严重缺碘对体质及遗传性状影响的研究

对严重缺碘地区一个容貌特殊,身材较矮,智力低下的人群进行了体质特征及遗传性状的研究,并与国内有关本地区的调查资料进行了对照,提出人类体质特征和遗传性状除与人种、地理环境异同直接相关外,人体不可缺少的微量元素的摄入水平在一定程度上对其也产生影响。并且认为同一人种、民族居住同一地理位置所产生的体质差异应从水文、地质、生活方式、生活水平的不同进行综合分析。

THE STUDY OF THE EFFECTS OF SERIOUS IODINE DEFICIENCY ON PHYSICAL AND GENETIC CHARACTERISTICS

A study on a group of people in the serious iodine deficiency area in West Hubei was performed. The results are as follows: 1. The Physical Characteristics The cephalic index is of mesocephaly type in both sexes. The facial form in most cases is of ovoid type. The morphological facial index mostly belongs to leptoprosopy type in males and females. The nasal index belongs to mesorrhiny. There are no Mongolian fold in half of the samples. Double eye-lids are observed at high percentage. The palpebral opening is from the middle to stenotic type and its direction is sloping upward laterally. The statures are rather short, averaging 159.04 cm for male and 149.73 cm for female respectively. 2. The Blood Groups The distribution of ABO blood groups is O>B>A>AB, and that of the MN blood groups is MN>M>N. 3. The Dermatogiyphics The atd angle is 43.18. The variation type of palmar creases is 34.25%, including simian line-9% and other types-25.25%. 4. The Taste threshold for PTC The taste blindness frequency is fairly high and average taste threshold is fairly high too. Compared with the normal group of people in the iodine nondeficiency area, the results show that there are obvious differences between the people living in serious iodine deficiency area and iodine non-deficiency area.
