1. The use of two-dimensional thin-layer chromatography is described that allows the rapid and simultaneous determination of phospholipid classes and their constituent plasmalogens. 2. The method is based on the specific hydrolysis of plasmalogens to (2-acyl) lysophospholipid in the presence of a mercuric chloride spray reagent. 3. The proportion of mercuric chloride-labile phospholipid present...

An immunoassay that detects mercuric ions in water at concentrations of 0.5 ppb and above is described. The assay utilizes a monoclonal antibody that binds specifically to mercuric ions immobilized in wells of microtiter plates. Within the range of 0.5-10 ppb mercury, the absorbance in the enzyme-linked immunosorbent assay (ELISA) is linear to the log of the mercuric ion concentration. The quan...

In the Brown Norway (BN) rat, mercuric chloride (HgCl(2)) induces a T(h)2-dominated autoimmune syndrome which includes an early phase of mast cell-dependent vasculitis. We have shown in vitro that oxidative stress up-regulates IL-4 in mast cells and predisposes to degranulation. The aim of this study was to determine whether administration of antioxidants inhibits HgCl(2)-induced early vasculit...

forty bacteria species commonly found in soil, sediments, and sewage effluent were exposed for acclimation to inorganic and organic mercury compounds using sterilized sediments as the culture medium. screening tests for the ability of microorganisms to methylate inorganic mercury were made on all 40 species after acclimation to 13.5 mg/i mercuric chloride. additional screening tests for demethy...

The effect of selenite administered at various time intervals after mercury treatment on the toxicity and renal content of mercuric mercury in mice was studied. A marked protective effect of selenite on growth depression and renal lesions caused by mercuric chloride was observed in mice receiving mercury and selenite simultaneously. However, growth depression was not protected by post administr...
