    Notes: Summary Nucleolar organizing regions (NORs) ofNigella damacena were detected at the secondary constricted regions on 3 pairs of chromosomes by the silver staining method. The size of the NORs were found to be correlated with the size of the nucleoli.

    Notes: We have deqeloped a para-carotid approach for internal jugular cannulation which utlizes only the carotid artery as a landmark. This technique allows us to locatedhe puncture site regardless of an individual patient's physical, skeletal or postural variations. This study was undertaken in the period from January 1979 to June 1980 on 456 consecutive patients in a wide range of age groups and various clinical conditions. The overall success rate was 96.1%. The only complications encountered during our study were Five carotid artery punctures with formation of two haematomas.

    Notes: Acid phosphatase activity was examined ultracytochemically in gingival specimens to elucidate the response of plasma cells to Russell's bodies. The acid phosphatase activity was discernible in lysosomes of various morphology, some of which contained Russell's bodies. The acid phosphatase activity was stronger in the peripheries of such lysosomes, but weak activity was also found inside Russell's bodies. These findings indicated that at least some of Russell's bodies formed within the plasma cells were degraded in autophagolysosomes.

    Description / Table of Contents: Zusammenfassung Zur Präparierung großer Einkristalle wurde rekristallisiertes Tetraoxymethylen in destilliertem Wasser von pH 8 in eine Ampulle bei einem reduzierten Quecksilberdruck von 1 mm eingefüllt und in einem Ofen mit einem Temperaturgradienten von 6 °C/cm kristallisiert. Die Abkühlgeschwindigkeit der Ampulle betrug etwa 6 cm/Tag für die Präparation eines Einkristalls mit 1 cm Ø und 3 cm/Tag für einen solchen mit 2 cm Ø. Der optimale Winkel am spitzen Ende der Ampulle, wo der Keimkristall gebildet wird, betrug etwa 40°. Dieb-Achse des Einkristalls war parallel zur Wachstumsrichtung, d. h. zur Wand der Ampulle. Der Kristall wurde durch Röntgenstrahlen polymerisiert unter Bedingungen, die das Wachsen eines Zwillingskristalls vermeiden. Das erhaltene Polyoxymethylen war porös, doch konnte eine Polymerisationsausbeute von 100% nicht erhalten werden. Doch war der Einkristall so zäh, daß für Messungen eine Probe mit dem Diamantschneider abgeschnitten werden konnte. Die Faserachse war parallel zur Wandrichtung der Ampulle. Das kristalline Material enthielt keine sogenannten amorphen Bereiche, allerdings Defekte. Es war durch extrem hohe Orientierungen der Polymerketten charakterisiert.
    Notes: Summary In order to prepare a large single crystal, tetraoxymethylene recrystallized by distilled water adjusted to pH 8 was sealed in an ampoule at a reduced pressure of 1 mm Hg and was crystallized in a furnace with the temperature gradient of 6 °C/cm. The lowering rate of the ampoule was required to be 6 cm/day for preparing the single crystal with 1 cm diameter and to be 3 cm/day for one with 2 cm diameter. The optimum angle at the pointing end of the ampoule, where a seed crystal is formed, was about 40°. The b-axis of the obtained single crystal was parallel to the direction of the crystal growth i. e. the wall of the ampoule. It was polymerized byγ-ray under conditions which prevent the growth of the twin crystal. The obtained polyoxymethylene was porous, because the polymerization yield of 100% could not be attained. However, it was so tough that a specimen for measurements could be cut down by a diamond cutter. Its fiber axis was parallel to the direction of the wall of the ampoule. It did not contain the so-called amorphous regions, although it did contain defects. It was characterized with the extremely high orientation of the polymer chains.

    Notes: Zusammenfassung Versuche mit14C-markiertem Carcinogen MNNG ergaben an Ratten nach einmaliger Verabreichung der Substanz eine vorwiegend über die Niere erfolgende Elimination. Die Metabolite von MNNG in Verknüpfung mit verschiedenen Stoffwechselstufen und ihre Verteilung im Gewebe wurden näher verfolgt.

    Notes: Summary Bacterial chromatophores have been isolated from a purple non-sulfur bacterium (Rhodopseudomonas capsulata) by sonication and immobilized within various supports. In each case, the activity yield after immobilization and the storage stability (under dark conditions at 4°C) have been determined. Some preliminary comparative experiments concerning the ATP production in a batch reactor are presented for native and immobilized chromatophores.
