Zusammenfassung Frischgefrorene Gewebesektionen verschiedener Gewebe wurden in Kalium-Eisen-Cyanid bei pH 5,2 inkubiert; dabei wurde eine präzise und einzigartige Färbung nur der Zellnuklei beobachtet. Die Ursache dieser selektiven Kernfärbung ist nicht verständlich, doch stellt sie höchstwahrscheinlich eine Färbung von Ferro-Verbindungen in den Nuklei dar.

Summary The reaction of glyoxylic acid withp-nitronitrosobenzene (1b) in dilute aqueous solution gave the hydroxamic acid (2b) as the major detectable product. The significance of this observation with respect to the title reaction is discussed.This study was supported by grant No. CA 32395 from the National Cancer Institute, and by Research Career Development Award ES 00120 from the National Institute of Environmental Health Sciences, DHHS. 相似文献

Summary Following topical application of14C-labeled 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU, carmustine) to the skin of mice radioactivity was found in all viscera and tissues examined. Exclusive of the gut, highest values were recorded for the liver, kidney and lung.Supported by Public Health Service, grant CA 14825, from the National Cancer Institute, National Institutes of Health, Department of Health, Education and Welfare. 相似文献

Summary A novel lipoxygenase was partially purified from the gorgonian coralPseudoplexaura porosa and was found to be specific for arachidonic acid. This soluble enzyme catalyzed the formation of 15-hydroperoxy-eicosatetraenoic acid (15-HPETE) from arachidonic acid.This investigation was supported by PHS grant No. CA32395 awarded by the National Cancer Institute and by PHS Research Carreer Development Award No. ES00120 to MDC awarded by the National Institute of Environmental Health Sciences, DHHS. The authors acknowledge Ms M. A. Russell and Dr D. G. Anderson of the University of Miami for assistance in the collection of gorgonian corals. Preliminary work was conducted at the University of Miami School of Marine and Atmospheric Science. This is journal series No. 3638 from the Florida Agricultural Experiment Station. 相似文献

Zusammenfassung Das Überleben der von der eigenen Mutter und von stammesfremden «Ammen» gesäugten Jungen wurde untersucht an Mäusen der Stämme AKR/Sp, PL/Sp und C57BL/Sp. Die Ergebnisse zeigen, dass die genetische Herkunft der Säuglinge wie auch andere, nicht genetisch bedingte Einflüsse der Mutter auf die Jungen in utero für das Überleben der Jungen ausschlaggebend ist.

Summary Evidence is presented that chromosomal variation inPeromyscus results from 1. addition of heterochromatic short arms to acrocentric chromosomes, and 2. pericentric inversions. Constitutive heterochromatin polymorphisms contribute to variation in the amount of heterochromatin inPeromyscus populations.Submitted in partial fulfilment of the requirements of Master of Science degree in Zoology at the University of Wyoming.Supported in part by Public Health Service Grant No. GM-20491 from the National Institute of Health and by grants from the U.

Summary The guinea-pig,Cavia porcellus, is unusual in possessing plasma L-asparaginase, an enzyme with anti-tumor activity. 21 additional species have been examined as to the presence of this enzyme: the results confirm and extend its remarkably limited species distribution.This work was supported in part by grant GM/CA 25378 from the National Institute of General Medical Sciences, National Institutes of Health.We are grateful to dr Hanna Hensch, Philadelphia Zoological Garden, and Ms Joan Whitla and Dr Richard J.

Zusammenfassung Das antitumoraktive Protein-Antibiotikum Neocarzinostatin wurde mit Dithiothreit in flüssigem Ammoniak reduziert und mit Chloressigsäure alkyliert. Tryptische Spaltung des tetra-S-carboxymethylierten Proteins ergab 5 Fragmente. Die Sequenz von 25 Aminosäureresten im tyrosinhaltigen Fragment H3 wurde durchEdman-Abbau im automatisierten Sequenator ermittelt.

Summary An investigation of the Guyana plantSimarouba amara Aubl. (Simaroubaceae) for antineoplastic quassinoids led to isolation and structural determination of the new quassinoids 2-acetylglaucarubine (1a) and 13,18-dehydroglaucarubinone (2). The previously known 2-acetylglaucarubinone (3a) and glaucarubinone (3b) were also obtained. The new quassinoid2 was found significantly to inhibit growth of the murine lymphocytic leukemia P388.Antineoplastic agents 59. For part 58 refer to M. T. Edgar, G.R. Pettit and T.H. Smith, J. org.

Summary The defensive secretion of the opilionidPhalangium opilio contains 1,4-naphthoquinone and 6-methyl-1,4-naphthoquinone. Naphthoquinones are of rate occurrence in arthropods, having previously been reported only from certain tenebrionid beetles.Paper No. 60 of the series: Defense Mechanisms of Arthropods.Acknowledgments.

Zusammenfassung In Analysen von Gehirn-Zymogrammen verschiedener neurologischer Mäusemutanten wurden Abnormalitäten in Form von Esterasedefiziten gefunden. Da solche neulich auch für die multiple Sklerose des Menschen beschrieben wurden, wird vorgeschlagen, unspezifische Esterasen als signifikant für den normalen Myelinanabolismus zu bewerten.

Zusammenfassung Die gegebenen Befunde lassen vermuten, dass neonatale Thymektomie und/oder Infektion mit LDH-Virus einen Effekt auf eine Anzahl von Faktoren wie LDH-Plasma-Spiegel, Gewichtserhöhung und Lebensdauer in Mäusen hervorrufen können. Der Virustiter im Plasma ist vom Zeitpunkt der Infektion abhängig.

Summary A simple and mild reduction of aflatoxin B1, involving treatment of aflatoxin B1 with ethereal zinc borohydride to give 57–65% yield of diastereomeric aflatoxicols, is described.This work was supported by the College of Agricultural and Life Sciences, the University of Wisconsin, Madison, and by Public Health Service Research, grant No. CA 15064, from the National Cancer Institute, and by funds from contributions of food industries to the Food Research Institute. We are grateful to Professor Dennis Hsieh for a gift of natural aflatoxicol, to Mr William Harder for technical assistance throughout this investigation, and to Mr Gary Girdaukas for taking mass spectra. 相似文献

Summary A precursor of plasma albumin in man was identified in liver obtained from cadaver renal transplant donors. After 30 min incubation with14C-(U) leucine, most of the labeled immunoreactive albumin was identified as proalbumin, as was evident from its characteristic elution profile on DEAE cellulose 52. After an additional 30 min incubation with unlabeled leucine (60 min total), no precursor from could be identified and the label coeluted with serum albumin. These data strongly suggest that human albumin is initially synthesized in a precursor form and is subsequently transformed into serum albumin.This work was supported by grants from the Deutsche Forschungsgemeinschaft, the National Institutes of Health (CA 123896, AM 191241, CA 142940), and the Hochschulstiftung an der Universität Bern.We gratefully acknowledge the excellent technical assistance of Ms Kathleen O'Laughlin and Ms Edith Junker-Riesen. 相似文献
