OBJECTIVES The objective of this study is to investigate the distribution patterns and exposure concentrations of bioaerosols in industries suspected to have high levels of bioaerosol exposure. METHODS We selected 11 plants including 3 livestock feed plants (LF industry), 3 metal working fluids handling plants (MWFs industry), and 5 sawmills and measured total airborne bacteria, fungi, endoto...

Objective: To analyze the role of plasma cytokines and endotoxin in patients with acute aortic dissection (AAD) in concluding prognostic effect. Material and methods: A total of 85 patients with acute aortic dissection were admitted in 2nd affiliated hospital of Zhengzhou university from January 2009 to November 2015. Patients were divided into death group and survival group. At the time of adm...

The endotoxins of gram-negative bacteria in minute amounts elicit an array of characteristic physiological alterations in mammals including such diverse phenomena as production of fever (1, 3), stimulation of resistance to infection (12, 21, 29), and protection against radiation injury (26). Higher dosage induces a state of stress, acute shock, or eventual death. In tumorbearing animals, extens...

"Blockade" of the RES by thorotrast so lowered the tolerance of hemorrhagic shock in rabbits and dogs that a reversible degree of hemorrhagic shock became irreversible. This was true not only in normal rabbits, but in rabbits made resistant to hemorrhagic shock by producing resistance to endotoxins. Rabbits which had been pretreated with thorotrast and then subjected to hemorrhagic shock displa...

The aim of the study was to assess the levels of inhalable dust, endotoxins and (1-3)-β-d-glucans as agents harmful to the respiratory tract of workers of municipal waste sorting plants and interaction between these agents based on the measurements taken in two plants with different processing capacities. The study was conducted in summer season in two waste sorting plants (WSPs) differing in p...

The aim of this cross-sectional study was to investigate the occurrence bacteremia in severe mastitis cases dairy cows. Milk and corresponding blood samples 77 were bacteriologically examined. All (milk blood) incubated aerobically anaerobically also role obligate anaerobic microorganisms addition aerobic mastitis. Bacteremia occurred if identical bacterial strains isolated from milk same case....
