Einfluß von oxidierten Ölen/Fetten sowie α‐Tocopherol‐ und Antioxidantienzulagen auf das Wachstum und die Vitamin E‐ und A‐Gehalte in Geweben von Masthühnerküken
Authors: Eschenbach R. , Hartfiel W. 
Published: November 2006

AbstractFettgehalte im Mischfutter für Masthühnerküken lassen einen beschleunigten Fettverderb erwarten, wobei auch mit negativen Folgen auf die fettlöslichen Vitamine E und A gerechnet werden muß. In insgesamt 3 Fütterungsversuchen mit jeweils 20 Gruppen von je 9 Tieren wurden der Futtergrundmischung frisches und oxidiertes Fett (Schmalz, tierisches Mischfett) bzw. Öl (raff. Sojaöl) in einer Menge von 10% zugesetzt. Verschiedene α‐Tocopherolacetat(α‐TA)‐Zulagen (0, 25, 50, 75, 100 mg/kg Futter) sowie verschiedene synthetische Antioxidantien (EMQ, BHT, LOXIDAN‐TD 100) in Kombination mit 25 bzw. 50 mg α‐TA wurden in drei Versuchen Futtermischungen zugesetzt. Die Vitamin E und A‐Bestimmungen im Blut‐Plasma, im Fett des Unterhautfettgewebes und der Leber erfolgten mittels Hochdruckflüssigkeitschromatographie. Durch die oxidierten Felle/Öle wurde der Vitamin A‐Gehalt in den Lebern signifikant erniedrigt. Enthielten die Rationen zusätzlich Antioxidantien, so ergaben sich statistisch gesichert höhere Vitamin A‐Werte in diesem Organ.
Energieeinsparungen bei Dampf‐ und Heißwasseranlagen
Authors: van Praagh B. 
Published: November 2006

AbstractBei Dampf‐ und Heißwasseranlagen läßt sich durch Umstellung von Dreizugkesselsystemen auf moderne Dampferzeugungsverfahren eine Menge Energie sparen. Kessel neuartiger Konstruktionen sind von Größe und Gewicht ‐ bei gleicher Leistung ‐ wesentlich kleiner als Dreizugkessel. Dies bringt eine Einsparung von ca. 5–11% beim Anfahrvorgang. Bei herkömmlichen Kesseln bleibt im Stand‐by‐Verfahren der Stand‐by‐Kessel stets unter Druck und Temperatur, während moderne Kessel im kalten Zustand verharren können, da in 5 Minuten volle Betriebsbereitschaft erreicht wird. Hier lassen sich weitere 5%Brennstoff einsparen. In den unteren Lastbereichen hat ein moderner Wasserrohrkessel wesentlich bessere Wirkungsgrade zu bieten als Großwasserraumkessel. Diese Tatsache bringt, je nach Fahrweise, der Anlage Brennstoffeinsparungen zwischen 8 und 12%. Auch durch leistungsabhängiges automatischen Abschlämmen, durch die Nutzung der Vorteile einer Mehrkesselanlage sowie die Anwendung von geschlossenen und halbgeschlossenen Kondensatsystemen lassen sich nochmals ca. 15% Brennstoff einsparen.
Vitamin E (α‐Tocopherol) als Arzneimittel – eine Bestandsaufnahme
Authors: Blankenhorn G. , Fischer I. 
Published: November 2006

AbstractVitamin E schützt als lipophiles unspezifisches Antioxidans die Membran‐Lipide körpereigener Zellen vor toxischen oxidierenden Radikalen. Während beim gesunden Menschen eine über die tägliche Erhöhung hinausgehende Zufuhr von Vitamin E in der Regel nicht notwendig ist, sind prophylaktische Gaben von ca. 100 mg/Tag bei ungewöhnlicher Belastung sinnvoll und seitens der Verträglichkeit unproblematisch. Bei entzündlich rheumatischen Erkrankungen sind höhere Dosen angezeigt als Schutz vor den chronisch vermehrt auftretenden Sauerstoff‐Radikalen wie Superoxid‐Radikalen (· O2‐) und Hydroxyl‐Radikalen (· HO–) (oxidativer Streß). Trotz der guten Verträglichkeit hoher Dosen Vitamin E sollten Dosierungsempfehlungen und Dauer der Therapie in Anbetracht der Schwere der Erkrankung dem medizinischen Berater vorbehalten sein.

