Distribution of non-tasters for phenylthiocarbamide and high sensitivity to quinine hydrochloride of the non-tasters in Japanese.
نویسندگان
چکیده
The percentage of non-tasters for phenylthiocarbamide in 915 Japanese students was 9.4%. The thresholds of the edge and back of the tongue to quinine hydrochloride were significantly smaller in the non-tasters than in the tasters. The thresholds of any tongue portions to NaCl, acetic acid or sucrose did not differ between the tasters and the non-tasters.

Introduction: The ability to taste Phenylthiocarbamide (PTC), has been long studied from genetics, epidemiologic and evolutionary point of view. This ability is associated with the ability of tasting other bitter substances which mostly are toxic. Natural selection is involved in the maintenance of the allelic frequency of PTC. Variation in the frequency of tasters and non-tasters could reflect...
متن کاملGustatory differences in hypothyroid and hyperthyroid tasters and non-tasters.
Gustatory differences in Phenylthiocarbamide (PTC) tasters and non-tasters were studied in hypothyroid and hyperthyroid subjects. After presenting for PTC sensitivity, gustatory responses to 7 dilutions of test solutions for glucose (sweet), sodium chloride (salt), citric acid (sour) and quinine sulphate (bitter) were studied in PTC tasters and non-tasters. The intensity and pleasantness respon...
متن کاملRelationships between threshold-based PROP sensitivity and food preferences of Tunisians.
The extent to which taste responses--and notably the genetically determined sensitivity to 6-n-propylthiouracil (PROP)--influences food preferences and food use is still a matter of debate. We addressed the issue on the basis of a behavioural and anthropological study performed in Tunis in 1999. The working sample consists of 123 adults of both sexes (38 men, 85 women), aged 19-59, in various s...
متن کاملBinary taste mixture interactions in prop non-tasters, medium-tasters and super-tasters.
It is generally assumed that the mutual, but asymmetric, suppression of the components in binary taste mixtures is an invariant property of the human psychophysical response to such mixtures. However, taste intensities have been shown to vary as a function of individual differences in sensitivity, indexed by the perceived bitterness of 6-n-propylthiouracil (PROP). To determine if these variatio...
متن کاملPossible relationship between phenylthiocarbamide taste sensitivity and epilepsy.
The study was based on the data of a sample of 400 epileptic patients (200 idiopathic and 200 symptomatic) and 100 normal healthy individuals serving as controls. The PTC threshold distribution was bimodal. The number of non-tasters among idiopathic epileptics (35.5%) and symptomatic epileptics (32.5%) was significantly higher than controls (20%). The relative incidence of non-tasters in idiopa...
