    Beschreibung / Inhaltsverzeichnis: Summary This study was conducted by the Technical University of Munich-Weihenstephan on behalf of the Department of Education of the city of Munich. A total of 82 children as well as their parents and 23 kindergarten teachers in five Munich kindergartens were questioned about their food preferences, and their sociocultural data were gathered. The results showed that the nationality and the religion of the mother were fundamental to the origin and consolidation of the eating habits of the children. Other important und influencing factors were: the peer group and the teachers in the kindergarten, the father's job, the sex and the age of the children. When comparing the food preferences of the children and their role models, it was found that the preferences and aversions were more similar to those of their own mothers/teachers/members of the peer group than to those of children of other peer groups, other parents or other teachers.
    Notizen: Zusammenfassung Im Auftrag des Schulreferats der Stadt München wurden an der Technischen Universität München-Weihenstephan insgesamt 83 Kinder sowie deren Eltern und 23 Erzieherinnen in 5 Münchner Kindergärten zu ihren Nahrungspräferenzen befragt und ihre sozial-kulturellen Einflüsse untersucht. Die Ergebnisse zeigten, daß die Staatsangehörigkeit und Religion der Mutter wesentlich zur Entstehung und Festigung der Verzehrsgewohnheiten von Kindern beitragen. Als weitere wichtige Einflußfaktoren erwiesen sich die Kindergartengruppe, der Beruf des Vaters, das Geschlecht und das Alter der Kinder. Beim Vergleich der Nahrungspräferenzen von Kindern und ihren Bezugspersonen zeigte sich, daß die Vorlieben und Abneigungen von Kindern und ihren eigenen Müttern/Erzieherinnen/Gruppenkameraden ähnlicher waren als die von Kindern und Müttern/Erzieherinnen/Gruppenkameraden anderer Kindergartenkinder. Daraus wird der Schluß gezogen, daß die eigene Mutter und Bezugspersonen einen hohen Einfluß bei der Ausprägung von Nahrungspräferenzen haben.

    Notizen: Summary The peroxidatic (PO) activity of monocytes differentiating into macrophages, epithelioid cells, and multinucleated giant cells in subcutaneous granulomas was investigated with three different media for the demonstration of PO activity. Irrespective of the stage of differentiation, these cells did not show PO activity in the rough endoplasmic reticulum (RER) or nuclear envelope. In addition, it was found that the morphologically characteristic types of granule of the various cells of the monocyte line (the primary granules and secondary granules of monocytes, the macrophage granules, and the epithelioid cell granules), all have distinct cytochemical characteristics. Monocytes lose their primary and secondary granules during differentiation into mature macrophages. Simultaneously, the granules of both types become elongated and the secondary granules lose their halo. In contrast to monocytes, mature macrophages may contain a few microperoxisomes. During the differentiation of macrophages into epithelioid cells or multinucleated giant cells there is an increase in the number of microperoxisomes.

    Notizen: Summary The morphological changes occurring in monocytes during their differentiation into macrophages, epithelioid cells, Langhans-type giant cells, and foreign-body-type giant cells were investigated in foreign-body granulomas induced by subcutaneous implantation of pieces of Melinex plastic. Analysis based on Adams's (1974) criteria for discrimination between the several types of cell of the monocyte line, showed that each type has a characteristic type of granule. Primary and secondary granules, numerous in the Golgi area of monocytes were generally found close to the cell membrane and decreased in number in maturing macrophages. This was accompanied by an increase in the number of microtubules. Mature macrophages show numerous characteristic macrophage granules, which are round (average diameter: 280 nm) and have a halo between the limiting membrane and granular matrix. Mature epithelioid cells have characteristic epithelioid cell granules, and multinucleated giant cells a heterogeneous population of granules. Fusing macrophages generally have their Golgi areas facing each other, and also show a reduced thickness of the cell coat. The morphology of the multinucleated giant cell is closely related to the number of nuclei present. In Langhans-type giant cells, which generally have two to ten nuclei, a giant centrosphere with numerous aggregated centrioles is found. In transition forms between Langhans-type and foreign-body-type giant cells, which generally contain 10–30 nuclei, the centrioles show less aggregation. In the foreign-body-type giant cells, which generally have more than 30 nuclei, centrioles are virtually absent and never aggregated. These differences between the Langhans-type giant cells, the foreign-body-type giant cells, and the transition forms, support our previous finding that Langhans-type giant cells are the precursors of foreign-body-type giant cells.
