Effect of Methylmercury on Depression like Behavior in Rats: a Study Mitigated by Exogenous Vitamins
Depression is a heterogenous, multifaceted disorder with symptoms manifested at the psychological, behavioral and physiological level. Therefore, present study was designed as a model to analyze the long lasting effects of methylmercury chloride in male rats with a focus on depression like behavior. Male albino rats of Wistar strain were exposed orally to a dose of 2 mg/kg of methylmercury chlo...
background: mercury is widespread and persistent in the environment. one organic form of mercury, methylmercury (mehg), can accumulate in the food chain in aquatic ecosystems and lead to high concentrations of mehg in fish, which, when consumed by humans, can result in an increased risk of adverse effects. currently, the joint fao/who expert committee on food additives (jecfa) has established p...

In this study, concentration of 17 elements, including As, Ba, Cd, Co, Cu, Hg, Mn, Ni, Pb, Zn, Ca,Fe, Mg, Na, P, S, Si, as well as methylmercury in 31 surface sediments were assessed. The sampling stations were Gulf of Golestan, Miankale Island, Babolsar, Nowshahr and Anzali, which represented the most important harbors in the Golestan, Mazandaran and Gilan provinces in the southern parts of th...
Methylmercury is a hazardous substance that is of interest with regard to environmental health, as inorganic mercury circulating in the general environment is dissolved into freshwater and seawater, condensed through the food chain, ingested by humans, and consequently affects human health. Recently, there has been much interest and discussion regarding the toxicity of methylmercury, the correl...
Methylmercury causes serious damage to the central nervous system, but the molecular mechanisms of methylmercury toxicity are only marginally understood. In this study, we used a gene-deletion mutant library of budding yeast to conduct genome-wide screening for gene knockouts affecting the sensitivity of methylmercury toxicity. We successfully identified 31 genes whose deletions confer resistan...
Methylmercury is well known for causing adverse health effects in the brain and nervous system. Estimating the elimination constant derived from the biological half-life of methylmercury in the blood or hair is an important part of calculating guidelines for methylmercury intake. Thus, this study was conducted to estimate the biological half-life of methylmercury in Korean adults. We used a one...
A simplified mass screening method for methylmercury exposure was developed using methylmercury-volatilizing bacteria from Minamata Bay. Some bacteria can transform methylmercury into mercury vapor. Most mercury in the hair is methylmercury, which is readily extracted with HCl solution. Black spots are formed on X-ray film due to the reduction of Ag(+) emulsion with mercury vapor produced by me...
A detailed understanding of the formation of the potent neurotoxic methylmercury is needed to explain the large observed variability in methylmercury levels in aquatic systems. While it is known that organic matter interacts strongly with mercury, the role of organic matter composition in the formation of methylmercury in aquatic systems remains poorly understood. Here we show that phytoplankto...
