Abstract: Effective
salt iodization is a prerequisite measure to combat disorders of iodine
deficiency. However, it appears that the problem still exists. Iodized
table salts (fine and coarse retailed forms) which are available in the
Egyptian market were selected to test their effect, according to their
iodization level. Male albino rats were used, divided into four groups and
received oral salt solutions in different concentration levels for 90
days as follows; group I: served as control and received no salt solution,
group II: referred to low iodine dose, group III: as moderate iodine dose,
group IV: expressed as high iodine dose. Body weights were recorded and blood
samples were collected, at the start of the study and at 1 month interval for 3
successive months’ and processed for determination of thyroid hormones, mainly
plasma free T3, fT4, TSH, fructosamine, insulin, and qualitative C-reactive
protein (CRP), being followed by histological examination of thyroid tissues.
Salt intake of different iodine concentrations induced significant increase in
TSH, fT4, and CRP. However, fT3, fructosamine, and insulin demonstrated
significant decrease.
