    Notes: Summary The effect of low doses of heparin on the binding of phenytoin and prazosin to plasma proteins was evaluated in four normal subjects. Heparin activates the hydrolysis of triglycerides in plasma. The ensuing increase in non-esterified fatty acids (NEFA) was more marked in vitro than in vivo and increased the free fraction (FF) of phenytoin and prazosin in plasma. The higher FF caused a change in the plasma to whole blood ratio (P/B ratio) of both drugs. The changes in FF and P/B ratio after heparin were small, but could be of significance in pharmacokinetic studies.

    Notes: Summary Prescribing patterns were studied in a psychiatric outpatient clinic. Psychiatrists tended to prescribe large quantities of antidepressants or other drugs. In contrast, the daily doses for antidepressants and neuroleptics were often too low. Significant variations were noted between three outpatient clinics in the choices among a various psychotropic drugs from a given therapeutic group.

    Notes: Summary In a companion paper we described the disposition of a 75 mg single dose of amitriptyline in normal volunteers who were phenotyped as extensive or poor metabolizers of debrisoquine and bufuralol, and had a four-fold range in the oral clearance of the antidepressant, 50 mg of amitriptyline was also administered to the same volunteers. This paper compares the results after both doses and suggests that the disposition of amitriptyline is linear even in subjects with a low oral clearance. There was no relation between the pharmacokinetic data and the intensity of sedation or of psychomotor impairment.

    Notes: Summary We have measured the metabolites (demethylated and hydroxylated) of amitriptyline in a group of seven normal volunteers. They were phenotyped as extensive or poor metabolizers using debrisoquine and bufuralol. The results demonstrate that the oxidative metabolism (aliphatic hydroxylation) of amitriptyline is under the same genetic control as that of debrisoquine and bufuralol. However, phenotypic polymorphism cannot be used to predict amitriptyline blood concentration after a single oral dose, since the principal metabolic pathway of amitriptyline is demethylation and not aliphatic hydroxylation.

    Description / Table of Contents: Vibrational Spectra and Force Constants of Symmetric Tops. XXI. Rovibrational Spectrum of CF379Br and CF381Br in the v2 RegionThe rovibrational spectrum of CF379Br and of natural CF3Br has been recorded in the region of the fundamental v2 near 750 cm-1 in the i.r. with a resolution of 0.04 cm-1. From the analysis of the spectra the values of v0, the anharmonicity constants x23, x25 and x26 as well as B″ and B′ from the J structure have been obtained both for CF379Br and CF381Br. v2 displays Fermi resonance with 2v3 which is located near 700 cm-1.
    Notes: Das Schwingungs-Rotations-Spektrum von CF379Br und natürlichem CF3Br wurde im Bereich der Grundschwingung v2 nahe 750 cm-1 im IR mit einer Auflösung von 0,04 cm-1 aufgenommen. Aus der Analyse der Spektren konnten für CF379Br und CF381Br v0, die Anharmonizitätskonstanten x23, x25 und x26 sowie aus der J-Struktur die Werte B″ und B′ ermittelt werden. v2 steht in Fermi-Resonanz mit 2v3 bei ∼700 cm-1.

    Description / Table of Contents: Preparation, Crystal Structure, and Temperature Dependence of the Homogeneity Range of the Phase Ca2-xAs1-xBr1+x and Thermal Behaviour of Ca3AsBr3The phase (Ca2-x□x)(As1-xBr1+x) (yellow, NaCl type lattice, x ≙ degree of substitution) was prepared from “Ca3As2” and CaBr2 in different molar ratios in steel ampoules under argon at 900 and 950°C resp. The lattice constant as a function of the composition, the homogeneity range, and dependence of the bromine rich phase boundary on the temperature were determined. The structure was deduced from single crystal X-ray investigation and density measurements at different compositions.The thermal behaviour of Ca3AsBr3 (colourless, isotypic to Mg3NF3, prepared at 850°C) was studied by annealing samples in molybdenum ampoules under argon in the temperature range 900-1250°C and by differential thermal analysis.From the experimental results a section of the phase diagram Ca3As2-CaBr2 was constructed.
    Notes: (Ca2-x□x)(As1-xBr1+x) (gelb, NaCl-Typ, x ≙ Substitutionsgrad) stellte man aus „Ca3As2“ und CaBr2 (unterschiedliche Molverhältnisse) in Stahlampullen unter Argon bei 900 bzw. 950°C dar. Die Abhängigkeit der Gitterkonstante von der Zusammensetzung, der Homogenitätsbereich und die Temperaturabhängigkeit der bromidreichen Phasengrenze wurden ermittelt. Die Struktur bestimmte man durch die röntgenographische Einkristalluntersuchung und durch Dichtemessungen bei unterschiedlichen Zusammensetzungen.Das thermische Verhalten des Ca3AsBr3 (farblos, Mg3NF3-Typ, dargestellt bei 850°C) untersuchte man durch Erhitzen von Proben in Molybdänampullen unter Argon im Temperaturbereich 900 bis 1250°C und durch differenzthermoanalytische Messungen.Mit den experimentellen Ergebnissen wurde ein Ausschnitt aus dem Zustandsdiagramm Ca3As2-CaBr2 konstruiert.
