Im Mittelpunkt dieser Untersuchung steht die Überprüfung des interaktionistischen Ansatzes, der den Ärgermodellen von Novaco (1978) und Spielberger (1988) zugrunde liegt. Anhand zweier Stichproben, einer Manager- und einer Leistungssportlerstichprobe (N =97 bzw. N =74), sollen zudem unterschiedliche ärgerauslösende Situationsklassen und Ärgerdimensionen aufgezeigt werden. Als Ergebnisse sind festzuhalten: Eine Ärgerreaktion läßt sich in eine physiologische, eine kognitive und zwei verhaltensmäßige Komponenten differenzieren. Bezüglich der letzteren wird die Dimensionierung des Ärgerausdrucks in zwei unterschiedliche Komponenten, Anger out und Anger in, bestätigt. Die Bereichsspezifität der Ärgerneigung konnte durch eine Dimensionierung von Ärgersituationen nur in eingeschränktem Maße nachgewiesen werden. Die Ergebnisse zur Gültigkeit des unteraktionistischen Ansatzes differenzieren zwischen der gewählten Auswertungsmethoden. Lassen sich die prozentualen Varianzanteile bei den Stichproben in Richtung eines unteraktionistischen Modells auslegen, so sind die Generalisierbarkeitskoeffizienzen zumindest bei einer Stichprobe nicht in dieser Eindeutigkeit zu interpretieren.

Human cutaneous mast cells and their experimental model rat peritoneal mast cells, can be stimulated by an IgE-dependent process or by peptides through the direct activation of G proteins. Both activation pathways lead to the increase of cytosolic Ca2+ level. This increase in dependent of the mobilisation of intracellular calcium stores of the endoplasmic reticulum involving the stimulation of IP3-sensitive calcium channels. Mast cells are characterized by the absence of calcium channels in the plasma membrane. Oxatomide has been synthetized as an analog of cinnarizine. However oxatomide is inactive on current calcium channels. In mast cells, oxatomide inhibits the increase of cytosolic calcium elicited during mast cell activation. Consequently mast cell exocytosis is inhibited altogether with the release of newly synthetized mediators. The authors propose several putative targets for oxatomide in mast cells. The therapeutic effect of oxatomide is also related to its property to antagonize the effects of anaphylactic mediators on their selective receptors. [less ▲]

The neuropeptide substance P, the venom peptide mastoparan and the synthetic polyamine compound 48/80 activate rat peritoneal mast cells, leading to rapid histamine release by exocytosis. Although these effects are inhibited by pertussis toxin and involve a transient increase in IP3, no selective membrane receptors have been identified. However, it has recently been shown that these compounds activate G proteins in vitro. Here Yves Landry and colleagues discuss the proposal that direct activation of G protein is the physiological mechanism of action of substance P on rat peritoneal mast cells, this mechanism being mimicked by mastoparan and 48/80, and possibly by other cationic amphiphilic peptides such as kinins. These compounds might be of help in defining the interaction between membrane receptors and G proteins. [less ▲]

Bradykinin, kallidin (Lys-bradykinin) and [Thi 5,8, D-Phe7]-bradykinin, a functional B2 antagonist, induce histamine release from rat peritoneal mast cells. The histamine release is dependent upon added calcium when mast cells are placed in calcium-free medium 30 min before being triggered with the kinins. Histamine release was dose-dependently inhibited by pertussis toxin (1-100 ng/ml) and by benzalkonium chloride (0.1-3 micrograms/ml). The efficiency of ionophore A23187 on histamine release was affected neither by pertussis toxin nor by benzalkonium chloride. The parallel response of rat peritoneal mast cells to kinins and to substance P suggest that these peptides have the same mechanisms of action i.e. activation of a pertussis toxin-sensitive G protein and of phospholipase C defining a peptidergic triggering pathway of mast cells.

To understand the function of murine homeobox genes, a genetic analysis is mandatory. We generated gain-of-function mutants by introducing genomic sequences of the Hox-1.1 gene under the control of a chicken beta-actin promoter into mice. Our previous data had shown that these transgenic mice are nonviable after birth and are born with craniofacial abnormalities. In a subsequent detailed analysis of severely affected animals, malformations of the basioccipital bone, the atlas, and the axis were observed. Manifestation of an additional vertebra, a proatlas, occurred at the craniocervical transition. The dominant interference of the Hox-1.1 transgene with developmental programs seems to occur around day 9 of gestation, the time of neural crest migration and somite differentiation. We discuss the resulting phenotype with respect to a developmental control function of Hox-1.1. [less ▲]

Villin, a calcium-regulated actin-binding protein, modulates the structure and assembly of actin filaments in vitro. It is organized into three domains, the first two of which are homologous. Villin is mainly produced in epithelial cells that develop a brush border and which are responsible for nutrient uptake. Expression of the villin structural gene is precisely regulated during mouse embryogenesis and is restricted in adults, to certain epithelia of the gastrointestinal and urogenital tracts. The function of villin has been assessed by transfecting CV1 cells with a human cDNA encoding wild-type villin or mutant villin. Synthesis of large amounts of villin in cells which do not normally produce this protein induces the growth of microvilli on the cell surface and the redistribution of F-actin, concomitant with the disappearance of stress fibers. The complete villin sequence is required for the morphogenic effect. These results suggest that villin plays a key role in the morphogenesis of microvilli. [less ▲]

