    Notes: Abstract Femoral neck anteversion is the torsion of the femoral head with reference to the distal femur. Conventional methods that use cross-sectional computed tomography (CT), magnetic resonance or ultrasound images to estimate femoral anteversion have met with several problems owing to the complex three-dimensional (3D) structure of the femur. A 3D imaging method has been developed that virtually measures femoral anteversion on the 3D computer space with continuous CT slices; this 3D method provides more accurate and reliable results than conventional 2D CT measurements. A 3D modelling method is devised for the measurement of femoral neck anteversion. This method has advantages over the 3D imaging method, such as shorter processing time, reduced number of slices and an objective result compared with the 3D imaging method. The results of the 3D modelling method are compared with the conventional CT methods (2D CT method and 3D imaging method) using 20 dried femurs.

    Increased serum glutamate in depressed patients (1982)

    Description / Table of Contents: Zusammenfassung Der Serum-Glutamatgehalt wurde bei endogen depressiven, neurotisch depressiven, schizophrenen und schizoaffektiven Patienten sowie gesunden Kontrollpersonen bestimmt. Hierbei zeigte sich, daß die Serumglutamatspiegel bei endogen und neurotisch Depressiven signifikant höher waren als bei den anderen Gruppen. Zwischen schizophrenen und schizoaffektiven Patienten sowie Kontrollen zeigten sich dagegen keine signifikanten Unterschiede. Die weitere Analyse der Daten erbrachte die Hypothese, daß die erhöhten Serum-Glutamat-Konzentrationen bei endogen und neurotisch Depressiven eine Folge der antidepressiven Medikation sind. Diese Ergebnisse werden im Hinblick auf die Wirkung der Antidepressiva auf das Serum-Glutamat bei affektiven Störungen diskutiert.
    Notes: Summary Glutamate concentration was determined in serum from endogenous and neurotic depressive patients, in persons with schizophrenia or schizoaffective disorder, and in normal subjects. The mean serum glutamate level in the endogenous and neurotic depressive patients was found to be significantly higher than in any of the other groups. No other statistically significant differences were found. Statistical analysis revealed that the elevated serum glutamate concentration in the endogenous and neurotic depressive patients was probably caused by medication. These results are discussed in view of the effect of antidepressants upon the serum glutamate in the affective disorders.

    Effects of amitriptyline on serum glutamate and free tryptophan in rats (1982)

    Description / Table of Contents: Zusammenfassung Die chronische Gabe von Amitriptylin (2 Wochen, 10 mg/ kg, i.p.) führte zu einer signifikanten Zunahme von Glutamat und freiem Tryptophan im Serum von Ratten. Dagegen hatte Amitriptylin eine Wirkung weder auf das Gesamttryptophan im Serum noch auf den Glutamatgehalt des Liquors. Diese Ergebnisse bestätigen die Hypothese, daß Antidepressiva für die Zunahme des Serumglutamats bei Depressiven verantwortlich sind.
    Notes: Summary In rats, chronic amitriptyline (14 days, 10 mg/kg, IP) administration resulted in a significant increase in the serum glutamate concentration and concomitant increase in the serum free tryptophan. In contrast, amitriptyline had no effect on the total serum tryptophan or CSF glutamate level. The data confirmed that antidepressant drugs may induce an increase of the serum glutamate concentration in depressive patients.
