    Notes: Abstract  Background and aim of the study: Treatment for hypertrophic obstructive cardiomyopathy (HOCM) has been reported; however, there has been no report on the characteristics of medication-responsive and -refractory hypertrophic obstructive cardiomyopathy (HOCM). Using the classification of systolic anterior movement (SAM) which has been previously reported, we tried to identify the characteristics and use them to treat HOCM appropriately. Methods: The clinical, echocardiographic, catheterization, and surgical data of 29 hospitalized patients with HOCM during 1980 to 1999 were analyzed retrospectively. We classified SAM in all patients by echocardiography. Ninteen patients improved with medical treatment (medical group), and 10 patients underwent surgical treatment because of ineffectiveness of medication (surgical group). We studied the relation between types of SAM and medical/surgical groups, and examined the relation between types of SAM and the surgical methods. Results: Type I SAM was significantly more frequent in the medical group, while type II SAM was more frequent in the surgical group (p = 0.047). Patients in the surgical group underwent mitral valve replacement (MVR), myectomy, or a combination of MVR and myectomy. Left ventricular outflow gradient (LVOG) of over 100 mmHg was recognized in almost all patients with type II SAM. Conclusions: It was suggested that patients with medication-responsive HOCM tended to have type I SAM and those with refractory HOCM tended to have type II SAM. We consider that in type I SAM, if the position of the papillary muscles changed with medication or myectomy, shift of the chordae and type I SAM were reduced or disappeared. However, in type II SAM, even if the position of the papillary muscles changed, SAM did not disappear because lifting of the mitral leaflets remained. It is therefore suggested that patients with type II SAM should undergo at least MVR.

    Notes: Abstract The gastric pedicle is commonly used for reconstruction following resection of esophageal cancer. However, we recently experienced a case in which two gastric tube ulcers occurred three months postoperatively; one penetrating into the pericardial cavity and the other into the left brachiocephalic vein. To our knowledge, no other such a case has ever been reported and we therefore report and discuss its etiology and management.

    Notes: Abstract Copper ions and chelating agents in water were treated simultaneously by using a packed-bed electrode cell. The cathode packings were graphite particles or graphite felt; the anode packings were platinum-plated titanium pellets, β-PbO2 particles or oxidized lead spheres. The catholyte contained ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), iminodiacetic acid (IDA) or glycine chelate of copper, while the anolyte contained the corresponding chelating agents. The initial concentration of chelating agents was 0.01 M in each experiment. The electrowinning of copper and the removal of chemical oxygen demand (COD) were achieved in the cathodic and the anodic chamber, respectively, under galvanostatic conditions. The COD was determined by the standard KMnO4 method. Of the cathodic packings, the graphite felt gave better results than the graphite particles because of the large surface area of the felt. Of the anodic packings, the platinum-plated titanium pellets and the β-PbO2 particles showed equal suitability for COD removal. In the case of the platinum-plated titanium pellets, the current efficiency for COD removal of EDTA, NTA and IDA was 1.4, 0.7 and 0.32, respectively, in the range 0–12 kC. The removal of COD for EDTA, NTA and IDA under the same conditions was 41, 36 and 25%, respectively. In the lower pH range the electro-oxidation of EDTA proceeded more efficiently.

    Description / Table of Contents: Zusammenfassung Zwei neue chromogene Kronenetherreagenzien, 22-Kosh und 21-Kosh wurden durch Kondensation von Cryptand-22 bzw. -21 mit 2-Hydroxy-5-nitrobenzylbromid synthetisiert. Die Extraktion der Erdalkalimetallionen mit einer Dichlorethanlösung von 22-Kosh oder 21-Kosh wurde untersucht und ihre Extraktionskonstanten wurden bestimmt. Für die Leichtigkeit der Extrahierbarkeit mit den beiden Reagenzien ergibt sich folgende Reihenfolge: Mg《Ba〈Sr〈Ca. Die Extraktion mit 22-Kosh ist wirksamer, die Selektivität für Erdalkalimetallionen mit 21-Kosh jedoch ausgeprägter als mit 22-Kosh. 22-Kosh erwies sich als vielversprechendes Reagens für die photometrische Bestimmung von Calcium in Blutserum. Der molare Extinktionskoeffizient des Calciumkomplexes beträgt 5,5×104 bei 406 nm.
    Notes: Summary Two new chromogenic crown reagents, 22-Kosh and 21-Kosh, have been synthesized by the condensation of Cryptand-22 and -21, respectively, with 2-hydroxy-5-nitrobenzyl bromide. Extraction of alkaline-earth metal ions with a dichloroethane solution of 22-Kosh or 21-Kosh has been investigated and their extraction coefficients have been evaluated. The relative ease of extraction is Mg《Ba〈Sr〈Ca for both reagents. The extraction is more effective with 22-Kosh than with 21-Kosh, and the selectivities for alkaline-earth metal ions are more pronounced with 21-Kosh than 22-Kosh. 22-Kosh is found to be a very promising reagent for the extraction-photometric determination of calcium in blood serum. The molar absorptivity of the calcium complex is 5.5×104 l·mole−1·cm−1 at 406 nm.

