长期高氟环境对肤纹的影响

本文对 32 2例高氟区人群的肤纹进行了分析 ,并与正常对照组及缺碘区人群作了比较。结果表明 :高氟区人群的肤纹参数与正常对照组有明显的差异 ,其中尺箕纹 (Lu)、变异型掌褶等项参数高于对照组 (P<0 0 1 ) ;而斗型纹 (W )、TFRC、TH I1 、I4区真实花纹出现率低于对照组 (P <0 0 1 )。高氟区人群的Lr 出现率、TFRC、变异型掌褶及掌部真实花纹出现率等指标与缺碘区人群基本相似。作者认为 ,长期高氟环境可能对居地人群遗传性状产生影响 ,肤纹出现的差异是其表达形式 ,同一地区人群遗传性状的差异可能与外环境微量元素的摄入水平有一定关系。

EFFECTS OF LONG-TERM HIGH-FLUORINE ENVIRONMENT ON DERMATOGLYPHICS

The dermatoglyphic features of 322 cases in high-fluorine area were analysed.The acquired data were compared with that of the control group and that of the people of serious iodine deficiency (area.)The results showed some statistical differences in the dermatoglyphic parameters between the people of high-fluorine area and control group.The ulnar loop(L~u),variation type of palmar creases in the people of high-fluorine area are more abundant than those in control group (P<0.01).The whorl(W),TFRC,and percent frequencies of true patterns in TH/I 1 and I 4 in the people of high-fluorine area are less than control group (P<0.01).The dermatoglyphic parameters of the people in high-fluorine area were similar to those of the people of iodine deficiency area in frequencies of L~r,TFRC,variation type of palmar creases and percent frequencies of true pattern in palm.We suggested that long-term high-fluorine environment has an effect on the genetic characteristics of the people in such area.The difference of hereditary features of the people in the same area might have relation to the amount of intake of the micro-elements of external environment.
