    Natural killer cell activity against a thymoma cell line thy 121 in bone marrow transplant recipients (1986)

    Keywords: Bone marrow transplantation ; Natural killer cells ; Interferon ; Cycloporin A ; Graft-versus-host disease ; Methotrexate

    Topics: Medicine
    Notes: Summary Twenty-one patients with acute and chronic leukemia or severe aplastic anemia were studied for NK activity against a thymoma cell line (Thy 121) before and after allogeneic bone marrow transplantation. The means of the pretransplant and post-transplant levels did not differ from the mean of 134 NK determinations in 67 healthy donors. There was no correlation between pretransplant NK levels and the appearance of graft-versus-host disease. Three weeks following bone marrow transplantation, pretransplant NK levels were observed. The sensitivity of NK cells to interferon was the same as in normal donors both before and after bone marrow transplantation. In contrast to methotrexate, cyclosporin A inhibited NK activity in patients and controls in vitro. In vivo cyclosporin A treatment, however, did not decrease NK levels in bone marrow recipients.

    In vivo induction of HLA molecules in patients with myeloproliferative syndrome during IFNα treatment (1991)
    Springer
    Annals of hematology 63 (1991), S. 259-263

    ISSN: 1432-0584
    Keywords: HLA antigens ; Regulation in vivo ; Interferon ; Myeloproliferative syndrome
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Eighteen patients with myeloproliferative syndrome (14 with chronic myeloid leukemia, four with essential thrombocytosis) were investigated for modulation of HLA antigens on peripheral blood lymphocytes, monocytes, and hematopoietic precursors during IFNα therapy as a sign of potentially increased immune recognition of malignant cells. After 1 month of IFNα therapy, an increased number of monocytes and hematopoietic precursor cells, but not of lymphocytes, expressed HLADQ antigens. In addition, a strong induction of HLA class-I antigens was found on both hematopoietic progenitors and normal peripheral blood mononuclear cells. With daily injections of IFN in the first month of therapy stimulation continuously increased, suggested a major effect of IFNa on hematopoietic progenitors with sustained enhanced expression of HLA class-I antigens during differentiation of myelomonocytic cells. HLA class-I antigen expression was consistently augmented by IFNα in all patients, irrespective of their hematological response.

    Effect of aconitine on the sodium permeability of the node of ranvier (1974)
    Springer
    Pflügers Archiv 349 (1974), S. 133-148 
    Details
    ISSN: 1432-2013
    Keywords: Node of Ranvier ; Sodium Permeability ; Aconitine
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The effect of aconitine (10−5–10−6 g/ml) on membrane potentials and membrane currents of myelinated nerve fibres of Xenopus laevis was investigated. The following observations were made: a) Current clamp conditions: Slow depolarization (10–15 mV), decrease of amplitude and maximum rate of rise of action potential, finally inexcitability. With inward current pulses ‘hyperpolarizing responses’ could be elicited at membrane potentials more negative than the resting potential (E r ). Neither spontaneous activity nor repetitive responses to electrical stimuli were observed. No effects of aconitine were found in Na-free solutions or in the presence of tetrodotoxin. b) Voltage clamp conditions: Development of steady inward current at normal resting potential due to formation of a non-inactivating sodium permeability; heavily poisoned nodes therefore exhibit an N-shaped steady-state current voltage relation with negative slope at membrane potentials more negative thanE r . These non-inactivating sodium channels open more slowly than normal sodium channels, and can only be closed by hyperpolarizing the membrane by about 50 mV. The majority of sodium channels have almost normalτ m; theirm ∞ andh ∞-V relations are shifted by 10–15 mV towardsE r . It is concluded that these changes of the sodium permeability account for the changes of electrical activity observed after treatment with aconitine.

    Die Wirkung von Skorpiongift auf die Ionenströme des Ranvierschen Schnürrings (1968)

    Description / Table of Contents: Zusammenfassung 1. Die Wirkung von Skorpiongift (10−6 g/ml) auf die Ionenströme einzelner markhaltiger Nervenfasern von Xenopus laevis wurde in voltage-clamp-Experimenten untersucht. 2. Skorpiongift beeinflußt sowohl die Natrium- als auch die Kalium-Permeabilität der Schnürringmembran. 3. Die hauptsächlichen Wirkungen des Skorpiongiftes auf die Natrium-PermeabilitätP Na sind: a) Die maximale Natrium-Permeabilität $$\bar P_{_{{\rm N}a} } $$ wird auf 60% ihres an der unvergifteten Membran gemessenen Wertes reduziert. b) Die Natriuminaktivierung wird stark verlangsamt und verläuft in zwei Phasen. c) Der zeitliche Verlauf vonP Na kann unter der Annahme beschrieben werden, daß die Variableh aus zwei Komponentenx undy besteht, deren Zeitkonstanten τ x und τ y 4 bzw. 200 mal so groß sind wie τ h der unvergifteten Membran. 4. Die Wirkungen des Skorpiongiftes auf die Kalium-PermeabilitätP K sind: a) Die maximale Kalium-PermeabilitätP K' wird auf etwa 35% ihres Normalwertes vermindert. b) Der Anstieg vonP K bei Depolarisation wird verlangsamt; zwei Phasen können unterschieden werden. 5. Die Wirkungen auf die Natrium-Inaktivierung und auf die Kalium-Permeabilität können die unter dem Einfluß von Skorpiongift beobachtete extreme Verlängerung des Aktionspotentials erklären.
    Notes: Summary 1. The action of scorpion venom (10−6 g/ml) on the ionic currents of single myelinated nerve fibres of Xenopus laevis was studied in voltage clamp experiments. 2. Scorpion venom was found to affect the sodium permeability as well as the potassium permeability of the nodal membrane. 3. The main effects of scorpion venom on the sodium permeabilityP Na are: a) The maximum sodium permeability $$\bar P_{_{{\rm N}a} } $$ is reduced to 60% of its value in the unpoisoned membrane. b) The sodium inactivation is markedly slowed and proceeds in two phases. c) The time course ofP Na can be described assuming that the variableh is the sum of two componentsx andy, whose time constants τ x and τ y are 4 and 200 times τh of the unpoisoned membrane. 4. The effects of scorpion venom on the potassium permeabilityP K are: a) The maximum potassium permeabilityP K' is reduced to about 35% of its normal value. b) The increase ofP K' upon depolarisation is slowed down; two phases can be distinguished. 5. The effects on sodium inactivation and potassium permeability may explain the extreme prolongation of the action potential under the influence of scorpion venom.
