It is taken by mouth. Maximal effects may take up to three weeks to occur. Side effects may occur from excessive doses. This may include weight loss, fever, headache, anxiety, trouble sleeping, arrythmias, and heart failure. Other side effects may include allergic reactions. Use in pregnancy and breastfeeding is generally safe. Regular blood tests are recommended to verify the appropriateness of the dose. They contain a mixture of thyroxine (T4) and triiodothyronine (T3). Desiccated thyroid has been used since the late 1800s. It is usually made from pigs, sheep, or cows. It is available as a generic medication. In 2020, it was the 117th most commonly prescribed medication in the United States, with more than 5million prescriptions.

They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine. A deficiency of iodine leads to decreased production of T3 and T4, enlarges the thyroid tissue and will cause the disease known as simple goitre. The major form of thyroid hormone in the blood is thyroxine (T4), whose half-life of around one week is longer th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iodine
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Symptom
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicati ...

Medical Test
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment.

Meatpacking
The meat-packing industry (also spelled meatpacking industry or meat packing industry) handles the slaughtering, processing, packaging, and distribution of meat from animals such as cattle, pigs, sheep and other livestock. Poultry is generally not included. This greater part of the entire meat industry is primarily focused on producing meat for human consumption, but it also yields a variety of by-products including hides, dried blood, protein meals such as meat & bone meal, and, through the process of rendering, fats (such as tallow). In the United States and some other countries, the facility where the meat packing is done is called a ''slaughterhouse'', ''packinghouse'' or a ''meat-packing plant''; in New Zealand, where most of the products are exported, it is called a ''freezing works''. An abattoir is a place where animals are slaughtered for food. The meat-packing industry grew with the construction of the railroads and methods of refrigeration for meat preservation. R ...

Armour And Company
Armour & Company was an American company and was one of the five leading firms in the meat packing industry. It was founded in Chicago, in 1867, by the Armour brothers led by Philip Danforth Armour. By 1880, the company had become Chicago's most important business and had helped make Chicago and its Union Stock Yards the center of America's meatpacking industry. During the same period, its facility in Omaha, Nebraska, boomed, making the city's meatpacking industry the largest in the nation by 1959. In connection with its meatpacking operations, the company also ventured into pharmaceuticals (Armour Pharmaceuticals) and soap manufacturing, introducing Dial soap in 1948. Presently, the Armour food brands are split between Smithfield Foods (for refrigerated meat - "Armour Meats") and ConAgra Brands (for canned shelf-stable meat products - "Armour Star"). The Armour pharmaceutical brand is owned by Forest Laboratories. Dial soap is now owned by Henkel. History 1863–1970 Armo ...

Offal
Offal (), also called variety meats, pluck or organ meats, is the organs of a butchered animal. The word does not refer to a particular list of edible organs, which varies by culture and region, but usually excludes muscle. Offal may also refer to the by-products of milled grains, such as corn or wheat. Some cultures strongly consider offal as food to be taboo, while others use it as everyday food or even as delicacies. Certain offal dishes—including '' foie gras'', '' pâté'', and haggis —are internationally regarded as gourmet food in the culinary arts. Others remain part of traditional regional cuisine and may be consumed especially during holidays. This includes sweetbread, Jewish chopped liver, U.S. chitterlings, Mexican menudo, as well as many other dishes. On the other hand, intestines are traditionally used as casing for sausages. Depending on the context, ''offal'' may refer only to those parts of an animal carcass discarded after butchering or skinning ...

Slaughterhouse
A slaughterhouse, also called abattoir (), is a facility where animals are slaughtered to provide food. Slaughterhouses supply meat, which then becomes the responsibility of a packaging facility. Slaughterhouses that produce meat that is not intended for human consumption are sometimes referred to as ''knacker's yards'' or ''knackeries''. This is where animals are slaughtered that are not fit for human consumption or that can no longer work on a farm, such as retired work horses. Slaughtering animals on a large scale poses significant issues in terms of logistics, animal welfare, and the environment, and the process must meet public health requirements. Due to public aversion in different cultures, determining where to build slaughterhouses is also a matter of some consideration. Frequently, animal rights groups raise concerns about the methods of transport to and from slaughterhouses, preparation prior to slaughter, animal herding, and the killing itself. History Unti ...