Published: November 2006

AbstractThe present study is an attempt to know if the steric configuration of the amino‐acid residues of both Nα‐Lauroyl‐Arginine and Nα‐Lauroyl‐Lysine methyl ester could influence their antibacterial effect. For this purpose the methyl esters of Nα‐Lauroyl‐D‐Arginine, Nα‐Lauroyl‐DL‐Arginine and Nα‐Lauroyl‐DL‐Lysine have been prepared. Their antibacterial activity has been evaluated and compared to that shown by Nα‐Lauroyl‐L‐Arginine and Nα‐Lauroyl‐L‐Lysine methyl ester derivatives. Our results show that the mechanism of action of these Nα‐Lauroyl‐amino‐acid derivatives against the bacteria cells is not influenced by the stereochemistry of the compound.
Sucrose Polyester (SPE) ‐ A Non‐Caloric Fat
Authors: Boggs R. W. 
Published: November 2006

AbstractSucrose polyester is non‐absorbed and, therefore, a noncaloric fat containing between 5‐8 fatty acids esterified to a sucrose molecule. Those fatty acids esterified to the sucrose dictate the physical properties of the resulting fat ranging from a solid to a liquid. Sucrose polyester is resistant to lipase activity thereby resulting in its non‐absorption and noncaloric nature. The presentation will discuss sucrose polyester's (non) metabolism, physical properties, toxicity, clinical studies, as well as acceptance in animals and humans. The chemical synthesis schemes for sucrose polyester production in kilogram amounts has been developed and will be discussed. Sucrose polyester has been exposed to humans for cholesterol lowering, weight reduction, appetite control, and diabetes. Results will be discussed. Sucrose polyester has been found to be safe following extensive toxicology testing in multiple species. Overall assessment of sucrose polyester's safety will be discussed. A review of sucrose polyesters development to product forms will be the subject of this presentation.
Lipid Profile and Fatty Acid Composition of Moth Bean (Vigna aconitefolia) Seeds
Authors: Shet M. S. , Murugiswamy B. , Madaiah M. 
Published: November 2006

AbstractThe seeds of moth bean (Vigna aconitefolia) were found to contain 4.5 % of lipid. Fractionation of this lipid by silicic acid column chromatography yielded 44.5 % neutral lipids (NL), 23.4 % glycolipids (GL) and 32.1 % phospholipids (PL). Fatty acid composition of the total lipid and lipid fractions showed that palmitic acid (37.3‐54.7 %), stearic acid (7.8‐8.0%) oleic acid (6.8‐13.9 %) linoleic acid (23.1‐35.6 %) and linolenic acid (3.0‐10.0%) are the major fatty acids. The phospholipid fraction was found to be different from the rest in containing higher palmitic acid (54.7%) and lower unsaturated fatty acids.
Quantitative Bestimmung cyanogener Glykoside in Linum usitatissimum. Mit Hilfe der HPLC
Authors: Schilcher H. , Wilkens‐Sauter Meike 
Published: November 2006

AbstractMit Hilfe der HPLC ist es möglich, die in Linum usitatissimum L. vorhandenen cyanogenen Glykoside Linustatin, Neolinustatin, Linamarin und Lotaustralin nun auch einzeln quantitativ zu erfassen. Dies ist nicht nur von Interesse für die Erforschung der Biosynthese, sondern insbesondere für die toxikologische Bewertung von Leinsamen. In 481 Leinsamenproben konnten mittels HPLC und DC nur die Diglykoside Linustatin und Neolinustatin nachgewiesen werden, nicht dagegen die Monoglykoside Linamarin und Lotaustralin. Die mittels HPLC ermittelten HCN‐Werte lagen im Durchschnitt um 2% niedriger als die photometrisch bestimmten HCN‐Gesamtwerte.
The Biosynthesis, Absorption and Tissue Distribution of Dietary Shellfish Sterols in the Crab

Published: November 2006

AbstractThe present paper deals with the biosynthesis, absorption and tissue distribution, and the origin of sterols in the crabs, Cancer majester. After the administration of isotopic mevalonate and isotopic cholesterol to crabs, the sterols were isolated by the digitonine method. The identification and sterol compositions were determined by gas‐liquid chromatography, and gas chromatography‐mass spectrometry.The results indicated that C. majester fail to utilize mevalonate to synthesize cholesterol, and are incapable of the bioconversion of cholesterol to other sterols. The sterols found in their tissues may originate from dietary sources.

