    Description / Table of Contents: Zusammenfassung Die vorliegende Arbeit analysiert die bösartigen Tumoren eines großen allgemeinen Sektionsgutes im Hinblick auf die Häufigkeit, Alters- und Geschlechtsverteilung, Lokalisation und histologische Klassifikation. Sie umfaßt einen Zeitraum von 12 Jahren. Die Neubildungen wurden zunächst verschiedenen Organsystemen zugeordnet, dann den einzelnen Organen; schließlich erfolgte bei den wichtigsten Tumoren eine histologische Differenzierung. Von 23 338 Verstorbenen der Jahre 1960–1971 wurden 17 052 obduziert. Die Sektionsquote betrug im Durchschnitt der 12 Jahre 73,1%. Ausgewertet wurden jedoch nur 15 384 Sektionen (65,9%). Insgesamt 4911 bösartige Neubildungen stellten 31,9% der ausgewerteten Fälle dar. Der männliche Anteil übertraf geringgradig mit 2508 (51,1%) den weiblichen Anteil. Über 60% aller bösartigen Neubildungen (BN) fanden wir bei Verstorbenen im Alter von 60–79 Jahren. Beim Vergleich der Zeiträume 1960–1965 und 1966–1971 ergab sich eine Zunahme der malignen Tumoren um 1,7%. Die getrenntgeschlechtliche Auswertung bestätigte dieses Ergebnis jedoch nur bei den Männern, während bei den Frauen nur ein geringfügiger Anstieg zu beobachten war. Die meisten bösartigen Neubildungen mußten dem Verdauungstrakt (26,2%) vor dem Urogenitaltrakt (23,4%) und dem Respirationstrakt (18,7%) zugeordnet werden. Bei den Männern standen allerdings die BN des Respirationstraktes (30,3%) an erster Stelle vor den Malignomen des Verdauungstraktes (27,4%); bei den Frauen fanden sich die meisten BN im Urogenitaltrakt (29,0%). Die BN des Respirationstraktes sind bei den Männern signifikant häufiger als bei den Frauen; beim weiblichen Geschlecht dominieren die Malignome des Urogenitaltraktes und der Hautanhangsgebilde durch die Häufigkeit des Mammacarcinoms. Im Verlauf der 12 Jahre nahmen die BN des Verdauungstraktes bei den Männern im Verhältnis zu der Gesamttumorzahl des untersuchten Obduktionsgutes signifikant ab, während die Malignome des Respirationstraktes und des Urogenitaltraktes beim Vergleich mit der Anzahl der Sektionen signifikant anstiegen. An erster Stelle der bösartigen Neubildungen der einzelnen Organe standen bei den Männern die Tumoren der Bronchien und der Lunge, gefolgt von denen des Magens; bei den Frauen die Tumoren des Uterus vor denen der Mamma und des Magens. Die Auswertung der einzelnen Organe erbrachte bei den Männern eine signifikante Zunahme der BN der Bronchien und der Lungen sowie der Harnblase beim Vergleich mit der Anzahl der Sektionen, bei der Harnblase darüber hinaus auch im Vergleich zur Gesamttumorzahl der Männer. Für die Frauen ergab sich eine signifikante Zunahme der BN des Skeletsystems einschließlich der Hämoblastosen sowie eine signifikante Abnahme der BN des Gehirns nur im Verhältnis zu den Tumorzahlen des weiblichen Geschlechts. Verallgemeinernde Schlüsse sind aus den dargestellten Verhältnissen sicher jedoch nicht zu ziehen, da der untersuchte Zeitraum von 12 Jahren zu klein ist und das Krankengut aus einem sehr begrenzten Einzugsgebiet stammt; zudem können örtliche Veränderungen in der Zusammensetzung der medizinischen Einrichtungen und Krankenstationen das Bild retrospektiv unkontrollierbar beeinflußt haben. Für die histologische Klassifizierung der wichtigsten Tumoren wurden nur die routinemäßig durchgeführten mikroskopischen Untersuchungen herangezogen. Auf eine weitergehende histologische Differenzierung und seltenere Tumorformen wurde der Übersicht wegen verzichtet.
    Notes: Summary The present study taken over a 12-year time period analyzes malignant tumors in a large number of autopsies, with specific consideration of the frequency and location, age and sex group distribution, and histologic classification of the tumors. The tumors were first evaluated in terms of specific organs and organ systems and were then histologically classified. On a total of 23338 subjects who died between the years 1960 and 1971, 17052 autopsies were carried out (73.1%) and only 15384 (65.9%) of these were evaluated for our study. Altogether we located 4911 cases of MT, i.e., 31.9% of the evaluated autopsies. The number of MT in the males slightly exceeded that in the females (2508 [51.1%] MT and 2403 [48.9%] MT, respectively.) We calculated over 60% of the MT to be in the 7th and 8th age groups. By comparing the two time periods (1960–1965 and 1966–1971) we calculated a significant increase in the MT rate by 1.7%. This increase was found mainly to effect the males (the female group showed only a slight increase). The greatest number of MT were located in the digestive system with an MT rate of 26.2%; next came the urogenital system (23.4%) and then the respiratory system (18.7%). The respiratory system took first position of importance in the males with an MT rate of 30.3% followed by the digestive system with 27.4%. The urogenital system dominated in the females with a rate of 29.0%. The rate of MT of the respiratory system was significantly higher in the males. The MT rate in the urogenital system and the skin and adnexa was significantly higher in the females, especially with respect to carcinoma of the mammary glands. As for the males, we observed during the 12-year study period that in relation to the total number of MT, the MT of the digestive system decreased significantly, while significant increases in relation to the evaluated autopsies occurred in the respiratory and urogenital systems. A significant increase in the MT of the bone marrow was calculated in the females, both with respect to the total number of tumors and the evaluated autopsies. The highest organ MT rates were calculated for the bronchi and lungs and stomach in the males while the uterus, mammary glands, and stomach—in this order—showed highest MT rates in the females. Significant increases in the organ MT rates for the males were calculated both in the bronchi and lungs and the urinary bladder, the evaluated autopsies being taken into consideration. Such an increase was also found in the bladder, when compared with the MT. Significant MT increases in the females were calculated in the skeletal system and hemoblastosis with respect to both the evaluated autopsies and the MT while a significant decrease was calculated in the MT of the brain with respect to the number of MT in the females only. The above results cannot be generalized because the time period was too short, the autopsies were only selective, and the area of our observations was rather limited. Apart from these factors, our results were possibly influenced by the establishment of new medical departments in the hospital during the study period. The histologic classification of the important tumors was accomplished by routine microscopic experiments only. In order to obtain a good overall survey no special stains were carried out for the rare tumors. One of our basic aims was to outline these results in diagrams and graphs.

