    Notes: Summary The neuroendocrine effects (changes in plasma CRF, ACTH and cortisol) of single and multiple (t.d.s. for 2 days) doses of ipsapirone (BAY Q 7821) 5 and 10 mg have been investigated in 6 healthy male volunteers. The study followed a balanced complete block, placebo-controlled and double blind design with two baseline phases (pre and post-treatment). Volunteers were investigated on identical days during 5 successive weeks. The results do not show a specific effect of ipsapirone on the hypothalamic-pituitary-adrenal axis when doses in the range of 5–30 mg per day were given.

    Notes: Abstract Between April 1988 and July 1995, 11 children with a lymphangioma were treated with intralesional OK-432 injection. In 7 patients it was the primary therapy and total shrinkage of the lesion was obtained in 5 of them. Two patients did not respond and the children underwent surgery. Following incomplete surgical removal or recurrence of the lymphangioma, intralesional OK-432 injection was used as secondary therapy in 4 patients. Total regression was observed in 2 cases and marked regression in the 2 others. No serious side-effects except fever lasting for 2–3 days and slight tenderness with swelling of the lymphangioma for 3–4 days after the injection was noted. Local inflammatory reaction did not cause any damage to the overlying skin and did not lead to scar formation. Depending on the size, location, and anatomical relationship to the airway, intralesional injections of the lymphangiomas were performed under general anaesthesia and the children were observed for 24 h. There was no recurrence after follow up periods ranging from 2 months to 7 years. Conclusion Intralesional injection of OK-432 represents an alternative, safe and effective treatment for lymphangiomas. It can be used as the primary therapy, after partial surgical excision, or in recurrent lymphangiomas.

    Notes: Die Oberflächenspannung des Quecksilbers im höchsten Vakuum liegt zwischen dem Anfangswert und dem Endwert der Oberflächenspannung in Luft. Bei Zinn konnte eine Veränderung der Oberflächenspannung mit der Zeit im Vakuum von 5·10-5 mm Hg nicht festgestellt werden. Thallium wies eine Zunahme der Oberflächenspannung mit der Zeit im Vakuum von 10-5 bis 10-4 mm Hg auf. Aus diesen Feststellungen wurde geschlossen, daß dort, wo beim Quecksilber Veränderungen der Oberflächenspannung mit der Zeit vorliegen, die sich einstellenden Oberflächenspannungen sich als Resultierende zwischen den Einflüssen der Anordnung der Metallatome der Oberfläche und der ein- und angelagerten Gasatome ergeben.

    Notes: Abstract The torsional dynamics of the 9-(N-carbazolyl)-anthracene (C9A) molecule is investigated by means of time-independent (1) and time-dependent (2) quantum-mechanical simulations in a diabatic representation. The study includes effects of surface crossing of the brightS 1 state with a dark state. (1) The intensity pattern of theS 0 →S 1 fluorescence excitation spectrum is used to fit an effective one-dimensional Hamiltonian with a single-minimum potential for the dark state together with diabatic couplings to the double well potential of the bright state. (2) Based on this Hamiltonian, first predictions for a pump-probe scheme are made. In the pump process the molecules are excited to theS 1 state followed by competing torsions in the bright state and diabatic curve crossings to the dark state, depending on the pump frequency. Assuming the probe process to be an ionization from the bright state, the interfering effects of the dark state on the dynamics in the bright state can be monitored in a directly time-dependent way on a fs-ps time scale.

    Description / Table of Contents: Mg2IrB2-x, a Magnesium Iridium Boride with a Structure Related to the W2CoB2-TypeThe new compound Mg2IrB2-x with a small homogeneity range determined approximately as 0,2 ≤ x ≤ 0,35 crystallizes monoclinically in the space group C2/m, Z=4 (lattice constants see Inhaltsübersicht). The structure which was solved by single crystal X-ray and powder neutron diffraction methods is related to the W2CoB2-type and contains distorted Mg4Ir2-prisms. The boron atoms are partly disordered. They are situated either inside the prisms forming pairs or with very short Ir-B distances (199 pm) on an elongated prism edge formed by two iridium atoms.
    Notes: Die neue Verbindung Mg2IrB2-x mit einem schmalen Homogenitätsbereich, der näherungsweise zu 0,2 ≤ x ≤ 0,35 bestimmt wurde, kristallisiert monoklin in der Raumgruppe C2/m, Z = 4. Bei x = 0,35 betragen die Gitterkonstanten a = 858,0(1) pm, b = 484,6(1) pm, c = 683,6(1) pm, β = 115°43′(1). Die Struktur, die mit Röntgen-Einkristall- und Pulver-Neutronenbeugungsmethoden bestimmt wurde, leitet sich vom W2CoB2-Typ ab und enthält verzerrte Mg4Ir2-Prismen. Die Boratome sind zum Teil fehlgeordnet. Sie befinden sich entweder innerhalb der Prismen und bilden Paare, oder sie liegen auf einer aufgeweiteten, aus zwei Iridiumatomen bestehenden Prismenkante, wobei sehr kurze Ir-B-Abstände ausgebildet werden (199pm).
