    Alcohol dependence in ICD-9 and DSM-III-R: A comparative polydiagnostic study (1989)

    Notes: Summary Diagnoses of alcohol dependence, using the classification systems ICD-9 and DSM-III-R, were compared in a sample of 215 psychiatric outpatients. A lower diagnostic threshold was obtained for DSM-III-R. This category tended to be more inclusive for relatively mild forms of inadequate alcohol use. Of those patients with ICD-9 alcohol dependence, 79% also met criteria for the corresponding DSM-III-R category, whereas 61% of subjects diagnosed as dependent according to DSM-III-R received the equivalent diagnosis in ICD-9. These results were obtained assuming equal base rates (sample frequencies) for dependence and abuse. Diagnoses were further compared with independently derived scores of the Munich Alcoholism Test (MALT), and the validity of DSM-III-R was found to be superior. Checklist-guided interviews had a positive impact upon accuracy and validity of diagnoses.

    Divergence and convergence of diagnoses for depression between ICD-9 and DSM-III-R (1988)

    ISSN: 1433-8491

    Topics: Medicine
    Notes: Summary Contrasting the classification systems ICD-9 and DSM-III-R, a comparison of diagnoses for unipolar depressive disorders is presented from a sample of 168 psychiatric outpatients. A relatively clear correspondence existed between ICD-9 endogenous depression and DSM-III-R major depression. Neurotic depression (ICD-9) divided into either dysthymia or major depression in DSM-III-R. A generally greater variety of corresponding ICD-9 diagnoses was observed for DSM-III-R categories, since patients with eating disorders, alcohol or drug dependence, or with neuroses other than depressive type often received an additional specific DSM-III-R diagnosis for depression. For ICD-9 diagnostics, a decreased threshold was found for diagnosing depressive reaction, as compared with the equivalent DSM-III-R diagnosis of adjustment disorder with depressed mood. A new technique is introduced in order to adjust corresponding proportions according to base rate differences.

    A five-coordinate copper complex with superoxide dismutase mimetic activity fromStreptomyces antibioticus (1988)

    Notes: Summary A Cu(II) complex of desferrithiocin fromStreptomyces antibioticus was prepared and characterized. The first shell atoms, including one nitrogen and four oxygens, were arranged around the copper in a square-planar pyramide. Due to the axially Jahn-Teller-distorted Cu-O distance at 224.7 pm, a distinct Cu2Zn2superoxide dismutase mimetic activity was measured. The Cu-complex survived 600 μM bovine serum albumin and the thermodynamic stability (pK=17.4) was not very different from that of Cu-EDTA. The electronic absorption properties, circular dichroism and electron paramagnetism were in accordance with those of the type-II copper species.

Complexes of the Type [(C2H5)3NH][O(C6H5)2PM(CO)5] (M=Cr, Mo, W)The air-stable complexes [(C2H5)3NH][O(C6H5)2PM(CO)5] (2) (M=Cr, Mo, W) can be prepared from the chlorophosphane complexes (CO)5MP(C6H5)2Cl (1) or from the diphosphoxane complexes [(CO)5MP(C6H5)2]2O (3) by base hydrolysis with triethylamine. The free phosphinite ligand is not stable. The structures of 2 are elucidated by means of IR, 1H and 31P NMR spectroscopy as well as by an X-ray structure analysis of 2b. A very strong N - H ⃛ O bridging bond is found in 2b.

