Rare-earth element " Also also evil "
Does rare-earth element influence the health? The young scientific research personnel of health and epidemic prevention station of Shenzhen go through 5 to study, this a few days ago correctly Have issued one's own achievement in question. Researchers think, rare-earth element can be absorbed by the plant, the animal has eaten and contained the rare earth The plant of the element, rare-earth element will be accumulated in the body, and produce through the nucleotide signal system of the ring Biological effect. If rare-earth element is entering the human body constantly and accumulating through the food chain, its biological result Should may show as toxicity acts on, bring the harmful effects to health. There are 17 kinds of rare-earth elements, because some elements among them have facilitation to grow to the animals and plants, used extensively agriculture, animal husbandry, feeding,etc., it influences the health, become the focal point paid close attention to and studied both at home and abroad in recent years. The intersection of Shenzhen and health and epidemic prevention station explain run a country doctor, the intersection of village and the intersection of will and male Professor,et al. launch 5 years ago ' The studying of influence that cerium surrounds the signal system of nucleotide to the liver>>, has obtained country and Guangdong Province naturally Subsidy of the scientific fund. The reason why the one that choose in rare-earth element " Cerium " Carry on biological effect research, it is because of " cerium " Used in the intersection of rare earth and a little fat, the intersection of feed and production of additive extensively already, the most representative. Discover, liver and hepatocyte in the organism are that the rare earth ion give play to the important target organ of the biological effect With target cells, the route of its function is: Rare-earth element acts on the surface of cell, surround the nucleotide to the liver The signal system produced the constant stimulus. At the time of the low density, it stimulates function to be positive, can promote The animal grows. At the time of the high density, will be shown as toxicity because of excessively stimulating. It is introduced, the angle conducted from the signal for the first time in this research, the system has announced cerium to the liver ring The influence of the signal system of nucleotide, has proposed rare-earth element " cerium " clearly Physiology and it is toxicological mechanism,theoretical foundation which offer for guiding rare-earth element and utilizing, making the relevant sanitary standard certain.
