Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...

Background and Aims: Mercury, with its oxidative activity, causes damage to the antioxidant enzymes thus resulting in physiological disorders. Sodium selenide is an antioxidant that protects antioxidant enzymes. The aim of this study was to investigate the protective effect of sodium selenide on renal toxicity induced by mercuric chloride in rats. Materials and Methods: Animals were divided in...

One of the important abiotic stresses that negatively affect cereals such as wheat is heavy metals. Soil pollution with heavy metals has become one of the major environmental concerns resulting from the industrial development and use of fertilizers containing heavy metals. One way to counteract the negative effects of heavy metals in plants which produce reactive oxygen species is the activatio...

Renal cell lines are frequently used models in toxicology. The aim of the experiments described here was to investigate the suitability of two of those renal cell lines, namely NRK-52E and LLC-PK1, as models for mid to late stage apoptosis under standard cell culture conditions; the latter means that testing was performed in the presence of serum in the culture media. Seven known inducers of ap...

Reactive oxygen species are implicated as mediators of tissue damage in ischemic and toxic acute renal failure. Whereas many agents can inhibit renal ischemic injury, only hepatocyte growth factor, melatonin, N-acetylcysteine, and DMSO inhibit injury after mercuric chloride administration. Although it has been suggested that DMSO may chelate the mercuric ion, more recent studies suggest that it...

background: exposure to any xenobiotic can disturb the metabolic activities of particular organs. hence present study is designed to find changes in hepatic biochemistry, histochemistry and histopathology besides serum enzyme levels after acute and sub-acute treatment with mercuric chloride, a heavy metallic compound, in albino rat (rattus norvegicus). materials & methods: thirty albino rats we...

a b s t r a c tintroduction: because of more exposure to mercury compounds, the prenatal and postnatal neurotoxic effects of mercury compounds have gained more attention in last decade. the aim of this study was to investigate the effects of mercuric chloride intoxication on spinal cord development during prenatal period. methods: 36 adult sprague-dawley rats after observing vaginal mating plaq...

Experiments were undertaken to test how aquaporins (AQPs) facilitate the uptake of water by roots of Pisum sativum. Changes in PsPIP2-1 gene expression and root hydraulic conductivity (Lpr) were measured in response to the time of day as well as treatment of the roots with a compound that reduced Lpr [i.e. mercuric chloride (HgCl2)] and one that was intended to increase Lpr [abscisic acid (ABA)...

Hypotheses that dissolved organic carbon (DOC) and electrochemical charge affect the rate of methylmercury [CH3Hg(I)] synthesis by modulating the availability of ionic mercury [Hg(II)] to bacteria were tested by using a mer-lux bioindicator (O. Selifonova, R. Burlage, and T. Barkay, Appl. Environ. Microbiol. 59:3083-3090, 1993). A decline in Hg(II)-dependent light production was observed in the...

Autoantibodies to nucleolar components are a common serological feature of patients suffering from scleroderma, a collagen vascular autoimmune disease. While animal models, which spontaneously develop abundant anti-nucleolar antibodies, have not yet been described, high titers of such antibodies may be induced by treating susceptible strains of mice with mercuric chloride. We have identified th...
