河北省汉族人苯硫脲尝味能力测定与分析

The Determination and Analysis of Tasting Phenythio carbamide (PTC) Ability in Han People of Hebei

测定了１００８名（男５１０名，女４９８名；儿童６７９名，成人３２９名）汉族人的苯硫脲（ＰＴＣ）尝味阈值。从中检出味盲者７５人，味盲率７．４４％，受试人群无显著性别差异。尝味者９３３人，平均尝味阈值（ｘ±ｓ）为１０．３４±１．４９，在儿童中无性别差异，但在成人中女性明显低于男性。儿童的味盲率和平均尝味阈值均低于成人。并算得被试者中的隐性味盲基因（ｔ）频率为０．２７２８，显性基因（Ｔ）频率为０．７２７２。

PTC taste threshold of 1008 Han people(male 510,female 498;children 679,adult 329)was determined in Hebei province.The result showed that the rate of non taster was 7.44%;there was no significant difference between sexes.Mean taste threshold( ±s ) of 933 taster was 10.34±1.49,it wasn't related to sex in children,and that of adult female was evidently lower than that of male.The rate of non taster and the mean taste threshold of adult was higher than childern's.Recessive(t) and dominant(T)non taste gene frequency of the people determined were respectively calculated to be 0.272 8 and 0.727 2 using Hardy Weinberg's low.
