    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: 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: Heterocyclic Substituted Arendiazonium Salts with a Long-wave-length Range of Sensitivity  -  Part I: Monomethins and AzamethinsTwo new types of arendiazonium salts have been synthesized. In these compounds a heterocycliden ring is bridged through a methine group (8a-o) or a nitrogen (11a-c) with the 4-position of a benzene diazonium group.Both types show sensitivity towards normal day-light, their long wave-length absorption band vary from 430 nm up to 590 nm, depending on the donor strength of the heterocycliden ring and the nature of the bridging group.The thermostability, the quantum yields of photochemical dediazonation and the coupling behaviour of the diazonium salts are investigated, in order to evaluate their potential applicability in a commercial diazotype system.

    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.

    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: The reaction of 3H,6H-1,2-dithiolo[4,3-c]1,2-dithiole-3, 6-dithione (1) with primary aliphatic amines (8a,b) gives 3H,6H-3,6-bisalkylimino-1,2-dithiolo[4,3-c]1,2- dithiole (9a,b), 3H,3-N-alkylamino-5-N-alkylthiocarbamido-1, 2-dithiolium-4-thiolate (10a,b) and 3H,3-N-alkylimino-4-alkylamino-5-N-alkylthiocarbamido-1,2-dithiole (11a,b). 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.

    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.
