Owing to the polychemotherapy treatments the proportion of long-term survivors in adult acute leukemia achieving a complete remission id of about 15 to 30%. this percentage attains 50% in childhood lymphoblastic leukemia. Some long-term survivors may be considered as cured. The chemotherapy of chronic leukemias is disappointing. Because of our limited conventional therapeutic means the allogenic bone marrow transplantation is now indicated in the following instances : the acute myeloid leukemia in first remission, the acute lymphoblastic leukemia (ALL) in second remission or in first remission of poor-risk ALL, and the chronic myeloid leukemia during the chronic phase.

L'agranulocytose médicamenteuse se caractérise par une diminution sévère et sélective des polynucléaires neutrophiles dans le sang circulant. C'est la réaction médicamenteuse conduisant le plus souvent à une issue fatale. Les drogues les plus souvent incriminées sont le pyramidon ou le dipyrone, les sulfamidés, les antithyroïdiens, les phénothiazines, la phénylbutazone et ses dérivés. La vitesse d'installation de la granulocytopénie varie selon le mode d'action de la drogue. Dans les agranulocytoses d'origine immunologique, une prise unique du médicament chez un sujet déjà sensibilisé peut aboutir à la disparition pratiqueement totale des granulocytes dans le sang circulant en l'espace de 6 à 10 heures. A la différence del'anémie aplastique sévère, l'agranulocytose est en principe réversible en l'espace d'une à trois semaines. Son traitement implique l'arrêt immédiat de la drogue, l'hospitalisation en milieu spécialisé, l'administration rapide d'une association d'antibiotiques bactéricides aux doses maximales, et l'isolement en chambre propre ou stérile. L'indication de transfusions de granulocytes doit être discutée. [less ▲]Detailed reference viewed: 279 (3 ULg)

We are reporting the case of a 55-year-old man with stage II chronic lymphoid leukemia, complicated by Herpes zoster ophtalmicus with controlateral hemiplegia. This hemiplegia has been interpreted as the consequence of a granulomatous angiitis. Anti-viral drugs should be useful in the treatment of these cases. [less ▲]Detailed reference viewed: 148 (0 ULg)

The properties of 5 beta-reductase, 5 alpha-reductase and aromatase, 3 testosterone metabolizing enzymes, were studied in the quail brain by an in vitro incubation technique. The results describe the changes in time of metabolite production and the effects of temperature, enzyme and cofactor concentrations. The apparent Km and Vmax were evaluated for the 3 enzymes. Aromatase and 5 alpha-reductase have a higher affinity but a lower capacity than 5 beta-reductase. The kinetics of the latter enzyme are complex and suggest the presence of two types of enzymes. These characteristics fit in well with the role probably played by the enzymes in vivo. [less ▲]Detailed reference viewed: 10 (0 ULg)
Prostaglandines et physiologie de la reproduction humaine et animale.

This review of 417 publications in the literature covers various aspects of the role of prostaglandins in human and animal reproductive physiology. The author points out that there are a variety of prostaglandins all belonging to a family of substances that derive from arachadonic acid. They are present in many human and animal tissues, are extremely labile and are involved in reproduction in the ovary in follicular development and release of the follicle, in the tube in migration of the gametes, and in the uterus in implantation and delivery. The author says that the role of prostaglandins is not an exclusive one but they are linked with the hypothalamo-pituitary hormones, as well as with progesterone and oestrogens. It may be possible that PGE helps to initiate follicular development by stimulating the appearance of LH and FSH receptors. PGE is also luteotrophic. Indomethacin which is a prostaglandin inhibitor however does not modify the ability of LH to stimulate luteinization and maturation of the oocyte. The author postulates on the origin and the identification of the luteolytic factor and gives schematic illustration of the arterio-venous blood supply between the uterus and the ovary which is so important for the good function of the prostaglandins. It is possible that PGF type prostaglandins which are vasoconstrictor may reduce the flow of blood around the ovary, perhaps even specifically to luteal tissue. He postulates that PGF2 alpha in its relationship to its receptors is necessary but insufficient to explain the full luteolytic effect. Turning to the semen he shows that the nature and concentration of prostaglandins in semen varies from one species to another. He thinks that there is a triple role for prostaglandins with semen, which is: a participation in the events of ejaculation, an effect on the female genital tract, and an effect on the mobility of spermatozoa. He speaks of the role of prostaglandins on the Fallopian tubes and believes that they do have an effect on determining the movement of the tubes but cannot explain exactly what.

The first extensive sets of photoelectric observations of the peculiar emission-line star GG Carinae were obtained from 1977 to 1981, in both the standard UBV and Strömgren systems. A Fourier analysis of 767 independent measurements leads to the determination of a period P = 31[SUP]d[/SUP].020 for the light variations. Different physical arguments based on the analysis of the present photoelectric - as well as previous photographic - data clearly indicate, however, that the true period is P = 62[SUP]d[/SUP].039. The resulting composite lightcurve displays two distinct maxima and minima with a total light amplitude Deltam â ¡ 0.5 mag. Additional interesting features are noticed in the mean lightcurve. Although it is not possible to classify GG Carinae among any known type of variable stars, the light variations of this object are similar to those observed for beta Lyrae-type systems.

The acute hemodynamic effects of intravenous diltiazem were studied in 8 patients with coronary artery disease, left ventricular (LV) failure (New York Heart Association functional class III), a rest ejection fraction (EF) less than 40% or a cardiac index less than 2.4 liters/min/m2. Hemodynamic measurements and LV angiograms were performed at rest before and after the administration of diltiazem, 0.5 mg/kg, administered at a speed of 5 mg/min. Diltiazem treatment induced a decrease in heart rate from 68 +/- 12 to 55 +/- 9 beats/min (p less than 0.001). Mean aortic pressure decreased from 94 +/- 14 to 81 +/- 15 mmHg (p less than 0.05). Thus, the pressure-rate product significantly decreased under the influence of the drug, from 8,791 +/- 2,465 to 6,342 +/- 1,808 beats mm Hg/min, (p less than 0.001). Diltiazem induced no significant change of LV end-diastolic pressure, pulmonary wedge pressure, cardiac index and LV stroke work index. Systemic vascular resistance decreased (p less than 0.01), whereas pulmonary vascular resistance showed no change. End-systolic volume diminished (p less than 0.02), which accounts for the increase of stroke volume and ejection fraction (p less than 0.001). Disorders of regional contractility were not aggravated by diltiazem, and even improved in individual cases. Thus, intravenous diltiazem may be used safely in patients with heart failure. However, in view of the marked bradycardic effects seen in some cases, heart rate should be carefully monitored. [less ▲]Detailed reference viewed: 13 (0 ULg)