Transgenic mice which expressed SV40 large T-antigen under the control of the MSV enhancer and the SV40 promoter were generated. In animals containing an intact MSV enhancer, total lens cataracts and neuroectodermal brain tumors, originating in the pineal organ were observed. In contrast, 5' deletion of the MSV enhancer to a residual 53 bp resulted in a different spectrum of pathologies. Whilst lens cataracts still occurred, no brain tumors could be detected. Instead, fibrosarcomas and adenocarcinomas of the kidneys were induced. In addition, tumors of the endocrine pancreas were observed with both transgene constructs. We conclude that the MSV enhancer element is sufficient to direct the expression of the viral reporter gene to the lens and the pineal organ in transgenic mice. Deletion of the MSV enhancer correlates with the loss of DNA elements responsible for the pineal cell specific expression of SV40 large T-antigen. [less ▲]

Neuropeptides, among which substance P, VIP (Vasoactive intestinal peptide), somatostatin, neurotensin, dynorphin and enkephalins, are able to modulate inflammatory processes. Increasing interest is now devoted to these peptides in different inflammatory diseases, concerning skin, lung and joins. The effect of substance P can be dependent on its C-terminal moiety implicating by this way an interaction with specific neurokinin receptors or can be dependent on its N-terminal moiety which does not involve a specific membrane receptor. Such diversity of the action mechanisms of peptides should influence the evolution of the anti-inflammatory therapeutic. [less ▲]

During development, positional values have to be assigned to groups of cells. The murine Hox genes are a class of genes that are predicted to be involved at some stage in this process. During embryogenesis they are expressed in distinct overlapping region- and stage-specific patterns and therefore must be regulated in response to positional information. In this study, we have analysed the activity of Hox1.1 promoter sequences in transgenic mice. The use of lacZ as a marker allows a detailed analysis of expression at the single cell level during early embryonic development. We show that 3.6 kbp of promoter and 1.7 kbp of 3' sequences provide sufficient regulatory information to express a transgene in a spatial and temporal manner indistinguishable from the endogenous Hox1.1 gene during the period of development when Hox1.1 expression is established. The activation occurs in a strict order in specific ectodermal and mesodermal domains. Within each of these domains the transgene is activated over a period of four hours apparently randomly in single cells. In a following second period, Hox1.1 and transgene expression patterns diverge. In this period, transgene expression persists in many mesodermally derived cells that do not express Hox1.1 indicating the absence of a negative regulatory element in the transgene. The anterior boundary of transgene expression is identical to that of Hox1.1. However, no posterior boundary of transgene expression is set, suggesting that a separate element absent from the transgene specifies this boundary. [less ▲]

Capsaicin (10(-9) to 10(-5) M) contracted guinea-pig tracheal strips. Epithelium-containing tracheal strips developed a maximum active tension which was significantly higher than that observed in epithelium-free strips. Anti-CGRP (calcitonin gene-related peptide) serum blocked the epithelium-dependent potentiation of the capsaicin-induced contraction in the intact tracheal strips, without affecting the response of the epithelium-free strips. This result suggests the occurrence of an epithelium-dependent release of CGRP. This same serum markedly reduced the contraction induced by exogenous rat CGRP in both intact and epithelium-free tracheal strips. In epithelium-free tracheal strips, capsaicin-induced contraction was abolished by spantide (10(-6) and 10(-5) M), a substance P antagonist, but, in intact tracheal strips, spantide did not abolish the capsaicin-induced contraction, showing that both CGRP and substance P release are directly induced by capsaicin. Moreover, the contractile responses to rat CGRP of intact tracheal strips from guinea pig suggest that CGRP itself might be able to release a contracting factor from the airway epithelium. Therefore, CGRP originating from the airway epithelium may play a major role in the control of airway smooth muscle tone. [less ▲]

Thirty type 1 (insulin dependent) diabetic children were treated from diagnosis onwards in a random order (using a table of random permutations) with either continous subcutaneous insulin infusion pump therapy (CSII), or with conventional injection therapy (CT). After two years of therapy psychosocial measurements were obtained of fifteen CSII children (8 boys, 7 girls; mean age: 12+/-4 years) and thirteen CT children (6 boys, 7 girls; mean age: 10+/-4 years) and their parents. Two families of the CT group refused to participate. The examination consisted of six tests (for the children: junior dutch personality test, WISC-R intelligence test, family relation test, diabetes questionnaire; for the parents: family interaction scale and assessment of acceptance scale). Parents (and pediatricians) rated CSII children higher on compliance and better on metabolic control. Acceptance of diabetes, physical and psychological condition was rated equally by parents and doctors. Except for the diabetes questionnaire, the children of the two groups scored not significantly different. The CSII group expressed significantly less physical complaints and physical restrictions. CSII children showed a tendency to score higher on recalcitrance compared with CT children. How adequate this coping of CSII children may be, is discussed. [less ▲]

