SUMMARYDuring the World Twin Congress held at Eindhoven (Netherlands) in 1957 we tested 70 pairs of identical twins for their ability to taste para-ethoxyphenylthiocarbamide (EPTC). In 2 pairs a clear intra-pair discrepancy of taste was encountered. The tests with these 2 pairs were continued weekly for about six months. The result was always the same. One member of the pair found a bitter taste even in a solution 1:320,000 of EPTC; the other member considered even a solution 1:5,000 of this compound, i.e. a solution of the «taste blindness threshold concentration», completely tasteless. The former is a «taster», the latter is a «non-taster».A similar intra-pair discrepancy in taste with regard to phenylthiocarbamide (PTC) in pairs of identical twins has been found by Ardashnikov c.s. and by Rife.The ability to taste certain thiocarbamides without doubt being a hereditary property, the discrepancy of taste found must have an exogenic cause, the nature of which is unknown.The fact in question is discussed on the basis of the well-established bimodality of the taste threshold concentration/frequency curve for thiocarbamides. It is pointed out that the «non-tasters» of the pairs of identical twins under consideration must be regarded as «crypto tasters». Their taste threshold concentration lies on the «wrong» side of the (more or less arbitrarily adopted) «taste blindness threshold concentration» (1:5,000 for EPTC and PTC).The consequences of the existence of «crypto tasters» and also «crypto non-tasters» for work in the field of genetics with the aid of appropriate thiocarbamides are briefly indicated.

Aim. To compare bitter taste sensitivity to potassium chloride and parameters of bronchial patency in patients with bronchial asthma (BSA). Material and methods. The study involved 40 healthy volunteers, 82 patients with allergic asthma (ABA), 48 patients with non-allergic asthma (NABA). Spirometry was conducted. The method of Robert I.Henkin et al. (1963) was used to determine the threshold of taste sensitivity to the bitter taste (potassium chloride). Results. The bitter taste threshold was significantly higher in asthmatic patients, particularly in patients with allergic variant of the disease compared to healthy volunteers. Statistically significant inverse correlations were revealed between bitter taste threshold and those volume (VC: τ=-0,306; n=43, p<0,01) and speed parameters (FEV1: τ=-0,429; n=44, p<0,01; MEF50: τ=-0,419; n=43, p<0,01; MEF75: τ=-0,460; n=44, p<0,01) that were obtained after inhalation of β2-agonist (berotec). Moreover, negative correlation (τ=-0,221, n=56, p<0,01) was documented between bitter taste threshold and blood ionized calcium level. Non-allergic BA was characterized by significant negative correlation between bitter taste threshold and initial vital capacity. Conclusion. The above findings suggest that changes in bitter taste sensitivity and disorders of bronchial patency in allergic BA may have common pathogenetic mechanisms based in accordance with modern concepts on disturbances in signal transduction systems coupled to G-proteins.

Obsessive-compulsive disorder (OCD) is a severe anxiety disorder characterized by frequent obsessive thoughts and repetitive behaviors. Neuroticism is a vulnerability factor for OCD, yet the mechanisms by which this general vulnerability factor affects the development of OCD-related symptoms are unknown. The present study assessed a hierarchical model of the development of obsessive thoughts that includes neuroticism as a general, higher-order factor, and specific, potentially maladaptive thought processes (thought suppression, worry, and brooding) as second-order factors manifesting in the tendency toward obsessing. A total of 238 participants completed questionnaires assessing the examined constructs. The results of mediator analyses demonstrated the hypothesized relationships: A positive association between neuroticism and obsessing was mediated by thought suppression, worry, and brooding. Independent of the participant’s sex, all three mediators contributed equally and substantially to the association between neuroticism and obsessing. These findings extend earlier research on hierarchical models of anxiety and provide a basis for further refinement of models of the development of obsessive thoughts.

Abstract. To date, few studies have focused on perceived overprotection from the perspective of people with dementia (PwD). In the present examination, the association of perceived overprotection in PwD is examined as an autonomy-restricting factor and thus negative for their mental well-being. Cross-sectional data from the prospective DYADEM study of 82 patient/partner dyads (mean age = 74.26) were used to investigate the association between overprotection, perceived stress, depression, and quality of life (QoL). The analyses show that an overprotective contact style with PwD has a significant positive association with stress and depression, and has a negative association with QoL. The results emphasize the importance of avoiding an overprotective care style and supporting patient autonomy.

Canada's rate of suicide varies from province to province. The classical theory of suicide, which attempts to explain the social suicide rate, stems from Durkheim, who argued that low levels of social integration and regulation are associated with high rates of suicide. The present study explored whether social factors (divorce, marriage, and birth rates) do in fact predict suicide rates over time for each province (period studied: 1950-1990). The results showed a positive association between divorce rates and suicide rates, and a negative association between birth rates and suicide rates. Marriage rates showed no consistent association, an anomaly as compared to research from other nations.

SummaryAbetalipoproteinaemia is a rare disorder of apolipoprotein B metabolism associated with extremely low plasma concentrations of triglyce-ride. To discover whether the general positive association between factor VII and triglyceride levels extends to this condition, 5 patients were compared with 18 controls. All patients had a triglyceride below 100 μmol/l. Plasma unesterified fatty acid concentration was normal. Although factor IX activity was only slightly reduced (mean 88% standard) and factor IX antigen was normal, mean activated factor VII in patients was strikingly reduced to 34% of that in controls, a level similar to that found in haemophilia B. The patients’ mean factor VII activity and factor VII antigen were also significantly reduced to 54% and 63% of those in controls, respectively. Mean factor XI activity and tissue factor pathway inhibitor activity were reduced in patients to 70% and 75% of control values respectively, while factor XII, factor XI antigen, factor X, prothrombin and protein C were normal.
