Results were expressed in terms of rat LH standards using the following standards: for LH iodination: r-LH-I10, reference preparation rat LH-RP-3, (AFP7187B) and anti-rat LH-S11 (AFPC697071P) [41].
Thyroperoxidase a 105kDa glycoprotein which catalyses iodine oxidation and thyroglobulin tyrosyl iodination reactions in the thyroid gland and is essential for active thyroid hormone T4 and T3 synthesis.
It has been reported that salivary glands at least in experimental animals are closely linked with various endocrine organs and disturbance of endocrine glands can affect the morphological or functional aspects of the salivary glands.7 Thyroid hormone is produced by the follicular cells of the thyroid gland through iodination of thyrosine residues in the glycoprotein thyroglobulin.8 3, 3, 5-triiodo-L-thyronine (T3) is the meta-bolically active form of the thyroid hormone.This hormone plays important roles in normal growth and development, neural differentiation, inflammation, proliferation and metabolic regulation in mammals.9 It is involved in regulation of many physiological processes that can differ between tissues or developmental stages or in response to environmental ques.
The third axis is Brazilian government Prevention and Control of Nutrition Disorders, which include National Iron and Folic Acid Supplementation Program, National Vitamin A Supplementation Program, Fortification Strategy for Infant Feeding with Micronutrient Powders (called NutriSUS) and salt iodination. These programs are developed at municipal levels.
Increased levels of intracellular [Ca.sup.2+] and PLC activity play a major role in the regulation of [H.sub.2][O.sub.2] production, thyroglobulin (Tg) iodination and iodide efflux, while adenylate cyclase and cAMP regulate transcription of sodium-iodide symporter (NIS), Tg and thyroid peroxidase (TPO), as well as iodide uptake (4,5).
