    Notes: Abstract To achieve its health goals, the United States must reduce the disproportionate burden of illness and poor health borne by urban populations. In the 20th century, patterns of immigration and migration, changes in the global economy, increases in income inequality, and more federal support for suburbanization have made it increasingly difficult for cities to protect the health of all residents. In the last 25 years, epidemics of human immunodeficiency virus infections and substance abuse and increases in homelessness, lack of health insurance, rates of violence, and concentrations of certain pollutants have also damaged the health of urban residents. Several common strategies for health promotion are described, and their relevance to the unique characteristics of urban populations is assessed. To identify ways to strengthen health promotion practices in U.S. cities, lessons have been taken from five related fields of endeavor: human rights, church- and faith-based social action, community economic development, youth development, and the new social movements. By integrating lessons from these areas into their practice, public health professionals can help to revitalize the historic mission of public health, contribute to creating healthier cities, and better achieve national health objectives.

    Description / Table of Contents: Summary Complement fixation tests and precipitin reactions in agar with gliadin as antigen were compared in cases of celiac disease. Pseudopositiv reactions did not occur in 285 controll cases when the precipitin test of Ouchterlony was used, but were seen in two cases of 189 controlls with the complement fixation test. If only one of the two reactions was positive and this was considered as a sufficient proof for the formation of gliadin antibodies those were found in 11 of 12 cases of clinically confirmed celiac disease. In those cases the agreement of the two methods was good, but not so in not confirmed cases where complement fixation tests gave more positive results than the precipitin reaction. It is proposed to use both methods for diagnostic help and to repeat the tests if the reactions are negativ.
    Notes: Zusammenfassung Die Methoden der Komplement-bindung und der Präcipitinreaktion in Agar mit Gliadin als Antigen wurden vergleichend auf ihre Anwendbarkeit in der Diagnostik der Cöliakie geprüft. Beim Präcipitinversuch kamen pseudopositive Reaktionen bei 285 Kontrollen nie vor, bei der Komplementbindung zweimal bei 189 Kontrollen. Zwölf sichere Cöliakiefälle ergaben vergleichend geprüft acht bzw. neun positive Reaktionen, wobei die negativen Befunde für die beiden Verfahren nicht das gleiche Serum jeweils betrafen. Wurde die positive Reaktion in nur einer Methode als ausreichend betrachtet, so war das Ergebnis: elf positive Reaktionen auf zwölf Fälle. Während bei klinisch bestätigter Cöliakie die Übereinstimmung der beiden Methoden gut war, war dies bei den bloßen Verdachtsfällen nicht der Fall. Hier gab es bei der Komplementbindung mehr positive Resultate als bei der Präcipitinreaktion. Es wird vorgeschlagen, beide Methoden nebeneinander anzuwenden und sie bei negativem Ausfall zu wiederholen, wobei die gegebenen diätetischen Richtlinien einzuhalten sind. Als Antigen kann ein Glycerinextrakt aus Gluten verwendet werden, wenn gereinigtes Gliadin nicht zur Verfügung steht. Extrakte mit heißem Wasser geben zu viele pseudopositive Reaktionen.

    Notes: Summary From the ranks of the colourless hydroxyflavans, four differenthydroxyflavan-3-ols(catechins and epi-catechins), as well as eight hydroxyflavan-3,4-diols, have so far been encountered in nature. These substances are also procurable by synthesis. On treatment with hot water or dilute acids, they are easily converted into soluble tannins or insoluble phlobaphenes. The mechanism of the self-condensation is explained using catechin via the isolation of a dimerie product. A probable path for the self-condensation of the diols has been indicated. In contrast to the products of their self-condensation, the monomeric polyhydroxyflavans are not real tannins. A particular accumulation of phenolhydroxyl groups in the molecule, the tendency to form supersaturated solutions and low solubility in water in the — generally not attainable — crystalline state are prerequisites for tanning properties. In nature, the self-condensation of polyhydroxyflavans proceeds (e. g. in the wood ofAcacia catechu or in Quebracho Wood) without the assistance of enzymes. Dehydrogenative polymerisation occurs with formation of brown or red phlobaphenes (e.g. in cocoa beam) which are generally insoluble.

    Notes: Summary Natural and purified proteins were split by crystallized pepsin. The break down of substrates was followed by a turbidimetric method. pH optima were found from 1.5 to 3.8. Only unpurified egg albumin had two optima, crystallin had one in the acid range. Ovomucoid not being split by pepsin, the second peak at pH 3.79 is referred to conalbumin. While the disintegration of caseinogen becomes slow with decreasing acidity, this is not true for casein (paracasein) which is well split up to pH 3.28 (cows casein) or 3,73 (womens casein). Nevertheless, the optimum is in the range of 1.5–2.0, like most proteins. Above this limit, the following optima were found: fibrinogen 2.93, thrombin 2.78, edestin 3.08, crystallized hemoglobin 3.19, conalbumin 3.79.

    Notes: Summary Peptic and tryptic digestion of gluten and gliadin leaves a part of the substrates unaltered after precipitation at pH 4.5. Complement fixation test of the soluble part remains positive even after autoclaving of this part at pH 4.5, but not so after autoclaving at alkaline reaction. Positive reactions are also given by the components which are not ultrafiltrable while the ultrafiltrates give negative reactions. This means that positive reactions originate from residues of gluten or gliadin respectively. The question posed in the title must be answered in the negative. Products of peptic-tryptic digestion of gliadin do not have antigenic properties.
