5. A nascent iodine solution can be used to assist the body in fighting off harmful organisms. Using an iodine tonic as a throat gargle is also helpful for a cough. Iodine also acts as an expectorant of mucous from the common cold and other respiratory ailments.
Early preparations of insulin were purified quite crudely from pancreas tissue extracted from animals-either pigs or cattle. Today, insulin is mostly made biosynthetically by recombinant DNA technology or 'genetic engineering'. Until the 1980s, all insulin was extracted from the pancreases of cattle and pigs. The sequence of amino acids (the building blocks that make up the protein) is slightly different in insulins from the different species. Compared to human insulin, porcine (pork) insulin has one different amino acid and bovine (beef) insulin three different amino acids.
Insulin is a hormone produced by the beta cells of the pancreas that permits glucose to enter cells and helps the body use glucose for energy. Insulin controls the amount of glucose in the blood. People with Type 1 diabetes must use manufactured insulin, usually in an injectable form (such as an insulin pen or an insulin pump), to replace the natural insulin that is no longer produced by their body.
