    Notes: Gelatinization characteristics of laboratory-isolated and commercial corn starch were compared by differential scanning calorimetry (DSC) before and after being annealed at subgelatinization temperatures in excess water. Prior to annealing, commercial corn starch has a relatively narrow gelatinization range, with a peak temperature at 71°C. Starches isolated in the laboratory have wide gelatinization ranges and lower peak temperatures. After annealing, commercial starch showed little change in gelatinization characteristics, whereas laboratory starches all had narrowed gelatinization ranges, higher peak temperatures, and increased gelatinization enthalpy, indicating changes in the internal structure of the starch granules. This demonstrates that the wet-milling process anneals corn starch during the isolation procedure.

    Description / Table of Contents: Zusammenfassung Bei 14 Patienten nach größeren abdominal-chirurgischen Eingriffen bei unkompliziertem postoperativem Verlauf wurden hämodynamische, blutgasanalytische und biochemische Messungen im arteriellen, prähepatischen und posthepatischen Blut durchgeführt. Folgende Parameter sind erfaßt worden: HZV, arterieller Druck; Pfortader- und Lebervenendruck, ZDV; Blutgase und pH; Lactat, Pyruvat und Glucose. Es werden errechnete Mittelwerte aus Messungen am 1. und 2. postoperativen Tag mitgeteilt. Ergebnisse: 1. In der frühen postoperativen Phase ist der Pfortaderdruck nicht erhöht. Es besteht ein niedriger transhepatischer Druckgradient. 2. Die arterio-portale O2-Gehaltdifferenz ist gegenüber der GesamtkörperAVD02 niedrig. 3. Der transhepatische Lactatgradient ist negativ, d. h. die Leber behält in der frühen postoperativen Phase eine Lactat extrahierende Funktion.
    Notes: Summary After major abdominal operations without postoperative complications in 14 patients haemodynamic, blood gas analytical and biochemical estimations were performed in arterial, prehepatic and posthepatic blood. The following parameters were included: cardiac output, arterial pressure, portal and hepatic vein pressure, central venous pressure, blood gases and pH, lactate, pyruvate, and glucose. Median values were calculated from estimations on the 1st and 2nd postoperative day. Results: 1. In the early postoperative phase the portal pressure is not increased. There is a low transhepatic pressure gradient. 2. The arterio-portal O2 content difference is low compared with the whole-body AVDO2. 3. The transhepatic lactate gradient is negative, i.e. the liver retains a lactate-extracting function in the early postoperative phase.

    Description / Table of Contents: Zusammenfassung Resorptive, digestive und endokrine Störungen wurden bei 11 Patienten nach partieller Duodenopankreatektomie untersucht. Die Rekonstruktion des Gastrointestinaltraktes erfolgte immer mit der proximalen Jejunumsehlinge. 1. Bei allen Patienten bestand eine Störung der Fettdigestion; eine leicht eingeschränkte Eiweißdigestion hatten 3 Patienten. 2. Eine Malabsorption kam nur bei einem Patienten zur Beobachtung. 3. Die Insulin- und Gastrinkonzentration im Blut waren infolge Verminderung der BetaZell-und G-Zell-Masse erniedrigt.
    Notes: Summary In 11 patients we investigated digestive, resorptive, and endocrine functions after pancreatico-duodenectomy. In order to improve the nutritional state of the patients after pancreatico-duodenectomy we performed the reconstruction of the upper alimentary tract with particular attention to the proximal jejunum. We observed: 1. unpaired fat digestion in all patients; 2. a slight restriction of protein digestion in 3 patients; 3. diminished gastrin and insulin concentrations in the basal state.

