The relat~ion of iodine to thyroid metabolism has rcccived a large amount of study, but the supply of iodine in food materials had been given no systematic attention until taken up by Forbes.’ What influence its tot,al absence in the diet might have on the development of an animal is problematic, but there has not been a lack of opinion t!hat such an absence or low supply in the foods from cert...

Transport of iodine in the mammary gland into breast milk plays a central role in various fields of prevention of thyroid diseases. First, a sufficient content of iodine in the mother's milk is necessary for normal brain development in the breastfed child. This is attained by expression during lactation in the mammary gland of the sodium iodide symporter (NIS), also responsible for iodine trans...

Introduction: Orthodontist must take precautionary measures to protect patients from cross-infection by contaminated materials received the manufacturers. To minimize incidence of prior bonding an invitro study was done assess antibacterial activity chlorhexidine, povidone iodine and glutaraldehyde. Aim: compare 2% 5% glutaraldehyde on orthodontic bonding. Materials methods: A total 36 samples ...

Iodine is an essential micronutrient required for normal growth and neurodevelopment; thus, an adequate intake of iodine is particularly important for pregnant and lactating women, and throughout childhood. Low levels of iodine in the soil and groundwater are common in many parts of the world, often leading to diets that are low in iodine. Widespread salt iodization has eradicated severe iodine...

Iodine deficiency has multiple adverse effects on growth and development because of inadequate thyroid hormone production. Four methods are generally recommended for assessment of iodine nutrition: urinary iodine concentration, thyroid size, and blood concentrations of thyroid-stimulating hormone and thyroglobulin. Iodine intakes < or = 1 mg/d are well tolerated by most adults, because the thyr...

Perinatal exposure to excess iodine can lead to transient hypothyroidism in the newborn. In Japan, large quantities of iodine-rich seaweed such as kombu (Laminaria japonica) are consumed. However, effects of iodine from food consumed during the perinatal period are unknown. The concentration of iodine in serum, urine, and breast milk in addition to thyrotropin (TSH), free thyroxine (FT(4)), and...

High total iodine content and significant amounts of iodinated amino acids, but not of thyronines, have been reported in milk of various species. Since the human neonate requires thyroxine-like iodine compounds for central nervous system development, analyses of thyroxine-like iodine compounds such as butanol-extractable iodine of colostrum or early milk were indicated. Four samples of human mi...

This chapter provides an overview of the disorders caused by iodine deficiency. Extensively referenced, it includes data on dietary sources of iodine, goitrogens, the effects of iodine deficiency throughout the lifecycle, the pathophysiology of iodine deficiency, as well as strategies for control and monitoring of the iodine deficiency disorders, such as iodized salt and iodized oil. It emphasi...

Iodine imparts strong contrast to objects imaged with electrons and X-rays due to its high atomic number (53), and is widely used in liquid form as a microscopic stain and clinical contrast agent. We have developed a simple technique which exploits elemental iodine's sublimation-deposition state-change equilibrium to vapor stain specimens with iodine gas. Specimens are enclosed in a gas-tight c...

BACKGROUND AND OBJECTIVE A nationwide survey of schoolchildren was conducted to detect regional differences in urinary iodine excretion in Latvia and to compare the results with data from the newborn thyroid-stimulating hormone (TSH) screening database as well with the results of a similar study performed in Latvia 10 years ago. MATERIALS AND METHODS We conducted a cross-sectional school-base...
