    Notes: Summary The afferent and efferent connections of the prelunate visual association area V4 of macaque monkeys were investigated by means of the horseradish peroxidase (HRP) method. The specific thalamic afferents from the dorsolateral segment of the medial pulvinar and the lateral segment of the inferior pulvinar were topographically organized. A band of cells was labelled in the intralaminar nuclei (nucl. centr. med. and lat., reaching into LD and the most dorsal part of VL), and a few cells in the interlaminar layers of the lateral geniculate body. Other diencephalic afferents included the claustrum, the nucleus basalis Meynert and the pars compacta of the substantia nigra. Ipsilateral cortical areas which projected into V4 included area 18 (V2), the inferior parietal cortex, the anterior and posterior parts of the superior temporal sulcus, the frontal eye fields and the temporo-basal association cortex on the lateral half of the parahippocampal gyrus and around the occipito-temporal sulcus. In the contralateral cortex, discontinuous regions in areas V4 and V5 on the prelunate gyrus and some cells at the 17/18-border were labelled. All regions in which labelled cells were found and, in addition a restricted region in the dorsal cap of the head and the tail of the caudate nucleus showed fibre and terminal labelling. In addition mesencephalic afferents and efferents were identified but not investigated in detail. An attempt to estimate the quantitative contribution of the various afferent systems to the prelunate cortex was made by counting the labelled cells in the different areas. The afferent and efferent organization of the prelunate visual association area indicates that it is incorporated in a network of cortical and subcortical regions involved in various aspects of visual behavior.

    Description / Table of Contents: Summary 1. The separate determination of ketone bodies, glucose and glycerol in umbilical cord artery and vein, placental artery and vein resulted in elevated levels of glycerol and ketone bodies in placental blood compared to cord blood. 2. It is concluded that for experimental purposes cord blood is not to be replaced by placental blood. 3. In analysing the possible facts we drew the conclusion that these results indicate a representation of the placental metabolism. Hemodynamic factors were not to be excluded, however. 4. The comparison of placental with cord blood under normal and pathological conditions will possibly add to the study of placental metabolism in situ.
    Notes: Zusammenfassung 1. Die Bestimmung von Ketonkörpern, Glucose und Glycerin getrennt in Nabelartcrie, Nabelvene, Placentararterie und Placentarvene ergab für Glycerin und Ketonkörper im Placentarblut meist etwas höhere Werte als im Nabelschnurblut. 2. Es folgt daraus, daß es nicht zulässig ist, aus experimentellen Gründen Placentarblut an Stelle von Nabelschnurblut zu verwenden. 3. Durch die Analyse der möglichen Ursachen kamen wir zu dem Schluß, daß es sich bei diesen Veränderungen wahrscheinlich um eine Widerspiegelung des placentaren Stoffwechsels handelt. Hämodynamische Einflüsse jedoch sind nicht auszuschließen. 4. Es ist möglich, daß der Vergleich von Placentarblut und Nabelschnurblut unter normalen und pathologischen Bedingungen zum Studium des Stoffwechsels der Placenta in situ einen Beitrag liefern kann.

    Description / Table of Contents: Summary Glucose tolerance tests and arginine infusions were performed in 60 fullterm newborn infants at 1, 4, and 7 days of age. Glucose and arginine infusions were followed by an initial decrease of GH1 which was followed by an increase of GH levels exceeding base line values. Two hours after infusions GH levels were lower than in the beginning. The most pronounced changes of GH concentrations were observed in the youngest age group. FFA2 and glycerol levels initially decreased after glucose and arginine infusion. It is suggested that GH plays an important role in protein synthesis and lipolysis particularly during the first days of life.
    Notes: Zusammenfassung Glucoseinjektionen (0,33 g/kg Körpergewicht in 15 sec) und Arginin-Infusionen (0,5 g/kg Körpergewicht in 30 min) bei Neugeborenen verschiedenen Alters (1–2, 4 und 7 Tage) führten zum Anstieg des STH im Blut und zur Abnahme der freien Fettsäuren und des Glycerins. Die stärkste STH-Reaktion wurde bei den jüngsten Neugeborenen (1–2 Tage alt) beobachtet.
