    Notizen: Analysis of free nucleotide composition of both avian thrombocytes and pig platelets showed quantitative differences in the level of adenine nucleotides. 3H-adenine taken up by turkey thrombocytes was metabolized mainly to adenine nucleotides was not released after thrombin action. Thrombin liberated non-radioactive adenine nucleotides (18.2 ± 1.5 %, 20.6 ± 1.9%) of the total, probably localized in a storage pool. Malonyldialdehyhyde (MDA) production due to thrombin was observed in both platelets and thrombocytes.

    Shape change of human erythrocytes induced by phosphatidylcholine and lysophosphatidylcholine species with various acyl chain lengths (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Cell Biochemistry and Function 2 (1984), S. 171-176 
    Details
    ISSN: 0263-6484
    Schlagwort(e): Blood ; human erythrocyte ; erythrocyte membrane ; choline phospholipid ; acyl chain ; Chemistry ; Biochemistry and Biotechnology
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Biologie , Medizin
    Notizen: Intact human erythrocytes were treated, under non-haemolytic conditions at 37°C, with synthetic phosphatidylcholine which has homologous, saturated acyl chains of 8 ∼ 18 even-numbered carbon atoms (C8 ∼ C18-PC) or with lysophosphatidylcholine which has a saturated acyl chain of 8 ∼ 18 carbon atoms (C8 ∼ C18-lysoPC). The C8 ∼ C14-PC and C12 ∼ C18-lysoPC species were rapidly incorporated into the erythrocytes and induced a shape change of the crenation (echinocyte formation) type. The site of the incorporation was found to be most probably on the outer leaflet of the membrane lipid bilayer. The extent of the shape change was dependent on the amount of each lipid incorporated. When the same amount of a PC or lysoPC species was incorporated into the membrane, about the same extent of crenation was induced, independent of acyl chain length. However, C16-PC, C18-PC, C8-lysoPC and C10-lysoPC, which were not incorporated into the erythrocytes, did not induce any shape change. It is therefore suggested that the hydrophobic moiety of these amphiphilic lipids may greatly contribute to their transfer from the outer medium into the erythrocyte membrane, but do not influence so much the perturbation of the membrane lipid bilayer which may be responsible for induction of the shape change.

    Synthesis and levels of organic phosphates in erythrocytes during avian development: Specific formation of BPG and IP5 in two distinct populations from young chicks (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Cell Biochemistry and Function 2 (1984), S. 257-262 
    Details
    ISSN: 0263-6484

    Thema: Biologie , Medizin
    Notizen: Two generations of red cells (embryonic and definitive), different types of haemoglobins, and special organic phosphates involved in the control of haemoglobin oxygenation (2:3-bisphosphoglycerate, BPG, and inositol-5-phosphate, IP5), have been found progressively during development of the chick. Levels of both organic phosphates, as well as activities of the enzymes involved in BPG synthesis (2:3-bisphosphoglycerate synthase, BPGM) and IP5 formation (phytase), were studied in the erythrocyte populations from embryo, young and adult chickens. Measurement of specific activities of BPGM and phytase in the two subpopulations present in young chickens showed that these phosphates could be specifically and predominantly formed in these two red cell populations.

    Specific molybdenum binding to spectrin subunits (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Cell Biochemistry and Function 2 (1984), S. 21-22

    Thema: Biologie , Medizin
    Notizen: Molybdenum in the form of its pentavalent complex binds primarily to spectrin when incubated with erythrocytes. Only the band 1 subunit is involved in this interaction thus indicating some structural differences between spectrin subunits.

    Platelet membrane fatty acids in thrombocytosis due to myeloproliferative disorders (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Cell Biochemistry and Function 2 (1984), S. 23-25 
    Details
    ISSN: 0263-6484
    Schlagwort(e): Blood ; fatty acids ; platelet ; membrane ; myeloproliferative disorders ; Chemistry ; Biochemistry and Biotechnology
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Biologie , Medizin
    Notizen: The fatty acid composition of platelet membranes has been analysed in patients with thrombocytosis due to myeloproliferative disorders, who had not taken any drugs. A significant increase in palmitic and oleic acid, together with a decrease in stearic, linoleic and arachidonic acids was observed. The fatty acid pattern of platelet membranes was also analysed in patients during treatment with ASA (acetylsalicylic acid). ASA ingestion completely normalizes the platelet content of palmitic acid and partially that of stearic and arachidonic acid, whereas it has no effect on the level of linoleic acid and raises that of oleic acid. The altered pattern of fatty acids observed in patients may interfere with platelet function by decreasing membrane fluidity. Treatment of patients with ASA seems to act on platelet membranes by partially normalizing the fatty acid composition.

    Nude mice injected with DNA released by antigen stimulated human tlymphocytes produce specific antibodies expressing human characteristics (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Cell Biochemistry and Function 2 (1984), S. 33-37 
    Details
    ISSN: 0263-6484
    Schlagwort(e): Blood ; lymphocyte ; nude mouse ; DNA ; antibodies ; allotype ; Chemistry ; Biochemistry and Biotechnology

    Thema: Biologie , Medizin
    Notizen: Nude mice were injected with DNA purified from the nucleoprotein complex released by T lymphocytes previously exposed in vitro to inactivated herpes or poliovirus. After five days the serum of these mice was tested for its virus neutralizing activity. Results show that injected nude mice synthesize antiherpetic or antipolio antibodies depending on the antigen used to sensitize the T lymphocytes in vitro. These antibodies were not found in the serum of uninjected control mice or mice injected with inactivated herpes or polio viruses. Mice injected with DNA release by human T cells produced antibodies carrying human allotypes since they could be neutralized by anti-allotype sera. Moreover their antiviral activity was inhibited by anti-human IgM or IgG. However, the mice which were injected with DNA released by antigen stimulated murine T lymphocytes produced antiviral antibodies which were not neutralized by anti-human allotype sera.
