on triclosan, a antibacterial in various products such as shampoos, toothpastes, deodorants, detergents, and even in some fabrics and shoes, would be toxic to nervous system and neuronsaccording to Chilean scientists.
The study, whose first results were published in the magazine Boundaries in Molecular Neurology, developed by researchers from the Millennium Neuroscience Biomedical Institute (BNI), belonging to the Medical Faculty of the University of Chile. The findings of the team led by Cell Biology and Neuroscience physician Genaro Barientos add to the findings made around the world in which damage from toxicity Hepatic, intestinal and skeletal muscles and heart are due to triclosan.
In other countries, such as USA and Australiaconcentrations of this chemical are also found in the tissues of animals and humans. "Given the existing evidence, we think it is very important to continue to explore this area and the impact of this chemical because the use of products with antimicrobial"Barientos commented.
"There is a consensus that it is important to eliminate the bacterial burden as much as possible"warned that many people" can harm their brains "by using triclosan used in the industry for their antibacterial and preserving capacities.
The researchers conducted an experimental project to study behavior and neurological effects in mouse and neuronal patterns in culture. – The most important thing we find is that triclosan influences the formation and processing of memory– explained Barrientos, also a researcher at the Center for Exercise, Metabolism and Cancer Research, CEMC. "To our surprise the effect is quite large. We have conducted neuronal culture studies in vitro and also exposed to animals by intracerebral injection at very low concentrations of this compound ", in detail.
Triclosan has changed the functioning of neurons, but "the most interesting result in mice: those who have been exposed to poison, no matter," describes the work.
Tests have shown, according to scientists from the neighboring country, that the compound seriously affects memory and spatial meaning, and "worse, high toxic concentrations are not required to produce the damage."
The recommendations of the authors of the study
Triclosan is commonly used in products that are sold with added value,antimicrobial properties"The signal is particularly sensitive to children and the elderly, as the composition may alter the development and triggering diseases neurodegenerative, "The chemical component has been on the market for a long time, and although its presence is detailed on every product, we think the best option is to eliminate it," they warn.
On this basis, the next step of the researchers is to analyze triclosan concentrations in the human brain, according to a study transcendental,