    Notes: Abstract A method is described for the preparation of a tRNA-dependent wheat germ protein-synthesizing system. This system can be supplied with exogenous tRNAs of eukaryotic or prokaryotic origin. In order to obtain maximal aminoacylation of the added tRNAs, the translation assays can be supplemented with homologous aminoacyl-tRNA synthetase preparations. Such a tRNA-dependent wheat germ protein-synthesizing system, which is easy to prepare, can be used not only to translate plant cytoplasmic mRNAs in the presence of added cytoplasmic tRNAs, but also to determine the translation activity of exogenous tRNAs from various sources in the presence of either natural or in vitro synthesized mRNAs.

    Notes: Abstract In chloroplasts, all 61 sense codons are found in chloroplast (cp) DNA sequences coding for proteins. However among the sequenced cp tRNAs or tRNA genes, tRNAs with anticodons complementary to codons CUU/C (Leu), CCU/C (Pro), GCU/C (Ala) and CGC/A/G (Arg) [or CGC/A (Arg) in Marchantia] have not been found. In this paper we show that cp tRNAAla(U*GC), cp tRNAPro(U*GG) and cp tRNAArg(ICG) are able to decode the corresponding four-codon family. In the case of leucine codons CUU/C, we show that ‘U:U and U:C wobble’ mechanisms can operate to allow the reading of these codons by cp tRNALeu (UAm7G).

    Notes: Abstract Bean (Phaseolus vulgaris cv. Saxa) chloroplasts contain two tRNAPhe species, namely tRNAPhe1 and tRNAPhe2. By sequence determination, we show that tRNAPhe2 is identical to the previously sequenced tRNAPhe1 except for two undermodified nucleotides. By reversed-phase chromatography analyses, we demonstrate that the relative amounts of these two chloroplast tRNAsPhe vary during leaf development: in etiolated leaves the undermodified tRNAPhe2 only represents 15% of total chloroplast tRNAPhe, during development and greening it increases to reach 60% in 8-day-old leaves, and it then decreases to 9% in senescing leaves.

