Epidemiological investigation of endemic goiter in Fuling City

Limestone, little water iodine content of external environment in a low iodine status. According to the survey. 1980-1990 oyster, kelp, lotus decrease of sales, fell by the 184234kg 1980 1990 125118kg, will undoubtedly add to the impact of iodine. According to our survey. Tsui 1983, before the province's supply of the black and yellow wine container Zigong salt, black wine container of salt iodine content was 9.56mg/k8, is now measured at 5.5 times the stock of rock salt, they took to eat 15g of salt per person per day counted. Black wine container of salt a person eats each day by the iodine from the salt area 143.4pg, now eat the salt of iodine per person per day is successful only 26.1pg shows 1O years ago, iodine content of salt will be able to meet a single human daily physical requirements. Without a disease to occur. Low-iodine environment itself outside the case, eat a low iodine content of salt - will inevitably lead to a pain. Iodine content of salt reduction is caused by the city to the root cause of a disease epidemic. Second, popular features: the city's 36 wards township (town) rural students in the highest goiter rate was d4. o6. Ward residents feces iodine 55.43 ~ g / g. cr. A mild disease territorial city ward. Ward in the city wide coverage. Medical Students goiter disease with increasing age is obvious. Residents survey of thyroid patients less, patients are subject to Bute Man I degrees. Epidemic in the city suggested a short time, the iodine to take timely measures. Special effects can play good defense. (Participation in the work of this survey are: Tang safety too much sun and the moon over Rongcheng Yun Xie associated CHEN Pei-Feng Liu Shuqi Wang Qi Pu Zhaoli rhinoceros) (the switch 382) laboratory experiments not only confirmed the previous low-iodine in the rat pituitary TSH The number of cells was significantly higher than normal rats, and cell hypertrophy, cytoplasmic vacuoles of variable J. Moria ~ ty and other such cells known thyroid fine looking t hit well in the electron microscope, according to the site where secretory granules of different, will go to the thyroid cells were divided into two types】. Experimental observation car to the TSH cells and the increase in the number of mast is a direct result of iodine deficiency. Changes in cell morphology on the GH, peptone snow Xian, who had t use the orange G staining method to observe the long-methylthio pyrimidine pituitary GH cells in mice and found that hesitant than normal cells. This study found that pituitary GH cells in iodine-deficient rats was significantly smaller than the diameter of the normal rats, while effective amount less than the normal group, indicating that iodine deficiency causing decreased thyroid hormones, thus affecting the pituitary GH cell morphology and function . There experiments showed that the rats after removal of the thyroid, pituitary GH content and plasma GH decreased dimensions, the use of thyroid can be quickly restored after cable】. Which shows that thyroid hormone on the pituitary GH cell function is directly affected. In this experiment, LTH cell size and number, in the iodine group and the control group no significant change, which can briefly explain iodine deficiency in the rat pituitary gland morphology and function of LTH cells is not significantly affected.
