Nuclear Magnetic Resonance (NMR) ,ddc:530 ,Dewey Decimal Classification::500 | Naturwissenschaften::530 | Physik - Abstract
Nuclear magnetic resonance spectroscopy was used to study polycrystalline β-spodumene (β−LiAlSi2O6) as well as glassy specimens with the same chemical composition. 7Li spin-lattice relaxation measurements were carried out in a broad temperature range and for several Larmor frequencies. In addition to a pronounced rate maximum at high temperatures, stemming from the long-range Li motion in these aluminosilicates, we found a weak maximum in the crystalline modification near 120K. The latter result confirms the existence of a local double-well structure in which the Li ions reside. The ionic motion was also monitored by solid- and stimulated-echo spectra as well as by the decay of the Jeener-Broekaert echo. Under conditions which are discussed in detail, the latter is a direct measure of the hopping correlation function. For the glass this function was found to decay faster and more stretched than that of the crystal at a given temperature. Furthermore, the relevant barriers against the high-temperature long-range Li motion are larger in the crystal as compared to the glass. © 2005 The American Physical Society.

- Abstract
Aim: Determination of the biological effect of the alpha emiter 211At on cellular level as well as the assessment of dosimetric data in a tumor model in vivo. Methods: Transplantation of malignant ascitic cells in mice intraperitoneally and estimation of tumor characteristics (doubling time of the cells, mean survival of the animals following an i.p. applicatin of a defined tumor cell number). 211At labelled human serum albumine microspheres B-20 (MSP) of different activity were injected into tumor bearing mice intraperitoneally. The effectiveness of the therapy was evaluated by means of determination of the duration of cell cycle arrest as well as the microscopic analysis of the rate of abnormal mitotic cells due to radiation induced damage. Furthermore, dose dependence of survival was evaluated. Results: Three days following the intraperitoneally application of 8 x 106 tumor cells, 50 - 600 kBq 211At-MSP were applied into the abdominal cavity. Derived from the volume of ascites at this time and the administered activity, dese calculations were performed. An activity of 50 kBq caused a dose of 0.84 Gy. The increase of radiation induced effect on ascitic tumor cells was correlated with the dose. Between the duration of the cell cycle arrest and the administered activity, a dirctly proportional correlation was found. The mean survival of non treated animals was 16.9 ± 3.7 days. Teh prolongation of the survival was proportional to the activity administered. Using a dosage of 10 Gy, five animals out of 16 survived. Conclusion: Therapy of malignant ascitic cells using 211At-MSP was effective in vivo. For tumor therapy, teh alpha emitter 211At represents a highly effective alternative to usually employed beta emitters.

- Abstract
Ziel: Seit der Einführung von PET in die klinische Anwendung werden 11C markierte Aminosäuren vor allem für die Hirndarstellung verwendet. Im Sinne breiterer Anwendbarkeit wurden Aminosäuren auch mit 18F und 123I markiert. Ausgehend vom Precursor für das 3-O-methyl-6-[18F]fluoro-L-DOPA (OMFD) synthetisierten wir das analoge Iodprodukt OMID, mit dem Ziel die guten Ergebnisse, die im PET erreicht wurden, zukünftig auf das breiter verfügbare SPECT zu übertragen. Methodik: Die stereoselektive Synthese basiert auf der elektrophilen Substitution des entsprechenden zinnorganischen Precursors. Die Markierung wird mit 1 mg Substanz in Acetonitril und N-chlorosuccinimid als Oxidationsmittel innerhalb von 10 min bei Raumtemperatur durchgeführt. Es schließt sich eine Hydrolyse der Schutzgruppen mit konzentrierter HCl bei 80°C und eine Reinigung mittels HPLC (PRP1 Säule, Laufmittel: Ethanol/Phosphatpuffer 70/30) an. Die Bioverteilung wurde nach Injektion von [123I]OMID und [18F]OMFD in Wistarratten verglichen. Ergebnisse: Der [123I]NaI Umsatz zu [123I]OMID erfolgt quantitativ. Nach abschließender Abspaltung der Schutzgruppen und Reinigung wird nach ca. 90 min eine Ausbeute von 50% bezogen auf das eingesetzte Iod erreicht. Das Endprodukt ist in vitro stabil markiert und auch nach Injektion in Wistarratten ist nur eine geringe Iodabspaltung (123I]OMID und [18F]OMFD ähneln sich, wobei nach 1 h die Aufnahme von OMID in Hirn und Muskel geringer ist als die Aufnahme von OMFD. Erste Untersuchungen an tumortragenden (FaDu) Nacktmäusen zeigten eine brauchbare Darstellung der Tumore isb. 10-30 min p.i.. Schlussfolgerung: Das Verfahren zur Herstellung von [123I]OMID ist einfach und ergibt in kurzer Zeit gute Ausbeuten. Die Verwendung von Iod an Stelle von Fluor führt zur Lipophilieerhöhung und zu Unterschieden in der Bioverteilung der markierten Substanzen. Weitere Untersuchungen zur Abschätzung der Potenzen von OMID bei der Tumordarstellung sind notwendig.

