A freshly prepared aqueous solution of iodine at a pH less than eight will contain mainly two forms of free iodine, namely diatomic iodine, I2, and triiodide, Ii,. The ratio of these two forms is determined by the concentration of iodide which is usually added to bactericidal prepaations for the purpose of increasing the solubility of the iodine. The solubility of diatomic iodine at 25 C is 0.0...

To the Editor: Normal thyroid function in fetuses and breast-fed infants, which is dependent on sufficient maternal dietary intake of iodine, is crucial for normal neurocognitive development.1 Children of mothers with severe iodine deficiency may have cretinism. Iodine deficiency affects more than 2.2 billion persons (38% of the world’s population) and is the leading cause of preventable mental...

I have been interested in iodine supplementation for years. I have a holistic family practice in West Bloomfield, Michigan. Michigan resides in the Goiter Belt of the United States where the soil is deficient in iodine. Although I long suspected iodine deficiency in many of my patients, my initial uses of potassium iodide gave suboptimal results. Some patients did improve, but many did not noti...

The benefits of iodine supplements during pregnancy remain controversial in areas with a mild-to-moderate iodine deficiency. The aim of the present study was to determine the effect of improving iodine intakes, with iodised salt (IS) or iodine supplements, in pregnant Spanish women. A total of 131 pregnant women in their first trimester were randomly assigned to three groups: (1) IS in cooking ...

The comparative resistance of bacteria and human tissue cells to antiseptics and other chemicals may be easily tested by tissue cultures under conditions which approximate those found in the living body. A comparative study shows that while human cells (connective tissue and wandering cells) are highly resistant to many antiseptics, they are in general more easily killed than bacteria (Staphylo...

Technetium-99 (Tc) and iodine-129 (I) are two long-lived fission products of high volatility, which makes their study in glass structure challenging. Both technetium and iodine have broad ranging multivalent chemistry and complex reactivity dependent on redox conditions; technetium and iodine redox may vary from Tc to Tc and from I to I. Relatively few studies have been done on their speciation...

At least two distinct mechanisms appear to be responsible for accumulation of iodine by the thyroid gland. The first, called the "iodide trap" by Vanderlaan and Vanderlaan (1), involves the concentration, presumably within the thyroid cells, of inorganic iodide obtained from the circulating blood. The second, called hormonal synthesis, involves the utilization of the trapped iodide for the synt...
