Effects of Iodine and Iodine-Containing Compounds on Thyroid Function

Medical Clinics of North America, 1985
This article deals with iodine metabolism and the consequences of iodine deficiency and iodine excess. The mechanisms underlying the clinical presentation of these two conditions as well as the clinical implications, both diagnostic and therapeutic, are discussed.

A New Iodine Compound for Cholecystography

Radiology, 1927
THE extensive use of sodium tetrabromphenolphthalein and sodium tetraiodophenolphthalein in cholecystography, since they were first introduced by Graham and his associates, has shown that these two compounds will serve efficiently. Intravenous administration of these drugs for cholecystography has the advantage of assuring that a specified dose has ...

Gas chromatographic determination of iodinated compounds

Analytical Biochemistry, 1969
The qualitative and quantitative gas chromatographic evaluation of a large variety of iodinated substances (iodoamino acids and their side chain and position analogs, intermediates in the synthesis or degradation of the thyroid hormones, and related compounds) is described. As little as a few hundred picograms can be determined accurately in most cases

Thyroidal iodinated compounds in nodular goitre

Clinica Chimica Acta, 1968
Abstract The iodinated compounds in the nodular and paranodular tissues of 19 cases of nodular goitre have been separated by thin-layer chromatography. A high monoiodotyrosine/di-iodotyrosine ratio was found in “cold” nodules, and a low one in “hot” nodules.

Iodine Compounds in the Atmosphere

2005
The current understanding of iodine sources in the atmosphere, the abundance of atmospheric iodine compounds and their chemistry are reviewed. Besides CH3I, several other organic iodine compounds of biological origin, such as CH2I2, CH2ClI and C3H7I have been detected in ocean water. Due to their low solubility the water can become super-saturated with

Hypervalent Iodine Compounds with Tetrazole Ligands

The Journal of Organic Chemistry, 2018
Hypervalent iodine compounds with two I-N bonds, containing 5-substituted tetrazoles as the ligands PhI(N4CR)2 (R = CH3, C6H5, and 4-CH3C6H4), were synthesized from PhI(O2CCF3)2 or PhICl2 and the corresponding tetrazole potassium salts. Alternatively, PhIO was reacted with the free tetrazoles, and the reactions afforded either PhI(N4CR)2 or, in most ...

Exchange Reactions of Iodine Compounds

Nature, 1937
JULIUSBURGER, Topley and Weiss1 found by the artificial radioactive indicator method that an exchange takes place between sodium iodide (c. 0.5M) and methyl iodide (c. 2M) in alcoholic solution at room temperature ; the exchange is complete in a minute or two.
