Metabolismes of methylmercury sulfate and methylmercury iodide in animals
Cats fed (CH3Hg)2SO4 developed the same findings as spontaneously affected cats fed the poisonous seafood from Minamata Bay. The organomercury compound in raw organs such as the liver, the kidney, and the bone marrow of the above animals did not transfer to chloroform, but it transferred easily to BAL.

Behavioral teratology of methylmercury.
Behavioral effects of experimental perinatal methylmercury exposure are reviewed. Studies were summarized by classification based on examined behaviors and functions as follows; Development of reflexive behaviors, Swimming ability, Spontaneous activity, Open-field behavior, Maze learning, Avoidance learning, Operant learning, Susceptibility to induced ...

Methylmercury-Cholinesterase Interactions in Rats
The interaction of methylmercury hydroxide (MMH) and cholinesterases was studied in male and female rats. MMH administered subcutaneously in doses of 10 mg/kg for 2 days reduced the level of plasma cholinesterase (ButChE) by 68% in females and 47% in males while brain acetylcholinesterase (AChE) was unaffected.

Interaction between Selenium and Methylmercury
The available data on the influence of selenium on the toxicity of methylmercury and of methylmercury on selenium as a nutrient and toxic agent are reviewed. Selenium as selenite has a relative protective effect on acute and subacute toxicity of methylmercury in the rat and the quail. The protective mechanism is far from clear.

Methylmercury toxic mechanism related to protein degradation and chemokine transcription
Methylmercury is an environmental pollutant that causes neurotoxicity. Recent studies have reported that the ubiquitin-proteasome system is involved in defense against methylmercury toxicity through the degradation of proteins synthesizing the pyruvate ...

We recently found that tumor necrosis factor-α (TNF-α) may be involved in neuronal cell death induced by methylmercury in the mouse brain. Here, we examined the cells involved in the induction of TNF-α expression by methylmercury in the mouse brain by in

We evaluated the potential neuroprotective effect of 1-100 µM of four organoselenium compounds: diphenyl diselenide, 3’3-ditri-fluoromethyldiphenyl diselenide, p-methoxy-diphenyl diselenide, and p-chloro-diphenyl diselenide, against methylmercury ...

Glia and Methylmercury Neurotoxicity [PDF]
Methylmercury (MeHg) is a global environmental pollutant with significant adverse effects on human health. As the major target of MeHg, the central nervous system (CNS) exhibits the most recognizable poisoning symptoms. The role of the two major nonneuronal cell types, astrocytes and microglia, in response to MeHg exposure was recently compared.

Indigenous Arctic Canadians have a higher prevalence of gastric neoplasms relative to North Americans of European ancestry. We investigated the hypothesis that low-dose methylmercury exposure from eating fish/whale increases the risk of gastric cancer in
