Japanese quail (Coturnix c. japonica) were fed 0, 2, 4, 8, 16, and 32 p.p.m. Hg as mercuric chloride (HgCl2) from the time of hatching up to the age of 1 year. None of the birds manifested any gross signs of mercury poisioning. Food consumption, growth rate, and weight maintenance were unaffected. Initial oviposition tended to occur at a younger age as dietary mercuric chloride increased, e.g.,...

BACKGROUND The present study was undertaken to study the effect of mercuric chloride (HgCl2) on the collagen metabolism in rats and the protective effect of 2, 3-dimercapto-1-propane sulfonic acid (DMPS) in HgCl2-treated rats. MATERIAL/METHODS The experimental groups studied were (i) a control group (ii) rats injected with a single intraperitoneal (ip) dose of 2 mg of HgCl2/kg body weight (Hg...

To assess effects of epidermal growth factor (EGF) and pegylated granulocyte colony-stimulating factor (P-GCSF; pegfilgrastim) administration on the cellular origin of renal tubular epithelium regenerating after acute kidney injury initiated by mercuric chloride (HgCl2 ). Female mice were irradiated and male whole bone marrow (BM) was transplanted into them. Six weeks later recipient mice were ...

Although fish in natural populations may carry high body burdens of both organic and inorganic mercury, the effects of this divalent metal on such lower vertebrates is poorly understood. In this report, inorganic mercury in the form of mercuric chloride (HgCl2) is shown to produce both high-dose inhibition and low-dose activation of leukocytes in a marine teleost fish, Sciaenops ocellatus. Conc...

Mercury toxicity mediated by different forms of mercury is a major health problem, however, the molecular mechanisms underlying toxicity remains elusive. We analyzed effects of mercuric chloride (HgCl2) and monomethylmercury (MeHg) on the proteins of the mammalian thioredoxin system, thioredoxin reductase (TrxR) and thioredoxin (Trx), and of the glutaredoxin system, glutathione reductase (GR) a...

the objectives of this work was to examine the toxicological effect and molecular changes caused by a heavy metal pollutant mercuric chloride (hgcl2), in fresh water snakehead channa punctatus, locally known as taki fish in bangladesh. when fishes were exposed to hgcl2, it induced death of the fishes in a concentration-dependent manner. 1 mm, the highest concentration tested in this study, was ...

In genetically susceptible H-2s mice, subtoxic doses of mercuric chloride (HgCl2) induce a complex autoimmune syndrome characterized by the production of anti-nucleolar IgG Abs, lymphoproliferation, increased serum levels of IgG1 and IgE Abs, and renal Ig deposits. Mercury-induced autoimmunity in H-2s mice provides a useful model for chemically related autoimmunity in humans. The increase in se...

The present investigation has been undertaken to evaluate role of Wheat grass extract in modifying mercury-induced biochemical alterations in albino rats. Mercuric chloride 5 mg/kg body weight i.p. was given on 11, 13 & 15th day of the experiment. Wheat grass extract (400 mg/kg) and Quercetin (10 mg/kg) were administered 10 days before mercuric chloride administration and continued up to 30 day...

Mercurials may induce immune manifestations in susceptible individuals. Mercuric chloride (HgCl2) induced autoimmunity in the Brown Norway (BN) strain but an immuno-suppression in the Lewis strain with, however, autoreactive anti-class II T cells present in both strains. In the present study we looked at modifications of cytokine production by PCR and cytofluorometric analyses in normal BN and ...
