Extractions: The endocrine system is a complex network of glands and hormones that regulates many of the body's functions, including growth, development and maturation, as well as the way various organs operate. The endocrine glands including the pituitary, thyroid, adrenal, thymus, pancreas, ovaries, and testes release carefully-measured amounts of hormones into the bloodstream that act as natural chemical messengers, traveling to different parts of the body in order to control and adjust many life functions. An endocrine disruptor is a synthetic chemical that when absorbed into the body either mimics or blocks hormones and disrupts the body's normal functions. This disruption can happen through altering normal hormone levels, halting or stimulating the production of hormones, or changing the way hormones travel through the body, thus affecting the functions that these hormones control. Chemicals that are known human endocrine disruptors include diethylstilbesterol (the drug DES), dioxin, PCBs, DDT, and some other pesticides. Many chemicals, particularly pesticides and plasticizers, are suspected endocrine disruptors based on limited animal studies.
Endocrine Disruptor - Wikipedia, The Free Encyclopedia endocrine disruptors are exogenous substances that act like hormones in the endocrine system and disrupt the physiologic function of endogenous hormones. http://en.wikipedia.org/wiki/Endocrine_disruptor
Extractions: Jump to: navigation search Endocrine disruptors are exogenous substances that act like hormones in the endocrine system and disrupt the physiologic function of endogenous hormones . Studies have linked endocrine disruptors to adverse biological effects in animals, giving rise to concerns that low-level exposure might cause similar effects in human beings. Since the publication of Rachel Carsonâs Silent Spring (Carson, 1962), there has been concern that chemicals in the environment might exert profound and deleterious effects on wildlife populations, and that human health is inextricably linked to the health of the environment. Although researchers had studied the endocrine effects of chemicals in the past, the term endocrine disruptor was coined in 1991 at a conference at the Wingspread Conference Center in Racine, Wisconsin . This conference was chaired by Theo Colburn , then with the World Wildlife Fund and the W. Alton Jones Foundation. The term was introduced into the scientific literature with her

Questions About Endocrine Disruptors By EPAs working definition, endocrine disruptors interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones http://extoxnet.orst.edu/faqs/pesticide/endocrine.htm
Extractions: Questions about Endocrine Disruptors Here are some of the most frequently asked questions about the endocrine system and endocrine disruptors: The endocrine system is composed of ductless glands that secret hormones into the blood stream to act at distant sites. Together with the nervous system, the endocrine system is responsible for the integration of many different processes which allow complicated organisms to function as a unit (maintain homeostasis). What does the endocrine system look like? Hormones can be proteins, polypeptides, amino acids, or steroids. The most well known hormones are the sex steroids estrogen, produced in the ovaries, and testosterone, produced in the testes. Estrogen and testosterone are also produced in the adrenal glands of both sexes. Other hormones include thyroxin, produced in the thyroid, and insulin, produced in the pancreas. The pituitary and hypothalamus in the brain release a variety of hormones that affect other organs, including the sex glands. How do hormones work?

While this all serves a valuable purpose in our bodies, it also makes endocrine disruption more potentially hazardous. An endocrine disruptor is a synthetic compound that mimics a natural hormone when it is absorbed by the body. It can turn on, turn off, or change normal signals. It can have the effect of altering normal hormone levels, triggering excessive action, or completely blocking a natural response. Any other bodily function controlled by hormones can also be affected. In humans, the natural level of circulating hormones needed to orchestrate bodily functions is relatively low. Synthetic endocrine disruptors are now being found in living tissue at dramatically higher concentrations than natural hormones. A CDC report from July 2005 found that the bodies of Americans of all ages contain an average of 148 synthetic chemicals.

Extractions: People must stop thinking of bodily systems as individual entities that are neatly divided, and think of the whole body as a system that is infinitely interconnected within itself, as well as to all matter on earth living or otherwise. As each infinitely small part or function is disabled, we lose a little more of the viability of our species and that of all others. Just because an effect is unseen by human observers science means little in the long run. I am quite certain that something big is happening to our health. Of course we all know someone or have a relative who has had cancer, that goes without saying. But today, it's becoming just as prevalent that we all know someone who has trouble with conceiving a child. And then when they are successful after partaking in some form of medical intervention, the children have problems. Modern medicine is not capable of dealing with the problems that have been created by our flagrant misuse of science. There will never be a cure for cancer by adding more layers of scientific mumbo-jumbo.

