“…Impact sensitivity measurements were made using a standard BAM Fallhammer. The residual iodine amount was characterized by a reported UV spectrophotometric method 26 for content determination of iodine using a VWR spectrophotometer UV-3100PC UV−vis. Potassium iodate (5.0 × 10 −5 mol/L), potassium iodide (2.5 × 10 −3 mol/L), starch (0.5%), sulfuric acid (1.0 mol/L), and distilled water were used.…”

“…In our work, the amount of residual iodine was characterized by using a reported UV spectrophotometric method (Supporting Information). 26 The iodine remaining on the media treated with decomposition products of after one month had decreased to 0.008 mg (a: 5 mg), 0.017 mg (a: 10 mg), 0.115 mg (a: 25 mg), and 0.200 mg (a: 50 mg) (Figure 9). From Table 2, the amount of I 2 released after decomposition or combustion of 5 is 49.67% which says 2.5 mg of I 2 is obtained when 5 mg of 5 is decomposed and so on.…”

Biohazards and chemical hazards as well as radioactive hazards have always been a threat to human health. The search for solutions to these problems is an ongoing worldwide effort. In order to control biohazards by chemical methods, a synthetically useful fused tricyclic iodine-rich compound, 2,6-diiodo-3,5-dinitro-4,9-dihydrodipyrazolo [1,5- a:5',1'- d][1,3,5]triazine (5), with good detonation performance was synthesized, characterized, and its properties determined. This compound which acts as an agent defeat weapon has been shown to destroy certain microorganisms effectively by releasing iodine after undergoing decomposition or combustion. The small iodine residues remaining will not be deleterious to human life after 1 month.

SynopsisThyroglobulins were extracted from the thyroid glands of one amphibia (Xenopus laevis), one ayes (chicken) and five mammals (whale, rat, hog, monkey and human), and purified by means of salting-out with ammonium sulfate followed by DEAE-cellulose chromatography. Sedimentation coefficients, electrophoretic mobilities, isoelectric points, immunochemical properties as well as iodine contents and amino acid compositions of all or most of these thyroglobulins were determined and the results were compared with each other. In spite of a great variety of animal species studied, these thyroglobulins were found to be rather similar in various respects, while species specificity was clearly indicated. Most distinct differences were observed among amphibian, avian and mammalian thyroglobulins, especially in amino acid composition, isoelectric point and immunochemical properties.

The Effects of Chronic Administration of Excess Iodine on Thyroidal Hormone Synthesis in the Chick

et al. 1969

View full text Add to dashboard Cite

SynopsisThe response of thyroid weight and iodine metabolism to excess ingestion of iodide was studied in the chick. Treatment of chicks with 1mg of iodide for 4 weeks induced a marked increase in thyroid weight. The radiochromatography of the 131I labelled thyroid hydrolysate showed that a single injection of carrier iodide resulted in a significant but transient reduction of a relative proportion of organic 131I as well as thyronine 131I and an elevation of the MIT/DIT ratio. After chronic treatment of chicks with excess iodide, the thyronine 131I proportion was still decreased notwithstanding the fact that the organic 131I proportion showed a return to normal and MIT/DIT was rather low. The increased thyroid weight and decreased thyronine proportion returned to normal 9 weeks after termination of the iodide feeding. In the goitrous chicks, the relative proportion of intrathyroidal 127I compounds were virtually identical with that of 131I, although the absolute amount of thyronine 127I was increased depending on the increase in total 127I content. There was no significant difference in both turnover rate of radiothyroxine and plasma thyronine 127I concentration between the goitrous and control chicks. It is suggested that these alterations of iodine metabolism seem to be closely related to the mechanism of goitrogenesis by excess iodide in chicks and may represent an inhibitory effect of iodide on intrathyroidal hormogenesis.