Multidisciplinary studies of geotransects across the North European Plain and Southern North Sea, and geological reexamination of the Variscides of the North Bohemian Massif, permit a new 3-D reassessment of the relationships between the principal crustal blocks abutting Baltica along the Trans-European Suture Zone (TESZ). Accretion was in three stages: Cambrian accretion of the Bruno–Silesian, Lysogory and Malopolska terranes; end-Ordovician/early Silurian accretion of Avalonia; and early Carboniferous accretion of the Armorican Terrane Assemblage (ATA). Palaeozoic plume-influenced metabasite geochemistry in the Bohemian Massif explains the progressive rifting away of peri-Gondwanan crustal blocks before their accretion to Baltica. Geophysical data, faunal and provenance information from boreholes, and dated small inliers and cores confirm that Avalonian crust extends beyond the Anglo-Brabant Deformation Belt eastwards to northwest Poland. The location and dip of reflectors along the TESZ and beneath the North European Plain suggest that Avalonian crust overrode the Baltica passive margin, marked by a high-velocity lower crustal layer, on shallowly southwest-dipping thrust planes forming the Heligoland–Pomerania Deformation Belt. The “Variscan orocline” of southwest Poland masks two junctions between the Armorican Terrane Assemblage (ATA) and previously accreted crustal blocks. To the east is a dextrally transpressive contact with the Bruno–Silesian and Malopolska blocks, accreted in the Cambrian, while to the north is a thrust contact with easternmost Avalonia, deeply buried beneath younger sedimentary cover. In the northeast Bohemian and Rhenohercynian Massifs Devonian “early Variscide” deformation dominated by WNW and NW-directed thrusting, records closure of Ordovician–Devonian seaways between detached “islands” of the ATA and Avalonia.

Introduction: The role of positron emission tomography (PET) with 2-[18F]fiuoro-2-deoxy-D-glucose ([18F]FDG) is currently under evaluation in urologic oncology. The aim of the present study was to investigate the use of [18F]FDG positron emission tomography ([18F]FDG-PET) in the detection and treatment control of malignant germ cell tumors compared to computed tomography (CT). Materials and Methods: Thirty-two PET studies and CT scans were carried out in 23 patients with histologically proven germ cell tumors (10 seminomas, 12 non-seminomatous germ cell tumors (NSGCT), 1 unclassified serologic recurrent disease) Lugano stage I-III. The scans were done either after initial diagnosis (n = 21) and/or within 3-45 days after chemotherapy was completed (n = 11). PET and CT were validated either by histology (n = 7) or clinical follow-up of 6-11 months after the last PET study has been performed (n = 16). Sensitivity, specificity, accuracy, positive and negative predictive values were determined for PET and CT. Differences between PET and CT for parameters of diagnostic value were evaluated by chi2 test. Results: Although not statistically significant, the sensitivity, accuracy and negative predictive value were higher for PET than for CT with respect to the detection of metastatic infradiaphragmatic and supradiaphragmatic lesions after initial diagnosis. The specificity and positive predictive value of PET and CT were comparable. After chemotherapy, PET was found to be significantly superior in specificity and accuracy compared to CT with respect to infradiaphragmatic lesions (p < 0.05). False-positive PET findings in supradiaphragmatic lesions after chemotherapy occurred in the case of inflammatory processes and resulted in a loss of specificity and accuracy compared to CT (p < 0.05). Conclusions: These preliminary results demonstrate [18F]FDG-PET to be a useful diagnostic tool for the initial staging and treatment control in patients with germ cell tumors. Possible advantages compared to CT, however, are as yet not clearly defined. The possibility of false-positive PET findings due to reactive supradiaphragmatic inflammatory processes early after chemotherapy have to be considered.

