Zinc toxicity has been linked to cellular glutathione: A decrease in glutathione is followed by an increase in zinc-mediated toxicity. The question arises whether an increase in glutathione synthesis might decrease zinc-mediated cytotoxicity. We incubated five cell lines (hepatoma and lung-derived) with zinc chloride and 2 mmol/l N-acetyl-L-cysteine (NAC) to support glutathione synthesis.

Aims: Vanadium is currently undergoing clinical trials as an oral drug in patients with noninsulin-dependent diabetes mellitus. Furthermore, vanadium occurs in elevated concentrations in the blood of patients receiving intravenous albumin solutions containing large amounts of the metal ion as an impurity. The present study was performed to examine the pharmacokinetics of vanadium in humans following a single intravenous (i.

The binding of vanadate (V) to human serum albumin (HSA) in infusion solutions, to human fresh frozen plasma (FFP), and to human transferrin (TF) was investigated over a wide concentration range. Free V concentrations were obtained by ultrafiltration. Total and free V concentrations were determined using electrothermal atomic absorption spectrometry (ETAAS).