    Description / Table of Contents: Zusammenfassung Bei 52 Risikopatienten (Durchschnittsalter 68 Jahre) warden 60 untere Extremitäten im Stadium III oder IV nach Fontaine durch eine Prothesenimplantation zwischen Art. axillaris and Art. femorahs versorgt. 11 dieser Patienten hatten hohe Aortenverschlüsse. Die rekonstruktiven Standardverfahren waren nicht anwendbar. Ergebnisse: Nach einem Beobachtungszeitraum von 4 Jahren leben heute 31 Patienten, 24 von ihnen haben funktionstüchtige Prothesen and rind in einem Stadium II Fontaine. Bei 13 Patienten wurde der Bypass wegen einer Thrombose bis zu 3 Jahren nach der Implantation erfolgreich revidiert. Die Operationsletalität betrug 9,6%.
    Notes: Summary From May 1970 to April 1974, 52 poor-risk patients with rest pain or gangrene underwent 60 axillary-femoral by-pass operations. Results: After an observation period of four years, 31 patients are alive. Of these, 24 have functioning prostheses and no rest pain. In 13 patients successful reoperations because of graft thrombosis were performed up to 3 years after the implantation. Five patients died within thirty days of the operation.

    Description / Table of Contents: Zusammenfassung Die 59jährige Patientin leidet $${\raise0.5ex\hbox{$\scriptstyle 1$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle 2$}}$$ Jahr nach einer Desobliteration unter Ruheschmerzen. Das Angiogramm zeigt einen Verschluß der A. poplitea und der Abgänge der 3 Unterschenkelarterien; es ist lediglich die A. tib. post ab Unterachenkelmitte dargestellt. Es wurde ein femoro-tibialer Bypass mit einer konservierten Vene, die 2 Wochen vorher bei einer Varicenoperation gewonnen worden war, zusammen mit einem 15 cm langen brauchbarem Rest eigener V. saphena magna auf die A. tib. post. angelegt (April 1970). Die Patientin ist seitdem beschwerdefrei. Die Arteriographie nach 31 Monaten dokumentiert den funktionierenden Bypass.
    Notes: Summary A 59-year-old female patient had a recurrence of pain in the right leg during rest six months after embolectomy (by the Vollmar method). Arteriography revealed that the pophteal artery and its trifurcation were occluded. It was shown that only the posterior tibial artery was patent behind the middle of the lower leg. In April 1970 we performed the femerocrural bypass operation, joining a short piece of autologous V. saphena magna and a portion of the homologous V. magna gained two weeks before at varicectomy to the posterior tibial artery. The patients has been able to walk for unlimited distances for the last 3 years. Angiography 31 months after the operation confirmed that the bypass was patent.

    Description / Table of Contents: Zusammenfassung Die A. fem. sup. ist der am häufigsten von der chronischen Verschlußkrankheit befallene Gefäßabschnitt. Im Spontanverlauf und ähnlich bei konservativer Therapie beträgt die Amputationsquote um 300% und etwa zwei Drittel der Patienten sind nach 10 Jahren noch am Leben. Die Erfolge der rekonstruierenden Methoden sind deutlich besser: Von 189 Patienten mit 280 operierten Extremitäten, waren 56,4% im Stadium III und IV Fontaine. Durch TEA konnten bei einem durchschnittlichen Krankenhausaufenthalt von 33 Tagen 96,7 % der auswertbaren Extremitäten dem Stadium Fontaine 1 oder II zugeordnet werden. Die Frühletalität betrug 10,3%, die Amputationsquote 3,2%. Nach 5 Jahren waren von 179 auswertbaren Extremitäten 95,6% im Stadium I oder II Fontaine, 18,7 % der Patienten waren verstorben und die Amputationsquote betrug 4,9%. Von 42 Rezidivverschlüssen während der Nachuntersuchungsperiode, wurden annähernd 80% erfolgreich revidiert. Probleme der Indikationsstellung und der operativen Taktik werden diskutiert und die Bedeutung der rekonstruierenden Maßnahmen bei Vorliegen von Kombinationsverschlüssen in der Ausflußbahn betont.
    Notes: Summary 56.4 % out of 189 patients with 280 extremities operated had a stage III or IV Fontaine. Following thrombend arterectomy it was possible to classify 96,7 % of the suitable extremities to stage I or II Fontaine at the time of discharge from hospital. The hospital mortality was 10.3 % and the amputation rate 3.2 %. In the late results up to 5 years after reconstruction 95.6 % of 179 suitable extremities could be classified as stage I or II Fontaine. The amputation rate during this period was 4.9 %. The blood flow in nearly 80 % of 42 reoccluded arteries could be restored. The problems of operative indication and different surgical procedures are discussed and finally reconstructioe methods in the presence of additional occlusions in the outflow tract of the superficial femoral artery are pointed out.