The incidence of malignant melanoma has been continuously increasing over the last few decades. Non-plantar melanomas are nowadays usually diagnosed and treated surgically at an early stage. In contrast, melanoma in a plantar location is usually diagnosed at an advanced tumour stage, conferring a poor prognosis. To discover the reasons for this remarkable difference in recognition and prognosis, we analysed our cases of plantar malignant melanoma in a retrospective study. From 1990 to 1997, we treated 925 melanoma patients. Of these, 68 cases (7%) were classified as plantar melanoma. For non-plantar melanoma patients the mean age was 52.6 years, the mean Clark level was 2.8 and the mean tumour depth was 1.22 mm. In contrast, the mean age of patients with plantar melanoma was 63.3 years, the mean Clark level was 3.61 and the mean tumour depth was 2.55 mm. The mean time between the first observation of the plantar skin lesion and the first consultation with a physician (patients' delay) was 4.8 years and, on average, it took an additional 7 months before adequate surgical treatment was performed (physicians' delay). The prognosis of our patients was poor. In 98.5% (n = 67) further metastases were observed on follow-up. Since there is still no cure for advanced plantar malignant melanoma, the early detection and subsequent surgical treatment of plantar melanoma is decisive for the prognosis. Based on our results, the poor survival can be improved by a significant reduction in the time period between the first observation of a plantar skin lesion and surgical treatment. Therefore there is an urgent need for special preventive health care campaigns to reduce significantly both the patients' and the physicians' delay.

The prognostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the assessment of post-treatment residual masses in patients with Hodgkin's disease (HD) or non-Hodgkin's lymphomas (NHL) was evaluated. We prospectively studies 58 patients with HD (n = 43) or NHL (n = 15) who had post-therapeutic complete remission with residual masses (CRu) indicated by computerized tomography. Analysis of 62 residual locations by FDG-PET was performed separately for HD and NHL. Patients with a PET-positive residual mass [standardized uptake value (SUV) > 3] had a recurrence rate of 62.5% (5/8 patients), whereas patients with PET-negative residual mass (SUV -< 3.0) showed a recurrence rate of 4% (2/50 patients, P = 0.004). A positive FDG-PET study correlated with a significantly poorer progression-free survival (P < 0.00001). No recurrence occurred in any of the 39 HD patients with negative PET scan (negative predictive value, 100%). Four out of four NHL patients with a positive PET study relapsed (positive predictive value, 100%). In conclusion, FDG-PET is a suitable non-invasive method with a high degree of accuracy in the prediction of early recurrence in lymphoma patients with CRu.

- Abstract
Ziel: Entwicklung einer synthetischen Aminosäure als Tracer zur Tumordiagnostik. Synthese, biologische Evaluierung und erste Anwendung am Menschen von 18F-markierten OMFD. Methode: Für die Synthese des [18F]OMFD wurde ein neuer Precursor entwickelt (n-Formyl-3-O-Methyl-4-O-Boc-6-trimethylstannyl-L-DOPA-ethyl-ester), der eine hohe Ausbeute bei relativ kurzer Synthesedauer ermöglicht. Die biologische Evaluierung erfolgte an Zellkulturen (HT-29;RBE-4) und tumortragenden Nacktmäusen (PE-Ca). Erste klinische Ergebnisse wurden bei 3 Patienten mit Glioblastoma multiforme erhoben, die bereits z.T. mehrfach voroperiert und bestrahlt worden waren. Zur Planung einer stereotaktischen Hirnbestrahlung bei klinischem V.a. Rezidiv und inkonklusiven Ergebnissen in der übrigen bildgebenden Diagnostik wurde ein Aminosäure-PET zur weiteren Abklärung durchgeführt. Nach Injektion von 330 MBq [18F]OMFD wurde eine dynamische Sequenz über 90 min und eine Aufnahme des Körperstammes durchgeführt. Ergebnisse: Synthese: Die Ausbeute mit dem neuen Precursor beträgt 20-25% in 50 min Synthesezeit. Zellkultur: In vitro zeigte sich eine hohe Traceraufnahme in die Tumorzellen über den L-Transporter ohne Nachweis einer Metabolisierung oder Proteininkorporation. Tiermodell: Biodistributionsdaten zeigten eine hohe Tumoraufnahme (12,4±1,8%ID/g) mit hohem Tumor/Blut-Verhältnis (45 min p.i.: 9,2±0,8). Patienten: Bei allen Patienten ließ sich im Gebiet des vermuteten Tumorrezidivs mit [18F]OMFD eine fokal erhöhte Traceraufnahme darstellen. Das Verhältnis von Tumor zu Nicht-Tumor betrug 2,2±0,5. Die maximale Traceraufnahme wurde zw. 12 min und 25 min p.i. beobachtet. Im Körperstamm zeigte sich nur eine sehr geringe Traceraufnahme in der Muskulatur, im Thorax und dem Abdomen. Schlussfolgerung: Die in vivo- und in vitro-Experimente haben gezeigt, dass [18F]OMFD als synthetische Aminosäure in Tumoren angereichert wird. Die ersten diagnostischen Anwendungen an Patienten zeigten ermutigende Ergebnisse in der Lokalisation von Rezidivtumoren beim Glioblastom.

