The toxic effects of beryllium salts have been studied on the reproductive organs of cyclic adult female albino rats; simultaneously an attempt has been made to overcome these effects by using an Ayurvedic remedy Liv.52 (The Himalaya Drug Co., Bombay). Liv.52-primed rats (1 ml/rat/d for 15 days) were exposed to beryllium nitrate intravenously and were sacrificed at different time intervals. At ...

The electrical conductivity of beryllium at radio frequency (800 MHz) and liquid nitrogen temperature were investigated and measured. This summary addresses a collection of beryllium properties in the literature, an analysis of the anomalous skin effect, the test model, the experimental setup and improvements, MAFIA simulations, the measurement results and data analyses. The final results show ...

OBJECTIVES Beryllium sensitisation (BeS) and chronic beryllium disease (CBD) are caused by exposure to beryllium with susceptibility affected by at least one well-studied genetic host factor, a glutamic acid residue at position 69 (E69) of the HLA-DPβ chain (DPβE69). However, the nature of the relationship between exposure and carriage of the DPβE69 genotype has not been well studied. The goal ...

CD4(+) T cells play a key role in granulomatous inflammation in the lung of patients with chronic beryllium disease. The goal of this study was to characterize activation pathways of beryllium-responsive bronchoalveolar lavage (BAL) CD4(+) T cells from chronic beryllium disease patients to identify possible therapeutic interventional strategies. Our results demonstrate that in the presence of A...

Following paper presents current studies on beryllium block poisoning based on beryllium moderated research reactor MARIA. Description of the problem was given along with calculation and measurement methodology. At the moment the experimental campaign is still under development.

BACKGROUND The relevance of beryllium sensitization testing for occupational health practice and prevention is unclear. AIMS To analyse the natural course of beryllium sensitization and clarify the prognosis following cessation of exposure among sensitized workers. METHODS An electronic literature search was conducted in PubMed, Embase, Toxline and Cochrane databases supplemented by a manua...

The blood beryllium lymphocyte proliferation test (BeLPT) is an in vitro measure of the beryllium antigen-specific cell-mediated immune response. This response to beryllium is now understood to play a central role in the immunopathogenesis of chronic beryllium disease (CBD). Although there remain some unresolved methodologic issues with testing, the blood BeLPT has already undergone sufficient ...