Authors: Pongracz G. 
Published: November 2006

AbstractHeadspace gas analysis with a fused silica capillary PVMS 50 M column was examined for the quantitative determination of some volatile alkanes particularly pentane in edible oils. The relationship between chromatographic peak areas and pentane added in various concentrations was linear between 0.5 and 10 ppm. Significant correlations between sensory evaluation and concentration of pentane were found.
Report from a U.S. conference on essential tremor
Authors: Elble Rodger J. 
Published: November 2006

AbstractSeventy researchers met in Washington, DC, on 20–21 October 2005 to identify and discuss the most pressing research issues in essential tremor (ET). The conference attendees concluded that the following six objectives are of immediate and overriding importance: (1) a collaborative network of research centers; (2) an international committee for developing a standard protocol for the diagnosis and quantification of ET; (3) the identification of one or more genes for ET; (4) a centralized repository of DNA and, ideally, immortalized cell lines from well‐characterized ET families and healthy controls; (5) a reliable and efficient repository of optimally prepared and categorized brain samples for hypothesis‐driven neuropathological examinations in well‐characterized ET patients; and (6) animal models of ET for screening promising drugs. The conference attendees hope that this statement from the United States will engender international collaboration in finding a cure for ET. © 2006 Movement Disorder Society

Published: November 2006

AbstractMitochondrial disorders share common cellular consequences: (1) decreased ATP production; (2) increased reliance on alternative anaerobic energy sources; and (3) increased production of reactive oxygen species. The purpose of the present study was to determine the effect of a combination therapy (creatine monohydrate, coenzyme Q10, and lipoic acid to target the above‐mentioned cellular consequences) on several outcome variables using a randomized, double‐blind, placebo‐controlled, crossover study design in patients with mitochondrial cytopathies. Three patients had mitochondrial encephalopathy, lactic acidosis, and stroke‐like episodes (MELAS), four had mitochondrial DNA deletions (three patients with chronic progressive external ophthalmoplegia and one with Kearns–Sayre syndrome), and nine had a variety of other mitochondrial diseases not falling into the two former groups. The combination therapy resulted in lower resting plasma lactate and urinary 8‐isoprostanes, as well as attenuation of the decline in peak ankle dorsiflexion strength in all patient groups, whereas higher fat‐free mass was observed only in the MELAS group. Together, these results suggest that combination therapies targeting multiple final common pathways of mitochondrial dysfunction favorably influence surrogate markers of cellular energy dysfunction. Future studies with larger sample sizes in relatively homogeneous groups will be required to determine whether such combination therapies influence function and quality of life. Muscle Nerve, 2006

Published: November 2006

AbstractAimsA 2.5‐year outcome analysis was performed on patients who underwent transvaginal repair of total pelvic organ prolapse with single polypropylene mesh. A description of the repair technique using a tension‐free 4‐point fixation is also reviewed.MethodsAfter proper vaginal dissection, a specially fashioned “H” shaped polypropylene mesh is positioned and fixed at 4‐points. With a single piece of mesh, the anterior arms provide mid‐urethral and bladder neck support, the mid‐portion of the mesh corrects anterior compartment defects, and the posterior arms aid in vaginal vault suspension. Initially, bone anchors were utilized for anterior fixation, but currently a tension‐free method is used. A retrospective analysis using chart review was performed on 96 patients who underwent this procedure from January 2000 to June 2005. Additional information was gathered by a telephone survey using a questionnaire. Statistical analysis was performed using Student's t‐test, with Sigma Stat®.ResultsSeventy‐six patients (79%) were available with a mean follow‐up time of 30.7 ±  1.7 months and mean age of 69.3 ± 11.3. Among those with follow‐up, 36 patients (47.4%) underwent concurrent hysterectomies. Recurrence of prolapse was reported by four patients (5.2%). Sixty‐eight patients (89%) were completely dry or almost dry, defined as an occasional leak. For those with preoperative incontinence (n = 36), average pad use per day decreased significantly from 2.1 ± 0.4 to 0.8 ± 0.2 (P < 0.005) postoperatively. Twelve patients (15.7%) reported of de novo urgency. Six patients required reoperation including excision of vaginal mesh erosion (2), uretholysis for obstruction (1), removal of palpable vaginal suture (1), and recurrent SUI (2). Among the 21 patients who are sexually active, 19 denied any dyspareunia (90.4%). Patient satisfaction was high, as the mean value was 7.9 ± 0.3 on a scale of 1 (least satisfied) to 10 (most satisfied).ConclusionsTransvaginal repair of complete pelvic prolapse using polypropylene mesh is a safe and efficacious option, with minimal recurrence of prolapse and SUI. While two patients had vaginal erosions, no urethral or bladder erosions occurred. Patient satisfaction was overall favorable. Neurourol. Urodynam. © 2006 Wiley‐Liss, Inc.
Anethole, a potential antimicrobial synergist, converts a fungistatic dodecanol to a fungicidal agent
Authors: Fujita Ken‐ichi , Fujita Tomoko , Kubo Isao 
Published: November 2006

