不同年龄组儿童甲状腺测量值及其变化的研究

A STUDY ON THE MEASUREMENT OF EACH PART OF THE THYROID GLANDS RELATED TO DIFFERENT AGE CHILDREN

调查了90具童尸用状腺的基本形态,可分四型。其中以甲状腺由两侧叶及峡部组成者为最多,占50.22%。测量了甲状腺各部的长、宽、厚。分年龄组进行了数据的统计学处理,并计算出儿童与成人甲状腺各部相应值的百分比。结果显示:小儿甲状腺侧叶的长度和宽度在幼儿期(1—3岁)就已发育近成人的一半。随着年龄的增长,甲状腺各部的均值逐渐增加。除各部的宽度以及锥体叶的长度外,各相邻两组间同项均数的比较,经双侧T检验发现差异具有高度显著性(P<0.01)。

The morphology of 90 cases of thyroid glands in Chinese children have been investigated.They are classified into 4 types.The type which is com- oosed of rwo lobes connected with an isthmus appears to be the most com- mom type(50.2%).The different parts of thyroid glands have been measured in length,width and thickness.The data have been statistically processed according to different ages and the percentage of the average value of the lateral lobes between adults and the children has been calculated.The results show that he lengths and widths of two lateral lobes of children's thyroid glands are (?)pproximately half of those of adults when children are 1—3 years old.The average values for each part of the thyroid gland increase gradually with age and their diffrences between two neighbouriug groups in length and thickness vere statistically significant(P<0.01).
