    Description / Table of Contents: Zusammenfassung Die Blutgruppenaktivitäten in humanen Systemen auf den Erythrozyten dreier Schimpansen wurden individuell untersucht mittels kommerziell erwerbbarer monoklonaler Antikörper (Maus IgM, Anti-A,-B, -H, -M, -N, -Lea und -Leb) sowie mittels Lektine (UEA-I und VGA) und polyklonaler Anti-Seren zur Typisierung der Systemen ABO, MN, Lewis, Rh-Hr, P, Kell, Kidd, Duffy und Lutheran. Die Antigene MN wurden durch Behandlung der Erythrozyten mit den Enzymen Sialidase, Trypsin und Chymotrypsin ausführlich untersucht. Die Blutgruppenaktivitäten A, H, M, N, Leb, c, S, k und Jka wurden unter den drei Schimpansen nachgewiesen. Das Antigen A der Schimpansen-Zellen zeigte die gleiche serologische Aktivität wie das humane A1. Die A-positiven Schimpansen-Zellen hatten höhere H-Aktivität als humane A1 Zellen. Die Lewis-Aktivitäten konnten durch die Absorption-Elutions-Methode nachgewiesen werden. Die Schimpansen-Zellen zeigten positive Reaktionen mit den polyklonalen Anti-M Seren; die ‘M’ Aktivität wurde durch die Sialidase- bzw. Trypsin-Behandlung reduziert. Aber die Zellen konnten auf den monoklonalen Anti-M nicht reagieren. Die Erythrozyten von zwei Schimpansen wurden mit dem monoklonalen Anti-N agglutiniert; die ‘N’ Aktivität wurde durch die Sialidase- bzw. Chymotrypsin-Behandlung reduziert. Aus diesen Befunden ergab sich, daß die Glykophorine und MN Antigene von Menschen und Schimpansen sich strukturell unterscheiden.
    Notes: Summary Human-type blood group activities on the red blood cells (RBCs) of three chimpanzees were individually examined with commercial mouse monoclonal antibodies (anti-A, -B, -H, -M, -N, -Lea, and -Leb) as well as lectins (UEA-I and VGA) and conventional polyclonal antisera for the systems ABO, MN, Lewis, Rh-Hr, P, Kell, Kidd, Duffy, and Lutheran. For further analysis of the MN antigens, treatment of the RBCs with sialidase, trypsin, and chymotrypsin were employed. The activities recognized among the three chimpanzees were A, H, M, N, Leb, c, S, k, and Jka. The RBCs of the three individuals possessed the A antigen which showed the same serologic activity as the human A1. Those chimpanzee RBCs showed higher Hactivity than the human A1 RBCs. The Lewis b activity was revealed by the absorption-elution method. The RBCs of the three individuals showed a reactivity to the polyclonal anti-M reagents, which was affected by both the sialidase and trypsin treatment. The RBCs of two individuals were agglutinated with the monoclonal anti-N. The receptor was sensitive to sialidase and chymotrypsin. The RBCs of the three individuals, however, did not react with the monoclonal anti-M or with one of the polyclonal anti-N. These results indicate structural differences in the glycophorins and MN antigens between the human and chimpanzee.

    Notes: Abstract This study investigated whether prostaglandin E1 (PGE1) could reduce hepatic injury to the liver graft caused by harvesting and 24-h preservation in University of Wisconsin (UW) solution in a canine model. The PGE1-treated group was intravenously administered 0.5 μg/kg per minute of PGE1 for 30 min before harvesting, as well as a concentration of 1 mg/l PGE1 in the washout and UW solutions. In both the PGE1-treated and the control group, all recipients survived for 1 week or more after transplantation. Arterial ketone body ratio (AKBR) remained over 1.0 in the early postoperative period. The PGE1 group showed significant reductions in guanase, GOT, and LDH during the early postoperative period compared to the untreated control group. Histological examination disclosed partial mitochondrial swelling, hepatocyte vacuolation, and necrosis in the control group, while such abnormalities were rarely seen in the PGE1 group. These results suggest that PGE1 can effectively reduce hepatic injury to liver grafts preserved in UW solution prior to transplantation.

    Description / Table of Contents: Zusammenfassung Die Dampfraumanalyse (Headspace-Technik) zur Analyse von Alkohol und Schnüffelstoffen fand bisher allgemeine Anerkennung und weite Verbreitung. Die Impulserhitzungsmethode ist durch die Vorteile gekennzeichnet, daß sie eine Analyse mit äußerst kleinen Proben (1 μl) erlaubt, keine Vorbehandlung erfordert, die Meßzeit verhältnismäßig kurz ist und exakte Meßergebnisse erhalten werden. Sie erlaubt eine Trennung und Identifizierung von flüchtigen Substanzen innerhalb von 15 Minuten im Blut und Urin ohne Vorbehandlung, wobei eine thermische Zersetzung nicht beobachtet wurde. Mittels der Impulserhitzungsmethode wurden toxikologische Suchanalysen auf flüchtige Substanzen an 452 Proben von 280 Notfallpatienten durchgeführt. Diese Methode hat dabei ihre Anwendbarkeit auf derartige Fragestellungen, aber auch bei der qualitativen und quantitativen Untersuchung von Autopsieproben bewiesen.
    Notes: Abstract The head-space method has commonly been employed as a reliable method for the analysis of ethanol and other volatile drugs and poisons. The pulse heating method is characterized by the following advantages: 1) Analysis can be performed with small samples (1 μl), 2) pretreatment is not required, 3) requires little time, 4) gives exact measurements. Volatile substances can be isolated and identified within 15 min and thermal decomposition has not been observed. Toxicological screening of volatile substances was performed on 452 samples from 280 emergeny patients using the pulse heating method. The pulse heating method could clearly be shown to be useful for the analysis of volatile substances and could be used as an emergency toxicological screening system and for the quantitative analysis of clinical samples obtained from medical emergencies and forensic autopsies.
