    Description / Table of Contents: Zusammenfassung Die Reaktion von 9-Methyl-10H-dipyrrin-1-onen mit Brom in Dichlormethan ergab in mäßigen Ausbeuten rotgefärbte Gallenfarbstoffderivate. Sie konnten strukturell als 1,2-bis-Dipyrrinon-ethene zugeordnet werden, die ein Beispiel für die bisher unbekanntenb-Homoverdine darstellen. Darüber hinaus konnten aus der Reaktionsmischung die entsprechenden Mesobiliverdine-XIIIα isoliert werden. Die mechanistischen Aspekte dieser Reaktion werden diskutiert.
    Notes: Summary Upon treatment of 9-methyl-10H-dipyrrin-1-ones with bromine in dichloromethane, red bile pigment derivatives were obtained in moderate yields. They were structurally assigned as 1,2-bis-dipyrrinon-9-yl-ethenes, which are examples of the hitherto unknownb-homo-verdins. In addition, the correspondingmeso-biliverdins-XIIIα could be isolated from the reaction mixture. The mechanistic aspects of the reaction are discussed.

    Notes: Abstract A rate case of a very unusual position of a normally functioning spleen in the posterior aspect of the right lobe of the liver is reported. A 6-year-old boy was evaluated with echocardiography for congenital heart disease of coexisting atrial and ventricular septal defects with pulmonary hypertension. Other associated cardiac abnormalities on this child included a right-sided aortic arch, drainage of the azygous vein into the superior vena cava and an Eisenmenger complex. At the time of echocardiography, absence of the spleen in its normal location was noted. This prompted further investigation into localizing the spleen using 99mTc-sulfur colloid and heat denatured 99m-Tc-RBC scintigraphy. Both scans demostrated the spleen to lie posterior to the right hepatic lobe.
