    Notes: From May to October 1983 the migration of six adult bream was examined by long-term ultrasonic tagging experiments. Two different migration types were observed: diurnal rhythmical migrations between the littoral and pelagic zones, and sporadic locomotions such as spontaneous excursions of several kilometers distance. At night, during their sojourn in the shallow littoral zone, bream feed intensively on benthic organisms; during their stay in the pelagic areas they presumably feed on zooplankton. Sporadic changes of place enable the bream to feed on locally abundant food resources. During the spawning season, migration contributes to successful spawning.

    Description / Table of Contents: Zusammenfassung Seit Juli 1978 wurden 103 Patienten mit inoperablem kleinzelligem Bronchialkarzinom mit der Zytostatikakombination Adriamycin, Cyclophosphamid und Vincristin (ACO) behandelt. Im Stadium „limited disease“ (n=64) erfolgte während des zweiten Chemotherapiekurses eine prophylaktische Schädelbestrahlung, nach dem vierten eine konsolidierende thorakale Bestrahlung. Nach Erreichen einer kompletten Remission erhielten die Patienten prospektiv randomisiert Etoposid oder keine weitere spezifische Therapie. Ein objektives Ansprechen konnte bei 88/100 auswertbaren Patienten erzielt werden. Im Stadium „limited disease“ fanden sich 72%, im Stadium „extensive disease“ nur 33% komplette Remissionen. Im Stadium „limited disease“ betrug die hochgerechnete mediane Überlebenszeit 15,8, im Stadium „extensive disease“ 9,3 Monate (p〈0.005). Es leben noch 29 Patienten, 4 rezidivfrei länger als 24 Monate. Patienten mit kompletter Remission hatten eine statistisch signifikant (p〈0.001) längere Überlebenszeit als Patienten mit geringerem Ansprechen. Regelmäßig traten gastrointestinale und hämatologische Nebenwirkungen auf, drei Patienten starben während der Induktionsphase an Infektionen. Die kurzzeitige Induktionsbehandlung verbesserte jedoch den Krankheitsverlauf subjektiv und objektiv. Bisher ist kein positiver Effekt der zyklischen Etoposid-Gabe nach ACO festzustellen.
    Notes: Summary Since July 1978 one hundred and three consecutive patients with unresectable small cell bronchogenic carcinoma were treated with a combination of doxorubicin, cyclophosphamide and vincristine (ACO). In limited disease patients (64) the second chemotherapy course was followed by prophylactic cranial irradiation, the fourth by irradiation towards primary disease sites. Complete responders were randomised to either receive etoposide or no further maintenance therapy. Objective responses were reached in 88/100 evaluable patients, with 72% of complete remissions in limited-stage disease and 33% in extensive disease, respectively. The actuarial median survival time for limited disease patients was 15.8 months compared to 9.3 months in extensive disease (p〈0.005). 29 of the 100 patients remain still alive, 4 for more than 24 months without disease recurrence. The survival advantage of patients reaching complete remissions relative to those who did not is highly significant (p〈0.001). Acute gastrointestinal and hematological side effects were common, with possibly three drug-related deaths from infections during transient granulocytopenia (mean nadir: 600–900 cells/mm3). The present induction regimen using only four courses of chemotherapy produces high complete remission rates on roentgenography and bronchoscopy and improved survival in the majority of patients. Thus far any effectiveness of etoposide-maintenance therapy following ACO could not be substantiated.

    Notes: Summary In the past 5 years we have investigated 29 patients with symptomatic basilar artery stenoses (14 cases) and occlusions (14) and a patent primitive trigeminal artery with thin-calibered basilar and vertebral arteries (1) using directional continuous-wave Doppler sonography of the vertebral arteries. A total of 19 patients survived, and 17 of them were clinically and sonographically reexamined after 40.4 ± 15.8 months (mean ± SD). Among the 8 patients with basilar stenoses, 6 — with no further transient ischemic attacks (TIAs) in the interval — exhibited an increase in the summed modified Pourcelot indices (relative end-diastolic flow velocities) of the vertebrals by 0.18 ± 0.16; the other 2 showed a decrease by 0.26 each, in 1 case temporally related to a TIA, in the 2nd case without further clinical deterioration. In the 8 survivors with basilar occlusions, 5 remained — by sonographic criteria — unchanged with summed modified Pourcelot indices of the vertebrals of 0.00, while 3 patients exhibited a slight increase in the summed modified Pourcelot indices of 0.13 ± 0.03. While the difference between the outcome of subsets of patients treated with regimens of 30,000–40,000 units heparin/day or phenprocoumon and less radical drugs were statistically not significant, the former regimen appeared clinically more efficacious in preventing further deterioration in approximately two-thirds of the patients affected. Due to the potential recurrence of neurological symptoms, a treatment period with phenprocoumon of 6 months after discharge from hospital appears justified. Due to these therapeutic efforts, approximately half of the patients initially affected survived with no or only a mild neurological deficit. Directional continuous-wave Doppler sonography is, in our opinion, a reliable technique for examining the short- and long-term changes in peripheral vascular resistance.