    Description / Table of Contents: Preparation and Properties of, and Reactions with, Metal-Containing Heterocycles, XLV. Directed Preparation of Ferracyclopropanes and -pentanes as Reactive Intermediates in the Organic SynthesisThe complexes (OC)3LFe(η2-C2H4) (5a - c) and ferracyclopentanes (6ax - cx, 6ay, by, 6az) and ferrahydrindanes , respectively, are obtained by nucleophilic elimination-cycloaddition on the bis-(triflates)Y — [CH2]2 — Y (2), [Y — CH2 — CX2 — ]2 (3x - z) [Y = CF3SO2O; X = H (x), D (y), CH3 (z)] and cyclo-C6H10(CH2 — Y)2 (4) with the bifunctional anions [Fe(CO)3L]2- (1a - c) [L = CO (a), PPh3 (b), P(OMe)3 (c)] in dimethylether and ether, respectively. 5a and 6ax are reactive intermediates in the Fe(CO)5-catalysed olefin carbonylation. 6bx and 5b crystallize from n-butane and n-pentane in the triclinic and monoclinic space group P1 and C2/c with Z = 2 and 8, respectively. In 5b ethene is located equatorially, 6bx has twist-conformation. The thermal decomposition of 6ax and 7a is investigated in the presence and absence of CO. While 6ax behaves indifferent towards liquid SO2, into the Fe — C σ bond, which is in trans-position to the PPh3 ligand, SO2 can be inserted under formation of the cyclic sulfinato-S complex 9.
    Notes: Durch nucleophile Eliminierungs-Cycloaddition an den Bis(triflaten) Y — [CH2]2 — Y (2), [Y — CH2 — CX2 — ]2 (3x - z) [Y = CF3SO2O; X = H (x), D (y), CH3 (z)] und cyclo-C6H10-(CH2 — Y)2 (4) mit den bifunktionellen Anionen [Fe(CO)3L]2- (1a - c) [L = CO (a), PPh3 (b), P(OMe)3 (c)] erhält man in Dimethylether bzw. Ether die Komplexe (OC)3LFe(η2-C2H4) (5a - c) und Ferracyclopentane (6ax - cx, 6ay, by, 6az) bzw. Ferrahydrindane Bei 5a und 6ax handelt es sich um bei der Fe(CO)5-katalysierten Olefin-Carbonylierung auftretende reaktive Zwischenstufen. 6bx und 5b kristallisieren aus n-Butan bzw. n-Pentan in der triklinen bzw. monoklinen Raumgruppe P1 bzw. C2/c mit Z = 2 bzw. 8. In 5b ist Ethen äquatorial angeordnet, 6bx weist Twist-Konformation auf. Der thermische Abbau von 6ax und 7a bei An- und Abwesenheit von CO wird untersucht. Während sich 6ax gegenüber flüssigem SO2 indifferent verhält, läßt sich in die zum PPh3-Liganden trans-ständige Fe — C-σ-Bindung SO2 einschieben unter Bildung des cyclischen Sulfinato-S-Komplexes 9.

    Description / Table of Contents: Preparation and Properties of, and Reactions with, Metal-Containing Heterocycles, XLII The P = S Group as a Building Block in the Heteroanalogous Alkyne CyclocotrimerizationThe S isomeric complexes LnFe(CO)(I) - SPHR½ (3 a - e) [R1 = CH3 (a), C2H5 (b), n-C3H7, (c) t-C4H9 (d), c-C6H11 (e)] are obtained by substitution of CO in LnFe(CO)2I (1) [LnFe = (n-C3F7)-Fe(CO)2] by the phosphane sulfides SPHR1/2 (2a - e). Base supported HI elimination from 3a, b results in the formation of the η2-thiophosphinito complexes (4a, b) which can be regarded as starting points of the P = S heteroanalogues alkyne trimerization. 4b reacts with the electrophilic alkynes 5x - z to give the ferracyclopentadienes (6 bx - z) [R2 = CO2C2H5 (x), CO2CH(CH3)2 (y, CO2C6H11 (z)]. Towards alkynes 6 bx - z behave kinetically labile and are transformed with 5x - z to the bicyclic compounds 7 bx - z under CO separation. According to X-ray structural determinations, 3a, 4 b, und 6 bz crystallize in the monoclinic and triclinic space groups P21/n (3a), C2/c (4b), and P1 (6 bz) with Z = 4, 8, and 2, respectively.
    Notes: Bei der Substitution von CO in LnFe(CO)2I (1) [LnFe = (n-C3F7Fe(CO)2] durch die Phosphansulfide SPHR1/2 (2a - e) [R1 = CH3 (a), C2H5 (b), n-C3H7 (c), t-C4H9 (d), c-C6H11 (e)] erhält man die S-isomeren Komplexe LnFe(CO)(I) - SPHR1/2 (3a - e). Basenunterstützte HI-Eliminierung liefert aus 3a, b die η2-Thiophosphinito-Komplexe (4a, b), welche als Ausgangspunkte der P = S-heteroanalogen Alkintrimerisierung anzusehen sind. Mit den elektrophilen Alkinen 5x - z reagiert 4b zu den Ferracyclopentadienen (6bx - z) [R2 = CO2C2H5 (x), CO2CH(CH3)2 (y), CO2C6H11 (z)]. Diese verhalten sich gegenüber Alkinen kinetisch labil und gehen mit 5x - z unter CO-Abspaltung in die bicyclischen Verbindungen 7 bx - z über. Aufgrund von Röntgenstrukturanalysen kristallisieren 3a, 4 b und 6 bz in den monoklinen bzw. triklinen Raumgruppen P21/n (3 a), C2/c (4b) bzw. P1 (6 bz) mit Z = 4, 8 bzw. 2.
