[10][11], Current regimens for treatment of thyrotoxicosis (including Graves' disease), when a patient is exposed to additional sources of Iodine, commonly include 500 mg potassium perchlorate twice per day for 18–40 days. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride. [13] Although 400 mg of potassium perchlorate divided into four or five daily doses was used initially and found effective, higher doses were introduced when 400 mg/d was discovered not to control thyrotoxicosis in all subjects. Fourth, thyroid peroxidase antibodies were not measured. Toutes les études effectuées avec des composés de perchlorate ont été considérées puisque c'est l'ion perchlorate qui est responsable des effets toxiques (ATSDR, 2008). Potassium perchlorate is the inorganic salt with the chemical formula K Cl O 4. Des coupures momentanées d’environ 5 minutes pourraient impacter les services en lig​​ne de la CNESST dimanche le 6 décembre entre 9 h et 11 h en raison d’un entretien technique. 1979 Jun;91(2):271-81. doi: 10.1530/acta.0.0910271. Like other perchlorates, this salt is a strong oxidizer and potentially reacts with many organic substances.

Thyroid Function by Perchlorate-Contaminated Water and Food Giuseppe Lisco 1, Anna De Tullio 2, Vito Angelo Giagulli 2,3, Giovanni De Pergola 4 and Vincenzo Triggiani 2,* 1 ASL Brindisi, Unit of Endocrinology, Metabolism & Clinical Nutrition, Hospital “A. Although rarely utilized today in the United States for treatment of a particular type of hyperthyroidism, thyroidologists are aware that perchlorate can inhibit iodine uptake by the thyroid gland, thereby reducing its production of hormone. (1997). Enlever les lentilles cornéennes s’il est possible de le faire facilement. Perchlorate (sometimes referred to as Perchlorate 7) is a hidden danger that has been rising to the surface over the last decade. Son ingestion cause une inhibition de l'utilisation de l'iode par la thyroïde et par conséquent de l'hypothyroïdie. The role of scintigraphy with dual tracer and potassium perchlorate (99mTcO4 & KClO4/ MIBI) in primary hyperparathyroidism: D. Rubello, G. Saladini, D. Casara. Braverman et al. Trapping, or uptake, can be blocked competitively by monovalent anions (e.g., potassium perchlorate). Plusieurs cas de mortalité ont été rapportés chez des patients traités avec des perchlorates. It impedes the accumulation of iodide in the thyroid, which blocks thyroid hormone production. Des symptômes gastro-intestinaux (nausées et vomissements) ont aussi été rapportés par des patients traités avec des perchlorates. Authors P T Männistö, T Ranta, J Leppäluoto. Based on that, read-across is possible to other perchlorate salt dissociating in water without any toxic cation. Votre session po​urrait être interrompue ou non enregistrée durant cette période. Un article de Wikipédia, l'encyclopédie libre. Perchlorate remains very useful as a single dose application in tests measuring the discharge of radioiodide accumulated in the thyroid as a result of many different disruptions in the further metabolism of iodide in the thyroid gland.

Bennett, Peter Wintzer, Saeed Akbar Sheikh, Patrizio Gallone "Chlorine Oxides and Chlorine Oxygen Acids" in. To completely block the uptake of Iodine-131 by the purposeful addition of perchlorate ions to a populace's water supply, aiming at dosages of 0.5 mg/(kg d), or a water concentration of 17 ppm, would therefore be grossly inadequate at truly reducing radioiodine uptake. Information on Registered Substances comes from registration dossiers which have been assigned a registration number. Risque avéré d’effets graves pour les organes à la suite d’expositions répétées ou d’une exposition prolongée (H372). Br Med J (13 May):1368–1369. Crossref, Medline, Google Scholar; Hobson QJG 1961. Perchlorate acts pharmacologically as a competitive inhibitor of thyroidal iodide uptake in mammals, but the impacts of perchlorate contamination in aquatic ecosystems and, in particular, the effects on fish are unclear.

Overview; Fingerprint; Abstract. Perchlorate can block the thyroid gland from taking up iodine, which it needs to make thyroid hormone. 1 Thyroid hyperplasia, an enlargement of the gland, can be seen in this setting and is an adaptive response by the thyroid to overcome the iodine uptake block. Il peut irriter la peau. Si l’irritation persiste, consulter un médecin. 6,7 The clinical study, however, studied only short-term exposure … The effect of 1000 ppm potassium perchlorate (KClO4), 1000 ppm potassium iodide (KI) or 1000 ppm propylthiouracil (PTU) in the diet on the development of thyroid tumors was studied histologically and biochemically in Wistar rats given a single ip injection of 280 mg of N-bis(2-hydroxypropyl)nitrosamine (DHPN) per 100 g body Lamm et al.

Furthermore, study data from human volunteers who were given perchlorate (at dosages up to 0.5 mg/kg/day for two weeks), and perchlorate-manufacturing workers, revealed no apparent change in various parameters of thyroid function despite exposure to the equivalent of anywhere from 200 to 17,500 ppb of perchlorate in water. Indication (1) Adjuvant Treatment of Type 1 Amiodarone-Induced Thyrotoxicosis (Type 1 AIT).

Changes in thyroid hormone levels in eggs and larvae and in iodide uptake by eggs of coho and chinook salmon, Oncorhynchus kisutch and O. tschawytscha. In the normal thyroid, organification promptly follows trapping. The NOAEL for potassium perchlorate is 1.18 mg /kg bw/d. perchlorate de potassium Des noms Autres noms chlorate de potassium (VII); l'acide perchlorique, sel de potassium; peroidin. Physicochemical properties Aplastic anaemia due to treatment with potassium perchlorate. Perchlorate ion concentrations in a regions water supply, would need to be much higher, at least 7.15 mg/kg of body weight per day or a water concentration of 250 ppm, assuming people drink 2 liters of water per day, to be truly beneficial to the population at preventing bioaccumulation when exposed to a radioiodine environment,[10][14] independent of the availability of Iodate or Iodide drugs.