STUDY OBJECTIVE: The aim was to assess the value of baroreflex sensitivity estimates calculated from analyses of spontaneous systolic blood pressure and pulse interval sequences derived from continuous non-invasive finger blood pressure recordings during sitting and active standing. DESIGN: Continuous recordings of digital systolic blood pressure and pulse interval were obtained non-invasively using a Finapres FD5 during 5 min trials of sitting and standing. SUBJECTS: Subjects were healthy males aged 19-28, divided into those with "high" normal (n = 18) and "low" normal (n = 17) blood pressure. MEASUREMENTS AND MAIN RESULTS: Recordings were scanned for spontaneous sequences of three or more cardiac cycles over which systolic blood pressure increased progressively in conjunction with prolonged pulse interval, or decreased while pulse interval became shorter. Regressions between blood pressure and pulse interval (r greater than 0.80) provided estimates of cardiac baroreceptor reflex control. Computations were carried out with concurrent blood pressure and pulse interval measurements, and with a delay or lag of one and two cycles between the two variables. Pulse interval was reduced from an average 870.3 ms sitting to 571.3 ms on standing. Mean baroreflex sensitivity while sitting averaged 17.5 ms.mm Hg-1 at a delay of one cycle, failing to 7.65 ms.mm Hg-1 with standing. The decrease in sensitivity was correlated with the change in pulse interval between trials. The number of sequences was also significantly reduced with standing as opposed to sitting. Three cycle sequences were most frequent, with a lesser number of sequences involving 4, 5, and 6 or more cycles. No significant differences between "high" and "low" normal blood pressure groups were observed. CONCLUSIONS: The analysis of spontaneous sequences from non-invasive recordings may provide useful information concerning cardiac baroreflex control in different postural and behavioural states. A lag of one cycle between systolic blood pressure and pulse interval may provide the most representative estimates of baroreflex sensitivity. [less ▲]

Then his doubts about the possibility of implementing a standardized language analysis in this context are considered. He justifies these doubts by pointing to the interindividual differences in the use of words describing emotions.

We have analysed various adult organs and different developmental stages of mouse embryos for the presence of octamer-binding proteins. A variety of new octamer-binding proteins were identified in addition to the previously described Oct1 and Oct2. Oct1 is ubiquitously present in murine tissues, in agreement with cell culture data. Although Oct2 has been described as a B-cell-specific protein, similar complexes were also found with extracts from brain, kidney, embryo and sperm. In embryo and brain at least two other proteins, Oct3 and Oct7, are present. A new microextraction procedure allowed the detection of two maternally expressed octamer-binding proteins, Oct4 and Oct5. Both proteins are present in unfertilized oocytes and embryonic stem cells, the latter containing an additional protein, Oct6. Whereas Oct4 was not found in sperm or testis, it is expressed in male and female primordial germ cells. Therefore Oct4 expression is specific for the female germline at later stages of germ cell development. Our results indicate that a family of octamer-binding proteins is present during mouse development and is differentially expressed during early embryogenesis. Protease clipping experiments of Oct4 and Oct1 suggest that both proteins contain similar DNA-binding domains. [less ▲]

The role of atrial natriuretic peptide (ANP) in the pathogenesis of essential hypertension has not yet entirely been clarified. We investigated whether the increase of ANP in essential hypertension may be explained by elevated right atrial pressures and/or a different relationship between right atrial pressures and ANP secretion. Patients with stable essential hypertension undergoing right and left heart catheterization because of suspected coronary heart disease had significantly higher ANP levels than normotensives: 58.7 +/- 6.7 pg/ml in hypertensives versus 42.0 +/- 4.1 pg/ml in normotensives (p less than 0.01). Matching hypertensives with normotensives at identical levels of left ventricular enddiastolic pressure revealed significantly higher mean pulmonary artery pressures in hypertensives. Right atrial diastolic pressure (v-wave) after matching for LVEDP was 4.8 +/- 0.5 mm Hg in hypertensives and 3.1 +/- 0.2 mm Hg in normotensives (p less than 0.05). In addition, at any given mean right atrial pressure hypertensives showed higher ANP levels than normotensives. These results demonstrate that hypertensives exhibit raised pressures in the pulmonary artery independent of left ventricular pressure load. The elevation in right atrial pressures and the steeper relationship between these pressures and ANP are a suitable explanation for raised ANP levels in hypertension. ANP in essential hypertension may represent a counterregulation against elevated pulmonary resistance. [less ▲]