- Abstract
Ziel: Zahlreiche Studien in den letzten Jahren belegen den Stellenwert der intraarteriellen Radioembolisation maligner Tumoren. Bisher sind aber in Europa keine mit einem Betastrahler kurzer Halbwertszeit markierte Mikrosphären kommerziell verfügbar. Nach erfolgreicher Markierung verschiedener, metabolisierbarer und nicht metabolisierbarer Partikel mit 188Re (T1/2=17h) in hoher Ausbeute wurde die Biokinetik von Humanserumalbuminmikrosphären (HSAM) mit einem Durchmesser von 25 µm hinsichtlich Belastung der Normalgewebe untersucht. Methodik: Für die Markierung wurden ca. 370 MBq 188Re Generatoreluat (2 ml) mit 6 mg Gentisinsäure, 7,5 mg SnCl2 2H2O und 0,5-5 mg der HSAM gemischt und für 1 h bei 100 °C in einer Glasampulle erwärmt. Nach Entfernung des Überstandes durch Zentrifugation und zweimaliges Waschen erfolgte die Resuspension in NaCl-Lösung und Röntgenkontrastmittel. Zur Untersuchung der Biokinetik wurden nachi.v. Injektion Wistarratten nach 20 min, 4 h, 24 h, 48 h und 96 h getötet. Proben verschiedener Organe sowie von Blut, Urin und Faeces entnommen und der Radioaktivitätsgehalt gemessen (vgl. Tab.). Die Lunge diente dabei als Modell eines gut perfundierten Tumors. Ergebnisse: Obwohl es sich bei den 188Re-HSAM um biologisch abbaubare Partikel handelt, belegen unsere Ergebnisse die gute in-vivo-Stabilität mit geringer Anreicherung in den Normalgeweben bis 96 h p.i. Die Dosisberechnung nach MIRD-Modell mit dem PC-Programm Mirdose 3.1 zeigen, ausgehend von den experimentellen Daten, die Niere als kritisches Organ mit einer Belastung von 0,26 mGy/MBq. Schlussfolgerungen: Da mehr als 100 GBq der 188Re-HSAM appliziert werden müssten, um die TD5/5 der Niere zu erreichen, erscheinen die bereits für die Lungenperfusionsszintigraphie zugelassenen Mikrosphären hinsichtlich der Anwendung am Menschen als sicher.

- Abstract
OBJECTIVES: Development (synthesis, biologic evaluation and first results in humans) of a [18F]-labeled synthetic amino acid for tumor detection with PET. METHODS: Synthesis of [18F]OMFD based on a new precursor (N-formyl-3-O-methyl-4-O-Boc-6-trimethylstannyl-L-DOPA-ethyl-ester). The biologic evaluation was performed in cell culture (HT-29;RBE-4) and tumor bearing nude mice (SC-Ca). First application in humans were obtained in 4 patients with recurrent glioblastoma multiforme with inconclusive CT and MRI. [18F]OMFD was used to identify localization and extent of recurrent tumor for treatment planning with stereotactic radiotherapy, which was the last treatment option for the individual patient. RESULTS: The radiochemical yield of [18F]OMFD was 20-25% (decay corrected, related to [18F]F2) in 50 min synthesis time. Cell culture experiments showed a high tracer uptake in tumor cells via the L-amino acid transporter without evidence for any metabolism or protein incorporation. Biodistribution in mice 60 min p.i. showed a high tumor uptake (12.4 ± 1.8%ID/g) with a high tumor/blood ratio (9.2 ± 0.845 min p.i.). In all patients an increased tracer uptake in the area of the suspected recurrence (lesion to non-lesion 2.2 ± 0.5) was found. In the whole body scan only little tracer uptake was observed in the muscles, thorax and abdomen. CONCLUSION: In vitro and in vivo experiments showed increased [18F]OMFD uptake in tumor tissue. The results of preliminary diagnostic studies with [18F]OMFD in patients with glioblastoma multiforme indicate its potential for tumor imaging.