AbstractAnethole shows synergistic effects on the antifungal activities of phytochemicals including polygodial and (2E)‐undecenal against Saccharomyces cerevisiae and Candida albicans. It was found that a fungistatic dodecanol combined with a sublethal amount of anethole showed a fungicidal activity against S. cerevisiae. The MIC of dodecanol quickly reduced cell viability, but the cell viability recovered shortly after and then finally became no longer different from the control, indicating that the effect of dodecanol on this yeast was classified as sublethal damage. On the other hand, anethole completely restricted the recovery of cell viability. Therefore the expression of the synergistic effect was probably due to a blockade of the recovery process from dodecanol‐induced stress. Copyright © 2006 John Wiley & Sons, Ltd.
Methanol extract of the seaweed Gloiopeltis furcata induces G2/M arrest and inhibits cyclooxygenase‐2 activity in human hepatocarcinoma HepG2 cells
Authors: Bae Song Ja , Choi Yung Hyun 
Published: November 2006

AbstractIt was previously reported that a methanol extract of Gloiopeltis furcata (MEGF), a kind of edible seaweed, inhibited the growth of several human cancer cell lines. In the present study, the effect of MEGF on the growth of human hepatocarcinoma HepG2 cells and its effect on the cyclooxygenases (COXs) expression were investigated. MEGF markedly reduced the viability of HepG2 cells and induced the G2/M arrest of the cell cycle in a concentration dependent manner. These effects were associated with the down‐regulation of cyclin A, up‐regulation of cyclin‐dependent kinase (Cdk) inhibitor p21 (WAF1/CIP1) and dephosphorylation of Cdc25C. Furthermore, it was found that MEGF decreased the levels of COX‐2 mRNA and protein expression without significant changes in the levels of COX‐1, which was correlated with a decrease in prostaglandin E2 (PGE2) synthesis. These findings indicate that MEGF may have a possible therapeutic potential in hepatoma cancer patients. Copyright © 2006 John Wiley & Sons, Ltd.

Published: November 2006

AbstractCarbon tetrachloride (CCl4) causes chronic hepatitis, featuring an increase in hepatic hydroxyproline, spleen weight and serum GPT levels and a decrease in plasma albumin levels. Crude extracts of fresh whole plants of Anoectochilus formosanus showed inhibition of chronic hepatitis induced by CCl4 in mice. Bioactivity‐guided fractionation and spectroscopic analysis revealed that kinsenoside was the most active compound. In an in vitro study, the LD50 values for H2O2‐induced cytotoxicity in BALB/c normal liver cells were significantly higher after kinsenoside pretreatment than after vehicle alone, further confirming that kinsenoside shows significant antihepatotoxic activity.

