macrophages in alveoli and lymphatics. Interstitial fibrosis

Silicate pneumoconiosis of farm workers.

Numai utilizatorii înregistrați pot traduce articole

Abnormal numbers of birefringent particles have been found in the lungs of seven patients (five vineyard workers, one farmer, and one rural resident) in association with a spectrum of early to late interstitial inflammation and fibrosis. Nodular granulomas of the type seen in silicosis were absent.

Rheumatoid pneumoconiosis in a dolomite worker: a light and electron microscopic, and X-ray microanalytical study.

Numai utilizatorii înregistrați pot traduce articole

A 46-year-old woman suffering from rheumatoid arthritis developed numerous round opacities at the apex of the right lung 11 years after an exposure to dolomite . Resected lung showed discrete nodules, 0.8-2 cm in diameter, with central necrosis surrounded by palisading fibroblasts and a prominent

Silicate pneumoconiosis in camels (Camelus dromedarius L.).

Numai utilizatorii înregistrați pot traduce articole

In a random screening of camel diseases in Somalia dust-laden macrophages in lungs and/or bronchial lymph nodes were discovered in 94 of 134 animals. In 44 cases the dust-laden macrophages occurred in a number of small or large aggregates. There was a significant positive correlation between

Studies on the hazardous effects and the maximum allowable concentration of pyrophyllite dust.

Numai utilizatorii înregistrați pot traduce articole

Pyrophyllite (H2Al2Si4O22) dust (P-dust) is a mixture of silica (10-40%), different proportions of a luminium oxide (Al2O3), and various metal compounds. People with occupations known to be associated with exposure to P-dust include miners, other industrial workers and persons engaged in artistic

Tumorigenicity of fine man-made fibers after intratracheal administrations to hamsters.

Numai utilizatorii înregistrați pot traduce articole

Six types of man-made fibers were administered intratracheally (2.0 mg/animal each a week, for 5 weeks; total 10 mg/animal) to female Syrian hamsters that were observed histologically for 2 years after administration. The fibers were rock wool [average diameter (D) = 6.1 microns, average length (L)

Atomic absorption spectrophotometric and X-ray studies of respirable dusts in Indian coal mines.

Numai utilizatorii înregistrați pot traduce articole

Quantitative determination of 10 minor and 8 trace elements in respirable coal dust by atomic absorption spectrophotometry is described herein. The coal dust samples were collected in the mine atmosphere during drilling in coal seams. A "Hexhlet" apparatus specially designed and fitted with a

The Nalp3 inflammasome is essential for the development of silicosis.

Numai utilizatorii înregistrați pot traduce articole

Inhalation of crystalline silica and asbestos is known to cause the progressive pulmonary fibrotic disorders silicosis and asbestosis, respectively. Although alveolar macrophages are believed to initiate these inflammatory responses, the mechanism by which this occurs has been unclear. Here we show
