新疆蒙古族对糖精和乙酰水杨酸尝味能力的分析

对710名（男328人,女382人）新疆蒙古族进行了糖精和乙酰水杨酸尝味能力的检测分析。结果表明,蒙古人群中的糖精味盲率为4.648％,没有尝味能力的隐性基因频率为0.2156,具有尝味能力的显性基因频率为0.7844,平均尝味阈值为8.009 ±1.34（0.108mol/L）。乙酰水杨酸的尝味阈值分布出现了非常明显的双峰一谷分布,表明该性状是单基因决定的性状,谷底7号液（3.00X10-4mol/L）是味盲的界限,味盲的峰值在1号液（1.7X10-2mol/L）,尝味者的峰值在11号液（1.25X10-5mol/L）,味盲率为90.282％,。经x2检验,男、女性的味盲率元显著差异（P>0.90）,表明决定乙酰水杨酸尝味能力的基因位于常染色体,对该基因的显隐性等特点尚需通过家系分析进行确定。

Analysis of Saccharin and Aspirin Tasting Ability among Mongolians of Xinjiang

The saccharin and aspirin tasting abilities have been detected and analyzed in 710 individuals (328men, 382women)of Xinjiang Mongol. It is showed that the saccharin taste?blindness ratio among Mongolians was 4. 648% frequency of the recessive gene determining taste-lindness and the dominant gene determining taste ability was 0. 2156,and 0. 7844 respectively,and its mean testable threshold was 8. 00. 34 (0. 108mol/L). Distrition of aspirin tasting threshold appeared a distinct curve with double peaks and single bottom, and demonstrated the aspirin tasting ability was a monogenic character. Solution NO. 7 (3. 00 X 10-4 mol/L) at the bottom in the curve was the boundary of taste-lindness. The peak of taste-lindness was at the solution NO. 1 (1. 7 X 10-2 mol/L) ,and the peak of tasters was at the solution NO.11 (1. 25X 10-5mol/L) ,The ratio of aspirin taste-lindness was 90. 28%. The x2 test has been used to evaluate the statistical difference in aspirin taste-lindness ratio between male and fe-male, the result showed that there was no significant difference (P>0. 90) ,and the gene determining for aspirin tas-ting ability located on autosomes.