Oct4 and Oct5 are two mouse maternally expressed proteins binding to the octamer motif. Both are found in unfertilized oocytes and embryonic stem cells, whereas Oct4 is also found in primordial germ cells. In this study, the activity of the octamer motif was analysed in two embryonic stem cell lines containing Oct4 and Oct5, the teratocarcinoma-derived cell line F9 and the blastocyst-derived cell line D3. It is known that oligomerization of the octamer motif creates a powerful B-cell specific enhancer. As shown here, this oligomerized transcriptional element is also a very strong enhancer in F9 and D3 embryonic stem cells. After differentiation of the stem cells, both enhancer activity and the amount of the octamer binding proteins decrease. An intact octamer stimulates heterologous promoters in embryonic stem cells, whereas mutations in the octamer motif abolish transcriptional stimulation and binding of the octamer factors. The use of transgenic embryos demonstrates transcriptional activation in the inner cell mass but not in the trophoblast of blastocysts. The results indicate that Oct4 and Oct5 are active early in mouse development. [less ▲]

Relaxation delay is an important feature of hypertensive heart disease which impairs diastolic coronary flow and ventricular filling and therefore contributes to heart failure. We investigated the hypothesis that impaired relaxation is a property of the myocardium, rather than the consequence of ischaemia or interstitial fibrosis. A new videomicroscope system was used to define the contraction-relaxation cycle of isolated cardiac myocytes from spontaneously hypertensive rats (SHR) and normotensive control (Wistar-Kyoto, WKY) rats. The SHR cells showed a marked relaxation delay. Angiotensin II (Ang II) increased the contraction maximum by about 35% in WKY rats and induced a relaxation delay. In SHR Ang II greatly potentiated this relaxation delay. Our results demonstrate that impairment of relaxation is a property of the single cardiomyocyte. Angiotensin II induces a relaxation delay that is independent of blood pressure. The combination of hypertrophy and high levels of Ang II potentiates relaxation impairment and may therefore contribute to hypertensive left ventricular failure. [less ▲]

Hox-1.1 is a murine homeobox-containing gene expressed in a time- and cell-specific manner during embryogenesis. We have generated transgenic mice that ectopically express Hox-1.1 from the chicken beta-actin promoter. In these mice Hox-1.1 expression was changed to an almost ubiquitous pattern. Ectopic expression of Hox-1.1 leads to death of the transgenic animals shortly after birth and is associated with multiple craniofacial anomalies, such as cleft palate, open eyes at birth, and nonfused pinnae. This phenotype is similar to the effects seen after systemic administration of retinoic acid during gestation. This suggests that retinoic acid embryopathy and the specific developmental defects caused by ectopic expression of a potential developmental control gene share a common pathogenic mechanism.

Two laboratory studies were carried out to assess the behavior of the active palmar sweat glands in both an active and a passive coping situation. Stressor in study I was watching a distressing film, in study II mental arithmetic. Subjects were male students, 17 in experiment I, 20 in experiment II. Both experiments involved a 10-minute baseline phase, a 10-minute stress period, and a follow-up of 10 minutes. PSI was assessed at 90-sec intervals and averaged across phases, as were readings in SCL, SCR, heart rate, diastolic and systolic blood pressure. PSI could be determined in 16 subjects of each study. In both experiments PSI increased significantly from baseline to stress (p less than 0.1%) and decreased from stress to follow-up (p less than 0.1%), and thus proved to be the most sensitive indicator for stress. The interrater reliability for counting the number of active sweat glands was high when the area for evaluation was defined unambiguously. Since the assessment of the PSI does not require a sophisticated technology and is thus also applicable in field research, we suggest giving more consideration to this variable. [less ▲]

The effects of nedrocromil sodium and disodium cromoglycate were studied on the anaphylactic contraction of guinea-pig trachea in two models of active sensitization (IgE and IgG models). The influence of epithelial removal on the effects of nedocromil sodium and disodium cromoglycate was examined because several studies have shown that the epithelial layer can modulate agonist- or antigen-induced contractile responses. Disodium cromoglycate (10(-4) M) and nedocromil sodium (10(-4) M) provided significant protection against antigen-induced contractions of guinea-pig tracheal smooth muscle in the IgG model. But only nedocromil sodium had an effect at this concentration in the IgG model and was also effective at 10(-5) M in the epithelium-denuded tracheal strips. At this concentration, disodium cromoglycate lost its protective effect. Comparison with the results obtained with FPL-55712, AA-861 and mepyramine suggested that these drugs affect histamine and particularly leukotriene synthesis and/or release by mast cells or other immunocompetent cells. These findings indicate that nedocromil sodium inhibits the IgE- and IgG-related antigen-induced contraction in guinea-pig airways, whereas disodium cromoglycate inhibits only the IgG-related processes. This study supports the hypothesis that these drugs modulate antigen-induced mediator synthesis and/or release from immunocompetent cells. [less ▲]

Incubation of rat peritoneal mast cells with substance P resulted in the transient stimulation of phosphoinositol breakdown and histamine secretion through an exocytotic process. These effects were inhibited markedly by a prior 2-hr exposure of the cells to pertussis toxin. Pertussis toxin also inhibited exocytosis induced by substance P, mastoparan and compound 48/80, but did not modify the secretory effect of the ionophore A23187. The transfer of rat peritoneal mast cells from balanced salt solution to calcium-free buffer led to a similar time-dependent decrease in their response to substance P and mastoparan. The concomitant absence of potassium from the calcium-free buffer enabled the mast cells to retain their secretory response. These data demonstrate identical dependency for calcium and monovalent ions of the secretory process elicited by substance P, mastoparan and compound 48/80. Pretreatment of mast cells with neuraminidase decreased the secretagogic effect of substance P, mastoparan and compound 48/80 without modifying the efficiency of the ionophore A23187. Thus, sialic acid residues might be involved in the initial binding of peptides and compound 48/80 to mast cells, which activate a pertussis toxin-sensitive G-protein and allows the increase in phospholipase C activity to induce exocytosis. This sequence of events might characterize the physiological pathway of mast cell activation by peptides, without necessarily requiring selective membrane receptors. [less ▲]