70 Jahre Forschungsinstitut für Stärkefabrikation, Berlin
Authors: Wegner Hans 
Published: November 2006

Abstract…Schon lange war von hervorragenden Persönlichkeiten des Vereins der Spiritusfabrikanten der Wunsch ausgesprochen, daß in gleicher Weise, wie die Preßhefebrikation, auch der Stärkefabrikation in unserem Verein eine Stätte bereitet werde. Nicht nur in der Weise, daß das Vereinsblatt auch über die Fortschritte dieses Gewerbes referiere, sondern dadurch, daß eine besondere Abteilung des Laboratoriums geschaffen werde, welche sich ausschließlich der Frage der Stärkefabrikation widme. Die äußere Veranlassung zur versuchsweisen Erfüllung dieser Forderung wurde der Neubau des Vereinshauses. Das schöne Laboratorium wird genügen, ohne die Interessen der Forschung im Dienste der Gärungsgewerbe zu schädigen, den durch das gleiche Rohmaterial verwandten Gewerbszweigen eine Unterkunft zu gewähren. Es ist nun gelungen, in Herrn Dr. Saare eine Persönlichkeit zu finden, welche geeignet sein wird, selbständig diese Forschungsrichtung zu kultivieren.Die auf Donnerstag, den 15. Februar, vormittags, im Club der Landwirte angesetzte Versammlung wird Gelegenheit bieten, manche wichtige Frage, den Stärkehandel betreffend, zu diskutieren, insbesondere werden aber die Mitteilungen über bereits begonnene chemische Untersuchungen, sowie die Frage der Rieselung des Stärkewassers, wie wir hoffen, das Interesse erregen….

Interaction of Monoglycerides with Starches
Authors: van Lonkhuysen H. , Blankestijn J. 
Published: November 2006

AbstractIn bread‐making practice, the emulsifier glycerolmonostearate (GMS) is commonly used as an improving agent, though the mechanism of its action is not fully elucidated. Most of earlier studies have been made on starches in molecular solution. The present investigation deals with interactions of the emulsifier (in fact a mixture of glycerolmonostearate and ‐palmitate) and starches in suspension, at temperatures ranging from 30–90°C.The quantity of monoglycerides bound by the starch was determined by sampling the reaction vessel at time intervals and re‐extracting the monoglycerides that were left free in the suspension. Quantitative determination was achieved with the aid of gas‐chromatography.It was found that at 30 °C, part of the monoglycerides is irreversibly bound by the starch granules; during gelatinization, the quantity of emulsifier bound shows a considerable increase to reach, at 90 °C, an equilibrium at a higher level. Probably, the monoglyceride molecules penetrate into the swollen starch granules to form an insoluble complex with amylose.Various starches included in the study showed essentially similar behaviour, but were quantitatively different in their capacity to bind monoglyceride. At 30 °C, wheat starch binds a greater part of added monoglycerides than does cassava starch; at 90 °C the situation is the reverse.
Modification of the Hörmann technique of hyoid suspension in obstructive sleep apnoea
Authors: Tschopp K P 
Published: November 2006

Hyoid suspension is a procedure to stabilise the retrolingual space in obstructive sleep apnoea. Using the Hörmann technique, a steel wire is slung around the body of the hyoid and fixed to the upper rim of the thyroid cartilage. It was observed, however, that the steel wire may lie very superficially to the pharyngeal mucosa. Evaluation of computed tomography (CT) scans showed a mean distance between the hyoid and the pharynx of only 3 mm. A modification is presented by threading a steel wire through a hole that is drilled through the hyoid bone. Thus pharyngeal exposure of the steel ligature and possible perforation of the mucosa is avoided.
Management of benign inverted sinonasal papilloma avoiding external approaches

Published: November 2006

Even though endoscopic removal of inverted papillomas has gained popularity, many studies advocate supplementary external approaches. The impact of including the current surgical staging system into the pre-operative clinical and radiological assessment has not been systematically evaluated. We present our experience with total endoscopic management of inverted papillomas and compare the accuracy of the pre-operative predicted extent of surgery, with the actually performed surgery.From 1997 to 2005 data from 51 patients with inverted papillomas were prospectively collected and subsequently reviewed. All have been operated on endoscopically without an external approach.The overall recurrence rate was 3.9 per cent. Pre-operative prediction of extent of surgery was accurate in 26 of 51 (51 per cent). The main reasons for the inaccurate pre-operative prediction were the variable sizes and locations of the inverted papilloma bases, particularly in the maxillary sinus and the frontal recess. Our results encourage us to recommend endoscopic management as the standard treatment of benign inverted papillomas.