    Notes: Abstract Allele and phenotype frequencies for two tetranucleotide STR (short tandem repeat or microsatellite) systems, HUMvWFA31/A and HUMF13A01, were obtained from a sample of approximately 240 unrelated individuals randomly selected from the French Caucasian population. PCR (polymerase chain reaction) products were analysed on 6% polyacrylamide denaturing gels and visualized using fluorescently labelled primers on the automated 373A ABI DNA sequencer (Applied Biosystems Inc.). French Caucasian allele frequencies were compared to other published Caucasian data. Conditions were optimised for the quadruplex PCR amplification of these two STR loci together with the HUMFESFPS and HUMTHOI loci and the quadruplex PCR was also performed on various forensic DNA samples.

    Description / Table of Contents: Zusammenfassung Der Nachweis von Restriktionsfragmentlängen-Polymorphismen (RFLP's) (1) aus DNA, welche von forensischen Proben extrahiert wurden, bleibt häufig unmöglich wegen Verschlechterung, Kontamination des biologischen Materials and extrem geringer Mengen, welche isoliert werden können. Die Polymerase-Kettenreaktion (PCR) ist eine neue und ganz besonders geeignete Methode, um sehr kleine Mengen (10–20 ng) degradierter DNA zu analysieren und zu typisieren (2, 3). DNA-Analysen auf der Ebene weniger Zellen in forensischen Proben wie Blutspuren, Samenspuren, Scheidenabstrichen und Haarwurzeln erscheint nunmehr möglich mit Hilfe der DNA-Amplifikation. Ein PCR-Protokoll (4, 5) wurde adaptiert, um gleichzeitig eine Y-spezifische DNA-Sequenz vom DYZ1-Locus (6) und eine X-spezifische DNA-Sequenz vom DXS424-Locus (7) zu amplifizieren. Das co-amplifizierte y-spezifische DNA-Fragment (102 Bp) und das X-spezifische DNA-Fragment (181-199 Bp) wurden mit einem Ethidiumbromid gefärbten 4% igen Agarosegel sichtbar gemacht. Der männliche oder weibliche Typ der amplifizierten DNA, welche von Blutproben, Blutspuren, Spermaspuren, Vaginalabstrichen, Hirngewebe und 1, 2, 5 oder 10 Haarwurzeln extrahiert worden war, wurde bestimmt.
    Notes: Summary The detection of restriction fragment length polymorphisms (RFLP) (1) in DNA extracted from forensic samples remains impossible in a significant number of cases due to deterioration and contamination of the biological material and the extremely low quantities of DNA isolated. The polymerase chain reaction (PCR) is a recent and particularly convenient method for analysing and typing very small amounts (10–20ng) of degraded human DNA (2, 3). DNA analysis at the level of a few cells present in forensic samples such as bloodstains, semen stains, vaginal swabs and head hair bulbs now appears possible using DNA amplification. A PCR protocol [4, 5] was adapted to simultaneously amplifiy a Y-specific DNA repeat sequence from the DYZ1 locus [6] and an X-specific DNA repeat sequence from the DXS424 locus [7]. The co-amplified Y-specific DNA fragment (102 bp) and X-specific DNA fragments (181–199 bp) were visualized on an ethidium bromide-stained 4% agarose gel. The male or female type of the amplified DNA extracted from blood samples, bloodstains, semen stains, vaginal swabs, brain tissue and 1, 2, 5, or 10 head hair bulbs was determined.

    Notes: Abstract The authors report on the contribution of odontological identification of the flight ALIT 5148 air disaster victims, which occurred on 20th January 1992. The identification procedure was difficult due to large numbers of bodies and mutilations and required the involvement of multidisciplinary teams composed of odontologists, forensic pathologists, radiologists and biologists. The authors set up a simple, discriminant classification which was easy to handle by a multidisciplinary team. Four groups were defined according to the matching characteristics between ante and post mortem data. Perfect matching characteristics between ante and post mortem data were achieved in only 44 cases (Group A). Partial matching characteristics between ante and post mortem data were achieved in 12 cases (Group B). In 29 cases, the insufficiency or absence of odontological data (Group C and D) did not enable the victim to be identified. The results of the investigations showed that the dental examination alone enabled 17 victims to be identified and by including a morphological examination the figure reached 33. By the end of the investigations, 85 of the 87 victims were positively identified. Odontological identification is an essential, accurate and rapid method with allows a body to be identified from its dental characteristics. This anthropometrical method of identification is included with the descriptive and the biological methods. The authors present their experience in performing a formal identification of 44 victims in less than 15 days.