The function of villin, an actin-binding protein, has been investigated by transfecting fibroblasts with cloned human cDNAs encoding wild-type villin or functional villin domains. Synthesis of large amounts of villin induced the growth of numerous long microvilli on cell surfaces together with the redistribution of F-actin. These microvilli contained a cytoskeleton of F-actin, and their appearance was frequently accompanied by the disappearance of stress fibers. The complete villin gene sequence was required to exert its morphogenic effect. Villin lacking one actin-binding domain (113 amino acids), located at its carboxyterminal end, did not induce growth if microvilli or stress fiber disruption. Our results indicate that villin plays a key role in vivo in the morphogenesis of microvilli. [less ▲]

Isolated calcium-tolerant rat ventricular cardiomyocytes were used to characterize the effects of atrial natriuretic peptide (ANP), Angiotensin II (AII) and their interaction on the myocardial contraction-/relaxation pattern free of interference from other types of cardiac cells. Binding of 125I-ANP showed a KD of 12 pM and approximately 600 binding sites per cell. At 37 degrees C (rate 140 bpm) ANP decreased the contraction maximum with an EC50 of about 70 pM, maximal decrease was 35%. ANP (10(-7) M) raised cellular cyclic-GMP from 0.76+/-0.12 to 1.32+/-0.13 pmole/10(6) cells (73%, p less than 0.05). Angiotensin II increased contractility by a maximum of 32% at 10(-7) M; the EC50 was 8 x 10(-10) M. AII markedly delayed relaxation (reduction of maximum relaxation velocity from 0.092 to 0.063 mm/s; p less than 0.05). ANP (10(-7) M) increased the effect of AII (10(-8) M) on contractility by 66% without changing relaxation parameters significantly. This unexpected interaction may be relevant in pathological conditions where both AII and ANP are stimulated, such as heart failure or secondary hypertension. [less ▲]

Information on clinical and subclinical peripheral neuropathy in children with end-stage renal failure (ESRF) is scarce. We have studied the presence of clinical and subclinical peripheral neuropathy in children with ESRF comparing recently developed non-invasive methods with the measurement of nerve conduction velocities. Twelve children (7 boys, 5 girls; age range: 5-17 years; duration of haemodialysis: 0.5-60 months) participated. Thermal discrimination threshold (TDT) and vibration perception threshold (VPT) were determined twice before and after haemodialysis in each patient. Peroneal nerve conduction velocity was determined once before haemodialysis. No clinical or subclinical peripheral neuropathy was observed in any of the children. Except for two slightly increased TDT values after haemodialysis all results were within the normal range. No correlation was found with age or duration of haemodialysis and no association was found between the three methods. VPT values showed a significant improvement after haemodialysis treatment, although all VPT values were in the normal range. This suggests that haemodialysis has an influence on cutaneous sensation, but further study is needed to confirm this observation. Longitudinal investigations will be necessary to evaluate whether TDT and VPT determinations can be used for early screening of clinical and subclinical neuropathy in children with ESRF. © 1989 IPNA.

Zinc finger proteins (Zfp) are encoded by a large family of genes present in many organisms including yeast and human. Some of them are transcriptional activators and bind specifically to DNA by zinc mediated folded structures commonly known as zinc fingers. The Drosophila Kruppel (Kr) is a segmentation gene and encodes a zinc finger protein. Using a probe from the finger domain of Kr, we have isolated a structurally related gene Zfp-1 from the mouse. In this paper, we report the complete nucleotide sequence of two cDNA clones and the amino acid sequence deduced from them. The putative Zfp-1 protein contains in addition to 7 zinc fingers, two helix-turn-helix motifs. During murine embryogenesis, the Zfp-1 was found to express at a peak level in day 12 embryos. The ubiquitously expressed Zfp-1 gene is located in the 16q region on mouse chromosome 8, between the uvomorulin and the tyrosine amino transferase genes. [less ▲]

