    Notes: Abstract Envelope preparations of chemotrophically and phototrophically grown Rhodospirillum tenue were isolated and characterized on the basis of their contents and composition in phospholipids and fatty acids, as well as on the basis of their enzyme activities, absorption spectra and polypeptide patterns. Both preparations were similar in their contents in phospholipids and fatty acids. Their total fatty acids were characterized by a rather high percentage of saturated fatty acids. The activities of the respiratory reactions were considerably higher in chemotrophic than in phototrophic membranes. This is true especially for activities of the terminal oxidase which were over 20 times greater. The affinities of the corresponding enzymes to their respective substrates (K m ) differed with differences in the culture conditions. Under chemotrophic conditions the K m values for the NADH-dependent reactions were lower than those values under phototrophic conditions, whereas the K m values for the succinate dependent reactions were higher. The low temperature (77°K) near infrared spectrum of the phototrophic membrane showed a peak at 875 nm which was not detectable in the chemotrophic membrane. The polypeptide patterns, in the presence of sodium dodecyl sulfate, of both preparations were quite similar except for the presence of two low molecular weight proteins (M. Wt. 12,000 and 10,000) in the phototrophic membrane which were absent in the chemotrophic membrane. Both envelope preparations were further fractionated into enriched cytoplasmic membrane and outer membrane fractions which were identified on the basis of their contents in 2-keto-3-deoxyoctonate, ubiquinone 8 and bacteriochlorophyll (in the case of the phototrophic membrane) and their enzyme activities. The buoyant densities of the corresponding fractions from both envelope preparations were found to be equal. The data presented in this paper demonstrate that envelope preparations of chemotrophically and phototrophically grown R. tenue are similar in their contents in 2-keto-3-deoxyoctonate, ubiquinone 8, phospholipids and fatty acids, yet differ significantly in their spectra, protein patterns and enzyme activities.

    Notes: Abstract In the course of systematic investigations on low-molecular-weight compounds from the venom of Crotalidae and Viperidae, we have isolated and characterized at least three bradykinin-potentiating peptides (BPP-II, BPP-III, and BPP-V) from Bothrops neuwiedi venom by gel filtration on Sephadex G-25 M, Sephadex G-10 followed by HPLC. The peptides showed bradykinin-potentiating action on isolated guinea-pig ileum, for which the BPP-V was more active than of BPP-II, and BPP-III, rat arterial blood pressure, and a relevant angiotensin-converting enzyme (ACE) competitive inhibiting activity. The kinetic studies showed a K i of the order of 9.7 × 10−3 μM to BPP-II, 7 × 10−3 μM to BPP-III, and 3.3 ×10−3 μM to BPP-V. The amino acid sequence of the BPP-III has been determined to be pGlu-Gly-Gly-Trp-Pro-Arg-Pro-Gly-Pro-Glu-Ile-Pro-Pro, and the amino acid compositions of the BPP-II and BPP-V by amino acid analysis were 2Glu-2Gly-1Arg-4Pro-lIle and 2Glu-2Gly-lSer-3Pro-2Val-Ille, with molecular weight of 1372, 1046, and 1078, respectively.

    Description / Table of Contents: Zusammenfassung Der M. Dupuytren ist eine chronisch progrediente Fibromatose der Palmaraponeurose und der Digitalfascien unbekannter Genese mit einer Morbidität von 1–3%. Der beste Zeitpunkt für die Operation ist gegeben, wenn die Summe der Streckdefizite an einem Finger 20–30° nicht überschreitet. Die Methode der Wahl ist die komplette Entfernung der Palmaraponeurose und der erkrankten Digitalfascien. Bei fortgeschrittenen Kontrakturen an den Fingern sind evtl. Z-Plastiken, freie Hauttransplantationen and Eingriffe an Bändern and Gelenkkapseln erforderlich. Ein Modell der Dokumentation zur Qualitätssicherung wird vorgestellt.
    Notes: Summary Dupuytren's contracture is a chronic and progressive fibromatosis of the palmar aponeurosis and digital fascia. Morbidity is about 1%-3% and the cause is not yet known. The best time for prophylactic surgery is when the degree of deformity has reached a finger flexion of 20°–30°. Complete fasciectomy and excision of the involved digital fascia is the best method. If there is severe extension of contracture, Z-plasties, full-thickness grafts, or operation at the articular capsules or ligaments may be necessary. A documentation model and control of the surgical success are demonstrated.

    Description / Table of Contents: Zusammenfassung Spätfolgen der Verbrennungen der Hände lassen sich je nach Ausdehnung und Mitbeteiligung tieferer Strukturen je nach ihrer Schwere in 4 Typen einteilen. Von 88 operierten Händen gehörten 43% zu Typ I, 28% zu Typ 11, 25% zu Typ III und 4% zum mutilierenden Typ IV. Klinische Beispiele des I. Grades, bei dem alleinige Eingriffe an der Haut zur Funktionswiederherstellung führen und des III. Grades, bei dem wiederholte Eingriffe an Streckaponeurosen, Sehnen, Bändern und Gelenken eine Besserung erreichen lassen, werden vorgestellt.
    Notes: Summary Late consequences of burns of the hands can be divided into four types depending on their extent and the involvement of the underlying tissue structures. Of 88 hands operated on, 43% were Type I, 28% were type II, 25% were type III, and only 4% belonged to the mutilating type IV. Clinical examples of types I and III are shown. Type I requires operation on the skin only to restore full function of the hand, whereas type III also needs repeated surgical treatment of the dorsal apparatus, tendons, ligaments and joints to improve hand movement.
