Cadmium is a common contaminant in sawdust and other materials used in laboratory animal bedding. This study was conducted to assess the irritancy of a soluble cadmium compound to the skin and percutaneous absorption of the cadmium ion. Cadmium chloride solution was administered to the shaved skin of the dorsum of rats and mice daily for 10 days at(More)
Beriplex, a prothrombin complex concentrate (PCC), was administered to 42 patients requiring immediate reversal of their oral anticoagulant therapy. The dose administered was determined using the pretreatment International Normalized Ratio (INR). Blood samples were obtained before treatment and at 20, 60 and 120 min after treatment. The following(More)
We carried out metal artefact-reduction MRI, three-dimensional CT measurement of the position of the component and inductively-coupled plasma mass spectrometry analysis of cobalt and chromium levels in whole blood on 26 patients with unexplained pain following metal-on-metal resurfacing arthroplasty. MRI showed periprosthetic lesions around 16 hips, with 14(More)
Metalloenzymes have an important role in repair and regenerative processes in skin wounds. Demands for different enzymes vary according to the phase in the healing cascade and constituent events. Sequential changes in the concentrations of calcium, copper, magnesium and zinc were studied in the incisional wound model in the rat over a 10 d period. Copper(More)
Incisional wounds 15 mm long were induced surgically in the back skin of young adult Wistar rats. They were sutured and used as an experimental model in the therapeutic evaluation of daily applications of 0.5 mL of silver nitrate (SN) at 0.01, 0.1 or 1.0% w/v aqueous solution, or 0.5 g silver sulphadiazine (SSD) over a 10-day period. Control wounds received(More)
The development of a sensitive enzyme-linked immunosorbent assay (ELISA) for human metallothionein-1 is reported. Metallothionein was purified from postmortem human liver and used to raise high-titer antibodies in rabbits. The assay was specific for human metallothionein-1 (MT-1), and there was no significant cross-reaction with human metallothionein-2. The(More)
We have studied four patients suffering from acquired von Willebrand's disease. All patients had a severe bleeding diathesis with recurrent life-threatening haemorrhages. Three of the patients had a monoclonal gammopathy and one of these developed multiple myeloma. In three patients tested, a plasma inhibitor to ristocetin cofactor activity was detected. In(More)
BACKGROUND Bariatric surgery is widely performed to improve obesity-related disorders, but can lead to nutrient deficiencies. In this study we examined serum trace element concentrations before and after bariatric surgery. METHODS We obtained serum trace element concentrations by inductively coupled plasma-mass spectrometry (ICP-MS) method in 437 patients(More)
Blood lead and plasma aluminium concentrations have been measured in patients with end-stage chronic renal failure treated by haemodialysis (HD) or by continuous ambulatory peritoneal dialysis (CAPD) and in a control group of non-dialysed patients with chronic renal failure (CRF). Data on a group of subjects with normal renal function is included for(More)
BACKGROUND Calprotectin (complex of S100A8 and S100A9) is the major calcium and zinc-binding protein of phagocytes. We report a new syndrome with recurrent infections, inflammation, and hyperzincaemia associated with excessively high plasma concentrations of calprotectin. METHODS We measured calprotectin in plasma and protein fractions by ELISA assay and(More)