- Abstract
Adults of the triatomine bug Triatoma brasiliensis release 2,2,4-triethyl-5-methyl-1,3-dioxolane (1) as a mixture of the (4S,5S)- and (4R,5R)-enantiomers in a ratio of 4:1. Among the volatile acetals identified from insects so far, this is the first example resulting from an intermolecular condensation of a carbonyl moiety and a diol substructure.

- Abstract
Background: Patients with multiple serrated polyps are at an increased risk for developing colorectal cancer (CRC). Recent reports have linked cigarette smoking with the subset of CRC that develops from serrated polyps. The aim of this work therefore was to investigate the association between smoking and the risk of CRC in high-risk genetics clinic patients presenting with multiple serrated polyps. Methods and Findings: We identified 151 Caucasian individuals with multiple serrated polyps including at least 5 outside the rectum, and classified patients into non-smokers, current or former smokers at the time of initial diagnosis of polyposis. Cases were individuals with multiple serrated polyps who presented with CRC. Controls were individuals with multiple serrated polyps and no CRC. Multivariate logistic regression was performed to estimate associations between smoking and CRC with adjustment for age at first presentation, sex and co-existing traditional adenomas, a feature that has been consistently linked with CRC risk in patients with multiple serrated polyps. CRC was present in 56 (37%) individuals at presentation. Patients with at least one adenoma were 4 times more likely to present with CRC compared with patients without adenomas (OR = 4.09; 95%CI 1.27 to 13.14; P = 0.02). For females, the odds of CRC decreased by 90% in current smokers as compared to never smokers (OR = 0.10; 95%CI 0.02 to 0.47; P =0.004) after adjusting for age and adenomas. For males, there was no relationship between current smoking and CRC. There was no statistical evidence of an association between former smoking and CRC for both sexes. Conclusion: A decreased odds for CRC was identified in females with multiple serrated polyps who currently smoke, independent of age and the presence of a traditional adenoma. Investigations into the biological basis for these observations could lead to non-smoking-related therapies being developed to decrease the risk of CRC and colectomy in these pati

- Abstract
Die hohe diagnostische Treffsicherheit von 18F-FDG erfordert für die breite klinische Anwendung eine leichte Verfügbarkeit der Methode. Die Koinzidenzkameratechnik bietet möglicherweise eine Alternative zu dediziertem PET. Unsere Untersuchung soll im intraindividuellen Vergleich der Befunde die klinische Relevanz der Unterschiede der Meßmethoden analysieren. METHODIK: Untersucht wurden 20 Patienten mit differenziertem Schilddrüsenkarzinom ( 5 papilläre, 15 follikuläre; pT2-4) nach Thyreoidektomie und Radiojodablation. Zum Zeitpunkt der Diagnosestellung waren bei 8 Patienten Lymphknoten-/Fernmetastasen bekannt. Vor der Untersuchung wurde eine 12-stündige Nahrungskarenz eingehalten. Die Untersuchung erfolgte 60 min nach Injektion von 300 MBq 18F-FDG mit einem dedizierten PET-System (ECAT EXACT HR+) sowie 4 h nach Applikation mit einer Koinzidenzkamera (Solus EPIC). Für den Vergleich der Verfahren wurden jeweils die nicht schwächungskorrigierten Daten herangezogen. Bei allen Patienten lag im zeitlichen Abstand von 4 d bis 2 Monaten eine 131I Ganzkörperszintigraphie vor Ergebnisse:......Koinzidenz..........PET..............131I ---------------------------------------------------------------------------------- Hals....................15.....................26..................4 Thorax.................32.....................55................18 Skelett..................3.......................5..................6 Gesamtzahl.........50.....................86................38 Die 86 mit PET nachgewiesenen Läsionen waren mit der Koinzidenzkamera zu 27% gleich gut, zu 31% schlechter erkennbar. In 42% der Fälle war eine Detektion mit der Koinzidenztechnik nicht möglich. In Abhängigkeit von der Läsionsgröße bestand eine 94%-ige Übereinstimmung beider Verfahren oberhalb 1,5 cm und eine 64%-ige Übereinstimmung im Bereich von 1-1,5 cm. Die mit PET nachgewiesenen Läsionen unter 1 cm waren mit der Koinzidenzkamera nicht erkennbar. Hinsichtlich des klinischen Staging wurde mit der Koinzidenztechnik bei 13 Patienten der gleiche Lymphknotenstatus und bei 18 Patienten der gleiche Metastasenstatus wie mit PET ermittelt. 5 Patienten wurden auf Grund kontralateralen Lymphknotenbefalls, der nur mit PET nachweisbar war, zu niedrig eingestuft. Bei je 2 Patienten war eine richtige Einstufung des Lymphknoten- und Metastasenstadiums mit der Koinzidenzkamera nicht möglich.

