Apex-dimension loops may provide useful information in patients with acute myocardial infarction because incoordinate contraction and relaxation can be demonstrated. The method could allow assessment of the effects of therapeutic interventions. Fifty consecutive patients with AMI in the coronary care unit within 48 hours after the onset of their symptoms were studied. Simultaneous recordings of the echocardiogram and apexcardiogram, which were of an adequate quality for analysis, were obtained in only 7 patients (success rate 14%). In all these patients, incoordinate relaxation was demonstrated. A major practical drawback of the method is the time needed for recording the basic data requiring 2 investigators. Therefore, because of the low success rate and difficulties in obtaining simultaneous recordings, apex-dimension loops are not practical in most patients with acute myocardial infarction. [less ▲]

Growth-related changes in pulmonary function values (PFV) of cattle were investigated by a cross-sectional study of 40 healthy Dutch Friesian cattle, 3 days to 13 years of age and weighing 37 to 660 kg. Technical and methodologic procedures and body conformation and condition were standardized. A regression analysis was done with 4 independent variables (body weight, thoracic perimeter, body surface area, and age) and with PFV measured in this study. Ventilation values, dynamic lung compliance, and viscous work of breathing changed linearly with somatic growth. Respiratory frequency, total pulmonary resistance, and arterial oxygen tension showed an exponential relationship with all the independent variables. On the other hand, intrapleural pressure values were weakly correlated with body size indexes. The most important growth-related changes in PFV occurred at approximately 1 year of age. A significant (P less than or equal to 0.05) difference between immature and mature cattle was shown for the blood-gas values and the specific values of the breathing mechanics. The dynamic lung compliance/lung weight was lower and the total pulmonary resistance X minute volume was higher in cattle than in other domestic mammals. The regression equation, giving the best fit of the data, was selected for each PFV. [less ▲]

A procedure to standardize the position of an esophageal catheter (eso-cat) tip, used to measure intrathoracic pressure, was tested in ten healthy Dutch Friesians. The cattle were in normal condition with body weights (BW) between 52 and 670 kg and thoracic perimeters (TP) between 80 and 210 cm. The position of the neck and head was standardized. The eso-cat was introduced via the nose into the thoracic portion of the esophagus. The distance between the nares and the eso-cat tip (Lcat), which was positioned between the crossing point with the aorta and the caudal mediastinal lymph nodes, was measured for each animal. The regression equation, calculated between the Lcat and the BW and TP was, respectively: Lcat (cm) = 65 + 0.115 x BW (kg) (r2 = 0.99) and Lcat (cm) = 22 + 0.535 x TP (cm) (r2 = 0.97). The corresponding residual standard deviations were respectively 2.52 and 4.37 cm. The multiple and curvi-linear regression equation did not give a significantly better fit of the data [less ▲]

In this prospective study of 50 patients, 36 of whom developed the adult respiratory distress syndrome (ARDS), early and intense complement activation was demonstrated. These patients were at risk of the ARDS because of multiple injuries, major abdominal surgery, acute pancreatitis, severe burns, or disseminated intravascular coagulation. Abnormal C3 consumption (as measured by the C3d/C3 ratio) and elevated plasma C5a-like activity (as measured by a leukocyte aggregation assay) were associated with, respectively, 84 and 86% of cases of ARDS. Both tests were more sensitive indicators of complement consumption than were assays of total hemolytic complement activity (CH50) or total C3. The C3d/C3 ratio showed a close, inverse correlation with CH50 in 47 healthy subjects, and was increased in 12 control patients after minor surgery. The C5a-like activity was found only in patients at risk of ARDS; it was highly associated with clinical conditions that predispose to the ARDS, but it cannot be considered as a real predictor of ARDS occurrence in these patients. Sequential samples from both sides of the pulmonary circulation showed initial pulmonary clearance followed by the release of C5a-like activity. No simultaneous changes in C3 levels were found, suggesting the possible presence of modulating factors. These observations suggest that other factors (e.g., hypoxia and metabolic cascades) may influence the development of ARDS. [less ▲]

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 ▲]

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 ▲]

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. [less ▲]
