    Notizen: Four sequential polypeptides containing equimolar amounts of tyrosine, glutamic acid, alanine and glycine were shown to be T lymphocyte-dependent immunogens in inbred guinea-pigs. Poly (Glu-Ala-Tyr-Gly) was immunogenic only in strain 2 guinea-pigs; poly (Glu-Tyr-Ala-Gly) and poly (Ala-Tyr-Glu-Gly) were immunogenic only in strain 13 guinea-pigs; and poly (Ala-Glu-Tyr-Gly) was immunogenic in both inbred strains. The specificity of immune recognition was probed at the T lymphocyte and humoral levels with the heterologous polypepties. Only a few cases of heterologous cross-stimulation or cross-reaction were observed, indcating the great selectivity of immune recognition. The results showed considerable variability in immune recognition from animal to animal. Nevertheless, at the T-cell level, cross-stimulation appears to necessitate that the antigen is itself immunogenic in that strain, whereas at the antibody level, cross-reaction is not similarly restricted. The structural basis for mutual recognition of immunogen and antigen at these levels is discussed.

    Notizen: Allophenic mice were produced by aggregating 8-cell embryos from a low responder (CBA) and a high responder (DBA/1) strain to the synthetic amino acid polymer GLø. In some strains of mice, the immune response to this polymer is controlled by two genes, α and β, which map to the IE/C and IA subregions of the H-2 complex, respectively. The CBA strain is α+β - whereas the DBA/1 strain can be considered to be α+β+. These two strains also differ in immunoglobulin allotype: CBA is allotype a and DBA/1 is allotype c. Eight CBA DBA/1 allophenic mice were immunized with GLø. Four of the mice gave a high secondary response to the polymer. The alloptype of the angibody from these mice was determined by affinity chromatography, and it was found that only allotype c was present. This means that all of the antibody was produced by high responder DBA/1 cells. Thus, there is no evidence for the cooperation of histoincompatible cells in the mounting of an immune response by allophenic mice.

    Notizen: Thirty-three patients with histologically verified urticaria pigmentosa were studied for coexisting atopi disease by means of history, skin prick testing with five common inhalants and serological investigation for total IgE and specific IgE antibodies to five common inhalants. The prevalence of atopy in urticaria pigmentosa was similar to that observed m the normal Swiss population, both on the basis of history (7/33 = 21 %) and of positive skin prick tests to common inhalants (12/33 = 36%). However, total serum IgE levels were significantly lower (geometric mean value 16.8 kU/l) than in a control group of 52 Swiss blood donors of comparable age and sex distribution (geometric mean value 43.0 kU/l, 2.93, P 〈 0.005). Specific IgE antibodies to common inhalants were also observed less frequently in urticaria pigmentosa patients than in controls, although this difference was not statistically significant. Low total and specific IgE values in patients with urticaria pigmentosa may be explained by increased absorption of circulating IgE to abundant tissue mast cells.

    Notizen: Abstract We assessed the prevalence of recurrent vasospasm following failure of intra-arterial papaverine and the efficacy of repeat intra-arterial infusions of papaverine for control of recurrent vasospasm. Of 24 patients treated with intra-arterial papaverine for vasospasm following aneurysm surgery, 12 did not improve clinically after the initial treatment; 9 received second or third infusions on consecutive days; 6 received only a second infusion; and 3 received a third. Superselective infusion into the intracranial arteries was performed in all nine cases. Despite angiographic improvement after the initial or second infusions, all nine patients showed varying degrees of recurrent vasospasm at the time of the second or third treatment. Within 24 h of a second infusion, three of the six patients had significant clinical improvement, and one of these showed marked improvement soon after a third infusion. Our preliminary results suggest that repeat papaverine infusion may be a way of controlling recurrent or recalcitrant vasospasm.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung. Die Fehlbeurteilung und unzureichende Wiederherstellung einer initialen oder nach primär alloplastischem Gefäßersatz persistierenden Organischämie bei der akuten thoracoabdominalen Aortendissektion stellt unverändert einen gravierenden Morbiditäts- und Letalitätsfaktor dar. Die abdominale Aortenfensterung stellt ein operatives Verfahren dar, das sich primär an dem morphologischen Substrat der Aortendissektion und der Auswirkung auf die arterielle Perfusion der Abdominalorgane orientiert. Vorgestellt werden 5 konsekutive Patienten (4 Männer, 1 Frau) mit akuter thoracoabdominaler Aortendissektion (2 Typ-A-, 3 Typ-B-Dissektionen) und assoziierter intestinaler, renaler, spinaler und peripherer Organischämie. Anhand einer primären oder sekundären abdominalen Aortenfensterung war es in allen Fällen möglich, ein Organversagen zu verhindern. Im postoperativen Langzeitverlauf sind alle Patienten nach 3 Jahren beschwerdefrei und rehabilitiert. Sekundärkomplikationen traten nicht auf. Wenn nach primärem prothetischen Aortenersatz bei akuter Typ-A- oder Typ-B-Dissektion eine durch arterielle Malperfusion verursachte abdominale Organischämie weiter besteht oder neu auftritt, sollte die abdominale Aortenfensterung sekundär ohne Zeitaufschub erfolgen. Bei akuten Typ-B-Dissektionen muß die Aortenfensterung als primäres Verfahren in Erwägung gezogen werden, wenn ein durch Ischämie bedingtes Organversagen zum prognostisch bestimmenden Faktor wird.
    Notizen: Summary. Intestinal, renal, spinal or peripheral arterial ischemia or failure of branch artery recanalization following initial prosthetic repair of thoracoabdominal aortic dissection is still a problem, with high morbidity and mortality. Five consecutive patients with acute thoracoabdominal aortic dissection (two type A dissections, three type B dissections) suffering from concomitant intestinal, renal, spinal and acute peripheral arterial ischemia are reported. Considering the anatomical and pathophysiological basis of thoracoabdominal aortic dissection and concomitant organ ischemia, the aortic fenestration procedure as a primary or secondary operative approach succeeded in restoring blood flow in all cases without complications. Assessment of the long-term results after 3 years revealed that all patients are doing well without any residual complaints. We conclude that in the case of persistent or secondary onset of aortic branch artery ischemia following initial prosthetic repair of either type A or type B dissection, aortic fenestration can be recommended immediately as a staged operative approach. Primary abdominal aortic fenestration is justified in acute type B dissection when end-organ ischemia becomes the focus of clinical deterioration.