    Notes: For the first phase-slip center in superconducting whiskers of zinc and zinc-silver alloys the normalized “normal-like length” and “zero-voltage intercept” are plotted as a function of the “pair-breaking parameter,” which ranges between 4 × 103 and 2 × 104. A comparison is made with results from aluminum microbridges and the prediction of the time-dependent Ginzburg-Landau theory.

    Notes: The current-induced breakdown of superconductivity in Zn and Zn-Ag alloy whiskers close to the critical temperature has been investigated. Above the critical current I c the superconductor enters a dissipative state with characteristics showing a regular voltage step structure due to the appearance of phase-slip centers. For short samples there is an influence of the superconducting contacts. Unaffected phase-slip centers are only observed in long samples. For this case the temperature-independent quasiparticle relaxation time is found to be 3.2 × 10−8 sec. For the zero-voltage intercept I 0 a value of 0.56 I c is obtained.

    Description / Table of Contents: Zusammenfassung Als Spätergebnisse 1–16 Jahre nach Desobliteration einer Carotisstenose im Stadium I bleiben 97,8% der Patienten asymptomatisch, nach Korrektur eines Stadium II sind 79,3% völlig beschwerdefrei und 13,0% deutlich gebessert. Nach operativer Behandlung des frischen Schlaganfalls finden sich als Spätergebnis 20% geheilt und 70% gebessert. Im Defektstadium nach durchgemachtem Schlaganfall werden keine weiteren neurologischen Ausfälle beobachtet. Nach Eingriffen an den anderen Aortenbogenästen zeigen sich in 92,5% überzeugende Langzeitergebnisse.
    Notes: Summary Internal carotid endarterectomy is an effective and longlasting means of preventing cerebrovascular accidents. After 1–16 years it was entirely successful in 97.8% of asymptomatic patients; 79.3% of patients with transient ischemic attacks experienced no further symptoms, 13% were improved. In patients with acute stroke 20% were cured, 70% improved, and 10% unchanged. The follow-up of patients with completed stroke yielded no further neurological deficit. The late results 1–14 years after reconstruction of the other supraaortic vessels were good in 92,5% of cases.

    Notes: Summary Uni- or bilateral isolated obstructions of the iliac arteries (type I) or those localized to the aortic bifurcation (type III) are treated by endarterectomy. Diffuse lesions of the aorta and iliac vessels (type II) and aortic occlusions up to the renal arteries (type IV) are corrected by a bifurcation bypass. Between 1959 and 1978, 617 cases were treated by endarterectomy and 555 by bypass grafting. After 1-20 years, 87.7% of the dseobliterated arteries and 88.4% of the bifurcation grafts are patent.

    Notes: Abstract The results of local beta ray radiation of 295 eyes containing a uveal melanoma (including 74 melanomas of the anterior choroid and ciliary body) are presented with special respect to the complications of treatment. The most frequent complications were radiation retinopathy and optic neuropathy. Complications known to occur from other radiation methods, such as dry eye syndrome, loss of cilia, and scleral necrosis, did not occur in our series. The incidence of radiation cataract, as compared to the treatment with60Co plaques, was lower in our series. An average of 700 Gy delivered to the scleral base of the tumor was needed for uveal melanomas which could be destroyed. This radiation dose resulted in a 10% incidence of radiation retinopathy.

    Notes: Abstract Exact identities are derived for a family of models including (a) a domain wall in a random field Ising model (RFIM), and (b) the random anisotropyXY model in the no-vortex approximation. In particular, the second moment of thermal fluctuations is not affected by frozen randomness. It is checked in a one-dimensional model that higher moments are on the contrary strongly enhanced. Thus, thermal fluctuations are strongly non-Gaussian. This reflects excursions between remote potential wells in the phase space. It is shown exactly that the Imry-Ma argument yields a correct evaluation of the field-induced fluctuations for the one-dimensional model.
