Iron

Iron (Ferrum, Fe) is a chemical element of group VIII of the periodic system of elements of D. I. Mendeleyev. Serial number 26, atomic weight 55,84. In connection iron is usually two or three, rarely hexavalent.
Iron is one of the most common metals. In the form of complex organic compounds of iron is part animal and vegetative organisms. Pure iron is white with grey shade malleable metal;
temperature of melting 1539 degrees, the density 7,86. Iron is oxidized in air (rust), easily communicates with acids and forms a large number of complex compounds. Because of variable valence iron compounds thereof may participate in oxidation-reduction reactions. This property defines the biological importance of iron. In mammals iron is the main component of the respiratory enzymes and hemoglobin. In the human body contains about 5 g of iron, 70% of which is in the structure of hemoglobin. Daily need in iron - 6 - 12 mg of Iron is excreted from the body through the gastrointestinal tract. Iron is found in many foods: lentils, peas, beans, bread, cereals; in smaller quantities - in vegetables, fruits.
There are several artificial generated radioactive isotopes of iron. Practical importance Fe59 with a half-life of 45 days with beta - and gamma-radiation (see Beta-rays, Gamma rays), and to a lesser extent Fe55 with half-lives of 2.9 years, with a very weak x-ray emission (see). Using Fe59 studied the iron metabolism in the body and its distribution in tissues, sharing hardware between the mother and the fetus, and also the questions connected with formation of hemoglobin and erythrocytes, a question about the survival of red blood cells in the blood Bank, about the age of erythrocytes affected malaria Plasmodium, etc.
Radiation therapy with radioactive iron is usually not applied.

Iron supplements

As medicines are used mainly connection ferrous iron (ferrous), which is better than drugs trivalent iron (oxide), are absorbed and less irritate the mucous membrane of the gastrointestinal tract. An essential factor in ensuring the absorption of iron, is a hydrochloric acid of the gastric juice, which translates iron supplements in the form of soluble ferric chloride. So when gastric secretory deficiency simultaneously with iron preparations appoint gastric juice or divorced hydrochloric acid.
Iron preparations are used for treatment of hypochromic (iron deficiency) anemia of different etiology (postgemorragical, chlorosis and other).
Iron restored (Ferrum reductum). Designate powder, pills and tablets (0.2 g) 0.5-1.0 g 3-4 times a day after meals.
Ferrohematogen (Ferrohaematogenum) tablets (0.3 or 0.5 g), containing iron restored (11 -12%) and dried blood of cattle, proteins which improves absorption and effectiveness of iron. Take 1 table. 3-4 times a day.
Iron glycyrrhizinate (Ferri glycerophosphas, Ferrum glycerophosphoricum). Appoint powder and tablets (0.5 g) 1 g 3-4 times a day.
Iron lactate (Ferri lactas, Ferrum lacticum). Appoint powder and pills 1 g 3-4 times a day.
Hemocyanin (Haemostimulinum) - preparation of the blood of cattle, plus 50% of iron lactate and 1% of copper sulfate. Appoint powder and tablets (0.3 and 0.6 g) 0.6 g 3 times a day.
Iron ferrous sulfate (Ferrum sulfuricum охуdulatum, Ferrosi sulfas). Designate powder (capsules), 0.3 - 0.5 g 3-4 times a day after meals.
Pills Blo (Tabulettae Blaudi). Contain 0,028 g iron ferrous sulfate. It is administered 1 tablet 3-5 times a day after meals.
Ferrogal (Ferrocalum) - tablets containing 0.2 g iron ferrous sulfate; 0.1 g of calcium frukostbuffe, 0.02 g letitina. Assign 2 to 6 tab. 3 times a day.
The solution malic iron alcohol-water (Solutio ferri pomati spiritus-aquosa). Appoint 30 ml 3 times a day after meals.
Iron-ascorbic acid (Acidum ferroascorbinicum), used in tablets (0.5 g) 0.5-1 g 2-3 times a day.
Piramid (Ferramidum) - the complex compound of iron chloride with PP. Assign into tablets (0.02 g and 0.1 g) to 0.1 g 3 times a day, and intravenous (slowly!) 2-4 ml of 2% solution of the day (ml to 2 ml of 2% solution 0.25% solution of ascorbic acid).
Verkopen (Fercovenum) consists of saharat iron glukonata cobalt and solution of carbohydrates, contains in 1 ml of 0.02 g of iron and 0.09 mg cobalt. Injected (within 8-10 minutes) 1 per day. The first two injections 2 ml, Altai 5 ml of the Preparation is applied only in a hospital. In overdose possible, chest pain, back pain. Verkopen contraindicated in coronary insufficiency, hypertension in later-stage liver damage.
