Dynamics of environmental supplementation of iodine : Four years' experience of iodination of irrigation water in Hotien, Xinjiang, China

Abstract: Hotien prefecture, Xinjiang Province, China, in the Taklamakan Desert, is an area of severe iodine deficiency. Because usual methods of iodine supplementation failed here, we began supplementation in 1992 with potassium iodate, which was added to irrigation water (Lancet 1994; 334:107-110). We report 4 y experience with this method in 3 townships that contained a total treated population of 37,000. Potassium iodate was dripped into irrigation water (to a concentration 10-80 microg/l) during a 2- to 4-wk period. During the 3 y that followed, no further supplementation was made, and iodine concentrations increased several fold in crops and plants, sheep and chicken thyroid glands, and meat and in urine of children 2-6 y of age and of women who were of childbearing age. Infant mortality decreased 50%, and sheep production increased 43%. Iodine repletion of soil through irrigation water is an effective and cost-efficient way of providing iodine in appropriate situations.

Iodine loss from iodised salt on heating

Abstract: Iodine deficiency disorders constitute a major public health problem in India. The national IDD control programme (NIDDCP) relies solely on iodine supplementation through fortification of common salt with potassium iodate. However, data regarding iodine loss due to high temperatures of cooking procedure is scarce. Using iodometric titration methods, we calculated iodine content of iodised salt samples subjected to incremental heat up to 350 degree Celsius. The results of the study indicate a gradual but minimal loss of iodine content from the iodised salt samples when subjected to high temperature with a maximum loss noticed being 18.5% at 350 degree Celsius. We conclude that there is minimal loss of iodine from the salt fortified with potassium iodate when subjected to heating (temperature normally attained during cooling process).

Treatment for upper respiratory tract infections with potassium salts

Abstract: A method for alleviating the symptoms of an upper respiratory tract infection in humans employs the application of a composition containing, in a pharmaceutically acceptable carrier, 0.1 to 3.0 weight percent of a potassium salt such as one or more of potassium acetate, potassium aluminate, potassium arsenite solution, potassium bicarbonate, potassium bisulfate, potassium bitartarate, potassium bromide, potassium carbonate, potassium chloride, potassium citrate, potassium gluconate, potassium glycerophosphate, potassium iodate, potassium iodide, potassium manganate, potassium permanganate, potassium phosphate monobasic, potassium phosphate dibasic, potassium phosphate tribasic and potassium phosphite.

Dry mixing technique for the large scale production of iodine fortified salt in India.

Abstract: Dry mixing technique was used successfully in three factories in India for the manufacture of iodine fortified salt. Permitted food additives, calcium carbonate and magnesium carbonate, were used with potassium iodate. The technology was smooth and free from any problem. Since the formerly conventional, but now superceded on analytical performance criteria, spray-mixing system was not used in the study, plants of the economics either batch mixing or continuous processes were more in evidence, and could be compared with avoidable spray mixing production performance data. The iodine fortified salt was free-flowing and retained the colour of the common salt. The iodine distribution was uniform (about 30 ppm). Long distance road transportation did not affect the iodine stability and its consistency. Storage studies showed satisfactory stability and the fortified salt had prolonged shelf-life beyond one year.

Kinetic method for the assay of levodopa in pharmaceutical preparations.

Abstract: A simple, rapid and accurate method for the analysis of levodopa using integral method, is described. The spectrophotometric measurements were recorded by measuring the increase in absorbance at 470 nm, when L-dopa was reacted with potassium iodate at room temperature. The kinetic parameters were calculated. The concentration range was valid from 60-700 ppm. The proposed kinetic method has been applied successfully to pharmaceutical preparations.

Feed for breeding fish

Abstract: PROBLEM TO BE SOLVED: To obtain feed for breeding fishes which contains a prescribed amount of iodine (or iodine compound), can prevent and treat the infections of cultured fish without causing problems on the body residue and drug resistance and is useful for yellowtails and eels with improved rate of rearing SOLUTION: For example, iodine or an iodine compound, for example, potassium iodide, potassium iodate or calcium iodide in an amount of 01-1% is added to a basic feed formulated with 713% of fish meal, 255% of wheat flour and 32% of vitamins and minerals (containing 02mg% of iodine) In a preferred embodiment, this feed for fish breeding is molded into pellets of 1-2mm size

Selenium-iodine-rich sugar

Abstract: The present invention relates to a selenium-iodine enriched sugar made up by adding micro quantity of sodium selenite and potassium iodate to white sugar. The mixing ratio of selenium and iodine elements contained in said product is rational, and said product is easy to eat, and can invigorate health of human body, and can prevent and cure the diseases caused by iodine and selenium deficiency.
