Quantitative morphological-stereological-analysis of at least two, the mercuric chloride- and the maleate-induced experimental models of toxic acute renal failure, show a very early substantial loss of ATP-generating mitochondrial inner membrane surface as well as substantial decrease in those functions protecting cells against oxidative or auto-oxidative processes, i.e. glutathione content, activities of the free-radical-scavenging systems superoxide dismutase, glutathione peroxidase and glutathione reductase and catalase.

This study examined the effects of inorganic mercury (mercuric chloride - HgCl2) exposure exclusively through maternal milk on biochemical parameters related to oxidative stress (glutathione and thiobarbituric acid reactive substances levels, glutathione peroxidase and glutathione reductase activities) in the cerebellum of weanling mice.

Present study investigated the protective role of melatonin (MLT, 5mg/kg body wt., ip) against the long term effects of mercuric chloride (MC; 2 and 4 mg/kg body wt., po) in the thyroid gland of the rats through certain antioxidative indices like superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione (GSH), catalase (CAT) and lipid peroxidation (LPO), other biochemical parameters such as succinate dehydrogenase (SDH), adenosine triphosphatase (ATPase), acid phosphatase (ACPase) and alkaline phosphatase (ALPase) were also measured.

The effects of mercuric chloride (Hg) on lipid peroxidation (LPO), glutathione reductase (GR), glutathione peroxidase (GPx), superoxide dismutase (SOD) and glutathione (GSH) levels in different organs of mice (CD-1) were evaluated.

We analyzed the effects of mercuric chloride (HgCl (2)) 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) and glutaredoxin (Grx).

The effect of mercuric chloride (HgCl2) on the activities of catalase, superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR) and its effect on glutathione (GSH) content were evaluated in different organs (liver, kidneys, and brain) of mice after administration at 0, 0.25, 0.5 and 1.0 mg/kg/day for 14 days.

Sperm samples were dispersed in RPS medium (pH 6.9) and incubated with mercury in the form of mercuric chloride (MC) at three different concentrations (1 microM, 10 microM, 100 microM), melatonin (MLT) at a concentration (100 microM) and mercuric chloride+melatonin (100 microM each) for 3h at 32 degrees C.
An aliquot of sperm sample was homogenised, centrifuged and used for the assay of superoxide dismutase, glutathione peroxidase, glutathione reductase, TBARS assay to detect lipid peroxidation and hydrogen peroxide generation assay.

Other enzyme activities related to the glutathione redox cycle, such as glutathione reductase (GR) and glucose-6-phosphate dehydrogenase (G6PDH), also increased progressively.

Increases in superoxide dismutase, catalase, glutathione peroxidase (GPx), glutathione S-transferase (GST) and glutathione reductase (GR) were observed in all tissues after HgCl (2) exposure, except for white muscle GR activity and hepatic GPx.

2554540 Hellstrom-Lindahl E, Oskarsson A: Increased availability of mercury in rat hepatocytes by complex formation with diethyldithiocarbamate. Toxicol Lett. 1989 Oct;49(1):87-98.

The availability of different chemical forms of mercury (Hg) was studied in primary cultures of rat hepatocytes incubated with mercuric acetate (HgAc), mercuric diethyldithiocarbamate (Hg (DTC) 2) or methyl mercuric chloride (MeHgCl), labelled with 203Hg.
On the other hand, glutathione reductase was inhibited to a higher degree by HgAc than by Hg (DTC) 2, indicating that Hg (DTC) 2 remains at least temporarily in the complexed form and that the enzyme is less susceptible to Hg in this form.
