新疆伊犁维吾尔族和哈萨克族苯硫脲尝味能力测定

STUDY ON TASTE SENSITIVITY TO PHENYLTHIOCARBAMIDE(PTC)OF UIGURS AND KAZAKS IN XINJIANG

用阈值法对新疆伊犁的维吾尔族１２７４人，哈萨克族２０８０人的苯硫脲尝味能力进行了测定，结果表明，维吾尔族中味盲率为１５．２３％，味盲基因频率为０．３９０２，平均尝味阈值为６．９７±２．８７；哈萨克族中味盲率为１８．１２％，味盲基因频率为０４２５７，平均尝味阈值为６．４４±２．９４．经显著性检验，在维吾尔族和哈萨克族中，味盲率，平均尝味阈值和味盲基因频率在同－民族男女间无明显差异（Ｐ＞０．０５），在维吾尔族和哈萨克族两个民族间差异显著（Ｐ＜０．０１）．

A study on taste sensitivity to phenylthiocarbtalde(PTC) Was carried out on 1274 Uigursand 2080 Kazaks in Yili District of Xinjiang by using the threshold-method. The result showedthat percentage of non-tasters was 15.23% for Uigurs and 18.12% for Kazaks. Thetaste-blindness gene fi.equency of Uigurs and Kazaks was 0.3902 and 0.4257, respectively. Themean taste threshold and standard deviation were 6.97± 2.87 for Uisurs and 6.44± 2.94 forKazaks.There was a significant difference between Uigurs and Kazaks in taste-blindness gene fre quency, the percentage of non-tasters and the mean taste-threshold.