Substance P, neurokinin A, neurokinin B, and N-acylated pentapeptide X-Phe-Phe-Gly-Leu-Met-NH2 analogs of substance P7-11 were tested for their spasmogenic activities in intact or in epithelium-denuded tracheal strips from guinea pig. Epithelium removal enhanced the efficacies and potencies relative to substance P of all the peptides tested in guinea pig trachea. In epithelium-containing preparations, the presence of a cyclic substituent (o-hydroxyphenyl-acetyl, p-hydroxyphenyl-acetyl, pyroglutamyl) in Phe7 greatly enhanced the potency and efficacy compared to substance P. These substitutions were twice as active as neurokinin A itself. The presence of an aliphatic chain (non-protected and t-butyloxycarbonyl-protected aminopropyl and aminocaproyl) in Phe7 also improved the potency and the efficacy of the synthetic peptides. The aliphatic substituents could favour an increase in local concentration of the peptides in the vicinity of the receptor(s) allowing a more effective ligand-receptor interaction. Thus, lipophilicity could be determinant in the potency of the peptides in intact guinea pig trachea. In epithelium-denuded tracheal strips from guinea pig, all the synthetic peptides were more effective than substance P but less active than neurokinin A which probably reflects the presence of the NK2 receptor subtype, which may be predominant in this type of epithelium-denuded preparation. Our results suggest that hydrophobicity plays a strong role in the interaction of the peptides, namely substance P and its analogues with the membrane and possibly the receptors themselves. [less ▲]

Uses the example of K. R. Scherer's component process model to critically discuss the theoretical and epistemological problems in cognitive approaches to the analysis of specific emotions. First, a syndromatic understanding of emotions is discussed in which expressive and physiological patterns of reactions as well as perceptions are regarded as necessary components of a specific emotion. Then three of the goals of cognitive approaches named by Scherer are discussed: (1) the scientific conceptualization of specific emotions, (2) the analysis of the semantics of emotion terms, and (3) the causal analysis of specific emotions. In contrast to Scherer's concept, an explicit analysis of natural-language emotion terms is considered to be an essential basis for the scientific conceptualization of specific emotions. The latter is seen as a requirement for differntiating between empirical and pseudoempirical research. [less ▲]

In this study plasma levels of atrial natriuretic peptide and of the catecholamines epinephrine and norepinephrine were investigated in hypertensive patients (HT) (n = 30). 22 normotensive patients (NT) served as controls. Hypertensives showed an elevated ANP-level in comparison with controls (46.8 +/- 3.3 vs. 36.8 +/- 3.3 pg/ml, M +/- SEM, p less than 0.01). When patients with myocardial infarction or with reduced ejection fraction were excluded, the same relation was demonstrated (49.3 +/- 3.2 vs. 33.6 +/- 2.0 pg/ml, p less than 0.01). Plasma norepinephrine was 230.8 +/- 52.3 pg/ml in HT compared with 138.0 +/- 19.6 pg/ml in NT (p less than 0.05). Epinephrine was 70.8 +/- 10.5 vs. 54.8 +/- 9.7 pg/ml in HT and NT. To exclude an increased left ventricular enddiastolic - and hence left atrial - pressure as the cause for the elevation of ANP and norepinephrine, HT and NT were matched for the same levels of enddiastolic pressure (LVEDP) (n = 18). For each level of LVEDP ANP was higher in HT than in NT (p less than 0.01). The same held true for norepinephrine (p less than 0.05) and to a lesser extent for epinephrine (p = 0.09). Our results demonstrate that patients with essential hypertension exhibit markedly elevated levels for ANP and catecholamines which is not due to myocardial failure. We propose that the increased secretion of the vasodilatory hormone ANP serves as counterregulation against the vasoconstrictor norepinephrine. The endocrine function of the heart may play a pivotal role in the modulation of sympathetic activity. [less ▲]

In the present study the prognostic value of ANP measurement was investigated in 52 patients undergoing coronary angiography. 22 normotensive and 30 hypertensive subjects were included. A significant inverse correlation between left ventricular ejection fraction (EF) and plasma ANP was found in normotensives, but not in hypertensives. In patients with chronic myocardial infarction, there was no difference in ANP levels compared to patients without infarction in either group, provided that EF was normal. However, hypertensives showed a 35% increase in ANP compared to normotensives. This was true for subjects with and without myocardial infarction. These results show that in normotensives ANP levels have a prognostic value on a statistical rather than an individual basis. This does not apply to hypertensives, whose ANP level is increased by factors other than impaired ejection fraction. [less ▲]

