5, 145 persons, amounting to 92.2% of the population, were examined. 22.7% of persons examined contracted endemic goiter. There were two peaks of incidence of endemic goiter in age distribution, one at 15 to 19 years and the other at 50 to 59 years old. The incidence of endemic cretinism was 2.7%, all cases belonging to nervous type; 54% of cases were at 30 to 39 years. Measurement of serum total T_4, T_3 and TSH by radioimmunoassay and the urine iodine revealed normal ranges in most of them. The mean level...

The incidence of endemic cretinism was 2.7%, all cases belonging to nervous type; 54% of cases were at 30 to 39 years. Measurement of serum total T_4, T_3 and TSH by radioimmunoassay and the urine iodine revealed normal ranges in most of them. The mean level of iodine in drinking water was very low, being only 0.825 μg/1, The mean iodine content of the iodized salts (4.85 μg/kg) was lower than the standard. There exists a positive correlation between the incidence of endemic goiter and that of cretinism A negative correlation is found between the incidence of either and the iodino content of the drinking water.

受检5145人,普查率为92.2%。调查结果,甲状腺肿患病率为22,7%;7至14岁儿童甲状腺肿大率为46.90—50.95%。甲状腺肿患者年龄分布呈15—19岁组和50—59岁组二个高峰。地方性克汀病患病率为2.7%,属神经型。克汀病患者中30—39岁组占总数的54%。血清T_4、T_3、TSH放射免疫分析和尿碘测定结果大多数于正常范围。饮用水含碘量测定,其平均值为0.825微克碘/升,甚低。加碘食盐的含碘量测定,平均值为4.85微克碘/公斤,低于标准。两病的患病率间呈正相关关系,而与水碘含量呈负相关关系。调查表明两病的病因基础是缺碘。

A simple method for spectropho-tometric determination of iodine in kelpis presented. The analytical conditionshave been evaluated, such as the wave-length of maximum absorption, rangeof concentration in accord with Beer'slaw, the optimum acidity and effectof time on the absorbance, etc. Theprocedures are as follows. The sample is carbonized withsmall amount of potassium hydroxidesolution (10 N), then ashed in a mufflefurnace at 550℃ for 30 minutes. Theresidue is oxidized with potassiumdichromate in an acidic solution. Theiodine is extracted by chloroform in aseparatory funnel and the absorbancemeasured at 510 nm by type 721 spec-trophotometer. The linear relationshipbetween the absorbances of solutionscontaining iodine and their respectiveconcentrations, ranging from 0.01 to1.0 mg/10 ml, is observed. The accu-racy and precision of the method provesto be satisfactory. The recovery is 95%-105%, and the coefficient of yariationless than 3%. The absorbance of chlo-roform containing iodine is stablewithin 8 hours. This method requiresonly small amount of common reagents,and no special equipment is needed.Itcan be applied in most general labora-tories. The kelp productions in the coastalarea of China are collected, includingZhoushan Islands, Qingdao, Qinhuang-dao, Dalian, Dandong, Fujian, Guang-dong, etc. By this method the iodinecontents of these samples are measured,ranging from 2.69 to 7.45 g/kg witha mean value of 5.13 g/kg(dry weight). According to the results obtainedin our laboratory for laver, mussel,jellyfish, it is indicated that thismethod can also be applied to determinethe contents of iodine in other marineproducts.

A new method for the determination of iodide and organiciodine compounds using a gold-coated quartz piezoelectric crystal is developed. Iodine is extracted into the carbon tetrachloride phase after decompositon of thesample by oxygen flask combustion method. The frequency of the crystal is decreased when iodine is adsorbed on the gold electrode of the crystal from the carbon tetrachloride solution. The only interference is found from bromine. The linear range is 1 × 10~(-7)~3 × 10~(-5)M. Reversibility of the detector is achieved by immersion in ammonia water for 5~10 min. The method is suitable for determining iodine content in organic-iodine compounds and for determination of organic-iodine compounds in aqueous solutions, urine and blood.
