Es wird versucht, Beweise für die indirekte Strahlenwirkung zu erbringen und die einzelnen Reaktionsschritte, die bei Röntgenstrahlen-Wirkung auf wäßrige Lysinlösungen ablaufen, zu erkennen. Zur Untersuchung der durch HO2 oder OH-Radikale ausgelösten Wirkungen wurden 2 Versuchsreihen durchgeführt:
1. Bestrahlung bei Anwesenheit von Sauerstoff,
2. Bestrahlung bei Sauerstoffmangel.
Außerdem wurde der Einfluß der Dosis, Dosisleistung, Temperatur und verschiedener Substrat-Konzentrationen untersucht.
Schließlich wurde versucht, die experimentell gewonnenen Ergebnisse mit Hilfe von Radikalwirkungen, die sich auf
a) Decarboxylierungen,
b) Desaminierungen,
c) und Veränderungen des Kohlenstoff-Gerüstes erstrecken, zu deuten.
In this paper all the Japanese species of the family Lejeuneaceae were critically reviewed. As the result four subfamilies, twenty-one genera, and seventy-eight species were recognized under the family. Discussions were made on the relationship of the genera within the family and with other families (Tables 1-4). The new subfamily Jubuloideae was established (the type is Jubula), and the genera, Hattoria and Nipponolejeunea, were included in it. More than thirty species were reduced to synonymy under others, and eighteen new combinations were made. The seven types of distribution were recognized, according to the distribution patterns of species in Japan (Map 1, Table 5).
Neither classical scholars nor medical bibliographers have yet given adequate attention to Renaissance Latin translations of Galen. The German editors of the Corpus Medicorum Graecorum have concluded that detailed study of these versions will seldom aid materially in the reconstruction of the Greek text. Mediaeval Latin translations on the other hand, which are both literal and based On manuscripts some two to three centuries older than those used by the editors of the Aldine editio princeps, have been diligently studied by textual critics. The classical specialist tends therefore to underestimate the interest oflater versions for the historian ofideas, the medical historian and the professional bibliographer. Nevertheless, these translations provide material for the treatment of several topics not yet fully investigated: the rise and fall of Galen's reputation in the Renaissance; the relative importance attached to his works and their place in the contemporary medical curriculum, the attitude of the scholar-physicians to the task of translation, and their contribution towards the new medical terminology. A necessary task preliminary to any such investigation is the exhaustive listing of printed translations and editions, for the existing bibliographies are far from adequate. It is hoped that the present census, based on the holdings of just under a hundred libraries.
The Tanzawa mountainland consists of a pyroclastic complex chiefly of basic composition which is intruded by a large mass of quartz-diorite at the center. This complex, well-known as the Misaka series, is the products of largescale geosynclinal volcanisms which took place during the period from the latest Oligocene to the middle Miocene in age. As compared with other geologic units, the present complex is characterized by its unusually thick accumulation of pyroclastic rocks, and by the intense hydrothermal alteration of the rocks, furnishing us an excellent section of the so-called green tuff series in the southeastern region of the Fossa Magna. Also the development of the products of interesting metamorphism of the quartz-diorite to the surrounding pyroclastic rocks is a feature uncommon in the other green tuff series of the above region. The crustal movement occurring during the volcanisms, however, make the structure of this complex highly complicate. In addition, the topographically unfavourable condition of this mountainland causes great hindrance to the geological investigation of this complex. Accordingly, the true natures of the complex remain unknown both stratigraphically and petrographically. Since 1948, the writer has been studying on the complex distributed in the eastern region of the Tanzawa massif from the volcano-stratigraphical point of view, some of the results of which have been published as miscellaneous reports. The main scope of this paper is to describe the stratigraphy, petrography, and the tectonic history of this complex. In this paper are also discussed the characteristics of the volcanic activities and the alterations represented by the same complex.