Auf der Basis einer kognitionspsychologischen Analyse verschiedener aggressionsbezogener Gefühle (Wut, Ärger, Hass, Neid, Empörung) werden bei Wehrpflichtigen Bedingungen der Entstehung und Dämpfung von Feindseligkeit im Sinne von Hass gegenüber einem Vorgesetzten untersucht. Drei Indikatoren der Feindseligkeit wurden erhoben: (1) positive Gefühle bei einer Schädigung des Vorgesetzten, (2) Häufigkeit unwillkürlich interferierender Schädigungsvorstellungen und (3) negative Bewertung des Vorgesetzten. Feindseligkeit wurde im Wesentlichen als Funktion von fünf Variablen erwartet: (1) erlebte Beeinträchtigung durch den Vorgesetzten, (2) wahrgenommene Absichtlichkeit der Beeinträchtigung, (3) wahrgenommene Machtlosigkeit gegenüber dem Vorgesetzten, (4) Ablehnung von Rechtfertigungsgründen für das Handeln des Vorgesetzten und (5) Widerstandswille gegenüber diesem. Dämpfende Effekte auf Feindseligkeit sollten erlebte Sicherheit in sozialen Kontexten haben (Selbstvertrauen, wahrgenommene Unterstützung durch Kameraden oder höhere Vorgesetzte, Gerechtigkeit in der eigenen Einheit) sowie positive Bewertung der Bundeswehr und der Wehrpflicht. Alle Variablen wurden mit eigens konstruierten Fragebogen an einer Untersuchungsstichprobe von 426 Soldaten aus fünf Ausbildungsquartalen und unterschiedlich "harten" Einheiten erhoben. Wesentliche Ergebnisse waren: Die Kernvariablen wirkten in erwarteter Richtung auf Feindseligkeit. Die Indikatoren für erlebte Sicherheit wirkten insgesamt erwartungsgemäß dämpfend auf Feindseligkeit, was die direkten linearen Effekte anbelangt. Die Moderatoreffekte von Sicherheitsvariablen auf die Beziehung zwischen erlebter Beeinträchtigung und Feindseligkeit waren größtenteils erwartungswidrig: je höher die Sicherheit, um so grösser die Effekte erlebter Beeinträchtigung auf Feindseligkeit. Die Validität der Feindseligkeitsmaße wird diskutiert, und praktische Schlussfolgerungen, die die Vermeidung oder Dämpfung von Feindseligkeit betreffen, werden gezogen. [less ▲]

A mouse gene, Cdx-1, was isolated from an embryonic cDNA library using a Drosophila caudal gene probe. The deduced amino acid sequence of Cdx-1 contains conserved sequence domains along the entire gene, as well as a highly conserved caudal-type homeo box. A structural comparison suggests a common ancestral origin of mouse Cdx-1 and Drosophila caudal. The expression of Cdx-1 during embryogenesis was analyzed by Northern blotting and in situ hybridization. Cdx-1-specific transcripts are localized in the epithelial lining of the intestines beginning at 14 days' gestation. The expression of Cdx-1 in the intestine continues into adulthood, but cannot be detected in any other tissues. The Cdx-1 gene is the first homeo-box-containing gene expressed in cells derived from the embryonic endoderm. [less ▲]

Increasing research into the remission phase of type I diabetes mellitus stresses the importance of a non-traumatic and reliable method for the evaluation of endogenous insulin production. We compared 24-h urinary C-peptide excretion (UCE) with plasma C-peptide values before and after stimulation with 1 mg glucagon in 24 type I diabetic children. Fasting plasma C-peptide values and stimulated plasma C-peptide values showed a linear correlation with 24 h UCE. Mean plasma C-peptide levels correlated inversely with the exogenous insulin dose. A slightly better correlation was found between the exogenous insulin dose and 24 h UCE. Control data of 24 h UCE were obtained from healthy siblings. A linear correlation with ages was found up to 10 years of age above which UCE values seem to reach a plateau. This effect of age, as well as the frequency of sampling was taken into account in the derivation of 95% reference intervals for UCE. The measurement of 24 h UCE appears to be a useful parameter to assess endogenous insulin production in diabetic children, provided that age is taken into account. [less ▲]

A decrease in the incidence of Type 1 (insulin-dependent) diabetes mellitus in the age group 0-14 years has been observed from north to south over north-western Europe. To evaluate whether this trend could be found in Luxembourg (a small country between the Netherlands and France) we performed a retrospective study over a period of 10 years. Information concerning all Type 1 diabetic patients (aged 0-19 years at diagnosis), diagnosed between January 1, 1977 and December 31, 1986 was obtained through paediatricians, internists, general practitioners and the Luxembourg Diabetes Association (LDA). The LDA was used as the ascertainment group (to estimate the real number and incidence of Type 1 diabetes mellitus). During the study period 91 Type 1 diabetic patients aged between 0-19 years were diagnosed. An incidence of 11.2 was found in boys (0-19 years). Girls in the same age group showed a considerably lower incidence of 8.8. Standardised incidence (using as standard the world population) revealed an almost similar incidence in the Netherlands and Luxembourg (respectively 10.3 and 10.2) for the age group aged 0-14 years. In France a considerably lower incidence is found (3.6). To what extent different methodology contributes to the differences remains to be clarified. Further prospective studies are necessary to investigate the role of environmental and genetic factors. © 1988 Springer-Verlag. [less ▲]

The present paper is focused on the topic of a structural representation of adjectives describing interpersonal behavior in ordinary Janguage. 40 students of the University of Saarland were presented 117 adjectives selected on the basis of studies in the domain of verbal behavior descriptions by considering the concept of frequency of use. Subjects were asked to partition this set of adjectives into groups under the aspect of similarity of meaning. In order to analyse the relations between the investigated words and to provide a representation of all relevant relations simultaneously, the data of the sorting-task were inspected by hierarchical dustering and multidimensional scaling techniques. Thus a dimensional configuration reflecting inter-dass-relations was obtained and various dustering methods generated concordant dasses of adjectives which appeared to be interpretable at two different Ievels of analysis.

