    Description / Table of Contents: 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.
    Notes: 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.

    Notes: Abstract. Objective: Dapsone (4,4'diaminodiphenylsulfone) is effective in treating leprosy, chronic inflammatory conditions and opportunistic infections in HIV patients. By the oral route, the sulfone is metabolized to monoacetyldapsone (MADDS) and dapsone hydroxylamine (DDS-NOH). We have addressed the question as to whether these dapsone metabolites have anti-inflammatory properties of their own in vivo.¶Treatment and Methods: After two weeks topical pre-treatment with MADDS (1%), DDS-NOH (1%) and clobetasol proprionate (CP; 0.05%) dissolved in acetone, as a reference, 10 ng leukotriene B4 (LTB4) were applied on the upper arms of eight healthy volunteers. After 24 h, biopsies were taken and the polymorphonuclear leukocytes (PMN) were quantified fluorometrically using elastase as marker enzyme.¶Results: MADDS did not show any inhibitory activity on trafficking of PMN compared to the corresponding control and nontreated area (untreated: 790 ± 450 PMN/10 μg skin; p 〉 0.05, acetone: 840 〉 578 PMN/10 μg skin; MADDS: 1099 〉 556 PMN/10 μg skin), whereas DDS-NOH caused a statistically significant inhibition of PMN accumulation as did the reference CP (DDS-NOH: 128 〉 143 PMN/10 μg skin; CP: 86 〉 131 PMN/10 μg skin, p 〈 0.01).¶Conclusions: These results indicate that DDS-NOH has anti-inflammatory potential which might contribute to the effectiveness of dapsone therapy.

    Notes: Summary In an eight-choice reaction task, the influence of erroneous responses upon the temporary changes in the level of heart rate (HR) was studied. It was shown that after errors there was a short-term deceleration of the HR-level, while after correct responses an accelerating tendency was found. This phenomenon has to be regarded as an additional source of fluctuations of the HR-level. Therefore, it has to be taken into account when suppression of sinus arrhythmia is used for assessing the level of mental load.

    Notes: Abstract An analysis of the polypeptides synthesized in the salivary glands of late fourth instar R. americana larvae was accomplished by the use of electrophoresis followed by fluorography of in vitro labelled proteins. It was possible to detect five polypeptides which are synthesized only when the giant DNA puffs occur. One of these polypeptides was tentatively assigned to DNA puff B2 and another to the DNA puff C3. This assignment was based on correlations of polypeptide labelling, puffing patterns and RNA synthesizing capacity of the puffs in different sections of the gland during development. The possible meanings and implications of these DNA puffs are discussed.

    The abdominal muscle receptor organ in Astacus leptodactylus (Crustacea) (1979)

    Notes: Summary The structure of both the slow- and the fast-adapting abdominal muscle receptor organ of Astacus leptodactylus is described with particular reference to differences between the two systems. The receptors are composed of a thin muscle that extends from the front edge of one segment to the front edge of the following and a sensory cell connected with this muscle. In the zone where the sensory cells enter their respective muscle, muscle fibers are reduced (zone of relative muscle exclusion=ZRME) and partly replaced by connective tissue. The occurrence of dendritic processes of both the slow and the fast neurons is confined to this zone. The following differences between the two receptor types are established: (1) The fast receptor muscle reveals a smaller sarcomere length than the slow receptor muscle and a higher myosin/actin filament ratio. (2) Muscle fibers that pass the ZRME are always found at its periphery in the fast system, separated from dendritic processes by layers of connective tissue, while in the slow system muscle fibers frequently are intermingled with the sensory elements. (3) The ZRME of the slow receptor is 20–30% longer than that of the fast receptor. (4) The dendritic varicosities of the slow neuron, on an average, contain many more mitochondria than those of the fast neuron. (5) Dendritic processes (fine twigs as well as varicosities) are juxtaposed to the sarcolemma of the muscle fibers only in the slow system; in the fast system dendrites and muscle are spatially separated by connective tissue. It is assumed that these differences between the two receptor types arep at least in part responsible for the different thresholds observed in physiological experiments.

    Notes: Synopsis The application of OsO4 plus K3[Fe(CN)6] as a secondary fixative following aldehyde fixation, permitted demonstration of the presence of 30–300 nm ‘membrane-bound’ particles in xanthomatous tissue. With the same fixation method, isolated low density lipoprotein particles in a fibrin matrix could be observed in the transmission electron microscope in a way permitting comparison with similarly fixed tissue. However, isolated particles of very low density lipoproteins treated in the same way as low density particles had an irregular appearance and a diameter varying between 30 and 80 nm.

    Comparative study on peroxidatic activity in inflammatory cells on cutaneous and peritoneal implants (1979)

    Notes: Summary Inflammatory reactions were evoked by simultaneous implantation of pieces of Melinex plastic in the subcutaneous tissues of the dorsum and in the peritoneal cavity of rats. The cellular composition of the Melinex-adherent cells and their peroxidatic (PO) activity were investigated in relation to the duration of implantation. Several striking differences were found between the subcutaneous and peritoneal implants. On the 7th and 14th days, multinucleated giant cells were abundantly present on the subcutaneous implants, whereas they were relatively rare on the peritoneal implants. The subcutaneous implants bore no mast cells and only a few eosinophilic granulocytes, but both types of cell were observed frequently on the peritoneal implants. Macrophages and multinucleated giant cells on the subcutaneous implants show PO activity only in the granules or are PO negative. On the peritoneal implants three types of macrophages can be distinguished: exudate macrophages which have PO activity restricted to granules or are PO-negative; macrophages with PO activity in granules and both the rough endoplasmic reticulum (RER) and nuclear envelope; and resident macrophages with PO activity only in the RER and nuclear envelope. In addition, two types of multinucleated giant cells are found, one with and the other without PO activity in the RER and nuclear envelope. Multinucleated giant cells with PO activity in the RER and nuclear envelope as well as exudate macrophages with PO activity in the RER and nuclear envelope were mainly found 32 h and 3 days after implantation of the Melinex in the peritoneal cavity. These findings are discussed in the light of current knowledge of the PO activity in macrophages and multinucleated giant cells. It is concluded that the appearance of PO activity in the RER and nuclear envelope of exudate macrophages and multinucleated giant cells is in all probability a transient phenomenon, and that there is no objective evidence to support the opinion that exudate macrophages with PO activity in the RER and nuclear envelope are transitional cells between exudate and resident macrophages.

    Notes: Summary Rat blood monocytes contain granules of two types, primary and secondary granules, which can be distinguished on morphological grounds. Secondary granules have a halo between the limiting membrane and the matrix; primary granules have no halo and are generally more elongate than the secondary granules. In addition, there are differences in the distribution of the diameters of these two types of granules. The cytochemical characteristics of the peroxidatic activity of these granules were investigated by using different prefixation conditions in combination with a number of DAB media differing in pH and H2O2 concentration. Prolongation of the prefixation and increasing the pH of the incubation medium increased the staining intensity of the secondary granules and decreased the staining intensity of the primary granules. In unfixed cells peroxidatic activity could be demonstrated only in the primary granules. It is concluded from the present findings that peroxidase occurs in primary granules and not in secondary granules, whereas catalase is present in secondary granules but probably not in primary granules. No evidence was found for the presence of microperoxisomes in rat blood monocytes.

    Notes: 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.
