Notes: This paper treats three subjects:(1) In Sections II and III there is given a general analysis of revisions in national income data, namely the sources of revisions are enumerated and the conclusions that might be drawn are discussed in some detail.(2) Section IV gives a description of the history of revisions in national income estimates for the FRG (Federal Republic of Germany) for the period 1949–1965. The general revisions are classified according to their causes.(3) Sections V to VII give a statistical analysis of the revisions described in Section IV. Revisions in the level and in the linear annual change are characterized by their mean and their mean absolute deviation. Theil's coefficient of inequality is computed and on the basis of its decomposition a kind of analysis of variance is carried out.

Notes: Zusammenfassung Mit chemischer Methode wurden bei grösseren Tierarten die Mengen von Dopamin und Noradrenalin im Eminentia-mediana-Infundibulum-Gebiet, im mediobasalen Hypothalamus und im Endteil des Hypothalamus bei Mensch, Schwein und Rind genau bestimmt. Die höchste Konzentration von Dopamin wurde in Eminentia mediana und die höchste Konzentration von Noradrenalin im mediobasalen Hypothalamus gefunden.

Notes: Zusammenfassung Im Perikaryon der kleinen Neuronen des Nucleus arcuatus und periventricularis des Rattenhypothalamus kann man nach Fixation mit Glutardialdehyd und nach Oxydation durch Osmiumtetroxyd reduzierendes Material darstellen. Die gleichen reduzierenden Substanzen gibt es auch in der Eminentia mediana, wo sie perivasculär teilweise in Form kleiner Granula angehäuft sind oder eine bandartige Anordnung zeigen.

Notes: [Auszug] It was reported originally that DMPEA determined by this method was unique to the urine of schizophrenic patients, suggesting a close relationship between the compound and the disease5'9'10. It was found, however, that DMPEA was also excreted by non-schizophrenic, normal patients11, and later ...

Notes: Summary The ependymal cells bordering the median eminence to the third ventricle are characterised by many microvillus-like projections and bulbous cell processes of the luminal plasma membrane. The latter contain many vesicles 500–1,000 Å in diameter. Cilia with 9+2 fibrillar pattern are seen occasionally. Adhesive devices in the from of zonula adhaerens and zonula occludens are found in the apical part of the intercellular junction. Unmyelinated nerve fibres with a mean diameter of 1 μ and containing many electron dense granules of 830–1,330 Å are often seen between the ependymal cells. Two types of glial cells are found in the median eminence. One is characterised by a nucleus with dense blods of chromatin and dense cytoplasm, and it is associated chiefly with the nerve fibres in the region of the hypothalamo-hypophysial tract. The other type of glial cell is characterised by fine, uniformly distributed chromatin in the nucleus and a relatively pale cytoplasm and branched processes which terminate perivascularly in the base of the median eminence. Myelinated nerve fibres are seen only in the region of the hypothalamo-hypophysial tract. Only a part of them contain electron dense granules 1,330–2,330 Å in diameter. Three types of unmyelinated nerve fibres can be distinguished in the median eminence according to the size of the electron dense granules they contain: 1. Nerve fibres containing granules 1,330–2,330 Å in diameter. They are seen primarily in the hypothalamo-hypophysial tract, but also in the zona externa; 2. those containing granules with a mean diameter of 1,330 Å; and 3. those containing granules with a mean diameter of 1,000 Å. The last two types are both encountered in the hypothalamo-hypophysial tract, the zona externa and the perivascular region of the base of the median eminence. Under high magnification, the membrane of the granules show evidence of a trilaminar structure and the content of the granules with a low electron density appeares to consist of small microvesicles or globular components. Besides granules, these nerve fibres contain vesicles mostly 420 Å in diameter whose relative number increases towards the perivascular nerve endings. 53 per cent of the inclusions in the hypothalamo-hypophysial tract are granules and 47 per cent vesicles, while the corresponding percentages for the zona externa are 40 and 60 and for the perivascular nerve endings 20 and 80. The mean width of the pericapillary space is 1 μ, but it varies greatly. It containes many collagen fibrils and fibroblasts. The capillary endothelium is frequently fenestrated and contains many vesicles of various sizes. Two types of granules-containing cells are found in the pars tuberalis depending on the size of the electron dense granules: 1. cells containing granules with a mean diameter of 1,330 Å: and 2. cells containing granules with a mean diameter of 2,000 Å. In addition, there are occasional follicular cavities filled with amorphous material, microvilli and cilia of 9+2 fibrillar pattern.