Only the free protein-unbound drug concentration in plasma is pharmacologically active. The concentration of some drugs in saliva is equal to the free drug level. We compared concentrations (in plasma before, 30 and 60 min after the morning dose, in saliva before, 30, 60, 90 and 120 min after the morning dose) of amiodarone (n = 8, 2 x 200 mg orally per day) and flecainide (n = 16, 2 x 100 mg) administered as chronic antiarrhythmic treatment. Drug levels were measured by "high performance liquid chromatography". Results: Just prior to the first morning dose, amiodarone concentrations in plasma were 1.0-2.9 (2.0 +/- 0.6) micrograms/ml, in saliva 0.02-0.25 micrograms/ml; flecainide in plasma 80-560 (316 +/- 163) ng/ml, in saliva 630-3700 (1749 +/- 963) ng/ml. After the morning dose we found maximal flecainide plasma levels of 462 +/- 203 and saliva levels of 3218 +/- 2857 ng/ml. The highest flecainide concentrations in the saliva (13,400 and 11,300 ng/ml) were found in two patients 30 and 60 min after the morning dose. Flecainide, but not amiodarone, is excreted actively in the saliva, probably indicating an enteroenteric circulation. This should be considered to reduce life-threatening flecainide intoxications by gastric and intestinal lavage and suction. The concentration of flecainide in the saliva does not represent the non-protein-bound free drug level in the plasma. [less ▲]

undulated (un) homozygous mice exhibit vertebral malformations along the entire rostro-caudal axis. Pax 1, a murine paired box-containing gene, is expressed in ventral sclerotome cells and later in intervertebral disks along the entire vertebral column. We localized the Pax 1 gene on chromosome 2 between beta 2-microglobulin and the agouti locus to an area where un maps. DNA analysis of the un mutant revealed a point mutation in a highly conserved part of the paired box of Pax 1, leading to a Gly-Ser replacement. The chromosomal location and the mutation in the paired box of un mice in conjunction with Pax 1 gene expression in wild-type mice implicate a causative role of Pax 1 in generation of the vertebral column.

Insulin antibodies were measured in the sera of 28 newly diagnosed diabetic children (age 8.0 ± 4.0 (±SD) years) prior to insulin therapy and after 3, 6, 9, and 12 months. The levels at diagnosis and after 12 months were compared to endogenous insulin production at onset and after 12 to 14 months. Endogenous insulin production was evaluated through the measurement of 24-h urinary C-peptide excretion, fasting plasma C-peptide levels and plasma C-peptide levels after glucagon stimulation. Insulin antibodies were detected in 29% of the patients (8 out of 28). In all but one patient antibodies binding porcine and human insulin were detected. No relationship was found between the presence of antibodies binding human or porcine insulin at diagnosis and age. After 1 year 27 out of 28 patients presented insulin antibodies. No relationship was found between the presence of insulin antibodies before therapy and 1 year after therapy. Insulin antibodies prior to diagnosis showed no relationship with the urinary C-peptide excretion at diagnosis (with antibodies 67 ± 27%, without antibodies 76 ± 11%). However, after 1 year significantly lower urinary C-peptide excretions were found in patients with insulin antibodies prior to therapy (with antibodies, 17 ± 7%, without antibodies, 31 ± 5%, p < 0.02). Peak plasma C-peptide levels after 1 year were possibly lower in patients with insulin antibodies before treatment (with antibodies 0.17 ± 0.06 nmol/l, without antibodies 0.26 ± 0.04 nmol/l, p < 0.1). Fasting C-peptide levels did not differ significantly between the two groups after 1 year of therapy (with antibodies 0.11 ± 0.03 nmol/l, without antibodies 0.14 ± 0.02 nmol/l). Thus, insulin auto-antibodies may be a marker for islet B-cell destruction in Type 1 diabetes. [less ▲]

Antibodies in sera from newly diagnosed insulin-dependent diabetes mellitus (IDDM) patients are directed to a human islet cell protein of relative molecular mass (M(r)) 64,000. Since IDDM seems to develop after a prodromal period of β-cell autoimmunity,, this study has examined whether 64,000 M(r) antibodies could be detected in 14 individuals who subsequently developed IDDM and five first degree relatives who have indications of altered β-cell function. Sera were screened by immunoprecipitation on total detergent lysates of human islets and positive sera retested on membrane protein preparations. Antibodies to the 64,000 M(r) membrane protein were consistently detected in 11/14 IDDM patients, and in all 5 first degree relatives. 10 IDDM patients were already positive in the first samples, obtained 4-91 mo before the clinical onset of IDDM, whereas 1 patient progressed to a high 64,000 M(r) immunoreactivity, at a time where a commencement of a decline in β-cell function was detected. 64,000 M(r) antibodies were detected before islet cell cytoplasmic antibodies (ICCA) in two patients. In the control groups of 21 healthy individuals, 36 patients with diseases of the thyroid and 5 SLE patients, the 64,000 M(r) antibodies were detected in only one individual, who was a healthy sibling to an IDDM patient. These results suggest that antibodies against the M(r) 64,000 human islet protein are an early marker of β-cell autoimmunity and may be useful to predict a later development of IDDM. [less ▲]
