为了观察研究国人甲状腺、肾上腺及胸腺在胚胎期的发育程度,本文取13—42周的新鲜胎儿的甲状腺51例,肾上腺64例、胸腺68例,用精度为0.1g的天平称其重量。以每4周为一组,共分8组或7组(甲状腺7组,肾上腺、胸腺各8组)所得数据经统计学处理,算出各个脏器的组 内平均值(x),标准差(s),标准误(sx),95％可信值范围(x+1.96sx),并将脏器重量比体重乘以100％示脏器相对重量,其结果见表1、2、3。下面仅就各个脏器分述如下。 通过分析甲状腺的重量及相对重量发
In order to observe and study the thyroid, adrenal and thymus in human embryos in the degree of development, this paper takes 13 to 42 weeks of fresh fetus thyroid 51 cases, adrenal 64 cases, thymus 68 cases, with a precision of 0.1g weighing the balance. Each group of 4 weeks was divided into 8 groups or 7 groups (thyroid 7 groups, adrenal gland, thymus 8 groups) the data were statistically processed to calculate the average value of each organ group (x), standard deviation s), standard error (sx), 95% credible value range (x + 1.96sx), and the organ weight multiplied by 100% body weight relative weight, the results in Table 1,2,3. Below only for each organ is described below. By analyzing the thyroid weight and relative weight hair