- Abstract
Ziel der Untersuchung war es, das Ausmaß der Hirnschädigung bei Patienten mit apallischem Syndrom mittels 18F-FDG-PET und 99mTc-ECD-SPECT näher zu charakterisieren. Methodik: Es wurden 16 Patienten (3 Frauen, 13 Männer, Alter 18-67 Jahre, Median 47,5 Jahre) mit apallischem Syndrom untersucht. Die Hirnschädigung bestand zum Zeitpunkt der Untersuchungen zwischen 2,5 und 11 Monate. Bei allen Patienten wurde die regionale Hirnperfusion nach Injektion von 750 MBq 99mTc-ECD in SPECT-Technik, die regionale Glukoseverbrauchsrate nach Injektion von 300 MBq 18F-FDG mit der PET (Siemens ECAT EXACT HR+) bestimmt. Eine quantitative Auswertung war bei 12 Patienten möglich. Ergebnisse: Alle Patienten zeigten ausgedehnte starke Verminderungen der regionalen cerebralen Perfusion wie auch des regionalen Glukosestoffwechsels korrespondierend zur klinischen Symptomatik. Das Ventrikelsystem war bei allen erweitert. Die mittleren Glukoseverbrauchswerte für die graue Substanz waren bei 9 Patienten mit Werten zwischen 11 und 19 µmol/100ml/min stark vermindert, bei 3 Patienten fanden sich noch Werte von 20-22 µmol/100ml/min. Bei 6/14 Patienten zeigten sich Regionen mit relativ gut erhaltener Perfusion, die aber nur noch einen geringfügigen Glukosestoffwechsel aufwiesen. Schlußfolgerung: Die neuronale Aktivität fand sich auch in primär nicht geschädigten Regionen deutlich vermindert. Die Perfusionsmessung mit der SPECT überschätzt die Intaktheit der neuronalen Integrität. Prognostische Parameter sind erst durch den weiteren klinischen Verlauf zu definieren.