    Description / Table of Contents: Zusammenfassung Seit 1966 wurden bei 136 Patienten mit chronischer Verschlußkrank-heit der Unterschenkelarterien 147 Extremitäten operiert. Die Lokalisation und Ausdehnung der Verschlußprozesse im Unterschenkel sowie die hohe Quote von Kombinationsverschlüssen erklären die Tatsache, daß 80% der Patienten amputationsbedrohte Extremitäten im Stadium III und IV hatten. Die angewandten rekonstruktiven Verfahren waren die direkte Desobliteration der Poplitea-Trifurcation oder langstreckige Umgehungen mit dem Vena saphena insitu by pass zu den Popliteasegmenten II und III oder einer der Unterschenkelarterien. Die Letalität bis zur Klinikentlassung betrug 11%, die Amputations-quote 3,4%. Von den verbliebenen 127 auswertbaren Extremitäten waren bei der Klinikentlassung 93,7% funktionstüchtig. Im Spätergebnis bis zu 4 Jahren betrug die Erfolgsquote bei 98 auswertbaren Extremitäten 88,7%. Die günstigen Erfahrungen lassen eine weniger zurückhaltende Einstellung zur Rekonstruktion der A. popl. und der Unterschenkelarterien wünschenswert erscheinen.
    Notes: Summary Since 1966 136 patients with arterial occlusive disease of the popliteal artery and of the lower leg arteries have been operated upon. The site and extenz of the stenoses and occlusions are demonstrated and the classification of the ischemic complaints are shown. The early and late patency rate in the group of 147 extremities operated upon during 1966–1970 are discussed. The hospital mortality is 11%, the amputation rate 3.4%. 93.7% out of 127 suitable extremities proved to be a success. The late patency rate up to 4 years out of 98 suitable cases is 88.7%. Based on their results the authors propose a more aggressive approach in the treatment of arteriosclerotic occlusive disease of the popliteal and lower leg arteries.

    Notes: Summary One hundred forty-nine patients 65–94 years old had a high frequency loss in the pure tone audiogram corresponding to data in literature. There was no significant difference between left and right. The SISI-score and Langenbeck-audiogram showed a cochlear type in 80%. The tests for central speech perception showed correlation to age in the following sequence: Dichotic discrimination, followed by discrimination of one — syllable — words, then hearing loss for words with four syllables, then binaural summation. Other parameters like serum-cholesterin and cardio-vascular function had a correlation to age much less pronounced than the audiological tests.

    Notes: Abstract The local effects of the emission of a solid-fueled rocket on the stratospheric ozone concentration have been investigated by photochemical model calculations. A one-dimensional horizontal model has been applied which calculates the trace gas composition at a single atmospheric altitude spatially resolved around the exhaust plume. Different cases were tested for the emissions of the Space Shuttle concerning the composition of the exhaust and the effects of heterogeneous reactions on atmospheric background aerosol. The strongest depletion of ozone is achieved when a high amount of the emitted chlorine is Cl2. If it is purely HCl, the effect is smallest, though in this case the heterogeneous reactions show their largest influence. From the results it may be estimated whether ozone depletion caused by rocket launches can be detected by satellite instruments. It appears that the chance of coincidental detection of such an event is rather small.