    Notes: Abstract The purpose of this study was to examine the clinical results of current circulatory support with step-by evaluation of biventricular and pulmonary function. Six patients who had undergone cardiac surgery and two non-cardiotomy patients underwent current circulatory support with the step-by functional evaluation. Of six postcardiotomy patients, four patients with severe ischemic heart disease underwent coronary artery bypass giafting (CABG), and the remaining two patients with advanced aortic stenosis underwent aortic valve replacement (AVR). All six patients received intra-aortic balloon pump (IABP) support before or during operation. Two non-cardiotomy patients suffered from dilated cardiomyopathy, and both showed acute deterioration with cardiogenic shock or low cardiac output syndrome. Three of six postcardiotomy patients with circulatory support were weaned and discharged from the hospital. Two noncardiotomy patients in critical condition were successfully supported for more than 6 months by the Novacor left ventricular assist system (LVAS). We conclude that the ongoing current strategy of circulatory support with step-by functional evaluation might be applied for various types of severe heart failure with or without associated cardiac operations.

    Notes: Summary Incidences of dystopia canthorum and some other signs were studied in a family with Waardenburg syndrome type I. When “W” index was used as a diagnostic parameter, dystopia canthorum was expressed in 88% of the family members who exhibited one or more of the signs, whereas incidence of this trait was calculated to be 63% or less, when the other indices were employed. Incidences of the other signs ranged from 50% to 13%. These observations indicate that W index is the most sensitive indicator of dystopia canthorum, and that this characteristic is most frequently expressed among the signs of Waardenburg syndrome type I.

    Notes: Reaction of aryliminodimagnesium [ArN(MgBr)2, IDMg] with nitrobenzene (Ar1NO2) in tetrahydrofuran (THF) gives unsymmetrical (unsym) azoxybenzene, which is deoxygenated to give unsym-azobenzene. The reaction is utilized for the independent preparation of ONN and NNO isomers of unsym-azoxy compounds. The effects of the relative value of the difference between oxidation and reduction potentials of para-substituted reactants, special effects of ortho-substituents of the substrate and also effects of structure and concentration of mono- and bis-IDMg reagents were studied previously, and ‘cooperation of their aggregate excess needed for product formation’ was proposed. This unfamiliar concept for reactions of magnesium reagents was studied further. Supporting evidence was obtained from the retarding effect of trimethylene chains of nitro [3.3] metacyclophanes and the derived azoxy [3.3] metacyclophanes and also from the effect of the length of bis-IDMg's central α,ω-polymethylenedioxy chain appropriate for azoxy deoxygenation. By comparison with deoxygenation by X3P reagents (X = EtO, Me2N), the general needs of cooperation of excess magnesium reagents were confirmed and its role in their reactions is discussed.

    Notes: New N-alkylation and N-arylation procedures starting from anilinomagnesium (ArNHMgBr) are reported. For N-alkylation with alkyl bromides, addition of hexamethylphosphoramide to an ArNHMgBr solution in tetrahydrofuran (THF) is effective. After heating at 55°C, N-monoalkylation product was obtained in 60-90% yield, slight dialkylation taking place. The combined use of aryliminodimagnesium [ArN(MgBr)2] with α,ω-dibromoalkanes led to N-arylazacycloalkanes. For N-arylation with iodobenzene, replacement of THF with pyridine and additional use of copper(I) iodide are effective. After heating at 115°C with iodobenzene, mono- and diarylation products were obtained, the former being predominant. The combined use of ArNHMgBr and N,N,N′,N′-tetramethylethylenediamine as the ligand of copper species is effective for elimination of diarylation and other undesired products, and leads to diarylamines in excellent yield. The method is of advantage over the conventional Ullmann and Chapman methods. The polar solvents and copper salt are effective additives for inducing ‘inert combinations’ of ArNHMgBr or ArN(MgBr)2 with alkyl and aryl halides into N—C coupling, to extend the unified view proposed for the reactivity of magnesium reagents. The difference in the roles of N—Mg and N—Cu species is discussed.
