    Notizen: Abstract In a prospective study elastase α1-proteinase inhibitor (Eα1PI), polymorphonuclear (PMN) count, the immature to total neutrophil count ratio (I/T ratio), and C-reactive protein (CRP) were analysed in 74 patients (76 cases) with neonatal septicaemia at the time of initial clinical symptoms. At that early stage of the disease, 94% of the patients had abnormal values for Eα1PI, 71% for I/T ratio, 61% for PMN count, and only 54% for CRP. PMN count was a poor indicator of septicaemia. Neutropenia, present in 26% of all patients, was related to normal Eα1PI in only 4 patients. The combined use of Eα1 and I/T ratio was the most sensitive indicator. In all patients irrespective of causative bacteria or disease onset at least one of these parameters was elevated. In early-onset septicaemia (n=31), normal CRP values occurred significantly more often (63%) than in late-onset sepsis (33%). Even in five of the seven fatal cases, initial CRP measurements were normal. The sensitivity of PMN count and I/T ratio did not differ significantly between early-and late-onset septicaemia. Laboratory changes observed in 18 newborns during the first 3 days of the septic episode show that the rate of pathological values for Eα1PI and I/T ratio was highest at the time of initial clinical symptoms and decreased on days 2 and 3. In contrast, CRP reached maximal values as late as day 2 (88% abnormal values), followed by a decrease on day 3. We conclude that the use of Eα1PI may improve the laboratory detection of neonatal septicaemia especially if used in combination with I/T ratio.

    Notizen: Abstract A set of phenomenological wave functions has been derived to describe the14N ground state and the isospin triplet consisting of the14C ground state, the first excited state of14N at 2.313 MeV and the14O ground state. Elastic and inelastic electron scattering form factors, the magnetic moment of the14N ground state and the shape factors in theβ ± decay have been employed in a multiparameter fitting procedure to determine the amplitudes of the wave functions inL-S coupling. The inclusion of the beta decay observables in the fit has become possible for the first time since exact formulas for the shape factor in higher order do exist. The set of wave functions deduced exhibit predominately anL=0 contribution for the 0+; 1 states andL=1 and 2 contributions of nearly equal weight for the 1+; 0 state. It was observed that the inclusion of the shape factors allowed a more stringent determination of the amplitudes compared to previous attempts reported in the literature and led in the case of the 0+; 1 states to wave functions that show a small but noticeable difference within the isospin triplet. Besides the observables used for the fit, the radiative widthΓ γ (M1) of the 2.313 MeV state in14N can be described quite well with the derived wave functions, and in addition it has become possible to predict the pathological largeft − value of the14C decay and theft + value of the14O decay precisely. The wave functions are also applied to calculate the14N(γ,π +) cross section.

    Notizen: Heterocyclic Substituted Arenediazonium Salts with a Long-wave-length Range of Sensitivity. II. 4-(1-Heterocycliden-2,3-diaza-prop-2-en-3-yl)-arenediazonium tetrafluoroboratesThe title compounds (3) are obtained by reaction of aromatic bis-diazonium salts with substituted 2-benzylidene-1,3-dithioles and 2-benzylidene-1,3-diselenole, respectively. The maximum of the long wave-length absorption band of 3 varies from 580 nm up to 665 nm depending on the structure of the compound.The quantum yields of the photolysis of the diazonium salts 3 are low (1 · 10-4 to 7 · 10-3). The azo dyes obtained from 3 with usual azo-couplers absorb in a shorter wave-length range than the corresponding diazonium salts themselves (hypso-coupling effect).

Catalyzed by Lewis acids the compound 3d rearranges reversibly into the isomeric 3H,6H-3,6-bis-(p-N,N-dimethylaminophenyl-imino) -1,2-dithiolo[4,3-c]1,2-dithiole (4d). The Dimroth type rearrangement of 3d into 4d occurs also on irradiation.

The compounds 9-11 can be formed from one another. The compounds 10a,b react with nickel chloride to the stable complexes 14a,b. In basic medium 10 gives the salt of 3H,3N-alkylthiocarbamido-1,2-dithiole-4-thiolate 15, which reacts with methyl iodide to 3H,3N-alkylimino-5-N-alkylthiocarbamido-4-methylthio-1,2-dithiole 16.
