    Notizen: Abstract   Objective: To determine the efficiency of intravenous infusion of octreotide in the treatment of patients with severe pancreatitis and pulmonary failure. Design: Prospective, case–control study. Setting: Intensive care unit of a university hospital. Patients: Treatment group: 39 patients with necrotizing pancreatitis were selected for the study. In all, pulmonary failure developed under conservative treatment and surgical intervention had been necessary because of local (abscess, necrosis) or systemic (systemic inflammatory response syndrome) complications. The outcome was prospectively followed up until death or discharge from the hospital. Control group: 54 case–control matched patients with acute necrotizing pancreatitis and pulmonary failure, who had not been treated with octreotide. Intervention: Each patient in the treatment group received 100 μg intravenous octreotide three times daily for 10 days, in addition to the standard intensive care therapy. Results: The groups (octreotide group, control group) were highly comparable with regard to age (mean age: 54, 51 years), sex, severity of illness (Acute Physiology and Chronic Health Evaluation II score: 27, 27), etiology of pancreatitis, and pretreatment at the time of admission to the intensive care unit. There was no difference in the development of renal, hepatic, gastrointestinal, hemostatic, neurologic, or local complications. But the frequency of the adult respiratory distress syndrome (18 vs 40%; p〈0.05) and circulatory shock (51 vs 87%; p〈0.05) was significantly lower in the treatment group. Furthermore, mortality was 26% (10 of 39 patients) in the octreotide group and 61% (33 of 54 patients) in the control group (p〈0.01). Conclusion: The results of our case–control study showed a beneficial effect of octreotide in patients with severe necrotizing pancreatitis and pulmonary failure. Based on these data, a prospective, double-blind, placebo-controlled study should be performed to evaluate these results.

    Notizen: Synthesis and Oxydation of 1-(1,3-Thiazol-2-yl)-pyrazolidin-3-onesThe 1-(1,3-thiazol-2-yl)-pyrazolid-3-ones 4 are synthesized by reaction of 1-thiocarbamoyl-pyrazolidin-3-one 2 with α-halogenaldehydes and α-halogenketones, respectively. The structure of 4 is proved by their 1H-n.m.r. and mass spectra. Oxydative dimerisation of 4 leads to the bisazomethinimines 10. The compounds 10 represent a new type of azomethinimines with a quinoid structure.

    Notizen: Tetrathiafulvalenes. XXI. Syntheses of Tetrathiafulvalenes from 2-Alkylthio-, 2-Arylthio- and 2-Alkylseleno-1,3-dithiolium SaltsIn the reaction of 2-alkylthio-, 2-arylthio- or 2-alkylseleno-1, 3-dithiolium salts with trivalent phosphorus compounds in acetonitril tetrathiafulvalenes 2 are formed. As an intermediate we suppose a phosphorane, which reacts with further 1,3-dithiolium salt to provide the tetrathiafulvalene. By the application of a 2-alkylthio-1,3-dithiolium salt a monomethin dye is formed in a side reaction. When the reaction is carried out in methanol, the phosphorane is trapped by the solvent and a 2H-1,3-dithiolium salt is obtained.

    Notizen: About Chlorination of N-Aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultamesThe sultames of structure 1 are easily chlorinated by sulfurylchloride, chlorine or tertbutylhypochlorite. The structure of the mono-(2a-c,3a, d), di-(4a-d), tri- (5c, d) and pentachlorosultames (6a, b) is determined by 13C-n.m.r. spectroscopy. Contrary to the bromination the chlorination (by SO2Cl2) starts with the substitution of the sultamring (formation of mono- and di-chlorosultames) followed of the substitution of the (C-4)-CH3- group (formation of trichlorosultames). By 1,4-addition of an other molecule of chlorine to 5 the pentachlorosultames 6a, b are obtained. Already by recrystalisation of 6a, b in an alcohol the chlorine in 4-position is exchanged by the corresponding alkoxy group (CH3O, C2H5O, n-C3H7O) and the compounds 7-9 are formed.

    Notizen: Organic Electron Conductors and Precursors. V. Synthesis of Poly (organylthio-acetylenes)Poly(bis-organylthio-acetylenes) 2 and poly(mono-organylthio-acetylenes) 3 have been synthesized by complex catalyzed polymerization of the corresponding acetylenes (4 resp. 5). Yields and properties of the polymers 2, 3 depend on reaction conditions, the catalyst and the nature of the acetylenes. Relations between these influence factors are discussed.

    Notizen: Iodation of N-Aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultamesBy the iodation of N-aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultames 1 with I2/HgO in EtOH/AcOH the 1,2-thiazine ring is substituted. The monosubstitution occurs on the 1-position (1a, d) and the disubstitution on the 1,3-position (3a). By iodine monochloride in CHCl3 the sultames 1a-d were substituted in the (C-2)-CH3 group (4a-d), in contrast also to the results of chlorination and bromination of 1. The structure of the products 2, 3, 4 was proved by 13C-n.m.r. spectroscopic data.

    Notizen: Synthesis of 2-Heterocyclidenamino-1, 3-diaza-trimethincyaninesThe synthesis of 2-[3-methyl-benzthiazol-(1, 3)-inylidene-(2)-amino]- and of substituted 2-[1, 3-dithiolyliden-(2)-amino]-1, 3-diaza-trimethincyanines is described. The heterocyclic imines 1 react with phosgene or thiophosgene to the corresponding ureas 2 and thiureas 3, respectively. Alkylation of 3 to the 2-alkylmercapto-1, 3-diaza-trimethincyanines 4 and subsequent condensation with imine 1 yields the dyes 5. The chemical and spectroscopical data of cyanines 5 are described.
