Histamin in der Interstitialfl�ssigkeit der befallenen und klinisch nicht befallenen Haut bei chronisch rezidivierender Urticaria
Bei 8 Patienten mit idiopathischer chronisch rezidivierender Urticaria wurden in der Periumbilicalregion Saugblasen gleichzeitig auf frischen urticariellen Herden und der unveranderten Haut daneben produziert und Histamin in der Blasenflussigkeit bestimmt. Hierzu wurde die von Siraganian entwickelte Methode der Autoanalyzer-Technik in modifizierter Form verwendet. Die Histaminspiegel lagen bei diesen Patienten in unveranderter Haut in derselben Grosenordnung wie bei 10 Normalpersonen, wahrend alle 8 Urticaria-Patienten hohere Histamin-Werte in den Urticae verglichen mit der nicht befallenen Haut aufwiesen; bei 4 der Patienten waren diese Unterschiede jedoch nur gering ausgepragt.
Electromagnetic transition probabilities in 130Ce
Abstract Lifetimes of excited nuclear states have been measured in 130Ce using the coincidence-plunger technique. The employed nuclear reaction was 98Mo(36S, 4n)130Ce at a beam energy of 150 MeV. The measurement has been performed at the NSF Daresbury using the ESSA 30 set-up. It was possible to determine lifetimes for the 4+ to 16+ states in 130Ce. The experimental B(E2) values could be well reproduced by calculations using the triaxial rotor model with β = 0.26 and γ = 21° as well as the rotation vibration model (β = 0.25).
Seasonal Variations on the Cortisol Concentration of the Subretinal Fluid in Rhegmatogenous Retinal Detachment
Probes of the subretinal fluid were obtained from 115 nonselected retinal detachments, operated on during the period from November 19, 1973 to December 20, 1974. All patients had no known endocrine abnormalities and had not ever received topical or systemic corticosteroid therapy. Subretinal fluid Cortisol was determined by competitive protein binding analysis. A statistically significant increase in mean subretinal fluid Cortisol concentration was found for the winter season (3.3 µg/100 ml), as compared with the summer months (1.5 µg/100 ml). This finding sharply contrasts with the seasonal incidence of the idiopathic retinal detachments which reaches its maximum in the months June to Augu…
