    Notes: Abstract Morphologic investigation of the urethrovesical junction combined with urodynamic findings is necessary to choose the correct surgical procedure for female stress incontinence. This study compares colpourethrocystography and perineal sonography in 41 patients with genuine stress incontinence, 30 patients after Burch colposuspension and 40 healthy control women. The study determined the inclination angle, the pubourethral angle, the posterior vesicourethral angle and as the distance H between the lower pubis and the internal urethral meatus. Introital sonography avoids exposure of the patient to X-irradiation and gives similar findings to urethrocystography. Sonography is a fast, easy to perform, inexpensive and reproducible method which is well accepted to the patient. It may be very important in evaluating the morphologic effect of incontinence surgery instead of urethrocystography.

    Notes: Conclusion Ultrasound is a complementary evaluation for the study of female urinary incontinence which allows functionalmorphological documentation. A reliable urogynecologic examination is based on the patient's history, clinical evaluation, urodynamics and imaging. Training in sonography of the female lower urinary tract should be performed within the scope of urogynecological evaluations.

    Notes: Abstract A new method of clitoroplasty is described that more closely simulates normal clitoral anatomy than previously described methods. The technique has been used successfully over the past 15 years in 37 patients whose underlying conditions were: congenital adrenal hyperplasia (24); mixed gonadal dysgenesis (6); partial androgen insensitivity (5); and exogenous androgen stimulation (2). The key points of this new technique are: (1) minimisation of blood loss; (2) reduction in clitoral girth rather than length; (3) preservation of the vascular and nerve supplies; and (4) creation of a hair-pin bend in the shaft of the clitoris, which simulates normal female anatomy as well as achieving an apparent reduction in length. Irrespective of the cause or severity of the virilisation, all patients obtained a good cosmetic result, 78% being regarded by their parents as appearing like a normal female. Five early patients required further surgery to achieve the desired results. Confident from experience that a good cosmetic result can be achieved without major surgical risk, even in a neonate, we now advocate surgical correction at the earliest possible age: as soon as an accurate diagnosis has been made, the parents have accepted the gender assignment, and the infant's metabolic condition has been stabilised.

    Description / Table of Contents: Summary The divergent composition of the ordinaryp-dimethylaminobenzaldehyde reagent solutions used for the detection and determination of the ergot alkaloids does not always insure that the color reaction will proceed quantitatively. A study was made of the dependence of the reaction on the alkaloid content of the solutions to be measured, on the acid concentration of the reagent, and on the amount of ferric chloride added as oxidizing agent. The influence of light, particularly ultraviolet radiation, was studied with respect to the achievement of maximum extinction values. A reagent solution prescribed expressly for this purpose is suitable for the determination of ergot alkaloids. The generally employed marking of the alkaloid flecks that fluoresce in filtered UV light of the mercury lamp as employed in the chromatographic detection has no influence on the measurements obtained photometrically.
    Abstract: Résumé La composition différente des solutions usuelles dep-diméthylaminobenzaldéhyde utilisée pour l'identification et le dosage des alcaloides de l'ergot de seigle n'assurent pas toujours une évolution quantitative de la réaction colorée. L'auteur a contrôlé la dépendance de la réaction de la teneur en alcaloïdes de la solution à mesurer, de la concentration en acide du réactif et de la quantité de chlorure ferrique introduit comme réactif oxydant; il a étudié d'autre part l'influence de la lumiére en particulier du rayonnement ultraviolet sur l'obtention de valeurs d'extinction maximales. Une composition de réactif indiquée particuliérement à cette fin est appropriée aux dosages photométriques des alcaloïdes de l'ergot de seigle. Le marquage habituellement employé de la tache d'alcaloide fluorescente dans la lumiére ultraviolette filtrée de la lampe à vapeur de mercure, obtenue pour identification par chromatographie sur papier, est sans influence sur les résultats de mesures obtenus par photométrie.
    Notes: Zusammenfassung Die unterschiedliche Zusammensetzung der gebräuchlichen p-Di-methylaminobenzaldehydreagenslösungen zum Nachweis und zur Bestimmung der Mutterkornalkaloide gewährleistet nicht immer einen quantitativen Verlauf der Farbreaktion. Die Abhängigkeit der Reaktion vom Alkaloidgehalt der zu messenden Lösungen, von der Säurekonzentration des Reagens und von der Menge des als Oxydationsmittel zugesetzten Eisen(III)-chlorids wurde überprüft, sowie der Einfluß von Licht, insbesondere von UV-Strahlung auf die Erzielung maximaler Extinktionswerte studiert. Eine eigens hierfür angegebene Reagenslösung ist für photometrische Bestimmungen von Mutterkornalkaloiden geeignet. Die allgemein übliche Markierung der im gefilterten UV-Licht der Quecksilberdampflampe fluoreszierenden Alkaloidflecke beim papierchromatographischen Nachweis ist ohne Einfluß auf die photometrisch zu ermittelnden Meßergebnisse.

    Notes: Abstract Electrical conductivities of Ni2SiO4, Fe2SiO4, and MgSiO3 were measured on synthetic powders in the temperature range 340° to 1,100° C and at pressures up to 20 kbars. For ternary compounds such as olivines and pyroxenes the control of two further variables, like the chemical activities of two components are needed, besides temperature and pressure. The activities of the corresponding binary oxides were controlled by equilibrating the samples with their neighbour-phases. Control of the oxygen partial pressure was achieved by buffer techniques. From the slopes of the lg σ vs. 1/T lines the activation energies were calculated for 10 kbar: 0.56 eV and 2.7 eV for Ni2SiO4 in equilibrium with SiO2 and Ni/NiO-buffer for the temperature range 500°–800°C and 800°–1,000°C resp. 0.52 eV for Fe2SiO4 in equilibrium with SiO2 and metallic iron, and 0.38 eV in equilibrium with SiO2 and magnetite; 1.11 eV for MgSiO3 in equilibrium with SiO2, and 1.25 eV in equilibrium with Mg2SiO4.

    Notes: Zusammenfassung Die Erfassung der Morphologie des Blasenhals-Urethra-Übergangs kann sowohl durch die Kolpourethrozystographie als auch die Introitussonographie erfolgen, wobei der Vorteil der Sonographie in der beliebigen Wiederholbarkeit zu sehen ist, aber auch eine größere Erfahrung in der Einschätzung erfordert.
