内蒙古地区蒙古族和汉族苯硫脲尝味能力的测定

Determination of Taste Sensitivity of Phenylthiourea in Mongolian And Han of Inner Mongolia

本文采用Harris和Kalmus改良阈值法测定了内蒙古地区2034例(蒙古族998例,汉族1036例)苯硫脲尝味阈值。以4号液为味盲界限。蒙古族中味盲者116人(11.62%),尝味者882人,平均尝味阈值9.29±1.44;汉族中味盲者104人(10.04%),尝味者932人,平均尝味阈值9.33±1.44.味盲率在蒙、汉民族间、男女性别间、内蒙东、西部地区间均无显著性差异。苯硫脲平均尝味阈值在蒙、汉民族间也不存在显著差异,但同一民族的地区性差异显著,男女性差亦极其显著,女性比男性大约低0.48～0.51。

The taste threshold for Phenylthiourea among 2034 cases (998 cases for Mongolian, 1036 cases for Han) in Inner Mongolia region were determined by means of Harris-Kalmus^1 modified threshold. By using No.4 solution as a boundary line of taste-blindness, the results were shown that 116 cases taste-blindness (11.62%) and 882 taster, with an average threshold of 9.29±1.44 among Mongolians; 104 cares taste-blindness (10.04%) and 932 taster, with an average threshold of 9.33±1.44 among Hans. There was no difference in taste-blindness frequency between Mongolian and Han, male and female, between that in the eastern part and in the western part of Inner Mongolia. And in the average taste threshold for Phenylthiourea there was no difference between the two nations, but a regional difference existed in identical nationlity, and a very significant difference were shown between the males and the females that the taste threshold of females was 0.48—0.51 lower than that of the males.
