Iodine deficiency is the intelligence deformity that can be prevented
, its greatest danger is the damage causing intelligence and brain to be irreversible in development, this is a serious public health problem.
Our country is that the iodine lacks and endangers one of the most serious countries in the world, there are heavy patient and patient of spit of fland of 190,000 grams of 7 million local thyroid gland, there are 5,390,000 the disabled children of intelligence under the age of 14.
But understand iodine deficiency, we find this is a kind of intelligence deformity that can be prevented.
---Analysis of cause of disease - --It is an important reason that the environmental iodine lacks
The food is a main source of the iodine, but the iodine in the food depends on the soil and iodine amount in water. The scientists generally acknowledge unanimously the environmental iodine lack the most important pathogenic reason that is iodine deficiency.
We know, the thyroid gland lies in front of everybody's larynx, it is the body of endocrine glands, secrete the thyroxine.
The endocrine head of the department Professor Zhong LiYong of God Temple Hospital in Beijing says, the thyroxine that the thyroid gland secreted, though the trace, but the function on human growth is very important, right amount of thyroxine promotes protein synthesis, accelerate important function such as the exchange and utilization of organism growing, regulating energy and stabilizing structure and function of the central nervous system.
And the production of thyroid gland hormone must use globulin of thyroid gland and iodine as raw materials, globulin of thyroid gland is formated by thyroid gland, the iodine must depend on getting from the food. Once there are few people from iodine that is absorbed in the food, the thyroid gland this " processing factory " On meeting because of " Raw materials " Insufficient to cause " Drop in production " ,That is to make thyroid gland hormone in the human body formate and secrete reducing.
When the organism can't meet physiological demand while absorbing the iodine, can cause local goiter, can cause development to stagnate, dull-witted when being serious, for instance, the foetus can cause cretinism while lacking the iodine; Take in iodine, can cause high iodine goiter while being excessive, display the intersection of thyroid gland and the intersection of function and hyperfunction and some poisoning symptoms, these damages are referred to as iodine deficiency.
---Onset characteristic - --Influence crowds not to assign the the aged,middle aged person and young man
Lacking the iodine will have influence on every age crowd at stage, this view has already been accepted extensively by people.
If the foetus lacks the iodine, easy premature delivery, miscarry, even stillborn fetus, the probability of congenital malformation or abnormal state increases, will take place neural type grams of the intersection of spit of fland and disease ' Amentia, deaf and dump, convulsion paralysis and strabismus) Glue swollen type grams of the intersection of spit of fland and disease ' Amentia, short and small, neural movement obstacle,etc.) .
Neonate one lacks iodine, neonatal goiter, neonatal hypothyroidism,etc. happen.
Children and teenagers one lacks iodine, ill in the goiter, inferior clinical gram of spit of fland except happening, can cause amentia, physical development to lag behind, simple and deaf and dump, etc when being serious.
Lack the iodine in adulthood, goiter and complication, hypothyroidism, intelligence obstacle,etc. will generally happen.