- Abstract
Neben klinischen Symptomen wie Muskelschwäche, erhöhte Schlafneigung und geistige Beeinträchtigung wurden bei HMD auch das Vorkommen von Glukoseutilisationsstörungen beschrieben. Da die zerebralen Symptome mit Hirnstoffwechselstörungen gekoppelt sein können, war es das Ziel der Studie, nähere Informationen zur Beeinträchtigung der zerebralen MRGIu und in Verbindung mit der Hirnperfusion zu gewinnen. Methodik: Bei 8 Frauen und 3 Männern im Alter von 27 bis 57 Jahren (Median: 41 Jahre) mit gesicherter Diagnose erfolgten Untersuchungen mit [F-18]FDG-PET (Positome IIIp; 185 MBq iv) und [Tc-99m]-HMPAO-SPECT (Dreikopfkamera, Fanbeam-Kollimatoren, 750 MBq iv.). Die PET-Untersuchungstechnik war limitiert durch das seinerzeit einsetzbare Equipment. Die Quantifizierung erfolgte auf zwei transaxialen PET-Schnitten: Eine Ebene auf Höhe der Basalganglien (BG) und Thalamus (Thal) sowie in einer 3 cm kranialwärts gelegenen Ebene.Unter Verwendung der Sokoloff-Beziehung wurde die Quantifizierung des Glukosemetabolismus in Gesamthirn sowie in zirkulär eingezeichneten Einzelregionen (Graue Substanz: frontaler, temporaler, parietaler Kortex, BG, Thal; weiße Hirnsubstanz) vorgenommen. Die semiquantitative Bestimmung der regionalen Hirnperfusion in SPECT-Schnitten korrespondierend zu den PET-Schnitten wurde für jeweils 12 Regionen pro Schnittebene unter Verwendung einer halbautomatischen Software durchgeführt. 9/11 Patienten ließen im PET, 10/11 Patienten im SPECT keine sicheren Links-Rechts-Differenzen erkennen. In den übrigen Fällen war die Asymmetrie nur angedeutet. Analog dazu fand sich keine distinkte Abweichung der MRGIu zwischen den selektiv untersuchten Hirnregionen und lediglich einmal eine geringfügige Abweichung der regionalen Perfusion vom Mittelwert. Unter Zugrundelegung eines MRGIu Normalwertes für die graue Substanz von 30-35µmol/m100ml/min bei der angewendeten Technik fand sich eine breite interindividuelle Streuung (in µmol(m100ml/min: > 29:4 Patienten, 26-28:3 Patienten, 23-25:3 Patienten, 18:1 Patienten). Ein Patient zeigte somit eine erhebliche Verminderung des Glukosemetabolismus. Für die weiße Substanz, deren Wert für 2 Patienten zwischen 14 und 17, für 7 zwischen 10 bis 13 lagen ergab sich in 2 Fällen mit Werten von < 10 eine deutliche Erniedrigung des MRGIu. Zusammenfassung und Schlußfolgerung: Hervorstechendes Merkmal der untersuchten HMD-Patientengruppe war die Heterogenität der MRGIu bei Gleichförmigkeit der Hirndurchblutung. Beeinträchtigungen des Hirnstoffwechsels f anden sich oft. Die klinisch-neurologische Bedeutung dieser Befunde muß u.a. durch Verlaufsstudien evaluiert werden.

- Abstract
99mTc labelled nucleobases are expected to be precursors for in vivo radioactive labelling of DNA. This offers the possibility for visualization of tumours developing in surroundings of non-dividing tissue as e.g. brain. The aim of the study was achieve uptake of 99mTc complexes of derivatized nucleic acid precursors, especially mercaptoamide functionalized uracil derivatives, into proliferating cells. The 99mTc complexes were prepared by ligand exchange on 99mTc(V) gluconate both as mixed ligand complexes according to the "3+1 principle" and as complexes formed by (MAG)n chelators coupled to nucleobases. Uptake of 7 selected compounds into the crude cytosolic and nuclear fractions of cultured V79 cells was checked. Pulse labelling for 4 hrs showed cellular uptake of some compounds. Best results were about 20% cellular uptake, and thereof up to 40% in the nuclear fraction. The corresponding results with 3HTdR controls were 20% and 75% respectively. Postincubation experiments showed an increase of the percent 99mTc radioactivity in the nuclear fraction by a factor of 2. This means integration of the complex in the nucleus from the pool present in the cytosol after the initial incubation. No radioactivity was released into the postincubation medium. The results are encouraging, making evident that complex compounds of this kind can be taken up into the cell nucleus.

- Abstract
Purpose: The diagnostic role of positron emission tomography (PET) with 2-deoxy-2-[18F]fluoro-D-glucose (FDG) in squamous cell carcinoma of the oral cavity is evaluated. Procedures: In 38 patients, the results of FDG-PET, magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound were compared. The standard uptake values (SUV) of FDG-PET were correlated to histopathological grading and DNA-image cytometry. Results: In the case of lymph node metastases, the sensitivity of FDG-PET (93%) was higher than the sensitivity for the compared methods. The specificity was best for CT. SUVs of diploid tumor cell lines seemed to be lower than in non-diploid tumor cell lines. Conclusions: The high sensitivity and the high negative predictive value of PET may lead to more restrictive therapeutic regimens regarding lymph. node metastases. Studies are necessary regarding possible relationships between glucose metabolism and tumor grading.
