    Description / Table of Contents: Resacetophenonoxim-Formaldehyd-Harze erwiesen sich für verschiedene Metallionen als selektiv komplexierende Ionenaustauscherharze. Zur Bestimmung der Selektivität wurde eine Gleichgewichts-batch-Methode angewandt. Die Methode beinhaltet die Messung der Verteilung eines gegebenen Metallions zwischen einer wäßrigen Lösung und dem Harz. Die Untersuchung wurde in einem weiten pH-Bereich und in Medien verschiedener Ionenstärke durchgeführt.
    Notes: Resacetophenoneoxime-formaldehyde resins showed to be selective chelating ion exchange resins for certain metal ions. A batch equilibrium method was used in the study of the selectivity of metal ion uptake. The method involved the measurement of distribution of a given metal ion between an aqueous solution and the resin. The study was carried out over a wide pH range and in media of various ionic strengths.

    Description / Table of Contents: Es werden die Synthese und Eigenschaften eines Resacetophenon (2,4-Dihydroxiacetophenon)-Formaldehyd Harzes beschrieben. Das mittlere Molekulargewicht des Harzes, durch Dampfdruckosmometrie und wasserfreie konduktometrische Titration bestimmt, beträgt 2500 bzw. 2200 g/mol.Von diesem Harz wurden Cu(II)-, Ni(II)- und Co(II)-Chelate hergestellt. Die Elementaranalyse der Chelate ergab ein Verhältnis Metall : Ligand von 1:2. Aus den Reflexionspektren der Chelate konnte geschlossen werden, daß Ni(II)- und Co(II)-Chelate eine tetraedrische Struktur haben, während Cu(II)-Chelate eine quadratisch-ebene Struktur zeigen. Infrarotuntersuchungen zeigen, daß die Metalle über den Sauerstoff der Carbonyl-und Phenolgruppe gebunden sind. Auch die Anwesenheit von Methylenbrücken ist aus den IR-Messungen zu erkennen. Die thermischen Eigenschaften des Harzes und seiner Metallchelate werden diskutiert.
    Notes: Synthesis and properties of a resacetophenone-formaldehyde resin are described. The number average molecular weight of the resin determined by vapour pressure osmometry and nonaqueous conductometric titration is 2500 and 2200 g/mol, respectively.Cu(II), Ni(II) and Co(II) chelates of the resin were prepared. The elemental analysis of chelates indicated a metal to ligand ratio 1:2. From the diffuse reflectance spectra of the chelates it could be concluded that Ni(II) and Co(II) chelates have a tetrahedral structure while Cu(II) chelate has a square planar structure. Infrared spectral studies showed that the metals are co-ordinated through the oxygen of the carbonyl and phenolic groups. The presence of methylene bridges was also indicated from IR spectral studies. The thermal properties of the resin and its metal chelates are discussed.

    Notes: Abstract 99mTc(V)-DMSA kits developed by the Radiopharmaceutical Division, Bhabha Atomic Research Centre, have been evaluated for potential use in scanning medullary carcinoma of the thyroid and its metastases. There were 15 patients with proved medullary carcinoma and 6 patients with other differentiated thyroid carcinoma. Amongst the 15 patients with medullary carcinoma, 12(80%) showed positive localisation either in the primary or one or more metastatic sites. None of the six patients with carcinoma other than medullary showed increased concentration of 99mTc (V)-DMSA. Of the 37 known metastatic sites in 15 patients with medullary carcinoma, 24 showed concentration of 99mTc (V)-DMSA (64.9%). In addition, 99mTc(V)-DMSA concentration was seen in 14 sites where no evidence of metastasis was revealed. The incidence of 99mTc (V)-DMSA concentration in soft tissue and bone metastasis was similar.

    Notes: Abstract Consequent to the promising results reported with 99mTc(V)-DMSA for imaging certain types of soft tissue tumors, we have developed methods to prepare this radiopharmaceutical in three ways:-(i) from freshly prepared reagents, (ii) through the use of a two component kit and (iii) use of the standard renal DMSA kit by a modified recipe. The 99mTc(V)-DMSA complex has been subjected to paper electrophoretic and chromatographic procedures and also biodistribution studies. The distinctly different behaviour of this new product compared to that of the well known renal DMSA complex has been clearly established. Scintiimaging in a preliminary clinical trial in patients with medullary carcinoma of the thyroid has been encouraging.

    Notes: Epoxy Phenolic novolac resins were prepared from the acid catalyzed condensation products of various phenols such as phenol, p-cresol, p-tert-butyl-phenol and cardanol with formaldehyde. All of these resins have been utilized to prepare the glass-reinforced composites. The fabricated composites were evaluated for their mechanical and dielectric properties. The incorporation of an epoxy fortifier yielded a significant improvement in mechanical properties.

    Notes: Polyethers are prepared by condensing, respectively, 2,4-dichloroquinoline and its 6-methyl and 6-methoxy derivatives separately with ethylene, propylene, butylene, diethylene and triethylene glycols. These polyethers are characterized and the electrical conductivity of polyethers is measured at various temperatures up to 150°C.

    Notes: Abstract Sirenomelia, or mermaid syndrome, is the extreme form of caudal regression syndrome. We present another case of this fascinating anomaly with fused lower limbs, absent external genitalia, and absent genitourinary system. The patient could not be salvaged because of bilateral renal agenesis. Detailed autopsy findings and a review of the literature are presented.