The endocrine system is comprised of a number of glands in the body that do not have ducts and other similar structures. Glands in the endocrine system include the ovaries; the testes; the thyroid, parathyroid, adrenal, and pituitary glands; the pineal body; the pancreas; as well as cells of the gastrointestinal tract, and the placenta. What distinguishes endocrine glands from other glands is that endocrine glands secrete certain chemical called hormones and other glands produce other chemicals or fluids; for example, lacrimal glands secrete tears, salivary glands produce saliva, and sweat glands produce sweat. Hormones (so-called "chemical messengers") produced by endocrine glands enter the capillaries (and lymph vessels) of the blood circulatory system. They travel through the bloodstream to specific "receptors" in target organs or systems where they can trigger their biological effects.

His work suggests that endocrine disruptors such as bisphenol A, or BPA, may affect developing offspring in the earliest days of pregnancy. In an experiment published in July in Proceedings of the National Academy of Sciences , Jirtle found that feeding BPA to female mice changed the color of their babies' coats. BPA caused more than cosmetic changes. In this breed, brown mice grow up with healthy weights, while those with yellow coats grow up to be obese, with a higher susceptibility to cancer and diabetes. In Jirtle's experiment, mothers fed BPA before, during and after pregnancy had twice as many yellow babies

Extractions: The endocrine system in humans and other animals has an important job. It produces the hormones that regulate the body's various processes, such as metabolism and reproduction, which are vital to the chemistry of life. One example of a hormone is insulin, which breaks down sugar. Another is adrenalin, which pumps us up so we can deal with stress or danger. Estrogens are hormones that impart female characteristics and androgens impart male characteristics. "Gender benders" Endocrine-active chemicals (sometimes called "endocrine disruptors") received wide publicity in 1996 with the publication of "Our Stolen Future", which dramatized the impact of accidental chemical spills and other isolated incidents on wildlife - and hypothesized that humans could also be harmed. What gave the book an added fear factor was its emphasis on potential effects on sexual development and reproduction. The book speculated that even extraordinarily low levels of some chemicals, delivered at just the wrong time, may currently be having calamitous consequences on human sexual structure, function, behavior and even identity. Some have coined a catchy phrase for such chemicals - "gender benders." A few chemicals and some natural substances (for example, soybeans are weakly estrogenic), can impact the endocrine system to some degree. However, there is no scientific agreement on how to define or test for an endocrine-active effect. Nor is there a consensus whether human reproductive capacity in the general population has changed in recent years, let alone what may be responsible. Nevertheless, lists of alleged human endocrine disruptors continue to circulate. Given the lack of consensus on the definition and consequence of an endocrine-active effect, the relevance of these lists of alleged endocrine disruptors is in serious doubt.

Extractions: About NRP50 The presence of hormonally active chemicals ("endocrine disruptors") in the biosphere has become a worldwide environmental concern. In 1999, a report released by the Swiss Agency for the Environment, Forests and Landscape (BUWAL) concluded that such chemicals have already left their mark on the Swiss landscape and implicated them as a general cause of population changes in wildlife. Some of the chemicals involved, for example polychlorinated biphenyls (PCBs) and dibenzo-p-dioxins (dioxins), have received wide media attention because of their negative health impact on humans. The potential contribution of endocrine disruptors to the increased incidence of a number of diseases and developmental disorders in humans and animals is alarming, but the establishment of solid cause-effect relationships requires further scientific investigation. In Switzerland, the necessity for a coordinated transdisciplinary approach to the environmental and public health problems caused by endocrine disruptors is now widely recognized. The Federal Council has implemented a National Research Programme (NRP) on "Endocrine Disruptors" which aims to develop scientific strategies to assess the risks and hazards that arise when endocrine disruptors are processed through ecosystems and cause human and animal exposure. Major objectives to be addressed are: What is the magnitude of exposure of humans, domestic animals, wildlife and the environment in Switzerland?
